Veil nebula

Ivo,

Thanks!

A link to the stack is below. This is ~2 hours, taken with an unmodified D5300 and an Optolong CLS-CCD filter, w/Flats and dark-flats, no bias, no darks.

Re: Mask Brush

Ivo, I just upgraded to 1.5.364, and had hoped that there would now be a real brush available in Mask Brush, but no joy. Lots of things I like about StarTools, but I do what I can to avoid masks. Consider the Western Veil, which I'm now processing. A lovely wisp of red/pinks and blues, incorporating...

Re: Light pollution- horse head nebula

Jaume, Kind of quiet around here... I was expecting more would jump in. Regarding DSS settings, that's always 'fun'. If you do a startools forum search on "DSS", you'll find a number of posts with settings advice (some of which seem to go back and forth a bit over time - and then, of course DSS chan...

Re: Light pollution- horse head nebula

Jaume, I took a second look at your images this morning. I can't do anything with them, but here's some things to think about, FWIW. The Vixen image looks to me like it's first problem is a stacking issue of some kind. That white moire doesn't look right to me - should be black, with just a small sp...

Re: Light pollution- horse head nebula

Jaume, Caveat: I just recently got help with a polluted image, so I'm no expert (but I did just process my own Flame/Horsehead, so I'll run with it :-) I looked at both your Mak and Vixen images, and took a run at them in StarTools. The Vixen one looks to me like there's a real problem back at DSS, ...

Re: Adjacent stars w/merged halos

Ivo, Thanks for the explanation of how Autodev is using ROI! I'd tried a number of different ROIs, but hadn't been able to achieve much more than differently-shaped halo blobs - or a too-sharp image with a much reduced star field. However... I ran across a post you made re: deconvolution where you m...

Adjacent stars w/merged halos

Hi! Richard's tip about using ROI (not always where you'd expect...) to influence Autodev's behavior has been most helpful to me, but there's one behavior that I can't seem to get control of. Wondering if anyone has found a way to beat this? Consider the case of two adjacent stars, where at least on...

Re: M27 - need a hand, please!

Richard, Ivo... Any thoughts on that ROI in Autodev? << If I keep at it, I think most of what you've done will sink in eventually :-), but the one step that's just a complete surprise is the effect of ROI in Autodev. The star you selected does indeed clean things up, but selecting others produces di...

Re: M27 - need a hand, please!

Richard, I updated to the latest version. That really was a very helpful video - I'll be referring back to that. Attached is a jpg of where I ended up after trying to replicate what you've done (first full run-through). There were a couple of things you wondered about during the video... The noise i...
