  1. I'm a beginner in astrophotography processing. I have watched the YouTube videos by James Ritson but I do not understand all the terminology or how to get all the files (Light frames, Dark frames, Bias frames, etc.) or even what they are. I really need an introduction to astrophotography processing in Affinity Photo. Thanks very mch.
  2. Hello, I recently purchased your software as all the videos showed how well it works for astrophotography. I was particularly impressed with how fast your stacking process was in your videos. However, each time I use your Astrophotography Stacking process, once I hit stack the whole programme just crashes. I left the programme alone for over an hour. Not even Deep Sky Stacker takes that long. This is deeply disappointing and contrasting to what your videos demonstrate. My laptop has a i7 quad core processor too so it's not exactly slow or lacking power. Please can you provi
  3. Hi, In the Arrange menu, there's an item "Align Layers By Stars". I've seen this function available and working, if I have a document where the layers stem from the Astrophotography Stack. When I created a new image from TIFFs which contain stacked images (e.g. as the result from Deep Sky Stacker), this menu item is not available. I don't understand why? Thanks in advance! Björn
  4. I've been playing with the new 1.9 release with some astroimaging data I have and it is pretty cool stuff - great job! I am intrigued by the "Remove Background" filter. I have other astroimaging software which handles fairly complex light gradients but having a tool I can show new imagers how to use in Affinity is an attractive idea. I watched the OSC stacking video and around 11:30 in the filter is discussed some so I got an idea of what it does. It seems to mainly be for neutralizing the background color. But it was mentioned it can remove gradients as well. I made a si
  5. It appears that currently the astro stacking uses the intersection method to stack all images. Would it be possible to have the option to get a mosaic of all pictures? Or/and use a reference frame? (I know, I know, it's not DSS, but just asking) Cheers, Dom
  6. This panorama is created using several Affinity Photo tools. Star Brushes, Pattern Layer, Equirectangular Projection. Steps 1. Document with a 2:1 ratio 2. Pattern Layer 3. Seamless stars texture (two layers) 4. Equirectangular Projection 5. Replacing distorted parts (poles) The original 4K texture was rescaled to 2K, using the "Nearest Neighbour" method. To view the finished result in 3d space, see Blender file: Space_360.blend This diagram explains the reason for the 2:1 aspect ratio:
  7. Hi, I am using Affinity Photo extensively for my Deep Sky Astrophotography workflow. I have a new camera that has a bit depth of 12. The FITS files created aren't scaling the 12 bit to 16 bits, i.e., the maximum brightness value is 4095 and never 65535. How is the Astrophotography Stacking tool processing these files? For comparison: in Deep Sky Stacker, I need to define a scaling factor of 16 so that the very dark images are lighter and stars being correctly identified. Thanks in advance! Björn
  8. Hi, I'm using Affinity Photo extensively for my Deep Sky Astrophotography and I have a problem when working when I try to create an LRGB composite. While the procedure of adding the RGB channels and using the recolor adjustment works quite well, adding the luminosity layer is a problem for me. In my opinion, the RGB channels should define color and saturation, while the luminosity layer should affect the luminance only. According to this post, blending the luminance image with the luminosity blend mode changes the color. Something that I experienced myself. To resolve the issue,
  9. Dear users, I have problem to start up the workflow in Astro Stacking LRGB. I can load the 16-bit Fits-data (monochrome) into the file list but no action can be done after that. No file can be open for preview or stacking. (actually I can open 8-bit fits file for preview but no stacking). I follow the very clear and good demo video-clip but it don't work like that. How to initiate the astro- workflow with final result in a LRGB-composition ? my set up is windows 10 (new update since last week), Lenovo 1Tb/16Gb/ NVidia 1660 4Gb.
  10. Hello, I updated Affinity Photo today from 1.9 to 1.9.1 With 1.9 the Astrophotography Stack feature just crashes and didn't work at all. With 1.9.1 the Astrophotography Stack feature is incredibly slow. I have taken a screenshot of the status bar after 30mins. I'm only stacking a small number of frames consisting of: Lights frames = 22 x 4min @ ISO500 Darks = 17, Bias = 50, Flats = 50. All frames are CR3 Raw files. My laptop is an i7 quadcore so it's not exactly slow. My complaint is that your YouTube videos show the Astrophotography Stack feature c

  12. I have been using Deep Sky Stacker (DSS) and would like to see the following features in DSS added to Affinity Photo's Astrophotography Stacking Persona. 1 Allow the user to save and reload Astrophotography stacking settings, groups, and, files created in the Stacking Persona. This would allow adding new images from night to night and removing Groups and files that were found later to have problems. At present the user has to start over or have I missed something. This is a text file in DSS. Maybe allow the user to load and existing DSS file list. 2 Retain Stacking and RAW
  13. Hi, I just tried some of the new astrophotography stacking features. The stack can be generated and processed quite easy. But when exporting these files, they create some ugly grey blocks on the image (see screenshot). Same blocks appear, if zooming in to a very high zoom level. Using AP 1.9 on M1 with Big Sur.
