  1. Thank you everyone for the positive feedback - and reading through the comments I must namecheck @Adreneline as it was October last year when I had just 'discovered' the Auriga region for myself that Adrian posted a widefield of Spaghetti nebula and IC405/410 showing how close they were in widefield angular terms - and thats when I got the inspiration to embark on this project, that has been an obsession at times both on the imaging side and possibly more so on the processing.... but thats why we do this right ?
  2. All, my first colour mosaic, a lot of challenges and issues with capture, clouds, orientation of panels etc.. Processing - laptop crashes and trashed SSD so lost all separate channel integrations for one panel. Used APP mosiac mode to integrate Ha panels in non-linear state.... and a whole lot more..... Anyway huge field of view Pixel scale: 6.018 arcsec/pixel Orientation: 249.222 degrees Field radius: 7.558 degrees Samyang 135mm / ASI1600MM Over 30hrs+ in 240s subs Optilong Ha / Sii / Oiii Began the capture of the Flame nebula panel in October 2020 - co
  3. I am just south of Northampton, so can image East-South-East across countryside, but its being rapidly built on. Clear Outside has me under Class 5 Bortle
  4. I've been following the progress of @tooth_dr on his multi panel mosaic project of the Spaghetti Nebula as we have been running in parallel with imaging this elusive object. For my project I have taken a wide- field approach using my Samyang135mm lens with ASI1600MM and Optilong narrow band filters. I posted my initial image of Ha last month. This has been a very challenging object, the hours required, the number of subs (CMOS camera), processing and UK weather/skies. I should try and get more Sii definitely and better Oiii, but I want to move on and put my APO back on the mount
  5. @carastroI am under Bortle 5 skies, at least I when imaging NNE to SSW , the remainder of the sky around me is quite light polluted to my North is Northampton and the big warehouse park and to my West is more warehouses. I am using a 7nm Ha filter,
  6. Thanks Mick and Lee, appreciate the feedback and encouragement - Actually got clear skies tonight - so hopefully as long as it stays that way , I can bring down a few hours of Oiii. I did overlay the mosaic on Kstars with a moon image - I assume Kstars moon icon is scaled, this is a fair chunk of MW
  7. No idea how I managed to get 5.5hrs of subs on this extremely faint nebula this week. I rejected about 45mins due to clouds - no surprise. so this is 4.75hrs made up of 240s subs taken with Samyang 135mm at F2 with ASI1600MM and 7nm Optilong filters I used Pi4 running Astroberry with KSTARS/EKOS/INDI controlling everything Integrated with APP Processed with Pi and PS I have also included a quick screenshot form the ICEtool used to stitch two images that shows what I am trying to achieve , a rather large swath of Auriga as a 4, possibly 6 pane mosaic. I am however thinking is
  8. Another amazing set of data - kept my evenings interesting over the past week. Its an extraordinarily difficult image to balance, huge dynamic range. I found it extremely challenging to get the balance right and also put colour across the image that highlighted the different gaseous regions of M17 and where the Ha, Oii and Sii contributes to the overall false colour image. I used pretty much every tool in the box, Pi - initial stretch with histogram and creation of starless versions with Starnet++ PS - massive stretching of each of the starless images to get a colour into the mix, I f
  9. I recently 'discovered' this fascinating Auriga region in the night sky and am absolutely amazed at the huge Ha regions that look like footballs in space. I've seen high resolution images of the Flaming Star Nebula and also the 'Tadpoles region in IC410 framed individually, but when you see everything together in this wide field context and including the two Messier open star clusters, for me makes this hobby so worth all the effort. Having done more research and now realise that the huge 'Simeis 147; "Spaghetti Nebula"' is just next door, this could turn into a mosaic project as the FOV usi
  10. Very interesting time processing this great set of data - thank you SGL and the Ikarus Observatory project. This dateset gave me a good reason to get on and research alternative combinations of the narrowband channels. I used PI for the initial stretch and then used PixelMath to combine and created two options using what is referred to as Dynamic Combinations that I found on thecoldestnights website, https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/ I used these equations Sii/Ha/Oiii : R = (Oiii^~Oiii)*Sii + ~(Oiii^~Oiii)
  11. Sorry forgot to put that in OP - Camera used is ASI1600MM Pro with yes a samyang135mm at f2 mounted on alt-az EQ6
  12. Thanks @DougM43 appreciate time taken to comment. thanks for posting the equation Adrian - I will have a play later in the week with PI on my data. I got to this depth effect purely by accident truth be told by using tools and actions in PS plus the enhance dark nebula script in PI and then combining that output in layers with PS and selective sharpening and whole bunch more including using Starnet to remove the pink stars and then in PS bring in a noise reduced and sharpened Ha star field Bryan
  13. Been great to have a few nights of clear sky - I captured this last Wednesday/Thursday last week. I have only Just getting to grips with narrow band imaging/processing and I am sticking with tried and tested SHO Hubble palette for now, but very interested in the percentage combinations like the wide field recently posted by @Adreneline - Cave, Bubble and M52 - to name but a few. I'm assuming the colour palette combinations are implemented using PixelMath functions in PI - I will do some reading and jump into the processing threads to find out more I think. But for now here's my latest SHO na
  14. I agree - the blue and golds seem normal given the long legacy of Hubble images but there are such a lot of twists and turns in the way narrowband channels can be mixed into a visual palette. I have just been reading quite a bit this evening and downloaded Annie’s Actions and applied that to my data - it’s different again but the stars are really pink - which is SHO interpretation. anyway looking forward to imaging more narrowband through winter months Bryan
  15. @MarkAR ; @don4l - appreciate the feedback, I've been digging into the data for 'true' hubble SHO - pushing it all to the max....I think I will stop now as limited data set and this is as close as I think I can go to what is seen as traditional SHO Hubble: Any preference between first version and below ?
