Through IceInSpace and via correspondence with similarly frustrated amateur astronomers I became aware that possibly the Williams Optics 0.8X Focal Reducer and Field Flattener might be a suitable substitute for the Meade FR. The WO 0.8 was designed for the WO range of 66mm scopes and with their smaller aperture I was a bit doubtful that full ...
I used them at f11 (native) focal ration, at f7 with Celestron f6.3 reducer, at f5 with Lumicon Giant Easy Guider reducer, f8.8 with Teleskop Service 0.8x reducer/flattener and f2 with Starizona Hyperstar 3. In all cases there is always some vignetting present, but in all cases it can be easily cured with flat field frame.

The only troubling issue has to do with the ATR8 field flattener/focal reducer. It was advertised as providing "images that are sharply focused out to the very corners of a large format DSLR chip." Although much better than the ST80 (with no flattener), the images still have distorted stars out toward the edges, as seen in this full-size clip ...

Generally the scope is in good condition with just one scratch but no dents as you can see in the pictures it does not in anyway affect the performance of the scope. The Losmandy plate has been drilled out in a few places as I have used it to mount an ST80 but it doesnt affect it in anyway, just to make you aware. Collection only.

Aug 02, 2013 · Recently I purchased the ATX with 65mm objective and the 95mm objective. I already owned the ATM 65mm in HD with 25x50 zoom eyepiece so I decided to do a little comparison. The ATM is the same scope as the ATS but was made with a different metal which made it 2 ounces lighter but I cannot find...

FIELD FLATTENER: Optional. SFFX-1. Flat field with field flattener: 43 mm. The fully illuminated Image Circle with 2.5" focuser is less than 43 mm since this telescope uses a 2.5" focuser. This can be compensated for by taking flats. If you want a true full-frame 80 mm, a 3" focuser is required. The ST80 is a fairly fast F5 scope. What this means is the telescope will give brighter views than say a slower F12 or even F7 telescope at a trade off of magnification. ...
