H-Alpha Sun & Proms 12/1/12

[Star Catcher]

Hi All

Got a small window of opportunity to get some imaging in last Thursday morning before the strong winds kicked in again. Several connected proms made a nice view and a neat fantail prom on the far right of the disk.

Seeing conditions started to deteriorate midway in the imaging, so the detail is a bit iffy and inconsistent on one side of the disk as this is a two panel mosaic.

The image is here: H-Alpha Sun with Some Proms (http://zoom.it/cScd)

Using LS8OTha and DMK41 with 2X barlow. Hope you like it.

Bloody hell, I have serious scope envy!

Please post some more!

[DJVege]

Agreed!

What Poita said! :)

Thanks guys. Even I keep thinking whether I should have spent the money and got the bigger LS100Tha? Although the LS80Tha is so portable and can easily be run on a manfrotto. Maybe down the track :)

Nice pic Ted glad your getting a little sun

[Star Catcher]

Thanks Derek. A "little bit" is as good as it gets lately. Yesterday I was reduced to trying to gets some solar imaging done at 5.30pm in between the clouds!

Hi Ted
A stunning image - excellent stuff and thanks for the view!

[Star Catcher]

Thanks Matt. Yes it came up well after I hit the data with some heavy duty image crunching.

Top shelf stuff Ted, I'd worry about the seeing well before another 20mm of aperture. :thumbsup:

Great shot!
Are you recording the surface and proms with the one exposure?
I usually have to use different exposures for the surface (1/80s) and longer exposures (1/11s) for the proms with my double stack SM60..

[Star Catcher]

Thanks Peter, you are probably right. I am no where near maximing out the 80mm.

Hi, no I used a two exposure composite for each of 2 panels for the mosaic. At this stage I am tending to stick with single stack as it minimises the uneveness in exposure for the sun surface. Thanks.
