United StatesI use this for imaging with my 150 mm F10 Intes-Micro Mak Cas. Unlike Celestron and Meade focal reducers this offers no correction which is perfect for my Mak/Cas since the field of view is flat to begin with.
I agree with previous comment about cleaning a spot on the lens. I tried cleaning a spot from the lens, using Baader optical wonder solution kit, and damaged the, apparently, very delicate coating.
This focal reducer fitted as advertised and will be good for visual observing, however I am a disappointed with the amount of coma present in the outer edges of images. The centre produces nice crisp round stars gradually degrading toward the edges.
The Antares focal reducer worked satisfactorily to get a wider visual field with my Meade 12 inch LX90. Unfortunately I tried cleaning a spot off from the rear lens, using Mead's recommended lens cleaning solution and plain kleenex, and damaged the, apparently, very delicate coating.
I have bought this focal reducer for use with a Meade LT6 and Meade DSI II camera. The results are abolutely great: there is no distortion whatsoever in the FOV of the camera, and the gain in imaging speed and FOV is impressive. It also worked in visual tests, with only some stars at the extreme edge of low-powered eyepieces becoming slightly distorted. An excellent product.
Unfortunately, I did not enjoy the same results with the Antares Focal Reducer as the previous review. Using moderately wide 26mm Plossl and 28mm RKE eyepieces, the Antares Reducer produced short arcs of dashed star images in the outer field of view of the eyepieces in a Celestron C5 starting from about two thirds out from center. Returned for the Celestron f6.3 Focal reducer which shows a relatively flat field and pleasantly tight star images.
