UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Before I release it, I will make sure that everything is working properly and then I will release it.
I have some banding with the mosaics I have been trying, it isn't terrible and a lot of people can't see it but I know it is there and if I push the stretch too far it shows up.
50- 3 minute lights each panel
Master dark, flat and dark flat applied
BPM applied
2 panel mosaic
MBB set to 10% (sames as my overlap)
using lnc 1st degree with 5 iterations
Set to mosaic mode
It prompts me to check same camera and optics (just now looking at this it doesn't appear to be checked though)
Dynamic Distortion checked
Scale stop of 10
Not sure if it's the compression, but the star field itself looks a bit strange, did you post process it in some way?
@vincent-mod
Yes, I typically do post processing in PS CC, I don't think I've ever just taken what comes out of APP.
In PS I usually stretch it more, do contrast and saturation enhancements as well as noise reduction, sharpness and clarity.
And does the banding show up in APP or after the post processing? Just to be sure I can maybe pinpoint it more. I personally do think the noise reduction might be a bit too high as the stars aren't nicely round anymore if you look closely.
@vincent-mod
Yes, it is present in APP, if I increase the strength of the stretch you can see it.
@vincent-mod
I bet I had a couple of bad subs in the stack. On a related note is there a free tool that works like blink in PI? Will APP come out with a quick cycle preview tool?
I'm not sure about the exact release path, but it is on the list to be implemented if I'm not mistaken. I usually don't use it and just stack based on quality and 90% of all frames. APP then automatically rejects most if not all of my problematic subs.
Regarding the banding, I can't really tell either and would need the original data. You can share it on Mabula's server if you want and I can have a closer look at it (in a few days as I'm moving in between).
If I open your image and stretch it you can see some kind of border between the 2 images. This border runs from just right of the middle (horizontally) from the top to just left of the middle on the bottom, like annotated in the screenshot below, am I right?
I think the image on the right side of the mosaic was not processed right with the light pollution tool, there's some gradient left behind.
I did not edit these separately but stacked, stitched and edited them as a whole, so the edits should have been done to the whole image.
I think I tweaked a few of the settings and started getting some better results. I plan on adding some more data to this in the next few days so I'll see how it all goes together. Thanks for the reply!
Maybe it's better practice to stack and process them separately and after that stitch them together in APP. That way you don't have to worry about gradients if you use the light pollution removal tool.
I'm working on a 3-pane mosaic at this moment and got very good results with no visible borders whatsoever.
I'll definitely be trying different things once I have enough data for a "final" image, I appreciate your insight.
Hopefully by next week I'll throw up another attempt on here to compare it to.
