I live here in Denver and purchased this equipment last year.  I did examine everything but I was never able to use it due to degenerative arthritis.

Everything is still in the original box, but the warranty is not transferable.

Astrophotography Equipment
Hypertuned Celestron CGE
I bought this used and immediately had it hypertuned by Deep Space Products due to some flexure I saw on one of the axes. I believe it's ready to go, but I've not used it for imaging. I've put in over $1500 for this mount. I'm only asking $1300, since it has sat unused and hasn't been tested (other than testing done by Deep Space Products).

Cables included
Minor crack in controller
I've been able to control this mount through the computer.

Celestron CPC 9.25-inch SCT
I am selling my Celestron CPC (9.25") Schmidt-Cassegrain telescope. It is in excellent condition (purchased in April, 2009). It originally sat within my observatory on a hill behind my home in Boulder. We've since relocated and it's simply not practical to use where I am now. It's being sold "as is" but is in great shape and worked fine the last time I used it. Along with the scope comes all of the documentation materials, cords, controller, and accessories. This includes a solar filter (that covers the entire aperture of the scope), a moon filter and a UV filter, a Televue Nagler eyepiece as well as a few other eyepieces and a Barlow. Also a power tank for remote viewing, and a DSLR camera adapter (pictured). All of these items together originally sold for well over $3000."

Price: $1700.00
