Sunspot 905 - Brisbane 23 August 2006 11:02am

Hello,

Well, hot on the heels of Sunspot 904 is….Sunspot 905. Once more, seeing conditions were somewhat challenging today. Here is an image from this morning, 23rd August at 11:20am. It consists of only 2 frames.

I manually selected these best two frames, 448 and 449, from an 1800 frame avi and then stitched them together in Corel Photo Paint 12 to produce this final image. It is quite “thin” so doesn’t stand up to any further processing.

Celestron C9.25, Astrozap full aperture Baader solar film filter, Vixen x2 Barlow.
Philips ToUcam 840K. 5fps, 1/250 sec.
Acquired in K3CCDTools. Frames selected in Virtual Dub.
Brisbane, Qld, Australia. 11:02am AEST (GMT+10)

Cheers

Dennis

EDIT: I managed to find another 2 decent frames on an avi from later in the morning, so this 2nd image is a stack of 4.

Nice one Dennis.

If this is any indication then we could be in for a long hard solar maximum over the next 5 years. We're still technically coming out of the minumum

Great image of the Sunspot 905 !!!!

Good job Dennis

Thanks guys. This one got me into a little bother. I was meant to be re-sheeting the eaves and painting but I couldn't resist climbing down the ladder and grabbing a few avi's.

Delayed the job which was noticed and frowned upon!

Cheers

Dennis

Hey Dennis, these are beautiful to behold

You've really captured some great granular detail as well as the spots on this big hot orangy thing

Hi Dennis,

excellent capture.

Thanks guys. The jet stream whipping across the top of Brissie is making things a little difficult. Registax will not produce a decent image as no 2 images stack nicely, so I have been reduced to using Registax to create a stack list of the best images, then I grab the good ones with Virtual Dub and save them as bit maps.

If I run through 3 or 4 avi's of 1800 frames each, and manage to get maybe 4 useable frames, Registax will then produce a reasonable image. Its' a bit slow mind you, but what else can I do whilst the paint is drying under the eaves.

Cheers

Dennis
