Apple Studio Works With StarTools

I recently upgraded my iMac to an Apple Studio, using an M1 Max processor. So far, no problems of any kind with StarTools.

Re: NGC 1955: An LMC Nebula Revealed

Hi Ivo, I was delighted to read your comments. Until now, I haven't been able to find any useful advice on how to achieve Rector's recommendations: balancing scientific accuracy with aesthetic appeal. In fact, among amateur imagers I've found zero interest in accurate documentation of the chemical c...

Re: NGC2359: Thor's Helmet Revealed

Hi Stefan, Please excuse this tardy reply. This approach to narrowband processing is experimental, so all my thoughts are subject to revision! I've attached an example of a palette comparison produced in PixInsight. These images are just simple channel combinations with temporary screen stretches--t...

Re: NGC2359: Thor's Helmet Revealed

Hi Mike in Rancho, As always, your thoughts are really interesting. I did not use the matrix. Instead I loaded the narrowband images into their appropriate channels in Compose, and did not modify the hues in the Color module. I did use Wipe--Hope that didn't introduce unanticipated hue shifts in the...

The Halos that Aren't

Ivo, I could use your help. I am frequently asked to explain why StarTools processes stars (especially fat stars) differently. In general, astro imagers are used to bloated stars with undifferentiated profiles. They believe that StarTools stars are either a processing error, or an inherent flaw in t...

Re: NGC 1291=A Really Faint Fuzzy

Mike, what excellent detective work! Sometimes, I wonder if I over-use Super Structure. It's a great tool, but maybe I'm accidentally nuking some really interesting things in the background. In fact, when my fellow members of Sonora Desert Astro Imagers look at StarTools pics, they often remark on t...
