Solar mosaic in H-a 071111

[Photosbykev]

one from today, the first session in ages!

Taken with a PST and DMK41 ccd camera on an EQ3 mount, guided using DSSR software to automatically create the mosaic.

The DSSR software is now available as a public Beta, highly recommended ! window_sill_observatory : The Window Sill Observatory

and colourised in PS

Wow that is stunning Kev!

It makes me want a PST all the more

Stunning pictures!!!

That software sounds very interesting, I took a full disc yesterday and I have found much to my annoyance I have missed a chunk from the bottom.

and a few proms and sunspots

Magnificent images. You might consider decreasing the gamma a bit to give them a more 3d look.

Thank Cschur I'll have a play with the gamma in the camera next time I get out

I've been asked a question on a photo site, which was "Do sunspots comes as pairs?" with reference to the single sunspot at about 19:30 on the main image above.

Any thoughts?

Excellent pictures, a joy to look through!

Active regions can have any number of spots within the group. There is a classification system called the MacIntosh classification 1990SoPh..125..251M Page 253

P253 is of most interest, you can get unipolar groups.

Glad to see you're still getting some sun in Kev, your images are getting better than ever! Sun is in the rooftops for me atm which is a bit of a pain - roll on spring!

I am running out of sun time with the surrounding buildings. So I think early next year I will be cutting the PST in half and going for a PST mod scope. I just need to figure out what the best donor scope is for increased aperture and focal length.
