4.5", 6", and 10" Newtonian astrographs.
2 ST80s; ED80; 3 CCD cameras; 5 EQ mounts: all polished, tuned, and modified.
The rule of telescope features: aperture; equatorial tracking; or low cost. Pick any two.

Quote:that looks like a great objective. get the 2in focuser since its a widefield and add an inexpensive ~35mm 70° eyepiece with the kit.

Quote:You bring up a great point. Maybe the best thing to do is find a excellent condition ED80 that only needs a focuser and a refinish? That will certainly save time and money. Not a bad idea you have there!obin

Not a bad idea you have there!obin I think you are on the right track, if you can afford it. Otherwise, maybe an Orion ST-80 rather than a Surplus shed objective. The barebones Orion is $120 and from what I have gathered, you probably get a better objective with the Orion. I put a 2 inch focuser on ST-80, looks good and while it is far from an 80mm apo, it's quite a usable scope. And airline portable. Jon
Quote:I'd say go with a used ED80, refinish the tube (powder coat is good, or epoxy then use a thin film stick-on of the school crest). Replace the focuser with a William-Optics, or if you're lucky buy an ED80 which already has the WO focuser.
