Best improvements in performance

Well, I have a few -

These are my biggest "bang for buck" improvements -

1. Observing chair (homebuilt)
2. Rigel quickfinder
3. Replaced slow-mo knobs with nice ones from focusknobs.
4. Lasermate deluxe collimator - mainly because it makes collimation such a breeze as compared to using a chesire.

Best improvement I ever experienced was discovering that the secondary mirror in my GS 10 inch F5 DOB was pinched. After taking care of the problem, (basically just removing and reinstalling the mirror without foam trapped behind) the astigmatism which had plagued the scope disappeared.

Now the scope gives nice sharp images.
