Visit - Thank you again to all our judges #solar #skywatcher #sun See More See Less All shortlisted entries have now been listed for the peoples choice awards, an opportunity for you to choose your favourite image. Well done David on the title and enjoy your new Skywatcher Star Adventurer GTI Congratulations to all winners. The filter was cut from transparent glass treated afterwards for 95% UV and 98% IR blocking. The custom made IR/UV cut filter, sits on the nose of the Mak on the objective lens. The Quark was set to the highest “blue” setting. The large prominence was imaged first, then the Chomosphere was imaged at a much lower gain setting. This image was captured using a Skywatcher 127 Maksutov, a custom made IR/UV cut filter, and the adaption of a Dedicated Quark Chromosphere Solar filter. The faint red afterburn can still be seen extending approx another 60,000 kms further out from the main flare. What I captured here is still quite amazing at a distance of about 180,000kms.

I was lucky enough to image this at only moments after the large ejection which when was at full blast, actually extended 1.4 million miles out from the sun. David’s comments, This was a very challenging one to capture, because the prominence flare moved so fast, in such a short period of time. Congratulations to David Gray with his entry titled, A message from the sun - dont forget who is boss which was chosen by our judge Please visit David’s page to see his amazing work David Gray is an amateur, passionate award winning Astrophotographer.�His images are taken from his backyard in Perth, Western Australia. We’re pleased to announce that David Gray from Western Australia is the 2023 Sky-Watcher Australia Solar System Astrophotographer of the year. The OTA is also visually a real gem, featuring an elegant design for the both OTA and finder scope in an aesthetically pleasing shimmering black.

The Sky-Watcher EQ-6 Pro mount is highly recommended for astrophotography. The selection of mount depends on how the OTA is to be used. At only 10kg in weight, the OTA can be used on a large range of mounts. Heavy cameras can also be safely attached. A 2 inch ball bearing Crayford focuser, with 1.25 reduction ratio, allows accurate focusing. The half format chip, as is common in Canon EOS cameras, gives an image field of 1.4° x 1°. The 1000mm focal length means most objects can be imaged adequately. The F5.3 focal ratio of the telescope is photographically ‘fast’, permitting relatively short exposure times. The 58mm wide secondary mirror allows a very good field illumination. The use of diffraction generating secondary mirror spider vanes can also be avoided due to the meniscus lens. once the OTA has cooled down there are no air turbulence to interfere with astrophotography. This type of telescope is a so-called ‘closed system’, i.e. Also, this type of system does not generate any irritating colour fringes as is common with achromatic objectives. The advantage is obvious, because a Mak-Newtonian is many several times cheaper to buy than an apochomat. The image produced is quite similar to that of an apochromat. the Canon EOS) – very important for the aesthetics of the image.Įven close to the edge of the field of view, stars are imaged as points and not as ‘comets’. Astrophotographers can obtain coma-free, flat-field photos with a CCD camera or a DSLR (e.g. This telescope has been specifically optimised for astrophotography and offers excellent correction over the entire field of view. Although at first sight it is externally similar to a Newtonian telescope, it offers completely different imaging properties. The Maksutov-Newtonian design is a modification of the Newtonian design in that it has a spherical primary mirror with a front-mounted, coated meniscus lens. The telescope is excellent for very high-contrast Lunar and planetary observing, but also offers great performance for DSO observing. With a 190mm aperture, the telescope collects about 740x more light than the naked eye alone (for a 7mm fully dilated pupil). The front Maksutov lens from Schott ensures that the telescope provides a very good image. The Sky-Watcher 190/1000 Premium Photo Reflector Maksutov-Newtonian OTA telescope offers a high light gathering power and extremely high performance for astrophotography and for visual observing.
