Look into the past 2.0



Ruins of the ancient cretan city of Itanos ( Ίτανος) in front of the Milky Way.



This is a second attempt at photos taken in 2022.



The Milky Way was photographed with an integration time of 38 x 8s = 5m 4s and processed with #Siril, #GraXpert, #StarNet and #GIMP. The ruins were taken with 30s exposure and light painted with a flashlight, then processed with #RawTherapee and GIMP. Final composition was done in GIMP.



Milky Way: Nikon D500, Tokina AT-X 11-20 f2.8 PRO DX, 11 mm, f2.8, 38x8s, ISO 3200, tripod

Ruins: Nikon D500, Tokina AT-X 11-20 f2.8 PRO DX, 11 mm, f2.8, 30s, ISO 800, tripod, light painted

Comet C/2025 A6 (Lemmon) (bottom of the image) and Gemma (main star in the constellation Corona Borealis) (top of the image) on 24 October at 20:33 CEST from Wedemark, north of Hanover, Germany.

The straight, bluish plasma tail is visible over a length of ~6° (12 full moon diameters). The curved dust tail is a lot shorter.

Crop from a stack of 51 2-second images at ISO 5000, f/2.8, and f=200 mm.

Comet C/2025 A6 (Lemmon) on 24 Oktober at 20:28 CEST from Wedemark north of Hannover, Germany.

Cropped from a stack of 51 single exposures of 2 s at ISO 5000 and at f=200 mm.

Used Siril, Gimp, and NeatImage to improve stacked image afterwards.

Edit: Added newly edited version of the image with less color shift added.

If there's someone here doing #astrophotography with #siril , there's something I can't do: I'd like to export a whole sequence as a MP4 . I've found the option alright, but I need to apply a stretch first (I've tried, I get an all black video otherwise). How can I apply the same processing to a whole sequence and save it as a new sequence? I can't export as FIT or TIFF because I don't have enough disk space, and image magick doesn't read fit.fz :(
