For sale a portable 6 to 8 inch dob in need of a primary mirror.

It has a Discovery 1.3 inch secondary only a few months old. Optic is pristine and views are as expected from a Discovery secondary--very nice.

Buyer will need to add a primary mirror (6" f5-f8, 7" f5-f7, or 8" f5-f6) with very little modification to scope required since scope was designed to hold an 8" primary and trusses are adjustable in length.

Primary collimation adjustments are in front rather than behind mirror--4 wing nuts. 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 without a primary or counterweight weighs around 17 pounds. Constructed from high quality oak plywood.

Also missing 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 $200 plus shipping or $150 plus shipping w/o Orion fine focus adapter.

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

Thanks for looking.
