Another winning combination offered by Orion – the Sirius ED102T CF EQ-G GoTo Triplet Refractor will astound any amateur astronomer or astrophotographer. Whether you’re looking for a sweet rig to use for stunning visual observations, or an awesome astrophotography setup, this telescope and mount combo gives you the building blocks to do it all in style! In fact, this is perhaps the ultimate package for anyone looking for a telescope system that can be used to achieve great results for BOTH imaging and visual use.
Let’s start by looking at the telescope. Our gorgeous Orion ED102T CF refractor is a state-of-the-art instrument featuring superb triplet apochromatic optics in a beautiful carbon fiber tube. The 3-element air-spaced objective uses esteemed FPL-53 extra-low dispersion glass for true-color performance and clear, tack-sharp views. Your images and views alike will be of the highest quality. Its f/7 focal ratio and 102mm aperture make it a very versatile telescope, able to perform admirably on a wide variety of celestial objects. The huge 3” Crayford focuser can easily support large format imaging cameras without vignetting, even when using astrophotography cameras with sensors larger than 35mm. The machined focuser is equipped with precise dual-speed (11:1) adjustment knobs for pleasing visual or astrophotographic performance, and can be rotated relative to the optical tube. Knife-edge baffles in the telescope maximize image contrast, and the strong yet lightweight carbon fiber tube minimizes thermal expansion during long variable-temperature imaging sessions so your camera or eyepiece remains focused. The ED102T CF refractor's carbon fiber dew shield can be retracted for transport and storage, and a handy thumbscrew lock keeps it positioned right where you want it. Hinged tube rings and a dovetail mounting plate are included as well as a thread-on objective dust cap. The optical tube accepts the standard Orion dovetail mounting base (sold separately) if you wish to attach a finder scope.
Now let’s talk about the GoTo mount that’s included. The Sirius EQ-G has become a fan-favorite mount amongst amateur astronomers thanks to its precise performance, convenient portability, and substantial payload capabilities. Internal dual-axis stepper motors offer meticulous tracking of celestial objects for great astrophotographic performance. The GoTo system allows you to select from among 42,900 celestial objects to explore visually or capture photographically using the intuitive menus on the hand controller. You can even take a tour of the finest celestial showpieces to see what objects you’d like to explore in more detail or photograph. Weighing in at just 32 lbs. (43 lbs. including counterweight)this is one pleasantly portable GoTo mount that can be taken just about anywhere dark skies beckon with minimal fuss. The Sirius EQ-G GoTo Mount’s 30 lb. load capacity is easily capable of holding the ED102T CF refractor along with a host of astrophotography accessories or visual-use gear. The Orion Sirius Mount includes an illuminated polar-axis telescope, and one 11-lb. counterweight. The included tripod is remarkably sturdy, as evidenced by the 1.75"-diameter stainless steel legs and cast-metal spreader plate.
