M57 with ST-7E and Meade RGB

I just got some meade RGBL filters for my St-7. The easiest object I know of is M57. I have done it in the past with my MEADE Dsi-C but wanted to try my ST-7. There are 9-3min images for each filter(RGB), no L. I have no wheel or filter slide yet and my have mixed up the B and G filters. I plan on checking the next chance I get.

Hi Eric,
I don't consider this to be an easy object, but you have done a nice job on it. Keep the images coming.

Nice Image Eric.

Ty is right, M57 can be a challenge. It does look like the star colors seem to be biased a bit toward Magenta. I don't know if mixing up green and blue produces that result though.
