Hmm, yes, I think I might back down to 90 sec subs. I looked back at my camera settings file for the darks and compared it to the lights. The darks were captured at 12.5C and the lights at 13.2C. To me with my limited experience that is not a huge difference. So I think that 120 sec subs are out, an...

Thank you, Robin. I totally agree.

With my image of NGC 7331 I have already proven that a 2 minute exposure is long enough to capture the faintest wisps of nebulosity -- so going longer isn't going to win me anything -- it is actually going to make things worse.

I employ dark frame subtraction. It's one of the best features of SC. I've read of subscribers compiling dark frame libraries on cloudy nights. It would be neat if SC could automatically switch to a new dark frame set whenever the sensor temperature changes. And if there is none readily available th...

Robin, The docs have precious little to say about sensor temperature. How often does SharpCap sample it? Can I set an alarm whenever it changes? If not, is it something I can do in script? I've decided to get really aggressive with this. The plan going forward is to watch sensor temperature like a h...

Here is my first attempt at imaging a galaxy. It is not perfect. My biggest mistake was reusing darks from the previous night when the ambient temperature was a couple degrees Fahrenheit cooler. I will never make that mistake again. I did not even check to see how different the sensor temperature wa...

I published a photo and description of my set up:

Thank you Robin and Dave for your compliments and encouragement. As a programmer, and jack-of-all-trades-but-master-of-none as my Dad would say, I agree that the key to sustained progress is pulling only one lever at a time and finding the one with the best risk-to-reward ratio. I agree that my came...

Robin, You might find this interesting. The last time I had some good weather was July 15th (12 days ago)! I had one last shot at capturing the Dumbbell. My motto is "do more with less" so I refuse to do guided astrophotography what with the cost of a guide scope and camera. Call me cheap....

Let me be more specific. When ZWO talks about "software" do they mean the software in SharpCap, or the Windows driver for the camera, or ZWO's firmware, or software incorporated in the sensor? I mean, software has its hands in the magic from beginning to end. From my perspective, SharpCap ...

Thank you for that great tutorial on Binning! The user manual for my ASI120MC says this under the heading named "Binning": The ASI120 camera supports software bin2 mode. You should use 10bit ADC. We recommend customer to use software binning if you don't care speed. Would you be kind enoug...
