  1. Hi folks, I wonder if a separate forum for AP astrophotography would be possible. I know astro must be a very small part of the AP business but it seems to me it should be easy to set up. I have thought of establishing a Facebook group myself, but I know so little that I would not feel comfortable as an administrator. AP is rather special having both the astro stacking and the editing. JR has given us to many good macros and tutorials. How about "Astrophotography Processing with Affinity Photo" as a title? I would be glad to hear your opinions. Thanks and regards, Irving
  2. Here is an example not being able to stack some Hubble files. I took the Oiii, Ha and red IR separately and stacked each separately. Then I saved each as a Tiff and stacked and alighned under "New Stack". The resulting pix file I edited as usual. Here is the result? Would be happy to have any comments. Got a server error -200 when trying to download. uploaded from handy photo. Thanks and regards, Irving
  3. Hi Folks, I have often had trouble (but not always) stacking Hubble images such as these belowIt would seem this should be a simple RGB stacking situation. Is there another way to do it with normal stacking, not astro? Thanks and regards, Irving
  4. Maybe a bit too much sharpness but I like it. Taken with 90x1250 Mak and Sony Nex 5N. Single shot no stacking, edited and sharpened with AP.
  5. Hi folks. I had trouble stacking 200 30s startrail photos so I took two parts (earliest and latest) of 100 tiffs each. I have stacked, merged visible and edited both. Now I want to copy and paste one on top the other, so as to combine them. After pasting I can line them up by adjusting the opacity but this does not give the result I want. Seems like I need to eliminate the background sky on one. But how? Help please with this. Thanks, Irving
  6. I did not expect anything but was just experimenting. It was set on median, same settings. What would you expect in this case? Thanks Irving
  7. Hi folks, I have taken 5 mountain shots on a tripod and wonder if stacking could improve the result. It seems it does not. A single frame is always sharpest. I have experienced this also with moon shots. Maybe with good lighting conditions this is always true. Could be different with very dim objects. Thanks for your help.
  8. Hi folks, I made a screenshot video of how to use Affinity Photo for making star trails, according to JR's instructions. Here it is on Youtube https://youtu.be/7jfDtxcYZ-A The result below was made with the same camera-intervalometer setup but using 200 30s shots with 5s pauses. Editing used adjustment layers for brightness-contrast, color selection and HSL.
  9. 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
  10. I made a mistake on the magnification. Probably about 400x according to an eyepiece projection calculator. Here is one of the photos edited.
  11. 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.
  12. Thanks for the replies. I was not very clear about my question to @James Ritson I would like to know if his macros are comprised of only the normal Affinity Photo commands. I have been unable to reproduce his M45 processing without his macros. Especially his colour separation macros seem very useful. The learning curve is starting to level off but I still expect some surprises. Thanks and regards, Irving
  13. Hello James, I have tried and tried to produce M45 results similar to yours without using your macros. Is it possible? I am amazed what the color (colour) separation does. I am not able to achieve such results without your macros. Have you ever published details on your macros? Thanks and regards, Irving
