July 31st - H Alpha - Prominences not Prominent!

[paulastro]

An early morning start, completely clear and I had to wait for the sun to rise.  The impressive prominences from yesterday have largely gone.  There were some very faint proms but by over-exposing on 1/2 sec exposure I did manage to bring them out - but visually they were hardly visible.  Single frames with Lunt 60 DS and Olympus E-M10 at 500 asa.  The first taken at 6.42 am (the sun doesn't rise into view until 6.35) on 1/80 sec, the second at 6.47 am on 1/2 sec.

Good early catch Paul, cloud here but should clear a bit soon hopefully.

The filament is still looking good though!

Glad you got another shot Paul.  Proms often show up better in single stack, their bandwidth is often greater than the smaller bandwidth of a double stack scope.

Thanks Peter.  In fact if you look to the S at the filament below which is much fainter is actually quite a bit longer!  It is much fainter though and more disjointed, though I'd still think of it as a single long filament.

Many thanks Robin, number 44, though I think tomorrow's weather is going to bring it all to a shuddering halt.  Yes, I'm aware of the prominences looking fainter in a DS system.  I suppose I should make this clearer when talking about prominences, for which my terms of reference always refer to using a double stack system.  Though I'm aware I'd get a better view of them by removing the front etalon, I never do as I have it all adjusted, clocked to the best positon and 'locked' in the best position, so I almost never remove the front etalon.
