Intes-Micro Alter M 503, 5", f/10 Maksutov-Cass OTA. In like-new condition and used only a few times. Smooth, seamless cream-colored tube with black accents and hardware. Fine optics; easily outperforms a Celestron 5 on the moon and planets, but(like all 5-inchers) the light grasp is limited. Comes complete with combined visual back/1.25" star diagonal, 7x35 finder, piggyback camera mounting bracket, tube carrying handle, a 16mm eyepiece, and a very nice padded carrying case. Rear threads on the scope will take standard Celestron and Meade accessories. I have far too many scopes, and this one is getting little use. $595 with FedEx ground shipment included anywhere in CONUS.
