Re: WIP, my first M101, featuring Holmberg IV

The SN is the cherry-on-top for your visit of M101. :thumbsup: It's an area that's definitely worth revisiting if you ever end up going higher magnification and narrower fields.

Re: Wrong Scale using Mask (?) Module

Now fixed (still alpha though).

Re: StarTools 1.9 preview

I just released a new alpha with more control over the de-ringing parameters (as well as a substantial improvement to processing speed when using intra-iteration resampling). I think you have all helped me realise that there are just too many ways datasets can be compromised that require more hands-...

Re: First time out

Further to the excellent advice here, one of the reasons why you would want to avoid live stacking (if you can), is that the live stacker can only use stats from whatever has been coming in. A post-acquisition stacker can gather stats on all frames that have come in, in its entirety, and make decisi...

Re: Supernova SN2023ixf in M 101 (UMa)

Yes, I was using SV Decon (Syntetic Iterations up to 12x, Syntetic PSF Radius up to 1.8 pixel). Definitely try giving SV Decon some samples, so that SV Decon can correct the shape of your stars (and detail) depending on the local (fancy word "spatially variant"/"SV") distortion. It was made for exa...

This is awesome! It has to be such a satisfying feeling to know even more of what you are producing is personally handcrafted, real optics, real detail, real everything. :bow-yellow:

Re: WIP, my first M101, featuring Holmberg IV

IMHO, as long as you disclose what you did, I think adding the supernova using a mask is absolutely acceptable (and, yes, lighten is probably the way to go :thumbsup:). From a documentary point of view, you are not "inventing detail" in the object as it is today, though you are "inventing detail" in...

Re: How to de-ring in v1.9 alpha vs v1.8

As for the lum filter for the ASI2600MC, it supposedly has a UV-IR window already. Ah, okay. I have just found that in the manual as well. I'm not sure why the spectral response on the website shows clear QE responses in the IR part of the spectrum? Perhaps it's with the window removed. :think: 202...

Re: Supernova SN2023ixf in M 101 (UMa)

Very nice and holds up well at higher resolutions too! Did you try to use SV Decon? It may help a little with the star shapes being not quite round (nitpicking here). You may wish to bin about 71% (or even 50%) to help with signal quality before you do that though (I think the dataset is a little ov...

Re: Wrong Scale using Mask (?) Module

Thank you!
Confirmed and fixed for next release (hopefully first beta! :D)
