Ive been thinking of buying a refractor recently so this thread is of some interest to me, Ive owned the older FSQ once upon a time and really enjoyed imaging with it. the only reason I sold it was that I wanted to image at longer local lengths and knew a better mount would make life easier, turned out my EQ8 was not up to the job. Anyway not having the funds nox for an FSQ Ive been looking at various reviews on a number of refractors, I narrowed it down to either the WO 130, Esprit 100 or 120, I do fancy the longer focal length of the WO130 & SW120. Looking at various astro images on line and Rays pelican shot above, The Esprit's FOV looks to be well corrected up to APS which would be fine for me. Would like to see is individual subs though RGB so I can determine if there is any bloat in the blue channel, narrowband only tells 1/2 the story.
