- Dark frames – that is, frames taken with the same settings as your main image frames but with the lens cap on – can help you to deal with this problem in astrophotography. It is important that dark frames should match the parameters used for capturing your deep-sky images with regard to exposure length, ISO number (where appropriate) and temperature.

- Why Do You Need Dark Frames In Astrophotography? As noted above, dark frames are used to reduce noise in astrophotography. Because there is significant heat being built up by the camera sensor during long exposures of night sky objects, it’s important to take darks that can be subtracted from your light shots later on.

- How to take dark frames Dark frames are obtained by covering the telescope and acquiring frames using the same camera settings, exposure time, temperature, etc. that the frames to be calibrated. If during the night the temperature does not change significantly, I just take a series of 40 to 60 dark frames.

- Because you need to take the dark frames at the very same temperature of the light frames (or within 1-2 ºC from it), ideally, you want to have a cooled camera for astrophotography. With a cooled camera, you can efficiently control the sensor temperature and even cool it down some 20-30 ºC below ambient temperature.

- Dark Frames. A dark frame is like a bias frame in that it's an image taken with no light falling on the image sensor, but dark frames need to be the same length as your light frames. In other words, if you take several 3-minute exposures on your target, you’ll want to calibrate them using a 3-minute master dark frame, which you'll subtract from the image.
