That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

EXPLORE SCIENTIFIC Camera-Ring M48x0.75 for Nikon
Camera specific bayonet adapter (camera ring) for Nikon DSLR with M48x0.75 mm internal thread for astrophotography. By using the large thread M48x0.75 mm, the vignetting of e.g. a DSLR full format sensor is effectively avoided. Compared to the small T2 thread M42x0.75, this adapter has a free inner diameter of 41.2 mm. This camera ring is made of matt black anodised aluminium and weighs only 30 grams. The light path (overall length) is 8.0 mm. FEATURES Camera-specific bayonet adapter NikonLarge female thread M48x0.75 mm Free inner diameter of 41,2mm No vignetting for full format sensors Light path (overall length) is 8.0 mm Made of matt black anodized aluminium Weight only 30 grams SCOPE OF DELIVERY Camera ring for Nikon (1 piece)

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 Messier NT203s/800 EXOS-2 PMC-Eight GoTo Telescope Set
An optimal set for ambitious astrophotographers: the BRESSER Messier NT203s/800 Telescope with EXOS-2 PMC-Eight GoTo Mount. With its short f/3.9 focal ratio, this 203-mm telescope with a parabolic primary mirror allows deep sky imaging with short exposure times. The large 85 mm secondary mirror ensures optimal field illumination, while the high-quality 2.5" Hexafoc focuser enables vignetting-free photography. The modern mount impresses with its precise GoTo control and easy operation via the ExploreStars app, ensuring accurate tracking and intuitive sky navigation. The Telescope The BRESSER Messier Newton Telescopes have established themselves as reliable workhorses for astrophotography in recent years. With the Messier NT203s/800 with Hexafoc, we present the latest generation of these devices. The photo-Newton with a parabolic primary mirror and a fast focal ratio of 203 mm (8") f/3.9 enables deeper exposures in the same amount of time. The large 85 mm secondary mirror guarantees optimal field illumination, and the high-quality 2.5" Hexafoc focuser ensures vignetting-free photography. The tube rings with a 44-mm universal dovetail bar and handle with camera mounting option, along with an excellent bright crosshair finder, round out this high-quality device.The focuser can also be upgraded with a 10:1 reduction gear (Art. No.: 0625720). For pinpoint star imaging, the optional HR Coma Corrector (Art. No. 0510330) can be used. This is designed for both visual and photographic use, significantly improving image quality, especially in the outer areas of the field. The Mount The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo Mount is equipped with a modern and highly precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and a ST-4 compatible autoguider port is also available. The control system also supports micro-step operation to ensure precise tracking. Intuitive operation via app and graphical star map The ExploreStars app, specifically developed for the PMC-Eight system, impresses with its well-designed, intuitive graphical interface. The current alignment stars for control initialization, as well as all celestial objects in the database, are displayed as a star map with additional text information. All these objects can be conveniently viewed and selected. Powerful controller unit with Open GoTo for customization At the heart of the controller unit is a fully autonomous 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This allows remote operation via browser, ASCOM, app, or serial connection. With Open GoTo, custom firmware can also be written and loaded into the controller unit, allowing customization of device functions and the creation of custom object lists, etc. Polar finder included The included and pre-installed polar finder scope enables quick and precise polar alignment for long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the user experience of the polar finder.
