I think M57 is my "Waterloo". I never was happy with results last year
and this year I tried three times with even worse results. Each time
seeing goes to pot on me.

Your color looks good.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Thanks Rick, for this one i followed the advise of stefan to use the OIII
for both the green and the blue channel.
And i added a extra layer for the luminance channel.
Came out oke i think.

Nice vivid color and a good amount of signal for such short exposure time.
Like Rick, I have never got what I think is great data on this object and I
have lots of hours worth over the years... alonger FL and good seeing is
what shows this guy.
