Processing in Photoshop is very tedious, since the main problem is easily stretching the images to bring out faint details. With PS it requires many tiny increases using the curves and levels. With PixInsight – its a click of a button. I can now also easily remove light pollution and do proper deconvolution and noise […]

Aside from the light frames, which are the actual image data, there are also 4 types of calibration frames: Bias, Darks, Flats and Dark Flats. In order to remove vignetting and any uneven field illumination caused by dust or smudges found […]
