Hi guys.

Here's a couple of images of that huge sunspot ar798 erupting solar flares and causing those beautiful aurora. Taken on Sep 10, at approx 10am AEST.

Details:
- 10" dob on EQ platform
- ToUcam @ 10fps
- FL: 1250mm (newt prime focus). Seeing was not good enough to barlow.
- Seeing: 5.5/10
- Each image is a single frame, processed in photoshop.

Comments welcome.

Hi Paul, thanks for the comment.

Thanks again.

Iceman, this kind of work is one of the more neglected areas of IMPORTANT amateur science. I commend you for perfecting a technique which may prove to be absolutely vital to our future should satellite disruption (due to major solar storms) and electrical blackouts (I wonder if you could give a suggestion to a Polaroid fan- me?) greatly retard the gathering of information about our Sun. I too have a 10" Dobsonian reflector but wish I could get detail from polaroid shots (no batteries, no photo shop nec.). Would paper screen photos of exit light from lens be my only way? Thanks for your splendid and inspiring photos, I can hardly believe the detail!
