I am looking for a dob. Sonotube prefered but will consider truss as well. The ideal would be a 12.5 f/5-f/6. Optics must be in excellent condition - I can fix just about anything else. Something like a discovery would be nice. I would also consider one of the celestron 11" or even a coulter. If you have something that might fit the bill please let me know. Cosmetics are unimportant(however they may affect the price). I am willing to drive a little ways to get this as well. Any offers would be appreciated.
