Re: Journal paper on spatially variant deconvolution?
More integration (oh noes!). This of course helps the base underlying linear data. Shorter subs to prevent saturation of cores, also thus linear state. Though I have used datasets with plenty of blown cores that SVD doesn't seem bothered with at all. Odd. That's great to hear, as that is usually a ...

Re: StarTools 1.9 Beta
It's indeed an interesting failure case for the de-ringing. I will have to do some troubleshooting to see what is happening here, but it appears the issue is some sort of extreme non-linear response in the troublesome stars. Similarly odd, is a complete lack of overexposure anywhere - it may be that...

Re: Journal paper on spatially variant deconvolution?
Thanks Ivo. I've been following along. I notice you mentioned that SVD is not really meant for "fixing" star shapes, and was wondering if you could expound on that for us. :?: I know we do have a spatial error slider (I'm not very practiced with it), and you've also mentioned before that adding ite...

Re: Journal paper on spatially variant deconvolution?
Thanks for the explanation, Ivo. Of course you saw it early. The deconvolution community must be pretty small. I don't think there's so much of a community , but you can't help but be exposed to other people's work when you're researching and tinkering. I don't really move in academic circles eithe...

StarTools 1.9 Beta
Hi all, The first 1.9 beta is now available. If you've been following along with the 1.9 preview thread, there should not be too many new surprises. But if you haven't, then please have a look at the CHANGELOG file, which should list the many improvements. Again, many thanks to hixx decay and Carles...

Re: M 8 - Lagoon Nebula
I love the visual spectrum version here! :thumbsup: The colors are spot-on IMO; the quintessential red/magenta is 100% expected from this H-II area, as it's a mixture of all emissions (not just pure red Ha). For example, there's Hb (blue at 1~/3rd intensity of Ha) and O-III in areas as well (teal), ...

Re: Journal paper on spatially variant deconvolution?
This link just popped up in the DSLR-DSO subforum of CN: https://arxiv.org/pdf/2212.02594v2.pdf Seems to be a science journal paper (which of course means it has a punny title) for a technique that will be employed on an upcoming NASA mission for a mini space telescope? I've just briefly skimmed th...

Re: Ngc6888 The Jellyfish Nebula
That's a respectable Jellyfish!
You will definitely want to start using deconvolution, particularly since 1.8 and 1.9 - there's a lot of (real) detail to bring out.
Do let me know how we can help.

Re: StarTools 1.9 preview
FYI, version 1.9.554.1 alpha will not open on my MacBook Pro with the M1 processor. I just tried on an MacBook Pro with M1 + latest macOS and was able to launch StarTools without issue... Please make sure to follow the unquarantining procedure (which was updated for macOS 13/Ventura). Do let me kno...

Re: StarTools 1.9 preview
Thank you all for all your help! I tracked problem down to a text-string bug regression that happened between 551 and 552.
The latest version 554.1 should work (hopefully) reliably now.
Any further issues, do let me know!
