07.17.21 Sun in Lunt50

Post by Ivan »

Hello everyone,

Mosaic of 6 fragments.

Only now I was able to process the material filmed on July 17th. The conditions were not the worst, but it happens even better :) The main headache during processing, in addition to the fragments of different tone, was Newton's rings, which for some reason (this happens to me rarely) decided to appear on the left lower and middle fragments. This isn't the best FD's, so sorry.

I would be glad to hear your feedback and criticism.

Thanks for watching this. Full resolution is available if you open the picture in a new window.

Ivan

Thanks for sharing

The details are absolutely fabulous :bow :hamster:
I wonder, are the NRs worse when slightly off band? this disc is slightly more off band than usual and I was wondering if perhaps the NRs were more apparent because of this. Just a thought ;)

Hi Alexandra,

Thanks for your feedback. Your comments and advice are very important to me. Could you decipher what NR means?

On this day, I re-tuned the tuner, because it seemed to me that it gives a too uneven picture, I check this by making longer exposures.

After tuning it seemed to me that it got better and I did not think that I had left the strip. Although if you look at the area around AR, then it is too contrasting, while the rest of the areas are less contrasting. But it seemed to me that this was due to the difference in visibility, which changed during the filming.

Hi Ivan,

NRs = Newton's Rings
