This is a follow up to my question about processing Ha data in galaxies. My question was stimulated by something Ivo said a while back: "There are a number of ways to incorporate the Ha data into your processing. Which is just as well, as much depends on the object (ex. galaxy with just a few HII ar...

These days I’ve been concentrating on galaxies. From time to time, I have separate files for Ha. My question is, what is the best method in StarTools for bringing out the concentrated knots of Ha in galaxies? I’m aware of these two postings by Ivo on combining Ha with RGB, but I’m wondering if there...

I’m steadily getting better at using StarTools, although there is a lot more to learn! Here is a example of the power of this program. I’ll start with an image of the interacting galaxies NGC 1531 and NGC 1532. This image was processed by the professionals at the Gemini Observatories and was the APO...

Now that 1.4 is working perfectly on my Mac, I’m making a concerted effort to relearn StarTools. I’m interested in interacting galaxies and have been concentrating on Hubble data. Here is an exercise with the “Grasshopper” (UGC 4881). This image was captured in 2001 by the ACS camera, which uses two...

I just want to say again how pleased I am that StarTools 1.4 is now working in my MacOS. Except for certain things, goodbye Photoshop, goodbye PixInsight.

I recently downloaded the most recent version of StarTools 1.4 and was delighted to discover that it runs properly in the Mac OS. Ivo, thank you! About a year ago I re-entered astronomy after a 30 year absence. When I discovered the limitations of the 32 bit version of StarTools, I took a tour throu...

Ivo,

Thanks for your comments. Your postings are always thoughtful and I really appreciate all the hard work you do for StarTools.

Hi ancienteyes, Thanks for your comment and your willingness to help a newcomer. In the case of a world-wide network of remote controlled telescopes, you don’t need to compromise on dark skies, excellence of equipment, variety of telescopes, suitability of the weather or even choice of hemispheres. ...

I was an earnest amateur astronomer 30 years ago and just returned to the hobby. Everything about it is better. This is my first astro photograph. As a means of learning the ins and outs of StarTools, I decided to make it difficult. The subject, NGC7184, is relatively small and faint. I used just fo...
