Large Prom 25 Oct 2007

[rumples riot]

Thought I would take a quick peak at sol today; not expecting very much.

Well this is what greeted me. Lovely prom.

Hope it gets bigger overnight. More likely will collapse though.

It was a lovely treat.

That's a ripper, Paul.

Night capture

The surface looks nice too

Very nicely done Paul..... What scope is this using??

[erick (Eric)]

Powerful stuff, Paul! Thanks. I like seeing it with the surface also showing. I've seen other representations that just show the limb with the surface dark.

Lee the scope is a solarmax 60.

Eric, sometimes the seeing is a little nicer than at other times. When it is a little nicer I like to take the surface detail too. In better seeing the spicules would be obvious. When the seeing is worse, it is better not to include disk detail.

Thanks guys for the comments.

Lovely image, nice work.

[Alchemy (Clive)]

very nice ... how big (kilometres high) would that be.

[h0ughy (David)]

Paul so you found the banding problem? Nice image!!

[rumples riot]

Al I figure the height of that prom is about 24,000 to 36,000 km high and about 48,000 wide. A drop in the ocean really on a disk that is 1.39million across.

Houghy, I know what the problem is, I have to use a flat field to get rid of it now. Except when imaging on the limb. It does not show up as much. I found that it is hardly noticable with the 2x barlow, but becomes really evident as I go up in image scale. This was taken with the 5x powermate, but the banding did not show up much. I can still see them, but only just.

wow
