Nice one Marc. I need to try this sometime. I always stitch my Mosaics in APP as its so easy to do. I know the new WBPP is hugely improved so want to use it more. Clear skies
The previous way I used to stitch mosaics using the star alignment tool was a bit of a faff but this way is so much quicker. Thanks to Russell’s video it really helped me speed up the process.
Thanks for showing us your workflow, Marc. I learned a good deal from seeing how you brought up a so-so image to something quite presentable - there are several steps there I want to try out. Your approach to working on the non-linear image is quite different to most RUclips video presenters, and it may well get me around several problems I have been finding. Also, I'd like a bit more understanding of the Pixelmath/s expressions, so I will go hunting to see what I can find. Yet again, you have stimulated me to improve my skills. Great video - I'm going to see what other pearls you have!
Thanks again Christopher and that’s great to hear you have been encouraged with your skills. PixelMath is an odd beast and to be honest I don’t think there’s a lot out there. I started digging into it a while back and it feels a lot like getting a programming language, understanding parts of the syntax but not really knowing what to do next. I should be able to learn it as I used to do software development. 🙈 I was going to do a video on star and starless combination but that’s down the list at the moment.
@@astrojourneyuk I've done my share of coding in my misspent youth, but the coding instructions for PixelMath(s) (you can see that I'm not North American!) eludes me probably because I haven't yet decided to put the effort into learning it, and simple addition and multiplication seem to do most/all that I want at the moment. BTW: I use Flat-Darks with all my imaging with ZWO cameras, 183 and 294. It seems to work quite well. A Kiwi RUclips presenter covered this for the 294 in ruclips.net/video/nl_LQDmkg2o/видео.html which, apparently has been getting some flack for its amp glow characteristics. I would recommend that you do this and see if you get an improvement.
Thanks for the flat darks link. Ironically since I found out what I need to do for the asi183 I haven’t used it because it’s been galaxy season. 😂 I’m with you on PixelMath(s) as well, half the battle is knowing what you might need to do to then write the expressions.
@@astrojourneyuk It's my pleasure, Marc - I hope that link helped explain things. BTW: I noticed that when I applied the EZSoftStretch script, the stuffing went out of my stars (a good old Australian expression would be "stonkered" my stars, but you don't hear that word anymore). I was able to extract them and recover a good bit of their brilliance with CurvesTransformation, and thankfully, I didn't see any artifacts arising from this. Do you have any thoughts on the cause of this? One thing suggests itself to me: the centre of my mosaic is a small triangle of nothing where my frames weren't overlapping enough! Maybe pure black is influencing EZSS - it's just a thought. (I tried twiddling the settings, but nothing seemed to improve the result.)
A good question! In all honesty I'd forgotten about its release in November 2022! :( I'll definitely be using it in future. Previously I used to do manual colour calibration so the photometric approach is a benefit over that one. Thank you for raising the point for others to see.
@@astrojourneyuk I thought that using WBPP takes care of the image registration and astronomical solution. When I run WBPP I do not need to run Image solver. I just use a preview sample to provide SPCC with the coordinates.
That’s right, so if you don’t use WBPP and use something like DeepSkyStacker you’ll need to use ImageSolver however WBPP uses ImageSolver in its script.
This guy is top notch, really interesting and clearly knows what he is talking about. 😊
Thanks Dad! 😀

Really nice result! CS!
Thank you. Would have been better if it weren’t for that pesky amp glow. Time to sort out the calibration files.

Any reason you did not use SPCC ?

So if you used SPCC instead would you still need to run image solver?
Yes, you do still need to have a plate solved image for this to work.
