This is the best telescope I have ever owned or used, period. And I've owned things running from 3" apo's to a 14.5" dob.
This is a 10" f/8 dob, built by me, painted navy blue and geared for planetary viewing. Secondary is 1.5" (15% obstruction). Primary is by Telescopics, secondary is UO, as is the secondary holder and spider. Primary mirror cell is UO also, back of the tube is open so air flows freely around the mirror for rapid cool-down. Focuser is all-metal UO r&p focuser. Tube is heavy .3" thick sonotube, very thick and stiff, box is plywood.
Absolutely the best planetary images I have ever seen. With this focal ratio, you have practically no coma and little need for barlows, fancy-correcting eyepieces or other multi-element light-impeding optical leverage. Asking $1450 and you need to come here and get it because I can't even get it into my car! Selling to fund a bigger scope project and it isn't easy to sell this baby so email before I change my mind!
