Universal 50mm viewfinder and guide telescope with a focal length of 220mmExcellent 8x50 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 8x50 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 8x50 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.96 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=1 degree) on the crosshairs are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 8x to 40x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 8x50 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 220mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.96 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 1.0 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 8x to 40x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsSCOPE OF DELIVERY8x50 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

You see better with two eyesThe BRESSER BinoViewer Deluxe makes it possible to observe astronomical objects in a relaxed way with both eyes and with considerably more detail than using one eye. The images created of the moon, planets and globular clusters are particularly impressive. But also with deep-sky objects such as the Orion Nebula the detection of details is much easier. At the same time this binoviewer is very easy to handle. Thanks to the newly patented optical system you can get into focus with any telescope. All you need is a pair of identical eyepieces to enjoy this dramatic and immersive viewing experience.How to use the BinoViewer? Since the BRESSER BinoViewer Deluxe does not require an additional light path (back focus), it can be used with any telescope - including Newtonians and short focus refracting telescopes, which traditionally suffered when using standard binoviewers. No light path corrector or similar accessory is necessary. If a standard 1.25'' eyepiece can be focused, the binoviewer will also work. The eyepiece focal length and field of view size of the eyepieces used are fully retained. As with binoculars one eyepiece is focused first using the telescope focuser. Then the second eyepiece can be brought into focus using the helical focuser on the binoviewer. The required interpupillary distance is then elegantly adjusted to a range of 58–74mm with the help of a linear sliding mechanism, with graduated marker, to help you find your ideal interocular setting quickly.  Self-centring helical eyepiece grips, rather than side-mounted thumbscrew eyepiece retainers are used, decreasing the chance of offsetting collimation of both eyepiece to each other.  The fact that this design of binoviewer uses a well-engineered linear slide mechanism to adjust interpupillary distance, rather than a cheaper-to-produce traditional hinged design also helps retention of collimation.Which objects can be observed with this accessory?Actually, all objects that were previously observed with the telescope in question, but only monocularly with one eye. Because there is no magnification factor at the binoviewer, even low magnifications can be achieved. This makes not only the moon, planets and globular clusters, but also the brighter deep-sky objects very interesting observation targets. The use of two eyes leads to a more relaxed view than using one eye alone.  Although true depth of field viewing at infinity is a little beyond most telescopes and binoviewers, users will note how the human brain attempts to impose depth of field ("3d-like") effects on stereo views through binoviewers.  The biggest difference that most observers comment upon when comparing views through binoviewers like these, as opposed to single monocular eyepiece views, is the extra detail that can be seen in most observable targets.  Relaxed viewing and extra detail in objects are the two main benefits of binoviewing, which the BRESSER Bino Viewer Deluxe 1.25'' delivers in abundance.Also ideal as an accessory for solar telescopesA very special application is the use of the BRESSER BinoViewer Deluxe in combination with all solar telescopes. The spherical shape of the sun with all its surface details is shown very impressively.  The depth of field effects of seeing filaments silhouetted against the solar surface are particularly enjoyable to observe.Important note: Do not use the BRESSER Binoviwer Deluxe without a suitable solar telescope or a safe solar filter in front of the telescopes objective lens . Otherwise, there is an acute risk of going blind.High-quality mechanics and materialsThe entire BRESSER BinoViewer Deluxe is made of high-quality materials. Except for the outer plastic covers all components are made of anodised aluminium. Particularly remarkable are the low-backlash sliding mechanism for adjusting the interpupillary distance and the precise rotary clamping of both eyepiece adapters. The wide clamping surface holds the eyepieces in place securely and also centres them automatically on the optical axis. The one-sided dioptric adjustment has a backlash-free helical drive and enables the finest corrections. For safe transport a high-quality hard-shell transport case is included in the scope of delivery.Which eyepieces can be used?All eyepieces with a 1.25'' barrel and a field stop of up to 22mm. Depending on the interpupillary distance the outer diameter of the eyepiece housing should not exceed a value of approximately 50 mm.Filter thread 1.25'' availableNo 2nd filter sets are necessary to operate the BRESSER Binocular Approach Deluxe. The desired colour or nebula filter can be screwed directly into the 1.25'' nosepiece. in this configuration, when changing the eyepieces to affect a change in magnification, no swapping of filters is necessary.  Unique mirror-lens system with Ohara (Japan) lanthanum glass material The BRESSER Binocular Viewer Deluxe is equipped with a unique mirror-lens system. This has the advantage of higher light transmission and less color aberration. The resulting image is simply brighter and sharper. To achieve this the exclusive Ohara (Japan) lanthanum glass material has been used and in addition all optical surfaces are equipped with a full multi-layer broadband coating. Finally the beam-splitting mirror has a 99% dielectric coating and completes the excellent optical design.FEATURESEnables binocular observations with all telescopesRelaxed and comfortable viewingThree-dimensional viewing experienceSuitable for all telescopes with 1.25'' eyepiece connectionNo additional light path requiredNo magnification factor at the binocular attachmentEven low magnifications with large fields of view are achievableFor observing moon, planets and deep sky objectsPrecise and robust mechanicsSliding mechanism to adjust the interpupillary distanceDioptric compensation via fine helical driveWide eyepiece rotation clamp with automatic centeringFilter thread 1.25'' (M28.5 x 0.6mm) availableLens and mirror design made of finest Ohara (Japan) lanthanum glass materialAdvanced broadband multilayer coating on all optical surfaces99 % dielectric-coated beam-splitting mirrorHigh-quality hard-shell carrying case includedWHAT'S INCLUDEDBino Viewer DeluxeDust capsCarrying case 

