Alexandra,
I have a SM60 DS on an ED80 and a CaK filter stack on an ED80 stopped down to f10.
Unfortunately the seeing down here at the coast is pretty average.

Thanks everyone, appreciated!

The poor seeing at the coast and my lack of processing skills limits the detail....
I also notice that the CaK image shows much better detail towards the top of the image and appears "off-band" at the bottom.
I can only assume misalignment of the internal filters???
Any comment?

Good job, ken. That is 2 days in a row. This active region is worth tracking. I got it on 3 and 4 Oct. Unfortunately I couldn't do it today (5 Oct).

Alfred,
We were clouded out on the 4th, got a couple of images through high cloud on the 5th, and today started overcast but high winds cleared the cloud but stopped play!!!!
