Need to sort out a more sensible way to decide if the prominences are 'real' or artifacts....

Some nice detail there, you could always check your image details against images on GONG. https://gong2.nso.edu/products/mainView/table.php?configFile=configs/mainView.cfg

Aye - but Gong is Ha....

Geoff,

Any CaK proms will also be visible in the H alpha images..

[Altocumulus]

For some reason I thought they'd be slightly different - though harder to see in Ca-K.

[Merlin66]

Definitely harder to image ( not a visual object) but similar to those seen in H alpha.

 

[Nigella Bryant]

Yeah, proms similar in ha and cak.

[Altocumulus]

Looking, again, at the original in impgg, I get the impression those proms are not real - perhaps something that crept in as I looked through Luminar settings!

I'll take a look at my ha image from yesterday and post later to compare.

[Nigella Bryant]

My image from 7th May 2020 to compare. North at top.

Thanks Nigella - that would point to mine being 'made up' through Luminar.

I've since tried to see if I can see any using ImPGG, but unsuccessful.

I messed up on Ha on the same day, so good to see the comparison.

ClearOutside gives me orange/red conditions for the next 6 days; but we'll see.....
