This last pic in particular is really making me want to try this. At some point in distant future. Really nice image

Gonna have to read/research this a lot more, but it sounds like very good advice. When I keep my sky too dark it does look odd/oily as you say.

Some of his lectures are available on YouTube. Anyone who thinks they understand Mongolian nose trumpeting, doesn't

Your knowledge of this subject seems in Dire Straits.

Beyond my abilities so far, but I've watched your YouTube channel quite a lot over last couple of months and it's been a great help.

Well I failed with my idea of having two layers, one stretched by me as a guide layer but I'll try again later. I couldn't add two layers lol it kept replacing one. I think you're correct about the effect of cloning, I just wanted to try for myself and see. will update if I get it working in some way.

i was hoping to clone over some areas in the starless output from starnet++ before stretching that same file. if i clone after i stretch, i will be cloning more noise. at least that's how i see it in my head i just want to try it out. im not sure how i'd find which bit to use to clone over other bits, before stretching in gimp, without that changable view option siril has (linear, auto stretch histogram etc). Its possible i can copy the initial layer to a new layer, stretch one as a guide for me on the unstretched layer? then delete the guide/stretched layer?

I still want to try cloning over some areas in the starless output from starnet. Just to see any effect on how far I can stretch. Just need a way to see un stretched tiff in gimp without stretching it

to be honest, if i can maybe see some tilt in only very far corners, this is the perfect solution for me really. i mean, i usually crop in at least 5 maybe 10 pixels or more as routine anyway i forgot KISS, sorry

ok this ties in with a lot of my thinking atm. perhaps in the future, when i need just a little improvement to beat hubble ( ) i maybe look at any minor tilt issue i have. guiding, ill have another go tonight, hopefully, and share a log, but i was hoping 0.18 (1.5) ish would be ok considering my pixel scale and my other gear. i'm using astro sharp in my 'work flow' now and it seems an improvement over not using any blur related software. i doubt its as good as blurxterminator though. also looking at my subs there were some plane trails in it. not sure if doing 3 minutes over 2 minute subs is a big advantage for me shooting in colour.

yeah i agree, but before i do i need to make sure i buy the correct bits and peices that will work first time for my gear. jupiter is visible for a little while after dark from where i am, but for now im gonna try and concentrate on maximising hours on something. Until june ish, when i think stellarium is telling me m31 is back. ngc4889 "thousand galaxies" is interesting atm. who wouldn't want a pic containing 1000 galaxies?

How does it know o what my seeing is, when I don't know? Also, is it a accurate prediction/calculation?

After 3ppa in Nina and focusing main and guide scopes and recalibrating phd2 I took the attached pic. It's 23 x 180sec but clouds arrived full calibration frames. It's cropped and a quick post process (which I over did). My guiding was around 0.18 (1.6) in Nina. I think I could improve that with more medelling and maybe resorting to the backlash in Dec axis via a physical screw, but I'm not keen. It's possible my 3ppa was too accurate. Are the above numbers good enough for my gear? Also, hfr in phd2 was in red and over 4 most of the time and the zoom on guide star looked a bit big. Is this likely guide scope focus related? I have not changed gain control in phd2 think it defaults to 48. I also noticed one egg shaped star in top left but not really anywhere else in stacked image (not visible in the attached crop image). Likely a result of stacking not back focus? Lastly, there's a button in siril I think measures tilt and the top left of the quad overlay seems about 20% more than the other 3 which usually seem less than 10% different. Can a sensor tilt in just one corner, rather than in a plane? Sorry for continually asking more questions and requests for help. I do think I'm acting on them all and putting them to good use, but I might be a tad bias

Ty for this but I have a lot more reading to do before attempting this side project. Maybe when I run out of galaxies

i actually thought the moon a pretty dull target to image, but your images are nothing short of amazing.
