  1. 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.
  2. 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
  3. Thanks guys, it's appreciated!

    That's excellent! Capturing images such as this were out of the reach of amateurs not so long ago.
  5. The Iris Nebula.
  6. LRGB image, taken as I was waiting for Cygnus to get high enough to image there. 20x60s L, 10x60s RGB.
  7. Both are HaRGB images. The Crescent and the Tulip.
  8. 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.
  9. 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?
  10. Globular M13 under a full Moon, taken using LRGB filters. Some horrendous gradients to deal with due to the Moon but I'm reasonably happy with it considering the conditions. 15x120s Lum, 10x60s RGB.
  11. 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
  12. Managed to image during a four hour session last night, mostly through a some very high and thin layer of cloud which thankfully didn't interrupt the guiding too much. Only 1.5 hrs Ha and an hour each of Sll & Olll.
  13. Thought I'd go for a slightly different perspective on this. It's usually pictured "side on" with the prominent gas "tail" either going left or right. Tipped on it's side for this image this image, its going up.
  14. Taken last night 11\12 Feb in Ha & Sll.
  15. Thanks. No, all the processing was done in Photoshop only.
  16. 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.
  17. 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😬
  18. NGC 2175 The Monkey Head Nebula in the constellation of Orion. Taken in the early hours of 1st Feb 2021, only 50 minutes of exposures due to offending trees for this image with an 84% Moon in the sky and a thin layer of high cloud so can't complain. 10 x 300 sec Ha 15 Dark, 20 flat, 20 Dark flat ZWO ASI294MM & WO Star 71 ll Cheers, Pete
  19. My first attempt at a bi-colour narrowband image. I plan on adding more data to this as time goes on, certainly some Olll and perhaps adding RGB for the stars. 40x240 Ha, 20x240 Sll. Gain 120, offset 30, temp -10°C, bin 2X2 ZWO ASI294MM with WO Star 71 II Cheers Pete
  20. IC 405 SH2-157 widefield
  21. Using a WO Star 71 Quad, so has the built in flattener. Flats taken using a white screen app on my tablet. Regards, Pete.
  22. I'm using the 294MM and haven't noticed this on any of mine. Here's a stretched Ha flat circa 25000 ADUs. The sensor is clear with none of the surface staining as reported by some on CN (it's the first thing I checked when I opened the box!). Perhaps the staining was a batch that slipped through QC checks.
  23. Thank goodness for FLO. I've noticed the price increases elsewhere, particularly on one of our usually good value Teutonic friends websites.
