I'm selling my somewhat abused Comet Catcher. I had to repair a couple of things:

1 The secondary mirror holder was lose on the stalk that supports it and the set screws (not the colimnation screws, those work fine) were stuck with industrial strength thread lock. So I JB welded the thing in place.

2 In messing with the scope when I first got it, I derailed the bearing in the focuser. I fixed that without too much trouble.

3 The little pinion gear in the focuser was made of plastic. It ruptured and I couldn't glue it. So I cut the brass pinion gear from an old focuser that I had and drilled a hole to mount it in place of the old gear. This works pretty well, but it isn't exactly centered on the shaft, so the force necessary to move the focuser isn't even throughout the focuser's travel. (It's not a huge deal, but I like to be frank).

I was going to use this as a super finder, but I aquired a diferent scope that will serve my purpose better. Opticaly, it is only so-so. (It does pretty well up to 100x)

I'd like to get $175 OBO for this scope, I'll pay for shipping. I accept money orders and pay pal (add 3%). The scope has a telrad base on it, but I can remove that if you want.


(I'll be off the air until monday Feb. 9, you can respond to the ad at any time, but I can't get back to you until then.)