The Explore Scientific Two Room Pop-Up Observatory is a useful weatherproof tent that protects your valuable equipment from wind, dew, rain and dust. Most amateur astronomers and astrophotographers dream of having an observatory to keep dust, dew and wind away from their telescope and to shield disturbing stray light from their telescope's optics. But for many astronomers, an observatory is only a dream because of the cost of a roll-roof building or an observatory dome. There is also the problem that an observatory building needs a permanent location that is suitable for an observatory. Portable, quick to set up and inexpensive A good solution is a portable observatory tent. Compared to their fixed counterparts, a tent is extremely inexpensive and can be set up almost anywhere there is a flat surface and a clear view of the sky. However, setting up a portable observatory tent can also be a hassle. No one wants to waste their valuable observing time reading complex instructions while trying to figure out which pole goes where. For this reason, we have used a sturdy pop-up design. Setting up the EXPLORE SCIENTIFIC Pop-Up Observatory can be done in a matter of minutes. By releasing a retaining strap, the complete tent unfolds from its packaging in just a few seconds. You really don't need to do anything other than connect the two observatory rooms with a Velcro seam and attach it to the ground. Thanks to this simple design, the EXPLORE SCIENTIFIC Pop-Up Observatory can be set up and taken down in just a few minutes, giving you plenty of time to enjoy your astronomy weekend. Plenty of space for your equipment and super compact when folded up. With just under 5 square metres of total space and 1.52 metre high side walls, coupled with 1.83 metre high windscreens, the EXPLORE SCIENTIFIC Pop-Up Observatory allows you to set up your computer equipment in one room and the telescope in the other, or set up two complete telescope systems. Each room is 152 by 152 centimetres. Mobile observatory with compact transport dimensions In addition to being easy to set up and take down, another advantage of the pop-up design is that it is travel-friendly, as it is light and easy to stow away. The entire observatory tent folds down to a package 70 centimetres in diameter and 10 centimetres thick. This allows it to be transported in a small car or even on a flight for distant expeditions. And apart from the fact that it allows you to go to your favourite observing site at any time, portable observatory tents are usually the first choice for astronomers and astrophotographers attending star party events.  Advanced materials provide optimal protection and durability However, the fact that the EXPLORE SCIENTIFIC Pop-Up Observatory is lightweight and easy to store and set up doesn't mean it can't withstand bad weather conditions. The Black-Out coated polyamide material is waterproof and offers excellent UV protection. This guarantees reliable protection for your equipment as well as long-lasting durability of the observatory tent. Large doors for convenient use The doors to enter the observatory tent and pass through the attached rooms are very generously sized at 102 centimetres high and 92 centimetres wide, so you can easily walk in and through your equipment. The doors roll down to keep moisture out and their heavy-duty zips will last for years. The extra weather cover protects your gear when not in use. With the large weather cover included, you can protect your gear from the hot sun or a surprise rain shower during the day. Or even from dew at night. The modern, coated and waterproof material keeps all unwanted weather influences away from your equipment. Included are cords and pegs to tie down the tent. The structure also has additional holding straps for the use of heavy-duty straps, which can be purchased at local hardware stores.

