I have decided to end my astrophotography hobby.  I am selling the three elements of my setup separately (Planewave CDK 12.5, Astro-physics AP900 and SBIG 11000m/FW8).


This ad is for the telescope.  It was purchased new in 2008 and it includes the following:

Planewave CDK 12.5, 2.75" Hedrick focuser, 2.75" to 2" eyepiece adapter, primary to secondary spacer tool, Ronchi ocular eyepiece, Electronic Focuser Adapter kit, adapter from 2.75" Hedrick focuser to 2.7" Astro-Physics accessory thread and shipping crate.


The asking price is $8500 (I paid $10,800).  Buyer pays shipping from zipcode 03063 in Nashua, NH.  The original shipping document reported a crated weight of 163 lbs.

This has proven to be an excellent telescope for the type of seeing we have in New Hampshire and it has been a joy to use. It has always resided in my garage when it was not rolled onto my driveway for imaging. The rigid focuser and temperature stable optical design were well matched for my relatively heavy camera.


My most recent check of the collimation in aug-2017 yielded this ccdinspector result. It is slightly off to one side, but the star sizes only range from 2.1 to 3.1 arc seconds from a single 200 second luminance image. With a little work the whole image would be around 2.2 arc seconds.

Here is my last image of M27 from that same timeframe.
