Schmidt Cassegrain Telescope (SCT) Modification

Here we show step by step how to make 5 upgrades to a Celestron C11 SCT optical tube which include: 1. Adding nylon screws to the baffle tubes to try and reduce mirror shift 2. Adding internal fans with deflection plates to create a laminar flow acros the face of the primary mirror 3. Adding a temperature sensor to the backside of the mirror 4. Replacing the stock grease with a much better high temp low vapor pressure grease 5. Flocking the inside of the optical tube At the end of the video we discuss the performance of each improvement after a year of testing and share Dave's latest astro-image of the Orion Nebula taken with the improved telescope This is the companion video to two videos posted previously: 1.
