I am learning how to process images using a dedicated astronomy camera. I tried recording a Jupiter video in RAW format. RAW needs to be reconstructed to form color images in a process called debayering. When debayering, select the correct matrix for your camera (RGGB in an ASI 533). If your images still show the bayer (grid) pattern even after debayering, try other configurations such as GBRG or GRBG and see if it removes the artifact (the capture software may have recorded with the incorrect bayer configuration).
Planets are particularly difficult to image, especially if using a small 4-inch telescope. You need to image at very long focal lengths to magnify and zoom in to the planet and a large aperture to reveal finer details. To capture this image of Jupiter, I had to use an eyepiece to project an image on to an SPC900NC web camera’s sensor. Precise tracking is essential to keep the planet’s image in frame for more accurate registering and stacking of images.
