Hi - I tried a simple two panel mosaic on Christmas Eve of M45 in LRGB. I'm following Mabula's sticky'd multi-part mosaic tutorial. One obvious difference is that I am working in monochrome whereas the tutorial data is OSC.
I've spent a bunch of time using light pollution tool on my first integration panel (luminance). Now I'm wondering whether I should be combining data before running the light pollution tool??
Background calibration doesn't work on monochrome data, right?
@tbar23 As for light pollution reduction, it really depends on your data. If one mono channel shows a lot more light pollution than the others, you may want to apply it only to that channel. If your data are really nice, you may not need to apply it at all.
Thanks both. @Wouter-Moderator - that makes sense. If, for instance, my luminance data was all taken in the hour or so following sunset then, perhaps, it would require more light correction to another channel if taken later at night pointed in a direction with less (or different) light pollution.
In my case, my composite image showed a bit of odd coloration, and I suspect that could be due to individually correcting each filter differently. I may try combining the data into RGB before LPC (and also look without any).
Thanks.
