Sun in Lunt50
Hello everyone,
Again, I'm a little late)) but a lot of work, and of course these days there is not a cloud in the sky.
Full disc from June 4th. There is nothing I can do about the unevenness of the pieces of the mosaic, no matter how hard I try, Fotomerge cannot bring the picture to a uniform tone.
I would still like to hear your comments and advice.
Happy viewing,
Ivan

Re: Sun in Lunt50
Excellent captures Ivan and I would say there is anything really wrong to worry about.
Could even be a little/thin cloud causing the unevenness...
Thanks for sharing

Nicely done, Ivan.
I struggle with the same issue on FD mosaics. It’s so difficult to get every pane perfectly even.

Re: Sun in Lunt50
Beautiful full disks Ivan!
Don't worry about the unevenness. Your FDs are very well made!
In case it may be of any help, when I tried my first FD, I worked it out by selecting roughly the uneven area by hand in Photoshop and then 'Select'-->Modify-->Feather-->Image-->Adjustments-->Level or Shadows and Highlights. The feather tool is all the magic!
Hope it helps.
Best wishes,
Alexandros

I wonder if GIMP has an equivalent?

I just opened GIMP and saw that under Select menu there is 'Feather...'. I suppose it is the same as in Photoshop, but have not used it yet. All the other actions I mentioned are available in GIMP. :-)

Though probably behind Photoshop somewhat in capability GIMP I feel comes in a close 2nd. And it's free of cost!
Thanks Alexandros.

Re: Sun in Lunt50
Thanks, James
I collected the last picture manually. Photoshop has always refused (at least for me) to collect a mosaic from proms.

I usually use the curves tool, but in the case of a mosaic, I cannot bring all the pieces to the same brightness level, although this should not be difficult. If initially everything is fine at first, then in ImPPG everything will appear again.
