Product information "EXPLORE SCIENTIFIC Extension Ring Set M48x0.75 - 5 pieces (30, 20, 15, 10 and 5 mm)"

Five extension tubes from 30 to 5mm length with thread connection M48x0,75mm in a set.

For adjusting different distances of the camera to the focal plane of the telescope or the corrector/field flattener. There is an M48.0,75 internal and external thread in each individual tube. The M48x0.75 thread is also called large T2 photo thread or 2.0 inch filter thread. Camera specific bayonet adapters or color and nebula filters can be used. Included are 5 different tubes with the steps 30, 20, 15, 10 and 5 mm. The larger free inner diameter of 45.0 mm effectively prevents undesired vignetting of the camera sensor. The outer diameter of the sleeves is exactly 50.65 mm and can therefore be mounted directly in any 2 inch diameter eyepiece adapter.

EXPLORE SCIENTIFIC Zero X Field Flattener 2''/M48 for ED80, ED102 and ED127 APO

Field flattener without reduction factor for Explore Scientific ED80 , ED102 and ED127 APO Refractors The imaging plane of many telescopes is not flat but curved. This means that only the area in the centre is perfectly focused - the edge becomes blurred. The human eye can usually compensate for this image property, but a camera shows increasing blurriness towards the edge of the image field. The Explore Scientific Zero X field flattener eliminates the field curvature in many telescopes with a focal length of approx. 480 to 952 mm. The Zero X field flattener was calculated and developed for Explore Scientific ED80, ED102 and ED127 apochromats with focal ratios of F=6.0 and F=7.5. The image sharpness at the edge is dramatically increased. The stars appear round and no longer distorted - a clear benefit for the whole image aesthetics. The Zero X image flattener can be used not only with Explore Scientific Apos, but also with many other Apos. This flattener does not change the focal length of the telescope. Correction for up to full-frame camera sensors (24x36mm) The Explore Scientific Zero X image flattener has been developed due to the rapid development of ever larger camera sensors. With it, there is finally a field flattener available that illuminates and corrects the field of view for full-frame camera sensors up to 24x36 mm. How to use the Zero X field flattener with M48 thread connection This field flattener has a 2 inch (50.8 mm) plug-in connection on the telescope side, with which it is inserted into the telescope instead of an eyepiece or star diagonal mirror. On the camera side, there is a standardised M48 x 0.75 mm connection thread. This M48 connection thread offers a larger free inner diameter than the usual T2 (M42) thread and prevents vignetting when using large camera sensors. With an optionally available and camera-specific adapter ring, a DSLR camera can be connected to it. The working distance is already set at 55 mm. Of course, mirrorless cameras or special astro cameras can also be used with the M48 thread connection. For this, the appropriate M48 spacer sleeves or adapters are additionally required to set the right working distance of 55 mm. This must always be done with every corrector or field flattener so that the best possible field flattening is achieved.Filter thread on telescope side availableThe telescope-side 2.0 inch plug-in sleeve has an M48x0.75 filter thread (internal thread). Individual 2.0 inch colour or nebula filters can be inserted here to increase the contrast of the images.FEATURESField flattener for Explore Scientific ED80, ED102 and ED127 APO telescopesRemoves field curvature from telescopesProduces round stars even at the edge of the image fieldImage sharpness at the edge is drastically increasedA clear benefit for the whole image aestheticsCorrection of field curvature for up to full-frame camera sensors (24x36 mm)Image field flattener without reduction factorOn the telescope side with 2 inch (50.8 mm) plug-in connection and M48x0.75mm filter threadCamera side with large M48 threaded connectorWorking distance of 55 mm between field flattener and camera sensorFor telescopes with a focal length of approx. 480 to 952 mmOptimised for telescopes with focal ratios from F=6.0 to F=7.5Can also be used for various other APOsFully multi-coating on all lens surfacesHousing made of lightweight aluminium, black anodisedAluminium dust cap for M48 threadSCOPE OF DELIVERYZero X field flattener (1 piece)Dust caps

BRESSER T2 Extension Tube Set

Set of 5 extension tubes with T2 thread on both sides for exact distances and secure hold of cameras for astrophotography. Also comes with SC to T2 thread adapter.In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes, will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2 plug-in diameter (item no. 0510365).However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or RitcheyChrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.FEATURES5 T2 tubes with lengths from 5 mm to 30 mmCombination of tubes allows you to obtain distances of 5 mm to 67.5 mmFor exact camera distances in astrophotographyDELIVERY CONTENT5x T2 extension tubes (5/7.5/10/15/30 mm)1x SC to T2 thread adapter

BRESSER Camera-Adapter M35/T2 for MC/MCX100/127

Camera-Adapter M35/T2 for Bresser MC/MCX-100 and MC/MCX-127 Maksutov telescopes The BRESSER Camera-Adapter M35/T2 for MC/MCX100/127 is principally designed to connect a DSLR camera (with appropriate manufacturer-specific T2 T-ring, available separately) to the Bresser MC-100 and MC-127 Maksutov telescopes which have a built-in M35 connecting thread. You can also use wider-bodied astronomical cameras (non-c-mount), which have T2 threads built into their bodies, as standard with this camera adapter. This adapter can be separated into two different lengths of 30mm and 80mm (which both truncate in a T2/M42 thread). The use of these different lengths of extension tube allows the user to vary the projection of image on to a camera chip and get the best framing for the size of object being imaged. Please note: an extra camera specific T2-adapter ring (Canon, Nikon, Sony, etc.) is necessary to connect a DSLR. Many of these are available from us and you are welcome to contact us for advice if unsure which of these to pick.WHAT'S INCLUDED Camera-Adapter with M35x1,0mm to M42x0.75mm (T2) thread

