If as you say, everything is a fuzzy blob, perhaps you are over exposing when focusing, try lowering the gain a touch

On the mount in the observatory ready to go.

I have an 8" RC and didn't bother measuring back focus, I had no clue where it was for my setup I just went with the tried and tested 'try it and see' method

I have passed a message on to Barry at beacon hill for you. He is pretty much retired now but I do know he still does the mounts.

Before I automated things that's exactly how I used to do it

Very interesting thread, my QHY9 defiantly blows away from the heatsink.....quality control!!!! Anyway I have just flipped the fan around and will bang off some darks tonight.

My QHY9 draws warm air from the heatsink to the outside air

At least it wasn't your homework.

I had a go with it and it couldn't find my filter wheel (ascom) so uninstalled it

Im sticking with the version i have now, it works for me and i have no need to upgrade. if they bring out a radical new version i will bite the bullet ( but i cant think what that upgrade would be.

I know. It happens to me all the time

I wonder if you accidentally left a Lum file ticked while stacking say the Red channel Kappa Sig would see the extra pixels as outliers and remove them?....asking for a friend.

spot on

I have the EQ8 and run it with encoders disabled.....no problems with SGP.

I stepped into the garden at 3.30 Sunday morning and noticed Orion just rising, looked a bit higher and spotted M45, and for the first time could make it out without averted vision. The seeing must have been exceptional just then because not only could i see it directly, i could distinguish separation between the stars.
