I don't really want to look as they're really, really impressive ;( My 10 minutes test sub got absolutely no hint of Oiii

There is a very bright star in witches broom in my 3/4 panel mosaic. It looks like there's a small halo around it, but I've seen worse. Only 40x120seconds though. I might try ic59/63 if I get a chance, but not tonight as forecast has changed from green to red

I can post some two minutes subs. Also some longer test subs if you want a look see? I'm most surprised by lack of gradients, especially previous night when moon was on holiday. Bit more gradient last night but barely noticeable

Svbony sv220 2" Bare in mind while I think it's great, I don't have experience with any other filters except my svbony UV/ir cut. I'm going to get a 2" UV/ir cut I think

so i took my image of ngc 6992 from previous night and stacked it with the two over lapping panels from above and....its alright. no splitting Ha/Oiii or anything clever.

ty. this filter seems pretty amazing. this is the first time i've seen a gradient in my dnb stacks and barely at that. hopefully my time dealing with huge gradients is over

that's my plan i didn't crop any of the panels before gradient (what gradient? dnb filter ftw) removal for this quick test so im sure there's plenty of edge issues. once i get my missing panel back and some more time on the other 3 ill put more effort into the post processing also for panel joins...i just exported each panel as a tiff, selected all 3 then right mouse click send to microsoft ice, click next, click next, click export

not sure where the missing panel went i did get nina and phd2 freezing. thought i set it back to carry on but..... just a quick stretch test (in sunlight so might be very over done). 40x120sec subs per panel hopefully i can fill in the missing panel gap tonight seems to look ok. if anyone in a semi dark place have a quick zoomin/look please lol?

I did look around and it is a decent deal After ordering I saw the holder on eBay for £18 if anyone needs

Directly from svbonys site. I did ask if I could buy a single filter holder instead of a 3 pack. Think it was £120 no extra charges took 9 days and brought clear skies and free stickers. £14 of that was "no extra import fees" I shouldn't have taken.

I had way worse on same target. Some of those edges weren't even visible with histogram view until after gradient removal. So I'd restart. Then find another. Had to crop so much didnt leave much left

I've heard people use thick shower caps. I think Cuiv used tape then I think got a 3d printed plate?

This is my plan for my reason detre, the horsehead nebula. Will also try hh in dnb too of course

I'm sure it's possible. On my list to learn

I think, after a better mount pixinsight is next on my list

You mean by eye? Another reason I should learn gimp layers. Small icons though

Yeah taking the data is the easy bit. I can stack RGB and dnb separate then extract stars and put back RGB ones only. But no guarantees they will line up exactly. Maybe close enough no one will notice, but that doesn't seem proper

I still like my veil 4 panel

Er, tbh lining them up with a different stack background. Pretty sure this is relatively straightforward in pixinsight, not so much in free tools. Probably another reason I should learn full manual stacking, alignment etc.

Ok so this is miles better than my attempt. You even got the bubble behind it too. Also don't think I've seen two bow waves off the front of the brain before. I can't even image one of those bow waves.

i said it first

i shall give it a try ty

I think I misjudged how straightforward RGB stars and dnb background would be, so I'm avoiding it for now I don't even want to imagine what RGB stars plus mono backgrounds would take. my RGB stars are hardly fantastic so I'm ok with narrowband ones for now at least.

ty no pixel math or anything. im quite happy with this, just need another 20 hours on it
