Product Description
The Stellarvue SVX080T features an 80 mm f-6 (480 mm focal length) fully multi-coated, 3-element objective lens with a super low dispersion center element.
Optics: SVX080T is rated at .97 Strehl or higher as measured on our Zygo Phase Shifting Interferometer in red light. Visit our SVX Optics Page to learn more about this process.
Waiting Period: This telescope is now available when ordered with the standard Stellarvue focuser. If ordered with the Feather Touch or Moonlite focusers there may be a delay as these focusers are sometimes backordered. Call us if you have any questions: (530) 823-7796.
Visual Version: This of our 80 mm Apo Triplet. It Includes:
- Our Stellarvue 3" focuser with 2" and 1.25" visual adapters.
- Solid one-piece rings that are bolted to the tube to eliminate felt flexure.
- C020 case to hold the telescope with rings and rail.
- Your choice between the Losmandy style TP009 or the Vixen-Style TP012 mounting rail.
- Handle: The Stellarvue #HAN-2 handle is included.
- Our Stellarvue 3" focuser with 2" and 1.25" visual adapters.
- Solid one-piece rings that are bolted to the tube to minimize tube flexure.
- Risers so the telescope is placed above the mount so a camera will fit.
- Your choice between the Losmandy-style TP013A or the Vixen-Style TP012 mounting rail.
- Handle: The Stellarvue #HAN-2 handle is included.
- C019 Case to hold the assembled telescope with risers and rail attached.
- The SFFX-1 field flattener that is essential for photographic imaging.
- Bahtinov mask to assist in focusing.
The imaging version is valued at $557.95. It is only $400 when ordered as an option above with the telescope.
Each lens uses extreme broadband coatings on each surface enhance it even further. The stars appear vivid and the background, velvet black. Since these coatings transmit more than 99% in and beyond the visual spectrum, reflections seen on CCD images are eliminated.
Tube and dew shield: This telescope comes with an aluminum tube and dew shield that is precision machined, tumbled and black anodized. The inside of the main tube assembly is painted "Ultra-flat Black", and the focuser is baffled with ridges to minimize tube wall reflections. Fittings are black anodized aluminum. The dew shield retracts, reducing the length of the telescope for storage. Extending the dew shield minimizes dewing of the objective at night and serves as a glare shade during the daytime.
Risers and Rail for use with a Camera (Imaging Version Only): When adding a camera, a rail must be added to slide the system forward in order to counterbalance the additional weight. Risers allow the camera to rotate without running into the rail.
Rings: Solid 6061-T6 aluminum rings bolted directly to the tube to eliminate any felt flexure. This is unique to the telescope. Each ring has a total of 12 1/4-20 threaded holes placed on four sides to facilitate the addition of controllers, guidescopes, handle and other accessories.
Field Flattener for Imaging (Imaging Version Only): The SFFX-1 flattener included in the purchase price of the telescope is optimized to work with DSLR cameras that have an over-sized 48 mm t-ring. This modular flattener can be used with various optional adapters, making it compatible with CCD and CMOS cameras that may have a different back-focus. The SFFX-1 attaches directly to the draw tube by unthreading the 2" visual back and threading the SFFX-1 in its place.
If your camera has a different back-focus, call us at (530) 823-7796 and we will advise you on what you need to use this flattener with your camera. In most cases, we can also modify the flattener so it will work with your particular camera, eliminating the need to purchase expensive custom adapters.
For visual use, the Stellarvue Optimus eyepieces and our 2" quartz mirror star diagonal are recommended.
Two-year warranty and Stellarvue service: Stellarvue telescopes and accessories are covered by a two-year warranty. After warranty expires, Stellarvue can repair your telescope if it is damaged for a nominal fee.

SVX80T-3SV APO Triplet
I had this scope out the other night during one of the few non-rainy evenings we've had recently in Santa Cruz, CA. I used it first in visual mode without the .74 field flattener. The wide field view of the Orion complex was spectacular! The stars were pinpoints of light against a very dark background. The contrast was amazing, as it should be for a device measured to have a Strehl ratio greater than 0.98. Next, I removed the visual back and attached the 0.74 flattener/reducer followed by my camera, a QHY168C color CMOS camera with a 16 MP APS-C chip (28mm diagonal). As far as I could tell from the test shots I took, stars were pinpoint out to the edge of the sensor's image circle. Once I learn how to properly focus the camera using the tools available in the acquisition software and record the images in full Raw16 mode, I will post some color pictures. My only minor criticism of the hardware is that the 3" Stellarvue R/P focuser is not as smooth as the Feathertouch focuser on my other Stellarvue refractor. I plan to install an Optec motorized unit to replace the manual focusing knobs in order to get a more precise focus. But I am very happy overall with the optical performance of the OTA. Thanks for the extra figuring you Stellarvue people do to achieve scopes with exceptional Strehl ratios.

Just recieved the scope yesterday. Nicely packed. Had a quick look last night and Sirius was a nice blue with no hint of CA. Beautiful optics. The fit and finish of this scope is top notch. I did need to tweak the focuser a little, but now it operates smoothly. It had a bump to it when focusing in a few spots. The whole rig is extremely solid with the fixed rings. The risers do push the scope out a bit, so a little extra counterweight is needed, which is fine on an equatorial mount. I really like that all the camera attachments are threaded, very sturdy. Now I just need to wait the requisite time for the clouds to disperse so I can put a camera on it.
