![]() Previously I have seen a lot of fantastic images taken using the Astro Tech RC6, or ATRC6. Similar variations of this particular Ritchey-Chrétien model exist, each with its own particular flair. The Knife Edge Light Baffles on the Photron RC6 I’ll take all the help I can get when it comes to reducing the negative effects of light pollution from home. Light baffles are present in most of the astrophotography telescopes I have used, but its a nice feature nonetheless. In a long exposure photo, the smallest amount of stray light can become quite bright, and it reduces the overall contrast of your image. Its steel tube includes internal knife-edge baffles that reduce the stray light entering the objective of the scope. The iOptron Photron RC6 was built for astrophotography. I have not experienced this phenomenon myself (or I didn’t notice), but perhaps any readers who have used a Newtonian reflector can weigh in on this subject in the comments. The design of the fixed primary mirror is said to eliminate the image shift that other telescope designs can suffer from. This is a nice touch for a telescope that will need to execute precision adjustments when in use for deep-sky astrophotography. The Photron includes a 2″ dual-speed Crayford focuser. ![]() The RCT sitting in my backyard is just a few meters smaller than the HST, but the little iOptron Photron has the heart of a champion. The Ritchey-Chrétien design is known for its great imaging performance, which is why you’ll find this design used in large professional telescopes including the Hubble Space Telescope. ![]() What is an RC Telescope? Discussion on Quora Mounting the tube to my equatorial mount is quick and easy, as the stubby design of the RC6 is compact and easy to manage. Quite an impressive feat for a modest 6-inch diameter telescope with a conveniently stocky design. By design, an “RC” telescope uses hyperbolic primary and secondary mirrors.Ĭompared to a traditional Newtonian reflector design, this RC6 is said to offer coma and chromatic aberration-free results. The iOptron Photron RC6 is a Ritchey-Chrétien telescope, the first of its kind to ever grace my backyard. Deep Sky Astrophotography with the iOptron Photron RC6 (Video) The increased magnification means that smaller galaxies will appear in higher resolution, and take up more real estate in the frame. A Ritchey-Chrétien telescope is a much better fit for smaller deep-sky targets, including many of the galaxies up for grabs at this time of year. Until now, I’ve only photographed galaxies through wide-field imaging telescopes such as refractors and Newtonian reflectors. These issues are not nearly as apparent when dealing with wide-field refractors, and one of the countless reasons I recommend them to beginners.Īlthough the iOptron RC6 telescope presents a new learning curve, it also means that I’ll be photographing a deeper view of space than ever before. Added challenges include a strong need for an effective plate solving solution, as locating deep sky objects at this magnification can be very time-consuming. With this added “reach” also comes an increased demand for focus and tracking accuracy. ![]() I’m looking forward to some large, high-resolution images of galaxies such as the Pinwheel Galaxy. The impressive 1370mm focal length means that this stocky red Ritchey-Chrétien is a perfect choice for astrophotography during galaxy season. This telescope has a longer focal length than any of my refractors, which I plan on putting to good use.
