I might try that with the AD8, quick and cheap. My planetary attempts have been so sloppy this season and Mars is coming to my time frame. Nice work. Hope you get the other issue resolved quickly, always something lol
dude ... excellent ideea... will do that to my scope before I even install it :) C11 ... feel for you.... there's always something going south.... ah well... keep it up and keep the family happy ;)
I've got vents and fans installed in the vents to move the air. It doesn't stop the tube from cooling off much faster than the optics. The insulation helped at lot.
The reason your seeing goes bad for a few hours a short while after sunset is because the earths crust holds heat longer than the air. The air has far less mass so what happens at sunset is there is a small window of good seeing opportunity. As the air slowly starts to cool faster than the earths crust, the crust temperature can no longer keep up with the change in the air temperatures drop. As a result, the heat radiates upward into the atmosphere, causing eddies to form for the next few hours until the earths crust can reach a reasonable enough delta for the seeing to settle down again. This is the real reason you are having this experience. It's more likely a coincidence that the insulation appeared to work.
What you can do to verify with certainly is defocus the fresnel pattern using a bright star. If you defocus 5 to 10 rings you will most likely see a heat spike or plume eminating from the central light baffle. Even with insulation it won’t stop this from occurring.
@@DeepSpaceDad I think it’s good you made the efforts to test this for yourself. If you want more certainty, then examining the heat plumes will confirm if the insulation is actually working. I have a friend who images planets with a C14 who has strong deltas. He said even with the insulation the plumes remained and thus, hindered the contrast.
Great so see the quality enhanced, I'll definitely try this on my own scope 😊
Hey I just replied to your question on Facebook too haha. Yeah it definitely helped.

Right?! Lol if you watch the short I just posted the focuser is loose! So that's an easy fix.

C11 ...
feel for you.... there's always something going south....
ah well... keep it up and keep the family happy ;)
Turned out it was the focuser coming loose like I suspected. Should be an easy fix tonight
@@DeepSpaceDad glad to hear it, you'll be the first person to contact whenever I hit a rock on my journey to tame the beast :)
Your little boy is cute. I like your insulation idea. My Celestron 14” Edge HD has a built in vent to help air temperature equalize. What do you think

Cool video!

It's both.

Are you saying that insulating my scope did not, in fact, improve the consistency of the performance of my telescope throughout the night?

I spent plenty of time out of focus both insulated and uninsulated and the internal thermals are definitely better with the insulation.