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer.

BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

Universal mounting rail for mounting a photo camera on an EQ mount with Vixen GP mount for astrophotography. The EXPLORE SCIENTIFIC camera dovetail rail is made of die-cast aluminium. The dovetail-shaped mounting rail is 45 mm wide (similar to the Vixen dovetail style) and 280 mm long. The matt black anodized surface has a laser engraved scale on one side with a fine graduation with 2 mm increments. This makes it easier to determine the center of gravity when placing the camera on the mounting head. To protect the clamping surface there is a stainless steel clamping plate on the opposite side. The dovetail plate is equipped with rubber inserts at 3 positions. This allows a secure mounting of the camera equipment and prevents unintentional slipping and twisting. The mounting rail has a screw fastening with 1/4 inch photo thread, which is suitable for almost all commercially available camera systems. The screw attachment can be used in 3 different elongated hole positions to adjust a perfect balance. In addition, an adapter from 1/4 inch to 3/8 inch photo thread is also included, so that ball heads with the larger thread version can also be used directly. The camera mounting rail weighs only 250 grams.

The BRESSER USB Motor Focuser for HEX and R&P lets you achieve pinpoint focus on your telescope remotely and without any physical contact – whether you're enjoying a casual visual session or pushing the limits of astrophotography. The EAF works with hexagonal (HEX), rack-and-pinion (R&P) and most other standard focusers, connects in seconds via USB-C, and gives you the choice between manual control via the hand controller and fully automated focusing through your astro software of choice. Hands-off focusing via hand controller The included wired hand controller lets you dial in focus from a distance without laying a finger on the telescope. For astrophotography, this is a genuine game-changer: imaging sessions run uninterrupted and your focus stays locked in from first light to the end of the night. Visual observers will appreciate it just as much – precise focus adjustments on demand, no fumbling in the dark. Autofocus and broad software compatibility The EAF integrates smoothly with the most popular astro software packages. The ASCOM driver covers the vast majority of Windows-based applications, while full INDI and INDIGO support makes it equally at home on Mac and Linux. If your software includes an autofocus routine, the motor will handle everything automatically – a real asset for long, unattended imaging runs.Temperature sensor for sharp results all night long As the night progresses, temperature drops can cause the telescope tube and optics to contract slightly – enough to nudge your focus point off target. The included temperature sensor tracks these changes continuously and, paired with compatible software, compensates for any thermally induced focus shift on the fly. The result: consistently sharp images from dusk till dawn, with no manual intervention required.Please note: The temperature sensor and hand controller cannot be used at the same time. FEATURES Precise electronic motor focuser Plug and Play via USB-C Compatible with HEX, R&P and most standard focusers ASCOM, INDI and INDIGO driver support for maximum software compatibility Autofocus support via third-party software Manual focusing via hand controller Temperature sensor to compensate for thermally induced focus shift Robust aluminium housing SCOPE OF DELIVERY Electric motor focuser Mounting plates Wired hand controller Screws Washers Flexible couplings USB cable Temperature sensor Allen key Manual
