Playing with the gain and offset shooting darks now. Is there a way to modify that in Maxim without disconnectting the camera to access the ASCOM setup?

Dammit - you could have my QHY-9 almost new and certainly cheaper. I'm thinking of moving it on and going back to simple DSLR until I manage to build that observatory one day.

Good camera... just aren't using it enough.

Have fun with it!

From memory, on the exposure tab, open options and I think there is camera setting option.
I don't have maxim with me to check.

As for gain and offset. There was a post on here some time back on technical correct method of setting both. Craig stark also has a good write up on setting and forgetting these settings in the manual for nebulosity on his web site.

Marc, you can definetly change the Gain and Offset of the camera without having to disconnect it and change it back in the ASCOM properties.

On the exposure tab, click the Option > (right arrow) button and choose "Camera Settings". It should bring up the ASCOM dialog box with access to Gain and Offset sliders.

Thanks guys. That's where it was

@chris: don't you sell it. That would be a few step backwards. Persevere.

PS: as a quick note I'm using the ASCOM platform 6.0 with the same QHY9 drivers. No issues. So if you guys are thinking of upgrading it's all good. It's a straight update. No need to uninstall anything. Everything else works as well. PEMpro, Gemini, etc... even Neb2.

There is a cool feature that is in neb. You can append the UTC time to the filename. This way each file saved is unique. The problem with a sequential naming is that it's based on the last file saved. If you delete the files, then it starts again from 1. So if you happen to move the file again to another machine you'll end up overwritting the previous batch. Does Maxim have a facility where you can tell him what the name of the file will be based on time? Or maybe the name can be scripted. I have to look into the scripting. Looks like vbs?

PS: I added one 5min dark I did last night. A stack of 104 subs. Is this similar to what you guys are getting. -20c. Also added a snapshot of the ASCOM config for the cam. What's the fine tune boxes for? Also left the pedestal to 88. Not sure what it is and finally Motor Heating% !? What is that?

Got a PM back from Theo. The old QHY9 was fine. It was a faulty DC201 going full throttle all the time then cutting so no regulation. All or nothing. That's what caused the temp seesaw pattern. Always overshooting then cutting.
