This is the video of my Workshop held at CEDIC 2019 in Linz.

It shows a way to compose narrow band data of emission nebulae into a near true color image.

In the February 2018 issue of the magazine Nuovo Orione, an article written by Luigi Fontana appeared about the acquisition and processing of images acquired with two different setups.

In the article, in a sidebar, I explained how to apply the composition technique with PixInsight.

The Astro Imaging Channel: Challenge nr 1

Wed, 17 Jun 2015 20:56:08 +0000

On Monday June 22nd 2015 The Astroimaging Channel proposed an image processing challenge (read here) based on a set of RGB images of the Markarian chain.

This was the challenge:

1. Gradient Removal while preserving star color.
A few months back, I wanted to try imaging my blue channel high up in the sky. It didn’t work out as planned and I have a terrible gradient through the image. I’ve been able to get rid of the gradient, but it leaves a bad color cast through my stars. The challenge is to remove the gradient and preserve the star color.
