Re: Hubble Palette and Star Colors

I was messing with some data and had an additional question if you do not mind. How does Startools react when you load the SII-Ha-OIII straight away and start stretching? Most people want to stretch OIII and SII more such that Ha does not dominate the image. I tried to stretch and process them indep...

Hubble Palette and Star Colors

I had a quick question, which is probably trivial for the more experienced people. My main problem is that I did not come to Startools with any other software under my belt.

Processing red halos when using camera lens

Camera lenses are designed to be at prime focus for the green light the way I understand it, which results in red and blue being a little out of focus. Especially for modded cameras, you end up with red halos due to the out-of-focus red channel. So if you're not using a narrowband filter and end up ...
