  1. 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.
  2. 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!
  5. 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.
  6. Aesthetically the top one looks nicer to me, but...there's a hint of IFN in lower (more agressively processed?) image.
  7. Superb. The HOO is my favourite.
  8. 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.
  9. 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!
  10. If Andy Warhol did astrophotography.... First image is very nice, I like the colours used.
  11. IC405 8hrs SHO but processed with more muted colour than I normally would. Imaged over two nights, 1\2nd & 6\7th Dec. Pete.
  12. 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.
  13. 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 !
  14. 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.
  15. 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.
  16. 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. Pete.
  17. 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
  18. Thanks guys, it's appreciated!

    That's excellent! Capturing images such as this were out of the reach of amateurs not so long ago.
  20. The Iris Nebula.
  21. LRGB image, taken as I was waiting for Cygnus to get high enough to image there. 20x60s L, 10x60s RGB.
  22. Both are HaRGB images. The Crescent and the Tulip.
