Fighting the noise in astrophotography
It is a well-known fact, that long exposures in astrophotography make the final image quality better. Specifically, the signal-to-noise ratio (SNR)…
Live stacking with SharpCap
Deep sky objects in the night sky are faint, very faint, extremely faint, or unbelievably faint. For visual observations we use telescopes with large…
Different times of astrophotography
Long time ago we have been doing astroimages with negative (or positive) film. We had one chance to take a long exposure photo. Then we have been…
Pixel scale and resolution
Is astrophotography pixel scale and resolution the same? Can we increase resolution just by making pixels smaller? In some cases we can, but quite…
CMOS gain settings part II
In the first part I made a little introduction on gain setting in CMOS camera and also presented simple comparison made with luminance filter. In…
CMOS gain settings part I
Once we start to image with CMOS cameras, then we need to deal with more settings than with CCD cameras. I described some of them before, but now I…
CMOS calibration challenge
After some time with deep sky imaging with CMOS cameras I need to say that calibration for this kind of imaging is even more important, than in CCD…
CMOS settings challenge
CMOS sensor based cameras are becoming more and more popular among both new astrophotographers but also among current CCD users. Many people in this…
To CMOS or not to CMOS
CMOS sensor based astronomy cameras are becoming more and more popular among astrophotography amateurs. What differs CMOS from CCD? Is this really…
