Re: Importance of the image restoration in the solar imaging.

This is great Valery, however how do you stack your images? I have taken some lovely videos through the C11 and my eye can see all the detail but once I stack in ASK3 the image is a complete blur and nothing can be salvaged from the stack.

Re: animation on our star on October 16th

It is always a joy to watch animations of prominences. No matter how hard I look I can never see the plasma moving up, always down, so where does the plasma come from if it is always down :)

International Astronomy Show - November

I was just wondering if anyone was going?

Not sure whether to go or not yet. Always nice to meet people if they are going as it makes the day more interesting. So I am undecided at the moment.

Strehl ratio for a Celestron C11

Does anyone have a graph of the Strehl ratio for a Celestron C11 at 393nm for full aperture and stopped down in 1 inch steps? Just interested to know when it hits 0.9

I would say that neg2 is far more on band than zero (which doesn't look very nice - sorry). I would try negative 3, 4 and 5 next.
