The Solar Chromosphere (Ca-K) - 10 Aug 2018 [UPDATED]

[David Smith]

Well, sort of. Far from conditions today with constantly shifting cirrus cloud - not good for shooting mosaics! Hence the FD is a little sub-par but the proms have come out ok. Don't seem to get many opportunities at the moment so need to take what I can get.

Nice one David. I have only had one Solar session this month. Clouds, clouds and yet more clouds.

David,

What's your typical exposure(s) for the CaK proms???

[David Smith]

Thanks for all the positive comments 

Not happy with the full disk mosaic I went back to the data today and managed to clean it up some. So here's the new FD set which I am much happier with.

 

@Merlin66 heres the exposure data from yesterdays prom run :-

Shutter=16.88ms
Gain=96 (18%)
Gamma=77

That is a very quite disc, thankfully at least there are few proms still around.
