Makes me glad I don’t have neighbours at the moment, only sheep.

Great first attempt, way better than my first Astro image which was Andromeda too.

Hi and welcome, best night skies I’ve ever seen whilst travelling around down under. I soon learnt the hard way not to walk under tress at night though.

I've just come across this methodology of processing, to preserve star colour etc.
I process everything in Photoshop, where in the processing work flow should I implement this? At the moment I open the image in PS, and do some initial linear stretches to reveal some stars, and then separate the stars from the nebulosity.
I'm not sure at which point I should apply the arcsinh stretching methods.
I thoroughly recommend this tutorial for the initial arcsine stretch, there’s a couple of more tutorials on his channel worth looking at too

Hello and welcome, lovely dark skies, pity about the clouds though lol.

I was in tears too, because of the cloud cover.

Thanks for doing this. I have Photoshop 6 which doesn't open Canon RAW files (.CR2). So I have to convert them to TIFF to fiddle about with them.
I think TIFF is the same as RAW (as in it doesn't compress or lose information), but please correct me if I'm wrongI believe you’re correct regarding Tiff files. If you do stack images next time use Sequator (as suggested earlier it’s free) for Milky Way and nightscape images. Also another alternative to Lightroom/camera raw for editing images is Darktable, again another free bit of software that’s rather good. Loads of videos on YouTube regarding above software, nightscape images & Alyn Wallace are worth watching for imaging and editing tips. Good luck and look forward to seeing your next image, especially for bottle 3 skies.

I tried a stretch in Photoshop, but the histogram was already about right, so there wasn't much stretching to be done.
Yes, 10 sec was the longest exposure I could use and still get round stars (see original post). I was using the 10sec delay on my camera (to abolish shake). It's an EOS 750D
I'll try stacking next time then.
For Milkyway and nightscapes imaging I prefer to use Lightroom Classic/camera raw in photoshop, and have a play around with sliders to make it pop out. Definitely stack next time out thou

It's not an issue of Photoshop itself, it's something to do with the Camera Raw plugin; the way I got around it was opening up Photoshop and under the Preferences menu going in to the options for Camera Raw (it may take some digging around as it's not the most front and centre of things) and then in the file handling setting TIFF to "Automatically open all supported TIFFS".
The other way around it, though not tried this is as you say it opens in Lightroom, either use the Edit In function on the context menu (and open as smart object) or export it as a TIFF from there and open it.
Works for me better than the LRC method, cheers

Well, Adobe don't seem to all over it
Luckily I haven't updated for a while. I had a load of trouble at the last big update. So I'll wait to see how this fans out. I very much doubt there is anything in the big update that I've been struggling without!
I've been thinking about moving to something more Astro Specific as I pay a lot for it and only use it for astro imaging and don't come close to using it to its full potential. How Adobe fix this (or not) might be the push I need.
Totally agree I’m hoping they’ll get a fix this week, If not then 1) I’ll give affinity another go(I purchased it last year when it was on offer) or 2) be brave, take the plunge and get pixinsight. That said I do use Lightroom for photography, so stuck between a rock and a hard place.
I am right in thinking if you cancel the Adobe subscription you’re unable to use any of them, is that right?

There seems to be a bug in PS, in you can, import the tiff file(s) into Lightroom Classic then export the file(s) as 16bit tiff files into a sub directory/ or rename. They should open ok then, same with starless Starnett files. I’m going to assume PS will find a fix soon.

No issue seen here with TIFF files saved from APP using sRGB v2.1 or sRGB v4.0 (in 8bit, 16bit or floating 32bit) or any other application then loaded straight into Photoshop 2022 . 😕
Seems to be DSS and/or starnett issue for Astrophotography, as the posters on the Adobe thread are all stating the same, there seems to be issues with other non Astro programmes too. It’s also not opening historical stacked TIFF files either.
link to thread below if anyone interested

Have not tested DSS yet, but I have the same problem with opening files from starnet++ after update to PS 2022. Same error message...
Yes starnett++ is affected too as I found out yesterday. However, on the Adobe thread I’ve been following a user has said if you import the TIFF file into Lightroom classic and then export it as a TIFF file from there, it should open ok. I’ve tried this on DSS files and it works, I will assume this will also work on starnett TIFF but I’ve not tried it yet.

Sorry it's been a while since I've used DSS
Maybe go back a version and see if the problem still exists
First thing I tried. I am however not alone with this issue.

Try 16 bit
Alas no same error message, I can open 16bit tif files that I’ve saved in photoshop ie starless images out of starnet++ and with the layers. I’ve found a thread on Adobe with users having the same problem after the update. Strange one this.

Ah I thought dss only output in 32bit tif. I shall give it a try.
thanks

Hi Guys,
Just wondering if anyone else is experiencing problems with opening tiff files straight out of DSS since the update.
I get a error message stating it’s unable to complete as incorrect file type.
I’ve reverted back to previous version but alas I still have the same message appearing.
this seems to affect all 32bit stacked files that I’ve created with DSS. I can open them in Lightroom but alas edit in photoshop option doesn’t work eitherAny ideas or suggestions
Thanks
Andy

Well had a nightmare with the subs on this target, I had over 7 hours total of SHO. The see conditions were rather bad over a 3 night period which stretched over 3 weels. In the end i used to 20 subs 3 minutes per each channel as the subs were awful. Dithered with flats and dark flats. SharpStar 94 EDPH ASi1600mm, ZWO filters.
Processed with DSS, Photoshop and Starnet++

Hello and welcome from North Wales
M31 Andromeda LRGB
in Imaging - Deep Sky
Posted · Edited by Andy R
First crack at processing M31 using Pixinsight, I have HA data to add but it seems my flats didn't work well enough to remove vignetting/gradient (I'm assuming that's what it is or dew on the sensor). Can anyone recommend a Pixinsight process to remove this? I did use DBE, but maybe not well enough.
Anyhow this was imaged back in September with about 35 x 60second subs each LRGB. Flats and dark flats used.
Pixinsight is quite a programme. Any CC would be welcome
