Popular Post +Derbyshire Dave Posted August 24, 2022 Popular Post Share Posted August 24, 2022 It's been a long time coming this one! Two panels on the Pelican and North America nebulae, with a 20% overlap. Final image is big enough to allow that Pelican to breathe. 12 hours of data on each half. This is the longest I have taken on any image. ZWO 183mm mono camera, William Optics GT81 scope, ZWO narrowband Ha,Oiii and Sii filters. Stacked in PixInight, aligned in Photoshop (as PixInsight wouldn't play ball). Finished off in Photoshop with a luminance layer from the Ha Click and click again in Flick for full resolution Carastro, Bob Dobber, philjay and 10 others 13 Link to comment Share on other sites More sharing options...
Bob Dobber Posted August 24, 2022 Share Posted August 24, 2022 Nice! I'm wrestling with mosaics too, one Q - did you stitch before aligning and processing? It seems a bit off - if you stitched first before combining channels that might be the reason? Looks really promising though, great detail and a nice SHO palette 🙂 +Derbyshire Dave and Clive 2 Link to comment Share on other sites More sharing options...

I am far from being an expert, and haven't succeeded in stiching mine together yet as a finished mosaic but that was suggested to me. I was just worried I would process the panels to a different degree and then find they were nastily patchy, but just not had time to revisit. Looks like you've got great data which is a big help!

It's always going to be hard, I was worried about processing the two haves differently too. Link to comment Share on other sites More sharing options...
Bob Dobber Posted August 24, 2022 Share Posted August 24, 2022 What are you using for stitching? ICE seems to be a reasonably good tool for the job but I've not revisited it other than in purely Ha. Link to comment Share on other sites More sharing options...

I do sometimes use ICE, but this time I used Photomerge in Photoshop Bob Dobber 1 Link to comment Share on other sites More sharing options...
