  1. Version 2, this time I have used Starnet++ to process the nebula independently to the stars. Again the processing has been done in Affinity Photo.
  2. I’ve had a quick play with this in Affinity Photo. I will give it a proper go later.
  3. When you launch it, you should get a dialogue box saying there is a newer version available.
  4. Updated I like that we can now enter x & y values for more accurate curves. Maybe someone will create arcsinh curve presets
  5. Mark Now that version 1.9 of Affinity Photo has been released it is possible to place points on a curve as x & y values between 0 & 1. Would it be possible to create arcsinh preset curves in Affinity Photo? Regards Darren
  6. What a stunning image
  7. There is no need to keep PS2 if it is just for combining the mono images into a colour image, if you watch my video you will see how easy it is.
  8. To make the process a little clearer I have recorded a quick video showing how I combine mono images to create a colour image using Affinity Photo. https://youtu.be/MBZ5W5YKVg4 The images in this video are just single 5 minute subs taken with Red, Green & Blue filters, that have been aligned using Astro Pixel Processor and saved as Tiff files. I hope it helps.
  9. The method I use is to paste each of my mono images into a new document as a layer, then use the colour channel adjustment layer on each of the new layers to colour them as either red, green or blue. I have set up presets for each colour to make it quick and easy. Then you just set the blend mode to add for each of the layers. This produces a colour image, if you then create a stamp layer that combines all the visible layers (ctrl, alt, shift & E) this creates a colour layer that you can further process. A good video to watch about colour is this explains splitting a colour image into each channel and recombining as used in my method. this video explains how to user the colour channel mixer
  10. I had another go at processing the Horsehead from the same dodgy data. Is it an improvement? Darren
  11. Due to the bad weather and having no new data to play with, I have dug out some of my early astro imaging efforts. I wasn't expecting much as the source data is really bad. The RGB data was taken with an stick Canon EOS 1000d through my C8 with a 0.63 FR. Now the focal reducer I used at the time was one of the dodgy Chinese knock offs that means that the back focus was all wrong creating misshaped stars towards the edges and really bad vignetting, most of which has been cropped out because of the size of my Ha data. The Ha data was my first every attempt at Ha when I first got my AtikOne 6.0. So the Ha data has issues as well. The Ha was taken using the same scope and focal reducer set up as above, so is suffering from the same issues as the RGB. But it also has the additional problem of being slightly out of focus, so some stars are little donuts. From the above, you would think why bother, so did I, but I really wanted to try some new techniques and try to combine data from different sources and image scales. I am just starting to get used to Astro Pixel Processor, Starnet++ and Affinity Photo so thought that this would be a real test. It was, I stacked the Ha & RGB files in APP so that the resulting files where same size and orientation, I also used the batch crop and rotate tools to get the framing I wanted, and to cut out as much of the crud as possible. I also used the background / light pollution removal tools before moving the two files (RGB & Ha), on to Starnet++ where I created starless versions of each. I then did the rest of the processing in Affinity Photo. Its not the best image I have ever produced, but from such bad data I am quite pleased. I suppose the moral of the story is never throw away any data, however bad. Thanks Darren
  12. This was from my last imaging session of 2020, The Monkey Head Nebula taken on Christmas Eve.
  13. 20x5min of Ha OIII & SII USING AN Atikone 6.0 through an Equinox 80 pro with a televiewers TRF2008 0.8x focal reducer. In Astro Pixel Processor I applied a 3x factor to both OIII & SII when combining the channels. I then used selective colour adjustments to balance the colours
  14. No stacked and preprocessed in Astro Pixel Processor and finished off in Affinity Photo
  15. Christmas Eve I managed to get 5 hours on NGC2175 the Monkey Head nebula
  16. What an image absolutely stunning
  17. 2020 hasn’t been a great year for anyone, but we’ve had a good comet, and some clear nights. I haven’t been the most productive, or even a very good imager this year, but I’m quite pleased with what I’ve learnt, narrowband has been a revelation . So I thought I would share a few of my images, and a video I put together or them. Thanks for all the great images and tips that have been posted. Wishing you all a happy Christmas and a great 2021. Darren
  18. You can minimise stars in exactly the same way as you do in photoshop, but the filter is called minimum blur under blur in the filter menu.
  19. I have the Baader LRGB set all parafocal and have done me proud. I also have the Baader 7nm SII, Ha & OIII filters again parafocal and performing well.
  20. Thanks Bryan, Affinity Photo is a photoshop like program from Serif, its only £48 as apposed to £9.99 per month for photoshop.
