You should know the basics of deep sky astrophotography and how to acquire multiple sub-exposures of an object through your telescope.

What you’ll learn

Using PixInsight to process deep sky galaxy images

Calibrating and integrating sub-exposures with WeightedBatchPreprocessing

Noise reduction with MURE Denoise and TGVD

Sharpening with Deconvolution and Photoshop’s Smart Sharpening

Automatic Background Extraction

Color combination and calibration

Creating effective luminance and star masks

Aesthetic tweaking of your final image


We only cover the processing of your images, not how to collect them.

You’ll need a copy of PixInsight (they have a free trial) if you’d like to follow along hands-on.

The sample data used in the course requires at least 6GB of hard drive space.


PixInsight is a powerful tool, but with a steep learning curve. If you’re ready to take your astrophotography to the next level, this course will de-mystify PixInsight and unleash its potential for you. Even if you’re an experienced PixInsight user, I think you’ll find some tips, tricks, and scripts you may not have encountered before.

We’ll walk through the processing of the galaxy M61, a distant, challeg target that includes an image of a recent supernova! As we go, we’ll cover:

Installing my PixInsight process icons and third-party scripts to simplify things

Identifying and discarding bad sub-frames with the Blink process

Calibrating your frames across multiple nights using the WeightedBatchPreprocessing script

Weighted stacking with WeightedBatchPreprocessing

Linear noise reduction with MURE Denoise

Cropping your integrated images

Creating luminance, range, and star masks

Sharpening your image with deconvolution

Background extraction

Color combination, luminance integration, and photometric color correction

Stretching into non-linear space while preserving star colors

Nonlinear noise reduction with TGVD Denoise

Aesthetic tweaking with RGB and saturation curves

Shrinking and re-shaping stars with MorphologicalTransform

Annotating your images

Final tweaks in Photoshop

This walkthrough uses monochrome data collected over 3 nights using luminance, red, green, and blue color filters. But many of these techniques will be the same if you’re using a color camera as well.

Don’t let PixInsight’s unusual user interface and complexity scare you off – it’s worth learning, and can really take your images to the next level.

Who this course is for:

Astrophotographers intimidated by PixInsight’s complexity and learning curve

Experienced PixInsight users looking for some new tips and tricks
