Default M57: Ring Nebula in H-alpha + Luminance

Hi all,

I hope you'll like this new image of the nebula M57 obtained from two
different
series of shots in H-Alpha and luminance.

http://www.danilopivato.com/tabulae_...m57_brc_ha.htm

With three minutes of exposure to frame luminance was possible to capture
about 40
faint galaxies all clustered in an area of 16'x16 'centered on M57.

Of these faint galaxies could not find the name and magnitude with the
exception
of IC 1296.
On the map I have, however, reported their position and apparent shape:

Kind regards,

Default M57: Ring Nebula in H-alpha + Luminance

To: Danilo Pivato
This is one of the best images of M57 obtained from a ground based telescope
that I have seen. I am just starting out in astrophotography with my humble
Meade DSI II and have taken some images of this also, but no where near this
good. I am learning to use exposures effectively, and will be stopping by your
web site frequently for tips.

Cheers!