EXPLORE SCIENTIFIC Deep Sky Astro Camera 16MP

High resolution deep sky camera with large Panasonic CMOS sensor and active cooling. Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC DEEP SKY ASTRO camera you get a modern complete package for the comfortable shooting of astro photos and videos. Finally, an easy-to-use camera for capturing galaxies, star clusters, the moon and even planets with high resolution and low sensor noise. Thanks to the fast USB 3.0 computer interface, all image data is transferred within a few seconds. Long waiting times are now history. Simply connect the camera to your telescope using the T2 female thread (M42.0.75mm) or the supplied 2" (50.8mm) plug-in adapter and after installing the drivers and the included EXPLORE Capture recording and editing software, you are ready to take the first real astro photos with a highly specialized camera for your application. The EXPLORE Capture Pro software included in delivery not only offers the basic functions required for image and video capture, but also many helpful special functions for image post-processing and camera setup. Functions such as live image display, exposure settings, white balance, dark image print, stacking, timelapse recording and much more can be configured individually. Especially the very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. If you like, simply switch off the automatic settings and gradually dare to adjust the individual professional settings. The new EXPLORE SCIENTIFIC DEEP SKY camera has a highly sensitive and very low-noise Panasonic CMOS sensor which is additionally cooled down to 40°C below ambient temperature by the two-stage thermoelectric cooling. In contrast to normal DSLR cameras, this guarantees much lower noise and fewer hot pixels in your shots. The images are not only much sharper and more brilliant, but also contain more usable image information. Through the controlled setting of the desired camera temperature, the creation of dark frames under reproducible shooting conditions is possible at any time. The large-format CMOS sensor with 21.9mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The camera has a built-in USB hub with 2 x USB2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable spaghetti and cable breaks. Separate cable connections between your accessories and your computer are no longer necessary. A sturdy hard case for the camera plus accessories is also included. IMPORTANT NOTES: Don't get confused by the megapixel data and the contrary price structure. In the field of astronomy, the key criterion is not the sensor resolution but the maximum light sensitivity. The main goal is to capture as much light as possible in a short time.DOWNLOAD latest camera software and drivers see download folder "Manuals" or here: http://www.touptek.com/download/showdownload.php?lang=en&id=2 Sample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 151´x 114´ (2.5 x 1.9 degrees) 500 mm - 121´x 91´ (2.0 x 1.5 degrees) 600 mm - 101´x 76´ (1.7 x 1.3 degrees) 700 mm - 86´x 65´ (1.4 x 1.1 degrees) 800 mm - 76´x 57´ (1.3 x 0.9 degrees) 900 mm - 67´x 51´ (1.1 x 1.9 degrees) 1000 mm - 61´x 46´ (1.0 x 0.8 degrees) 1250 mm - 48´x 37´ (0.8 x 0.6 degrees) 1500 mm - 40´x 30´ (0.7 x 0.5 degrees) 1750 mm - 35´x 26´ (0.6 x 0.4 degrees) 2000 mm - 30´x 23´ (0.5 x 0.4 degrees) FEATUREScamera type: ASTRO Camera 16.0MP ATR3CMOS16000KPA data output: single pictures and video image Sensor: Panasonic NM34230PLI CMOS Color Sensor adjustable resolution: 4648x3506 / 2304x1750 / 1536x1168 adjustable binning: 1x1 / 2x2 / 3x3 frame rate per second (FBS): 22.5 / 43 / 48 physical sensor size in pixels: 4648 x 3506 megapixel: 16 MP sensor size: 17.6 x 13.3 mm (4/3 inch) pixel size: 3.8 µm x 3.8 µm bit depth: 12 Bit backfocus: 17,5 mm shutter Type: rolling shutterinternal camera memory: DDR 3 RAMthermoelectric cooling with fan: yes, up to 40°C below ambient temperature adjustable exposure times: 150µs to 60min operating temperature: -10 to +50°C (30-80% RLH) cable length USB 3.0: 150cm DC cable length power supply: 200cm CNC machined aluminium housing camera diameter: 80mm; length: 102mm camera weight: 0,53 kg camera connection diameter: 2.0 inch ( 50.8mm) camera connection thread: T2 (M42x0,75mm) filter thread: Yes, 2.0 inch in receptacle camera connection to PC: USB 3.0 built-in USB hub with 2 x USB 2.0 ports power supply: Power supply 12 Volt 3,0 Ampere included software: EXPLORE Capture included camera driver and ASCOM driver includedoperating system: WINDOWS 10 + 11 PC requirements: CPU Intel Core2 2.8Ghz or higher / 2 GB Ram / USB 3.0 SCOPE OF DELIVERYDEEP SKY ASTRO Camera 16.0MP telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm power supply 230V/12V3,0A dust cap software CD hard case instruction manual
