M57 - distinct colour

FINALLY, we got some clear night combined with an ever shortening day.
I managed to get my first night's decent observing session in months. However, first thing that struck me was how much I had forgotten! Out of practice I guess!

I took a peak at several DSOs but one that stuck me in particular was M57. I've seen it countless times, but tonight I tried as low a magnification as I could. This made the ring appear smaller and brighter. With this, it took on a really clear and obvious colour - a sort of bluey-green. Close to turquoise I guess. Very obvious to my eye anyway. However, when you increase the magnification. the nebula becomes more diffuse and the colour fades away.

Anyone else noticed this strong level of colour at low mag on M57?

Cann't say I have but I am quite colour blind so that may explain why!

Michael,
Must be those fab nagler eyepieces providing a great contrast, this might be why your seeing this...
I haven't had a chance to see anything since the transit, I'm just too busy.

Contrast is increased at lower mags, so maybe colour is concentrated also, since your positioning the light from the nebula into a smaller area.

Did you see this in the meade eyepieces ??

I was using my 32mm Meade super plossl which gave a mag of 62x.
The colour becomes clear when you compare the colour of M57 to that of the nearby stars. It's then that it strikes you.
