PlaneWave 12.5 inch CDK Optical Tube Assembly

This is a one year old Planewave 12.5 inch CDK Optical Tube Assembly. The PlaneWave Instruments CDK12.5 is a 12.5 inch (0.32 m) f/8 Corrected Dall-Kirkham Astrograph telescope. The telescope has a closed carbon fiber tube, with 3 cooling fans ejecting air from the back of the telescope. The CDK12.5 covers a 52 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 46 lbs and comes with the large capacity 2.75 inch Hedrick focuser. The CDK12.5 comes with the standard accessories (wooden crate, 2.75 to 2 inch adapter, Ronchi Spacer and Ocular, OTA cover, Instructions, and 12VDC power supply). Additional accessories include:

1. EFA Kit

2. Delta T Heater System

3. Piggy Back 12.5 Dovetail

4. Finder Mounting Bracket

5. Visual Adapter

The optical tube is in excellent condition - no marks (housed in observatory). The optics are relatively clean and provide excellent images, if you want really clean optics you can send back to Planewave for mirror cleaning- bottom-line, if you shine a bright light the mirrors will show some dust.

I have used this CDK12.5 primarily for CCD imaging within my Observatory for about a 1 year. I did early comparisons with my 14.5 RCOS and it performed very well. I have included some images (others can be provided on request)? there are better ones on the web from others who are better imagers, pictures were taken with a FLI ML8300 CCD camera. I would not be selling if I did not already have on order a larger 17CDK. I plan to use the funds to purchase a larger scope - so this beauty has to
