I typically shoot at native resolution with my ASI2600MC for any single target. Recently, I’ve started collecting data for my first attempt at a mosaic, a two-panel spread over the Eastern Veil Nebula. With frames from my camera being about 6000×4000 pixels, and needing to collect two panels’ worth of… Continue Reading... "OSC binning in PixInsight"
I’ve been struggling for some time now to find a decent method to fix the brightest stars in my images. Since some stars are so much brighter than the deep space objects I am imaging, they become saturated due to the limited well depth of cameras. This means that information… Continue Reading...

When I started processing astronomical images, I went with the common open source tools Siril and GIMP. Siril worked very well for calibration, registration, integration, and some basic post-processing. I would use GIMP to finish images as best as I could figure out. This combination couldn’t give me everything that… Continue Reading... "New PixInsight Tools"
Depending on where a target is, I can have terrible gradients and mottled backgrounds in my images due to sky and local light pollution. I struggle each time to try to salvage bad images when simple background elimination doesn’t work well enough. Here, I’d like to outline a new idea… Continue Reading...

With nothing else to do with the endless cloudy skies, most of my astronomy has lately consisted of looking at other peoples’ images. My favorite part of this hobby is the creativity you can use while post processing your images. Some people prefer the blue-orange of the Hubble palette, others… Continue Reading...

I’ve discovered a fantastic new feature in Siril: you can now have it apply background extraction per frame in a sequence. Since the sky gradient can be quite different between sub frames in a project, especially when tracked all throughout the sky over multiple nights, stacking all of the frames… Continue Reading...

I found a really slick trick to reduce stars in an image using GIMP. It’s really simple and works amazingly well. Many of my images are absolutely loaded with stars, especially most nebulae which live in the galactic plane. After stretching, sharpening, and other processes, these stars can be quite… Continue Reading... "Star Reduction in GIMP"
I was always super confused when working with color SER files in Siril. In particular, the program always says you can “debayer them on the fly,” but I could never figure out how to do that. The files are definitely beneficial when doing lunar or planetary work, as they are… Continue Reading... "Working with SER files in Siril"
I’ve been having quite the time figuring out how to properly calibrate the images from my big ass Newtonian. I think I might be getting somewhere! The first key was taking proper flats, which I will do a separate post on soon. Along with flats, you also need bias frames.… Continue Reading... "Preprocessing with Siril"
I started my first multi-night project in Siril. It was a little unintuitive on how to do this. First, you’ll want to create sequences for the data from each night, and then preprocess the files. Make sure these sequences have the same name. However, you want to index the files… Continue Reading... "Combining sequences in Siril"
