I used siril to do a background extraction and then I tried stitching before stretching and it worked very well!! I then colour calibrated, removed stars from the 4 panel mosaic and stretched it from there. The only issue I had was a single panel didn't look as well integrated as the other 3. Assuming it's because I didn't have enough data as at this point I was doing a test (25 minutes per panel)
Nice one Martin, another brilliant video. If we every get some more regular clear nights I plan to have a go at my first mosaic so this will be useful to refer to. Cheers
Excellent Martin, one question I’ve tried this with. HA and Oiii image of the veil. But when build a new image in PS by putting them into their respective colour channels I find they don’t line up properly. Maybe as the crop from ICE wasn’t same size or something else ?? You didn’t touch on it in this video but how do you ensure all the NB channels align in your Mosaic ? Thanks
Thanks Chris. I recommend that you combine your NB channels into a colour image first for each pane of the mosaic. Then use ICE to mosaic the panes together. This should work OK.
Great video Martin - Thanks for taking the time to produce. I just downloaded the 64bit version for windows and it works a dream. However, I cannot get my screen to look the same as yours. For example telling ICE where to place images. My images are just stitched automatically.
Thanks Tony. I wonder if we have downloaded different versions of ICE? However, if it’s working automatically for you that’s great (it does not always work for me, probably due to the small overlap I use of 10%).
Mine automatically worked it. Hopefully I can find that option if not. Still surprised it worked unstretched. Then it's easier to do the stretching after. At least for a colour camera...

Excellent tutorial!
Thanks Chuck! Love your channel by the way….I’m a big SGPro fan just like you.
what a gorgeous mosaic!
Thanks!

Merci beaucoup Martin, ça va beaucoup m’aider à créer des mosaïques maintenant. J’adore !!!
Merci beaucoup Arnaud. Ciel Clair!
Perfect! I've been thinking of doing a mosaic for m31 with my 200pds, this explains it brilliantly. Thanks very much.
Great to hear that Chris! Thanks for the comment. Let me know how it goes.

Cheers Brian. I look forward to seeing the result!
