Nicely done there! And lucky you got away with no damage from the rain 🤞
Thanks. I managed to dash outside and slide the roof on just as the heavens really opened, a bank of heavy moisture laden cloud came in seemingly out of nowhere, 20 seconds later it would have been a very different story !

That’s a great result on a really challenging target, do you have a reasonably dark sky at your location?
It hovers around Bortle5\6.

HOO image comprising 59x600s Ha & 76x600s OIII, total integration time of 22.5 hrs.
This is the longest I've ever spent on a target and the Squid is extremely faint. You read about it but until you try and image it you cannot really fathom what an elusive target it is.
Processing it was very hard work, but I'm very pleased I got it. With a better quality OIII filter at 3nm instead of my 7nm I could have got more detail but all things being equal I cant complain.
The good thing is the data itself was very clean with a great SNR as you'd expect from the integration time.
AS294MM via WO Star 71 II.

IC 1396 (Sharpless 2-131): commonly known as The Elephant's Trunk Nebula
The Trunk (at the bottom centre of the image) is only part of this massive ionized interstellar gas cloud.
Over 2400 light years away in the constellation of Cepheus.
SHO palette, WO Star 71 & ASI294MMPro.
20x300s Ha, 17x300s OIII & 15x300s SII.
Imaged over three short nights, 13\14\15 July 2021

Thanks guys, it's appreciated!

That's excellent! Capturing images such as this were out of the reach of amateurs not so long ago.

At the top left of the partially processed image there are curved artifacts.
My first impressions are a light leak from somewhere.
The image consists of x21 luminance frames, calibrated with a master dark and x30 flats\dark flats.
The "light leak" shows up in each of the L subs. I haven't made any changes to the optical train, which is camera, filter wheel, spacers and coma corrector.
This hasn't appeared in any other images I have done recently.
I did consider next doors security light but it wouldn't show up on all the subs?
Possibly the Moon, but the artifacts look as if they're coming from the North in this image orientation.
The scope is a 150PDS.
It's got me flummoxed, if that's the correct way of spelling it!
Any help or advice is greatly welcomed.
Pete.

Just to be clear, would simply resizing the 2x2 binned image to the same size as 1x1 in PS be ok?
Or would I need something more exotic like APP\PixInsight?

NGC 281 The Pacman Nebula.
Named after the famous arcade game character, though to me it looks more like an Anglerfish sitting on the seabed.
Approximately 10,000 light years away this is a huge star forming region in the constellation of Cassiopeia.
The dark regions in the "mouth" of the Pacman are full of Bok Globules and it is in these where new stars are being born.
Photographed on the night of 25\26 Feb 2021.
Cropped image from WO Star 71 II.
26 x 300s Ha, 11 x 300s SII, 11 X 300s Olll
35 x darks, 50x flats & dark flats
Native bin 2x2, Gain 120, Offset 30, Temp -10°C

Lovely image. you have managed to make the star colour look almost like RGB stars, handling the pink halos really nicely....was this put together with Pixinsight's SHO-AIP?
Thanks.
No, all the processing was done in Photoshop only.

A widefield image containing various nebulae. On the left is SH2-157 The Lobster Claw Nebula, top just to the right is NGC 7635 The Bubble Nebula, below that more to the right is NGC 7538 The Northern Lagoon Nebula and the small star cluster under the Lobster Claw is NGC 7510 The Arrowhead Cluster.
Taken on the night of 22\23 January 2021 and reprocessed in the Hubble palette.

Managed to get some but not really enough Sll & Olll data on this. I've processed it in SHO and its coming on but by no means anywhere near being finished. I'm just happy to begin to see what I can do with the data I've accumulated so far.
Approx 3 hrs Ha and a couple of hours Sll & Olll each, with all the subs being 240s. I'll increase the sub lengths next time out, particularly Sll & Olll. Has a HR Giger-esque feel to it😬

If Andy Warhol did astrophotography....😀
First image is very nice, I like the colours used.
