I just recently acquired one of these little 5" spotters and I must say that I am quite impressed with its performance.
When I received the scope I tested it inside with an artificial star 20' away. Star test was strange and collimation was way off. I tried to adjust one of the collimation screws when I noticed the secondary holder was very loose. I marked all reference points for reassembly and removed the corrector retaining ring and to my surprise there were no shims centering the corrector and had about a 3mm gap all around.
I removed the corrector, tightened the secondary holder, centered it with the best of my ability and replaced the retaining ring.
Star test later that night was significantly improved. I tweeked collimation again and now the images are superb.
Does anyone have experiences similar to mine? Did you make shims or just leave it be?
