All tutorials listed here are made for PixInsight.

Full Processing

Soon I’ll post here my full processing workflow. (September 2017)

Basic Processing Steps

Subframeselector – PixInsight

After a nightly session the first thing to do is to analyse the lights. This can be done visually or mathematically. Or both 😉 First of all I pre-sort the lights visually. But since I use an AutoGuider I can use almost every light frame. Only if there are air planes or satellites I’ll sort […]



Stacking in PixInsight

In PixInsight 1.8 the stacking process is really easy to handle. Very similar to DeepSkyStacker, but the result is much better. The image is overall sharper. The following settings and values I’ve collected during the last half year from various forum posts or tutorials. Currently I use only light-, dark- and… […]



Remove Tint in PixInsight

Images taken with the Astronomik CLS-CCD Filter have a very strong color tint. In my case the tint was cyan and now green with the modificated EOS 70D. Anyway, PixInsight offers many ways to remove such a tint from the stacked image. I’ll show here one possible process […]



Reduce Star Size in PixInsight

Reducing star size can helping highlight the main object like a Galaxy or a Nebula. PixInsight offers herefor a process: Morphological Transformation. Here are my current steps to reduce the star size in my images. StarMask Create a StarMask. I always use the default values here. […]



Special Tutorials

Comet Processing

To stack 41P comet I used for the first time PixInsight. Unfortunately (or fortunately?;-) DSS failed to select the comet on a single frame, so I switched to PI. Finally after several hours try & error and many tutorials I was able to manage the comet. See here the used processing steps:   Comet Processing […]



Comet Animation Tutorial

First, there are 2 possibilities for a comet animation: Static comet or static stars. I’ll show here both ways since they are very similar. Note: these are very quick processing ways. They are surely improveable 😉   Static comet Run BatchPreprocessing Open Process – CometAlignment with […]



Drizzle Integration Tutorial

After posting my recent M57 image on Astrobin, I received a feedback regarding Drizzle (thanks Marcus!). I never drizzled before since I thought it’s very complicated… It is not! Drizzle was originally developed for the NASA’s Hubble Deep Field observations. It provides a flexible […]
