Any tips for thermal management? so far I just open the dome shutters and door for several hours and run a big stand fan to facilitate circulation.

You would be surprised what you can fit. I had my 12.5" RCOS in mine for a while which I found a little scary. Peter Ward has fitted a 14.5" RCOS in his 2.3 Sirius dome before. Neither of these are small scopes.
If you are automating the shutters, just make sure the scope is parked and/or dome rotated into a safe position before shutter is closed. The lower shutter actuator enters the dome a fair way when closed. You could easily smash it through your corrector plate if not careful. When the shutter is open, its not a problem. Of course, if you are not automating the shutters, no need to worry about it as there is no actuator for manual operation. |
Thank you Jase, it is reassuring to know the Sirius 2.3 can accommodate 12.5 and indeed 14.5" RCOS fully geared. I am using automated rotator and shutters, will definitely look for the actuators when closing the lower shutter, something I never thought of. I will keep everyone updated. Cheers.
