Serial no. 2.102. 1/7.6 wave p.t.v. at 555nm, Strehl 93.6% (with optician's certificate). OTA weight: 34 lbs.

Includes the following:
- Intes 10x50 finder and bracket
- Van Slyke Monster-2 focuser (not the one shown in photo)
- Base plate has four additional 1/4-20 threads along centerline
- Custom Scopeguard case
- Astro-Zap flexible dew shield for 9.25" SCT
- Kendrick dew heater ONLY (item 2012) (no controller)

It holds collimation perfectly, shows textbook airy disk, has 26% central obstruction. There is a small 1/4" scratch in the tube's paint job. Monster-2 focuser has a small gouge in the drawtube (does not affect operation). I installed a brass setscrew to securely lock the focuser without any gouging. Focus travel is 0.9 inch. You will probably need a short drawtube extension to bring eyepieces to focus, even with a 2" diagonal. Astro-Physics part ADA202 works well for this purpose (part of BARCON, not included). BORG drawtube parts also work well. There is ample backfocus for CCD, video, webcam, or film photography.

This OTA was delivered new from ITE, who imported it from INTES Plus, in March 2002. Replacement cost is over $5000.00, your cost is - well, you convince me what your cost should be. Ask me for a link to my website, which has more info and photos. You can pickup or I'll deliver in the Los Angeles area.

Shipping info, for your information:
OTA + Scopeguard case: 65 lbs. approx. 36" x 22" x 24"
Finder+bracket, dew shield, heater: 3 lbs. approx. 14" x 10" x 10"
(FedEx Home Delivery rate approx. $59.00 total)
