M57 is fun... this thing is so bright I want to try imaging it at f/18 on the TEC200.

Here is M57 unguided, with only 2 exposures of 90" for each of RGB.

If this is possible in under 4 minutes per channel, I think spending a couple hours on it with the FFC for f/18 would probably be amazing.

Looks good Mike,especially for 4 minutes per channel.

This sucker is small but very bright!
I remember the first time I found it visually, with an 80mm refractor it sticks out like a sore thumb.

This one is certainly on my list to re-do. There are lots of galaxies in the background if you go really deep. It looks like you barely snagged one at the top.
