  1. I’m not sure about the best way to share astrophotography processed with Affinity Photo. I decided to try the “Share your work” forum, but if there is a better way, please let me know. I am an experienced astrophotographer who has used a wide range of specialized programs for pre and post processing of astro photographs. These days I’ve been experimenting with my favorite general purpose image processor, Affinity Photo, along with the remarkable collection of astro macros developed by James Ritson. I have much to learn, but so far the results have been excellent. NGC 1955 is an emission nebula located in the Large Magellanic Cloud. (Technically, NGC 1955 is an open star cluster embedded within the nebula.) To collect this data, I used a remote telescope in Chile: 20 inch Newtonian, F 3.6. The object was imaged in three narrowband channels, Ha, OIII and SII. I processed the image with the Hubble palette, which is SHO, modified with a large shift in the green channel toward reds and golds. The built-in tools of Affinity Photo, and especially the innovative JR Macros, made this project a pleasure. NGC1955 SHO.tiff
  2. Asinh stretching (hyperbole arcsine) is a common practice in astrophotography workflows to extract data from a stacked linear image. I was hoping to be able to use the procedural texture filter functions to asinh stretch my images in Affinity Photo, but it seems the required functions aren't supported (see https://affinity.help/photo/English.lproj/index.html?page=pages/Filters/filter_proceduraltexture.html?title=Procedural Texture). Since the asinh function could be manually recreated with Log functions, I'd request either of the two functions to be supported. Thanks!
  3. Hi folks, Thought some of you might be interested in this stitching of 20 moon photos. Used SW 90x1250 Mak, Canon 1100D without lens taken through 15mm Plössl eyepiece. About 83 mag., Very clear skies. Edited with AP Panorama, various simple adjustment layers and the JR macro, Repetitive Bandpass Sharpening. You might notice a few black hairs from the camera sensor. Great software.
  4. Good afternoon everyone, I have recently joined the forum in the last 2 months and this is my first post. I'm not new to photography but have taken a liking to Milky Way images and struggling with the editing side of things. I am seeking any help or guidance on a technique or a 'how to' guide when editing in Affinity Photo. I've uploaded an image that I recently took, it is a panoramic consisting of 2 lines of 9 images with each frame a stack of 2 images. I took the original images in RAW/NEF and the above is a converted JPG. For some reason I'm just not that happy with the edit I have done and hoping someone more experienced can offer some words of wisdom. Thanks.

  5. 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 Options from session to session or allow user to set default values. 3 Calculate and display the total image counts for each file type in each group. Deep Sky Stacker displays this information and I have used it to find errors I have made in adding files. 4 Display the total exposure time for the Light frames for each group and the total exposure for all the groups. 5 Allow the user to save a file showing the files processed for each group. I have used this feature in DSS (Create HTML description file) to find all sorts of errors I have made in stacking. I have been through all the tutorials I have found and have been working with since it came out, restacking a lot of my old files. So if the functionality I have ask for above exist, please let me know. I plan to keep using Affinity Photo to stack my photos. thanks bob

  7. PiPP is software that converts .mov files (from my smartphone) to other formats. I've been trying to simplify my astrophotography pipeline, and would like to stack the outputted photos of PiPP. Unfortunately, no matter what format I try, the pictures come out all pixellated in the file list of the Astrophotgraphy Stack persona, and attempting to stack the files fails. Attached is an example .png file, but I have tried .fit and .tiff files. It should be Jupiter. My suspicion is that the issue is because PiPP outputs these files (verified tiffs and pngs) in 24-bit format. I have no control over that, that I can see reviewing documentation. Interestingly, opening these 24-bit files in normal photo mode render correctly. Am I just out of luck? Thanks!
  8. Hello, When trying to seriously capture faint deep-sky objects, with my rather unprofessional equipment (just a mirrorless camera and a 300mm lens), I tend to do it with several sessions over several days. Each day I add another session to the stack and see if I can squeeze some more photons out. Each day, however, I have to select all lights, darks, bias, flats of each previous session, over and over again, before adding the files of the new session. I didn't find a way to save these file selections, so that I don't have to do this repetitive task every session. Did I miss it somewhere or does it not exist? Thanks for any pointers. Cheers, Dom
  9. I'm still fairly new to both astrophotography and Affinity Photo, and although I'm not familiar enough with Photo to attempt all the processing on it, I do use the background removal tool at some stage of the processing on pretty much every image now to help remove or reduce a colour gradient. The four attached images are examples of how this turned out. I sometimes find I can also use the vignetting tool in one form or another to help with luminance gradients. I don't really have a set workflow at the moment and hopefully as my photography techniques improve, I won't have to use trial and error to try to fix the final images.
