Imaged from East Yorkshire 19th Jan early hours. Mono composite image, 15 x 15 sec exposures on LRGB via 150PDS Newtonian. Pete.

JE1 The Headphones nebula. A 14th magnitude planetary nebula in Lynx. Imaged for 19 hrs total integration time over several nights Dec '22 & Jan '23 and processed as HOO (14 hrs Ha & 5 hrs OIII - unluckily most of these sessions had a strong Moon hence the low OIII to Ha ratio). Cropped image via 150PDS. Pete.

Superb ethereal image. I do like that.

In the heart of the Heart... Imaged over five nights during a very wet and windy November 2022. Comprising: 9.0 hrs Ha, 4.4 hrs SII & 4.5 hrs OIII. Plus the usual calibration frames. Pete.

For Halloween... SHO image, 31 hrs total integration time (9 hrs SII, 16 hrs Ha, 6 hrs OIII), imaged over eight sessions Sep 29 to Oct 24. Gamma Cas really dominates the scene. Cheers, Pete.

SHO: Just under 15hrs integration time over four nights. 150PDS.

I'd add keep your current master dark flat too, if you use them. Sorry didn't fully read the excellent advice from Catatonia properly !

Simply superb. The detail is excellent.

Cederblad 64: Also known as Lowers Nebula The Lowers (father and son) were amateur astronomers and found this nebula on one of their photographic plates taken in 1939. It is a relatively faint region emitting doubly ionized hydrogen. There is no accurate measurement as to the distance of this nebula, although best estimation is about 3300 light years. Taken over three nights 11\13\19th January 2022, total time for the image is 7 hours. 74x300s Ha, 20x60s R,G,B. Pete.

IC 443 in SHO Just under 16 hrs integration time over four nights early January, nice to have a run of clear skies! 115x300s Ha, 37x300s SII & 38x300s OIII

Thankyou very much !

Thankyou. It was just over 5 hours Ha and three each of OIII & SII. Must admit the OIII did surprise me under the conditions. The SII was very subtle. Thanks again!

IC 410 and the famous Tadpoles in SHO Just over 11 hours total integration time over two nights., 15th/16th & 16th/17th December. The OIII did better than expected considering the Moon was only a few days off full. Pete.

Aesthetically the top one looks nicer to me, but...there's a hint of IFN in lower (more agressively processed?) image.

Superb. The HOO is my favourite.👌

First attempt at The Dark Shark. 5.5 hrs LRGB, it needs much more integration time but I'm happy with this as a first go all things considered. Bortle 6 plus assorted neighbourhood xmas lights. Pete.

The latter 👍

Personally I combine them together after I've collected all the data, when I'm ready to process. This way it doesn't matter when the data was taken, could be months or even years apart - as long as you have the original subs (and calibration frames) to re-stack with. There are actually a few SII subs in here from February this year. Others may do it a different way but this seems to work for me. I use DSS & PS and so haven't dabbled into the dark art of PixInsight... yet!

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

IC405 8hrs SHO but processed with more muted colour than I normally would. Imaged over two nights, 1\2nd & 6\7th Dec. Pete.

Widefield shot of M1 in HOO. An hour each of Ha & OIII before Storm Arwen set in. Hard to imagine the violence nearly a thousand years ago when the star exploded, such a tiny and serene looking thing now.

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 !

NGC 1499. HaRGB with just over five hours total integration time, including (oh the horror!) a rain shower into the open obsy. No harm done thankfully.

M45 imaged through a three hour break in the really poor weather at the moment. Cropped image, AS294MMPro via WO Star 71 II. LRGB comprising 29x180s L, 20x120s RGB each.

It hovers around Bortle5\6.
