Figure maybe $5000 for the OTA and $10,000 for a mounted scope. The mount will likely include modern electronics, perhaps Goto. Scroll near the bottom of the page. https://www.cloudynights.com/topic/5...estar-5/page-8 This is actually a diffraction-limited telephoto lens of long focal length. Can you replace the eyepiece with an T2 mount adapter? Thinking DOF here... -- teleportation kills |
