[QUOTE="JGobeil, post: 3175717, member: 24649"] Welcome to the club. The SW80ED is a fine scope at a very good price enjoyed by many of us. I wish you fun and success with it. I cannot comment on vignetting since I use a M43 camera but here is a bit of info on the focuser. When properly adjusted, it works beautifully: it is smooth and does not slip at all. The 2 button focuser is even better, allowing very precise adjustments. It is quite easy to take down but you need to be careful not to loose the small o-rings. Is is also easy to reverse the knobs to have the dual knobs on the left so that you can control the camera with your right hand while focusing with the left hand.

There seems to be a problem with the search function. The 3 URLs above should give you all the info you need. I also think you should consider flocking the inside of the focusing part of the scope (adapters, extension and focuser tube). It will substantially improve contrast and does not cost much. Good luck Jules [/QUOTE]
