Hi
Finally got to test my new Qguider cam some more.
All except the last one were shot with a 2.8x barlow. Last was without the barlow.
Qguider monochrome camera. raw fits images stacked and processed with flats in Registax
10 inch f5.6 newtonian. Unguided. No filters used. The last image required exposures to be 2 milliseconds long to avoid overexposure. Software allows exp. from 1 millisecond to 5 seconds, or one can manually enter a time up to several minutes long, though noise swamps things over a minute long.
Though the qguider is mainly intended as a guide cam it might make a cost effective lunar planetary imager. Its only $300 for a monochrome 1280 x 1024 cam. Peak QE is just over 50%. It would have to be cooled to do serious DSO imaging.
Seeing for these images fairly poor. I could see the moon "boiling" when viewing live images