  10. Currently you have to manually click through each picture. This cans a looooong time when you have a lot of frames. Using the "Select best light frames" does not always work or has unexpected selections. So need a way to visually see a grid of frames to visually identity problematic frames. Thanks
  11. When you create a new Astrophotography Stack, all of the configs, photos, etc that were used is sort of "lost" because it is merged into a "Stacked Imaged" pixel layer. Would be great if this data was retained as sort info/data info. Thanks
  12. 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!
  13. Hello, Would anywone be aware of a plugin that would allow asinh colour stretching, as used in astrophotography? I read this plugin exists for Photoshop, and PS plugins should be compatible with AP (or am I wrong?), but I have absolutely no idea where to find the plugin. Is it integrated in the original PS setup? As an aside, would functionality like asinh find its way in AP's set of astrophotography tools...? Many thanks for pointers. (edit: Just discovered James Ritson's astro macros. Some of them handle the arcsinh stretching.) Cheers, Dom
  14. 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
  15. Hello, I'm hoping somebody can shed some light on this. I'm trying to edit an astro stack, however when I apply a curves adjustment, (manually or adjusting the automatically applied one during the stack) there is either no or very little histrogram data, despite the standard histogram working as normal, and other adjustments such as levels working fine too. While the master selection in curves isn't working, the red green and blue are, as well as grey and so on. I have a pretty decent Windows machine so performance isn't an issue. I thought it may take a short while for the histogram to render in but it never does. Funnily enough, I downloaded a sample stack online of the same subject, same document settings (32 bit etc), and it seemed to work on that image, so I'm at a loss. Any help would be appreciated. I've attached screenshots and my project file for reference. Thanks 452161177_TestStack.afphoto
  16. Hi, I'm an Affinity user trying to process astrophotography images. The problem I would like your help with is whenever I work with nebulae I like to reduce the number of stars and size of stars in my photo so that the nebulae stand out. Unfortunately, when I use Star Eater or Star Eater Extreme to make the stars shrink, dark rings appear around the stars. (See photo below.) How can I avoid making those dark rings appear? I realize the rings are a consequence of my shrinking the stars.
  17. Once Astrophotography stacking is started (click on Stack) the process can not be canceled: If there are 500 light images to be processed, this will take forever. - Personally, I don't like it to end an app by "Force quit…" Best regards, Roland
  18. Is it possible to create a composite with several astrophotos such as the Sun, Moon, Galaxies, Nebulae and Star Clusters? If yes, can someone point me out a tutorial for that, please? The ones I see online are having a foreground or background. And I have to start from a new document with following measurements: width: 2000mm & height 800mm. Thank you in advance!
  19. Hi, I've been experimenting with Affinity Photo over the last few days to see how well it performs vs Astro Pixel Processor for aligning astro images and applying levels and curve adjustments. I stacked 95x10s subs of the Globular Cluster NGC-6723, which represents a tiny portion of an original image of the region around Corona Australis (which you can see on my Astrobin page here). Image (a) is an unaligned stack, to show the range of mis-alignment; Image (b) is the same stack aligned and adjusted using APP; Image (c) is the same stack aligned and adjusted using Affinity Photo. The levels and colour balance are slightly different, but the alignment done by Affinity Photo is every bit as good as that done by APP. I find Affinity Photo much easier to use than APP, and much more versatile for other image editing tasks. For me, Affinity Photo replaces both APP and Photoshop, which IMHO makes it excellent value. Gary ===== PS : I have no connection with Serif - I'm just a new user who is really pleased with the product, and the responsiveness of their technical support team.
  20. 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 provide me with support on this issue? I have attached a screenshot here (using my phone as I can't grab a screenshot due to your programme crashing every time).
  21. Hi, First I would like to express my appreciation for the work being done on this product, this is just amazing. I have been searching a bit but did not find any immediate result. How does Affinity deal with a stack of frames when some are taken before and some are taken after a meridian flip (so when viewing the individual files you will notice not all have the same orientation)? Are these handled automatically by Affinity when stacking these files using the Astrophotography Stack persona? Thanks in advance and best regards, Bart
  22. Hello, I've imported around 15 photos to Affinity Photo into the Astrophotography mode. On most of these photos there is some satellites/meteor trails, but they are gone after stacking. Is it that Affinity is so good at removing them or does it simply reject these frames ? Also is it possible to see the total exposure time after stacking ? Thanks
  23. Hi, Does the function to stack astrophotography images consumer temporary disk space? How much is this usually (for other application with similar functions this is usually roughly the same amount of light frame data) and where is this temporary data stored? Björn
  24. Hello, I took pictures of this past solar eclipse. They are in jpeg. While taking the pictures with a filter I was able to see the crescent shape of the moon over the sun. However the pictures area of the sun is blown out I cannot see the crescent. Can Affinity correct this please ? If so how? thanks, Charlie
  25. 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.
