Chintan Posted December 15, 2017 Posted December 15, 2017 I recently had the good fortune of capturing a few photos of the gemini meteors and I wished to combine all of them into one image. I have 11 that are useable. How can I merge them in affinity photo? Thank you Quote

John Rostron Posted December 15, 2017 Posted December 15, 2017 If your images have some recognizable background (that can be used for alignment), then: Load all the images into a stack (File > New Stack) and tick the Align box. Then select the maximum from the drop-down list (the default is median). This will allow the brightest pixels to show through.

IanSG Posted December 15, 2017 Posted December 15, 2017 I think the answer's going to depend on the pictures - you could try stacking them, but if you've got foreground objects they'll be stationary while the stars have moved (probably!). Cloning from multiple sources might work. Quote AP, AD & APub user, running Win10

Cloning from multiple sources might work. I was assuming that the stars would be faint in comparison with the meteor trails. If that were the case, then you could probably get rid of them with a bit of Curves work. I would agree that a few samples would help us help you.

No background unfortunately, I was pointing the camera upwards so it's only the sky 10 hours ago, HVDB Fotografie said: Are these RAW images or JPG ?

I have the raw and the JPEG files after processing them in rawtherapee JPEG files: https://drive.google.com/drive/folders/14q41kevTW1ovRQFiR0JVGGlVom0QWiQj?usp=sharing RAW files: https://drive.google.com/drive/folders/1oIoPXw941006-zjPoyL-HkoKXdw44nno?usp=sharing Quote
John Rostron Posted December 16, 2017 Posted December 16, 2017 I stacked the JPEG images and chose the Maximum option giving the image here: The stars do seem to have produced trails, and the meteor trails are (approximately) radiating from a common radiant. You should be able to align the images manually to improve the final image. Quote Windows 11, Affinity Photo 2.4.2 Designer 2.4.2 and Publisher 2.4.2 (mainly Photo).
