Intes PLUS MK91 Maksutov-Cassegrain, A=228mm, F=3100mm, f/13.6

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 shown in photo)
- Base plate has four 1/4-20 threads tapped along centerline
- Custom Scopeguard case (photo at Scopeguard website)
- 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 or film photography.

If you are seriously interested, I will send a link to some more detailed information, and to some planetary images taken through this scope. Please do not waste my time with casual inquiries to send the links.

Asking $4000.00 for everything, will not split up any items. PayPal accepted from verified US members, from cash balance only (no credit card). Shipping extra, your choice of shipper, but there will be two packages:

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)
