Hi,
I've had these three panels for over a month. Tried stitching them together in DSS, didn't work. Also tried Canon photo stitch, it worked but the background was unbalanced.
I ended up downloading ICE by microsoft, worked beautifully!
Thanks to Allan Gould for that recommendation.
I think the reason it was difficult to get right was orion was high in the sky, while taurus was dipping down to the northern horizon giving a fair gradient in the background.
Jupiter in shot, also created a problem being so bright. There was a lot of reflection in the lens, it's all balanced out quite well with some fiddling in PS.
HEQ Pro 5 mount.
Unmodded canon 1100D nifty fifty lens at f/4.5.
2 minute subs at iso 800, total 16 minutes for each panel, darks frames applied.
Median stack in
DSS, stitched in ICE processed in
PS 7.
Cropped image.
Cheers,
Justin.
