Suited to astrophotography and visual use, the ED 80mm f/7 Doublet APO Refractor OTA from StarField features a doublet apochromatic lens system with extra-low dispersion glass for clear, bright, high-contrast images with true color rendition. Its two-speed brass rack-and-pinion focuser allows fine focusing and supports 1.25" and 2" eyepieces as well as hefty CMOS or CCD cameras and accessories. The OTA comes with a wide-angle 20mm eyepiece, a finderscope, and a 2" diagonal. It requires a tripod and mount for use, which are sold separately.

      Related Questions and Answers

      Q: 1. In your preview of the telescope were four pictures of what the telescope sees. What do I need to do to see things that clear. What do I need to be able to photograph what I see thru the telescope eyepiece?

      A: Pictures like the ones you see are taken with camera attached directly to the Optical Tube Assembly (the telescope without diagonal or eyepiece). To do this with the EVO72, these are the devices you would need: BH# SKE72EDRCA, SKFRFP80 and the correct SkyWatcher M48 adapter for either Nikon, Canon or Sony E mount camera.

      Q: 2. What do I need to photograph with my Nikon D610?Does it match directly with camera body?

      A: Here is the ideal setup for using the Nikon D610 DSLR Camera on the Sky-Watcher Evostar ED APO 72mm f/5.8 Refractor Guidescope (OTA Only). First on the telescope would be the Sky-Watcher Reducer/Corrector Adapter for Evostar 72ED, BH #SKE72EDRCA (https://bhpho.to/3t8G963). This will allow us to then use the Sky-Watcher 0.85x Focal Reducer/Corrector for ED80 Telescope, BH #SKFRFP80 (https://bhpho.to/3N063AZ). Then use the Sky-Watcher S20301 M48 Camera Adaptor for Nikon, BH #SKCAN (https://bhpho.to/3PSHjN2).

      Q: 3. How to mount it on C11 OTA? What accessory do i need?

      A: A mounting cradle-ring assembly clamps over the OTA and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and to help with balancing, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any mount head with a Vixen-style saddle.

      Q: 4. what size filters does this scope use?

      A: This Scope takes 1.25" Eyepieces. So 1.25" Filters will work on those Eyepieces.

      Q: 5. I have a approximately 2003 version of the Celestron CGE 1100 with computerized mount. Will the Esprit 80 mm scope fit onto this mount?

      A: Unfortunately your mount will not work with this scope. You would need a Altazimuth Mount. A nice Motorized Mount you could do is the Sky-Watcher AllView Mount. Website link: http://bhpho.to/1HZzX1D

      Q: 6. Can this telescope be mounted on a Sky-Watcher Star Adventurer GTI Mount ?

      Q: 7. Mounting rings for the TV-85? You need these AND a mounting plate for this scope.

      A: For the Tele Vue TV-85 85mm f/7 APO Doublet Refractor Telescope, the B&H # TEVSM MFR # AVT-1011 is needed to mount it to a standard Vixen style telescope mount or the BH #TE3RMS • MFR #RS3-8003 is needed to mount it to a standard 1/4-20 tripod.

      Q: 8. Can I use this as a telesope, or is it some kind of accessory?

      A: The Sky-Watcher Evostar ED APO 72mm f/5.8 Refractor Guidescope (OTA Only) can be used as a telescope too but most people are using it as a guidescope or for deep space imaging with a camera.

      Q: 9. What do I need to use a Nikon 5100 with this telescope?
