Nice images, Ken. Lovely proms. I couldn’t capture any fine details on these yesterday because of the conditions.

Thanks everyone, appreciated!
The conditions are never perfect down here and I need to spend more time on my processing.

Nice images Ken! I have the ED80 too, you'll get noticeably sharper CaK images stopping it down to f10, at that scale it won't make any difference in lost detail either.

Thanks guys!
Mark,
Sorry I should have said, yes the ED80 is masked down to 60mm for the CaK.
