The best telescopes for astrophotography in 2021
January 26, 2022, 08:01, asked: S&M❤️??? Voyageurs du Monde
Common advice for beginners in astrophotography is to start with shorter focal length telescopes (600-800mm or even below, which give you a wider field of view) and a focal ratio of f/6 or lower (which helps you minimize exposure time)....

How to take Bias Frames for Astrophotography
January 21, 2022, 12:25, asked: Ryan Wightman
Personally, I have found that 20 flat frames are enough to create a useful master flat file for DeepSkyStacker to calibrate your image. Since these are so quick to capture, there is no harm in collecting 20 or more frames for each session....

The stacking process alone (light frames) removes random camera noise, but applying dark frames takes it one step further. ... This principle applies to all cameras used for astrophotography, whether it's a DSLR or a cooled dedicated astronomy camera....

The basics of flat frames
January 19, 2022, 01:15, asked: sirrahnais.com
Tracked wide-field images can look amazing with lenses from the 24-50mm range. And a zoom lens, anywhere from 100mm-300mm can work wonderfully with nebula and even large galaxies, like Andromeda (M31). Read our tutorial on how to use the free application Stellarium to choose the perfect focal length for your target!...

Calibration frames are used to calibrate against each other, as well as your light frames. A series of 25-50 of each calibration type (Bias or Flat Dark, Dark, and Flat) are typically taken then stacked together to end up with a single master image for each calibration type....
