After learning some tricks and a bit more about image processing in general, I decided to take a stab at post-processing the Pacman nebula again. I attempted some better stacking techniques, and was able to reduce noise a bit from the start. The background extraction also went much better in… Continue Reading... "Retouching the Pacman"
Light softbox for taking flats
As I begin to take much longer exposures, the need for good flat images has become apparent. Dust specks on the camera lens and vignetting make a noticeable appearance once I start stretching images of extremely dim deep sky objects. To try to improve my flats, I purchased a studio… Continue Reading... "Light softbox for taking flats"
Siril workflow: preprocessing
I would like to record how I process my photos on here, mostly because there isn’t a whole lot of good documentation on Siril, and also because I will probably forget between imaging sessions. The first step to getting your light frames ready is also produce good calibration frames. Take… Continue Reading... "Siril workflow: preprocessing"
Applying stretching in Siril
I just learned how to actually apply stretching to the image in Siril, instead of only just previewing it in the preview windows. The Siril autostretch and asinh profiles are really nice, and tend to look better than what I can manually do in Gimp. First, have your stacked and… Continue Reading...
