A couple of nights ago I went out for the Perseids. I didn’t have much luck shooting them, but I got a couple of nice milky way shots. I’d like to share this one, in which I captured the trail of a UFO that reminded me of an awesome Japanese cartoon/comic of my childhood
I tried to do the stitching with hugin but I failed miserably. So I had to do it by hand in GIMP. The result is not perfect but more than enough for me. Basic development in RT, and then to GIMP+G’MIC for various tweaks (besides the stitching).
I am constantly in awe at the wonderful images you astro people capture. Thanks for sharing this! I’m looking forward to playing with this myself when I get a free moment!
@agriggio Alberto, I was able to to stitch your images with Hugin.
What I did:
export 16-bit tiffs from your raw files using RT (neutral profile plus noise reduction, profiled lens correction, Amaze+VNG4 demosaicing) DSC09066.ARW.pp3 (10.3 KB)
in Hugin : CPfind then fine-tune for the control points, masking out the foreground in the 2nd image, auto optimization for positions (incremental, starting from anchor) and low dynamic range photometric optimization, and then using the Trans Mercator projection, saved as TIF. DSC09066 - DSC09069.pto (7.5 KB)
open the sticthed image in RT for further processing, trying to use some of the settings from your PP3 (but on the tiff, it doesn’t give the same thing) :
Preprocessed in RawTherapee four frames. Two stitches made with Microsoft ICE, one of the upper two frames and one of the lower two frames. The two stitches were combined by gradient mask in Gimp.
