  1. 22 minutes total from 4 and 6 second exposures Loosely followed processing method from https://www.youtube.com/@AstroFarsography titled "Astrophotography Editing Tutorial With Affinity Photo" exported and processed with "AstroSharp by Deep Sky Detail" (AI shrpining) opened in Afffinity Photo for another curve adjustment and also applied "Shadow Stretch" and 60% "Enhance Structure" from James Ritson's "JR - Astrophotography V15 (16-bit)" free macro package. bortle 6, fair seeing equipment: C8 > IRc ut > Ds10c/imx294 Exos II PMC-8 mount
  2. Let's say you have some astrophotos, but with different exposure times. Such as 4 pictures with 900s each 15 pictures with 240s each 60 pictures with 60s each a proper set of calibration frames for each exposure length. This gives about an hour at each exposure level, but some pictures will have bright nebulas with stars burned out, and others won't. What is the recommended way of stacking these into a single image? Can I just add all of them into the same file group and Affinity Photo will figure out that these belong to different exposure lengths? Or should I use the file group feature for this? Another idea that came to mind is to first create three different images using the Astrophotography Stack Persona, i.e. one image for each exposure length, together with the corresponding calibration frames. Then use these images without Level and Curve Adjustments, and add them to the HDR persona, where Affinity Photo should be able to figure out that this is basically an HDR with 3 pictures at exposure levels -2, 0 and 2. I don't have the pictures yet, as I wanted to ask first before wasting my time in case Affinity Photo isn't able to combine these properly. Or is the general idea of an Astro-HDR already a bad idea in itself? Best regards
  3. Just bought and installed affinity-photo-2.1.1 and used it to do some layer masking and develop persona for curves VERY Nice! This was captured with an 8 inch SCT telescope in Calabassas, CA over a 2 hour period last month using a Sony IMX294 camera sensor, stacked with DSS. Info about M17 from https://en.wikipedia.org/wiki/Omega_Nebula
  4. RC-Astro StarXterminator and Affinity V2 Mac. I bought the product, but can not get it installed. When you do their Mac Install it loads on my hard drive, but AP does not see it. I have checked use Photoshop plugins (note, I do not have PS). Can sometime help me get this installed? Thanks
  5. 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 images (noise averaging - Greek letter Mu) to give about 4x improvement. For crescent images we might try stacking 25 images for an improvement of x5. I am trying to find a logical explanation for the green light over the craters. Regards, Jeremy.
  6. Attached is a document I created for simple astrophotography stacking, editing, and layering. Procedure to stack and edit astrophotography images using Affinity Photo 2.pdf
  7. I'm processing the publicly available raw images from the James Webb Space Telescope. The raw mono images are taken using different wavelength filters and by assigning different colours to each filter a full colour image produced. The problem I have is that some filters produce images that are half the size of others, so in order to overlay them they have to be stretched then aligned using 'Align Layers by Stars' but I am struggling to get the registration perfect. Is there a better way to stretch and align these images?
  8. Following the recipe of our own J.R., found here https://affinityspotlight.com/article/shooting-series-1-polaris-star-trails/ , I was happy to be able to come up with this result. Used here was a Canon 1100D, 50mm f1.8 lens, intervalometer (about 10 from our Chinese friends) set to 30s bulb and 10s pause. 50 photos made. Affinity really brought out some nice colors. Next time I will try better to center on Polaris and make 200 photos. Clear skies for all of us, Irving
  9. This image is a collage of the partial eclipse of the sun from 2022-10-25 combined with full moon from 2022-08-13 taken with identical gear (Canon EOS 80D, Sigma EF 150-600) at 600mm zoom level. It shows a perfect fit of the moon into the dark spot created by the moon a few weeks later. Of course, nobody will ever be able to see this image, as it combines (invisible) new moon with the 180° opposite full moon in one image. Unless Cameras with 32 or more f-stops / digital range will be available (estimated) Never the less, the outer edge of the moons eclipse imprint perfectly matches the full moon edge. and by coincidence, moon and sun have almost identical diameter when viewed from earth. That fact comes to surprise to me. Edited with fun in Affinity Photo. Raw development by Canon DPP as Affinity Photo is still no match.
  10. 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
  11. 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!
  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 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
  13. 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.
  14. 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.

  15. Using 1.10.4 OSX. Using the Astrophotography stacker Setting RAW Options: White balance: Master Flat Causes stacking to fail. Error: "Stacking Failed The images could not be aligned" Frames for LIGHT, DARK, DARK FLAT, and FLAT are being used. If the default "daylight" option is used, stacking succeeds. 2127446541_Nov32021.zip

  17. 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!
  18. 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
  19. 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.
  20. 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
  21. 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
  22. 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!
  23. 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
  24. 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
  25. 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
