For sale 6 inch f8 homebuilt dob of unusual appearance.

Discovery 6 inch primary (regular optical glass 1" thick), Discovery 1.3 inch secondary only a few months old. Optics are pristine and views as expected from Discovery--very nice.

If desired, buyer could upgrade the primary with a larger mirror (7" f5-f7 or 8" f5-f6) with very little modification to scope required since scope was designed to hold an 8" primary.

Primary collimation adjustments in front rather than behind mirror. Truss poles partially collapse for easier transportation or can be removed for even more compact storage. Both secondary and primary mirror mounts are homemade. Secondary mount is supported by a strong but thin curved support. Focuser is Orion's new 1 1/4" fine focus adapter which works well. Whole scope weighs around 25 pounds including five pound counter weight.

Only missing item is a finder. Buyer could mount a Rigel on upper tube ring or a laser pointer on lower assembly (which is what I intended to do). Asking around $340 plus shipping.

I need to sell to help fund a deposit on a longtime desired refractor.

Thanks for looking.
