Popular Post Joe Posted October 31, 2019 Popular Post Share Posted October 31, 2019 (edited) Ive been working on the california nebula in HaRGB as a 6 pane mosaic, and I have just finished capturing and processing the RGB. I wasn't expecting to get any details so to have to have all this dark dust, nebulosity and galaxies show up is very promising... This is my first proper go at Mono RGB imaging, and doing a mosaic. 9h total exposure 1.5h per pane, 30 min per channel 540 x 1 min exposures @ Gain 75, Offset 15 ZWO ASI1600MM-Pro William Optics Star 71-ii Astronomik Deep Sky RGB Filters Bortle 5/6 higher res: https://joesastrophoto.myportfolio.com/the-california-nebula-in-rgb Now just to add 20h of ha 😅 Edited October 31, 2019 by Joe higher res +RonC, Bassinghamobservatory, +Ibbo and 3 others 6 Link to comment Share on other sites More sharing options...

+Derbyshire Dave Posted November 1, 2019 Share Posted November 1, 2019 Really excellent Joe, a great job. Lovely handling of the colour, and well done for the planning and persistence to bring this off. What software did you use to stitch the images? You’ve made a good job of it Joe 1 Link to comment Share on other sites More sharing options...
Joe Posted November 1, 2019 Author Share Posted November 1, 2019 I used Microsoft image composite editor or ICE. its pretty good at what it does but I would not suggest it for such a large mosaic like this. The max I'd do is 2x2. It's just hard to get the accuracy in the stars. Chucks astrophotography did a video on it once that's pretty good: He starts with how he captured the individual images, then he shows how he used ICE +RonC 1 Link to comment Share on other sites More sharing options...
+Derbyshire Dave Posted November 1, 2019 Share Posted November 1, 2019 Hi Joe, Thanks Joe, I've had a quick look, looks interesting, I'll download it and give it a try. I've recently started using Sequence Generator Pro, which has a mosaic wizard, which will generate the requisite overlaps. Assuming that a series of stacked images are created for the mosaic, do you stack them before stretching, or after? Thanks Dave Joe 1 Link to comment Share on other sites More sharing options...

Im not too sure. If you have gradients in your images like I did or the stars are not very bright like in a narrowband image, I would stitch them after stretching.Just make sure your background brightness and colour levels are the same. I think doing mosaics in narrowband is easier due to less gradients but i've never done one. Link to comment Share on other sites More sharing options...
