- Now, I know that flat frames are as important as taking dark frames. The uneven field illumination and vignetting in my deep sky images were a real pain to correct in post-processing. Like many aspects of deep-sky astrophotography, your method of taking flat frames will vary depending on the equipment you use. The method I have described for ...

- Dark Frames: 20-40; Flat Frames: 50-100; Dark Flat Frames: 20-40; In time, you will find the numbers that work best for your camera. How Do You Use Calibration Frames? Calibration frames are used in software for image stacking to calibrate the light frames prior to stacking them into a single image.

- Essentially, applying dark frames to your final astrophotography image will reduce the amount of noise in your image. You will benefit from an improved signal-to-noise ratio, which means a higher quality image with lots of detail. Fortunately, learning how to capture successful dark frames is actually quite easy.

- FLATS AND DARKS DARKS Another way to reduce noise significantly is to create a dark frame. A dark frame is a picture that you take when the lens of the camera has the cap on. No light gets in but the noise is still there. You in effect take a picture of the noise. You then use computer software to subtract the noise layer from your photos.

- In DeepSkyStacker, select the calibration files along with the image data files by clicking, in turn, Open Picture Files > Dark Files; Flat Files; Dark Flat Files; and finally Offset/Bias Files. Of course, if you are only applying dark frames, you can ignore the other calibration sets.

- If your camera can reliably shoot bias frames, darks+bias+flats suffices. If not (e.g., the ASI 1600), then darks+dark flat+flats. Put another way, you only need dark flats if your camera can't shoot bias; if that's the case, bias frames will actively hurt image quality so …

- Dark Flats? - posted in Beginning Deep Sky Imaging: Good day, everybody! Being that I am still just getting my feet wet in astrophotography, I had a quick question about Dark Flat calibration frames. I see a lot of folks saying its not necessary to take them as long as you have Bias Cal. Frames, but I also saw some people say that the Dark Flats were better for an ASI …

- If your flats are longer than 3 seconds (not unusual in narrowband or if your flat source is too dim) you will probably start seeing those things and it's time for dark flats. This regardless of sensor tech (CCD or CMOS), although on CCDs read noise is higher so simple bias frames typically work for longer flats than CMOS.