  14. Using my main desktop machine (specs below) the astrophotography stack crashes after about 30 seconds of performing the stacking process if more than 8 files are set to be stacked. Have tried the 1.9.1.944 beta and this also crashes under the same conditions. OS and drivers up-to-date. Machine spec: AMD FX-8300 Eight Core Processor 3.30GHz 8.00GB DDR3 RAM Nvidia GeForce GT710 2GB. Driver 27.21.14.6140 Windows 10 Home 64bit. Version 20H2
  15. I've been tinkering with Affinity Photo for awhile now (a 15+ year user of PS) for my astrophotography and when I saw the 1.9 release I had to try out the new stacking functionality. This is a simple stack of 180s H-alpha frames of the Horsehead nebula stacked and post-processed in Affinity Photo: More information here: https://www.astrobin.com/iz5cjv/ I'm very excited about this new release. I mentor local astroimagers at our astronomy club and having a full featured option like Affinity Photo at an accessible price is a real game changer. Michael
  16. I am stacking several night sky shots using HDR Merge . The subject has a shot of the Moon very bright set at correct exposure. shots allowing for moonlight on foreground and a large structure building in the midground .The problem I am having is that when I adjust the tones after merge with an acceptable level I cant get the sky dark enough to show off the stars its either one or the other leaving far too much editing as a result . The foreground has snow in it illuminated by the moon the sky has to be dark to show off the Moon and stars, the Horizon has a residue of after sunset
  17. I shot this using my Celestron 25x100 astrobinoculars using the Celestron NeXYZ smartphone mount and my iPhone 12 Pro 2x telephoto lens. Shot with Procam app. Processed on Affinity Photo latest beta. Showing both original and processed shots. The sky was also made from scratch - the stars were added for effect, shot handheld with iPhone 12 Pro (no astrobinoculars) and Nightmode which is quite impressive.
  18. Now that I have made the switch to AP I am re-working many of my astrophotography macros. I will share them here with brief instructions and encourage others to share theirs. All my macros are for Windows OS This set of 3 takes the basic individual monochrome filtered R G and B images and converts each into a colour channel. Load each RGB file separately into AP, Run the respective macro and copy the output of each into a single AP layered document, then set the blend mode of each to add This will output a single RGB non white balanced file grey to blue.a
  19. Greetings Readers, I have been photographing the moon to obtain ultimately 8 pictures depicting 8 phases. Presented today is my latest image: The Waning Gibbous Moon. This Waning Gibbous Moon appears opposite to the Waxing Gibbous Moon and both these moon images are displayed in this composite image. The second image shows these moon images as obtained from the camera raw files. Notice that the waxing moon is appreciably larger than the waning moon and this is because the moon is now further away away by 30,526km ! Tomorrow (10-07-20) will be the best time to obtain an image of the
  20. Greetings Readers, In collecting moon pictures to make a composite picture we received 5 very clear days and nights. On each night I took a picture of the moon and processed the images in Affinity Photo. These images show the waxing (getting brighter) moon on 5 consecutive evenings. The first (waxing crescent moon), third(first quarter moon) and fifth(waxing gibbous moon) seem good enough to include in my final composite picture. The top sequence contain the original images and the colour saturated version is the bottom sequence. Jeremy
  21. Greetings to All, Here is a picture of the moon to be included in my montage of moon phase images in colour. This image is short listed to be included in my montage of moon phase images in colour. All image processing was done in Affinity Photo (excellent program!) For those who are interested: The colour saturation was obtained in a 5 stage process (5 adjustment layers) of gradually increasing levels of colour saturation. This colour saturation process will amplify colour noise so one must start with a "low noise image. The low noise image was obtained by stacking 15
  22. I am still learning my way through AP and have started re-working some of my old images which are now much improved vs my old editing techniques in PS Here is my 1st main attempt using AP This is IC5070 Pelican nebula in Cygnus tone mapped using Sii as Red, Ha as green and Oiii as Blue. 9x5min each colour channel. Stacked and aligned in Astroart, Initial stretching and development in Startools then colour re-combination, balancing, additional tone mapping and sharpening in AP. BTW - AP did these final stages in a fraction of the time PS takes. Clear Skies
  23. Hi all, this is my very first post on Affinity Forum and I have very little experience with Affinity Photo. I'm an astrophotographer and today I'ma trying to postprocess a Moon image to create a "mineral moon" image. I usually use an astrophotograpy dedicated software but now I want to try to process the image with Affinity. The very first step of mineral moon processing is perfectly white balancing the moon disk by aligning the RGB hystograms. In my case, as you can see in the attached picture (Image 01), the moon has a strong yellowish/pinkish color (due to some preprocessing I
  24. Hey guys, as a first video on my new channel, I created a tutorial for a basic astrophotography editing workflow in Photo. Hope some of you will find this helpful - any feedback appreciated!
