One of the best ways I have seen the process described was on this post in the Cloudy Nights forum: РІР‚СљDark frames will subtract the dark current accumulated in each pixel well from the total well contents. This principle applies to all cameras used for astrophotography, whether itРІР‚в„ўs a DSLR or a cooled dedicated astronomy camera.Р”В¬alibration frames used in astrophotography Applying all of the recommend calibration frames to your deep-sky images can improve the SNR (signal-to-noise ratio) of your images and overall image quality. The stacking process alone (light frames) removes random camera noise, but applying dark frames takes it one step further.

Software like DeepSkyStacker, Astro Pixel Processor, and PixInsight will subtract the noise pattern from your final astro image as best as possible. An average of dark frames can be subtracted from your final image, as the fixed-pattern noise and amp glow will be isolated in a master dark. The process of subtracting dark frames can help reduce this effect.Р”Вark frame subtraction allows you to minimize the amount of noise in your long exposure images that were created by the sensor. The circuitry in your digital camera produces unwanted signal that can degrade the quality of your image. If you expose an image for a period of time with the lens cap on, only noise is recorded without any signal. Signal is the actual light emitted from an object in space such as a nebula or galaxy, while noise is the unwanted electronic variation in color and brightness produced by the camera sensor.Р”В«asically, a dark frame only captures the random electronic thermal noise from your camera sensor. The sky will be much smoother, with an improved signal-to-noise ratio. The difference between an image that has subtracted dark frames and one that hasnРІР‚в„ўt can be significant. ItРІР‚в„ўs simply a matter of loading the files into the software using the correct settings, and it will apply them your image data appropriately. To utilize the power of dark frames in your images, youРІР‚в„ўll need to apply these support files to your final image using software like DeepSkyStacker. When used correctly, dark frames reduce the amount of noise in your final astrophotography image.

Much like collecting flat frames and bias frames, they are a critical stage of the acquisition process if youРІР‚в„ўre looking to improve the quality of your images.

Learning how to capture proper dark frames is something you must learn early on when you dive into the hobby of deep-sky astrophotography. If youРІР‚в„ўre shooting images using a DSLR camera, youРІР‚в„ўll likely need to apply dark calibration frames to each and every one of your astrophotography image projects. This one of the many reasons amateur astrophotographers like myself capture several exposures and stack them together. Beginners are often faced with the realization that their single image frame cannot be processed or stretched without pulling these unwanted qualities forward. Thermal camera noise shows up as unwanted artifacts and grain that reduce the quality and aesthetics of your images. As an example, the ambient temperature of a cold winter night in my backyard can be -5 degrees, but the camera sensor in my DSLR will warm up to 15 degrees Celsius or more. When shooting long exposure astrophotography images with a DSLR camera you can expect the internal sensor to become quite warm. If youРІР‚в„ўre completely new to deep sky astrophotography, have a look at my top tips for beginners.Р”В®ach one of these images used dark frames for an improved SNR How to take dark frames for astrophotography

You will benefit from an improved signal-to-noise ratio, which means a higher quality image with lots of detail.Р”Р‡ortunately, learning how to capture successful dark frames is actually quite easy. IРІР‚в„ўve been photographing objects in space using a camera and telescope for many years, and dark frame subtraction continues to be an important part of my acquisition process today.Р”В®ssentially, applying dark frames to your final astrophotography image will reduce the amount of noise in your image. How to Take Dark Frames for AstrophotographyР”В¬apturing dark frames is an essential part of the deep sky astrophotography process when using a DSLR camera.
