I considered shooting M57 on April 8. Clouds rolled after one six-minute frame with the SXVF-H9C through the ED80. Here is that one frame. This is about as bright as M57 looks in a small scope, but there are two differences: (1) this image has more color than a small scope would show, particularly in the nebula itself; and (2) there is a hint in the middle of the nebula of its central star. This is a pretty dim star. It shows up much better in this earlier black and white image taken with a larger scope and for a little bit longer total exposure time. It is over-exposed in this much deeper image.

Not bad for an 80mm - very surprising! Will have to give that a shot, maybe.
Cheers,
