My telescope mirror is 15lbs of Pyrex glass and retains too much
heat, so it has a custom TEC cooling system with fans, no big deal…(
https://maphilli14.webs.com/apps/blog/show/21342955-akule-s-cooling )
The original fans are in the blog entry from the original creation of Akule in 2011 and I upgraded them in 2015 to these fans.
Why cool the heavy mirror? It's #4 on my basics of high res planetary imaging - https://astromaphilli14.blogspot.com/p/seeing-collimation-and-focusing.html
"This
means having no heat plumes inside your OTA that cause locally
significant seeing issues. It may be as simple as setting your scope
outside a few hours before hand to help cool it. The larger your mirror
and the more closed your tube design the more help you'll need"
Here's
a video overview that might help explain how I pulled all this
together: Cooling unit, temp sensors and automated, unattended running
of the cooling unit.
