Had a lot of fun with these - how often is poor seeing absolutely essential to your imaging, and the poorer the better?

Took an AVI last week of Sirius at low altitude in poor seeing, flashing extraordinary colours. NexImage through 4.5" f8 reflector & 2x Barlow, de-focused slightly to avoid burn-outs and to emphasise colours.

First image is a composite of 30 images, cropped and re-sized from 30 consecutive frames taken at 30fps. So this represents changes in the appearance of Sirius over an elapsed time of just ONE SECOND!

Second is the same 30 frames made up as a border, consecutive clockwise from top left. The middle is a widefield centred on Sirius, taken the next night with Canon 400D at 55mm.

I suppose we all have too do something to fill in the time between good seeing

Nice colours

Good one Rob

Sirius was really scintillating last week with the high temperatures, the seeing was terrible.

You have presented excellent examples of the colour changes that occur over a short time when Sirius is low in the sky. :thumbsup:

Cheers mate

Very cool Rob :) A novel employment of scintillation. :thumbsup:

What an excellent way to demonstrate the concept.
