The Sun 11 Februrary 2012 white light

[Bizibilder]

After quite a delay, some Sun images! There were even moments of pretty good seeing today for a change. The AR close-ups were stacked using AutoStakkert as an experiment - the software seems to have made a good job of the stack. I used Registax5 for wavelets. An R5 stack of the same .avi did not produce nearly as much detail in the final image with exactly the same wavelets. The downside is that AutoStakkert takes about 15+ mins to stack an .avi that stacks in less than two mins with Registax - . It was set to stack the best 10% of images for each of about 200 regions of interest. The full discs were 64 frames stacked in R5 and finished in PS CS5.

Very good catch!!

Well done!

(we're still under cloud here in Belgium!)

And a picture taken as a stack of 64 frames using a #58 green filter:

Amazing!!

Great job!

Just reprocessed AR 1416 in REgistax % and PS CS5 only. Seems that using best 90% cut-off in R5 has helped - I usually use 80% - 85% to keep the noise down - this resulted in a stack of 220 out of 2400 frames.

Top shots Biz!

Beautiful images! and thanks for letting me know that the new version is out. I've been asking Emil for a while when this new version would be out as he has been getting excellent solar pictures with it since this time last year but wouldn't release it. I must go and try it out on my WL images from last year.

Thanks for the Autostakkert warning, just downloaded it and it's brilliant! However, on my file it processed a 600MB file in 3 minutes, about 4 x quicker than Registax 6? and it has done a 100x better job, I am so happy!

I think it may depend on the number of alignment points used? On my avi's it was using around 200+ which is probably why it took so long.

Superb Which camera did you use to capture these? Just posted my pathetic attempt - wondering now why I bothered Clearly I have much to learn and a long way to go I didn't know you could get so much surface detail without a special solar scope.

Fantastic images

For the full disc the camera was a Canon 1000D at prime focus of a SW Evostar 120mm achromat stopped to 100mm with a Baader Solar Filter. Images shown are with and without a 2" #58 green filter which i'm experimenting with. I generally take 64 JPEG frames and stack them in Registax 5.

For the spot close-ups I use a SPC900 webcam, 1200 frames per .avi (sometimes 2400 frames). Again with the green filter.

Thanks

Just to add, I find Autostakkert runs slower on my lappy than avistack, however, knowing me I probably have stoopid settings set up on autostakkert, with a bit of time will tweak and report back...

The green filter image is amazing!!! Well done!

A fantastic set of images! I really enjoy looking at images of the full disk as it gives an idea of the scale - and just how big those sunspots must be.

Great shots there. Nice capture of granulation!
