NGC 7635 - Bubble Nebula in Cassiopeia

Dear group,

Last night I was privy to four hours of great transparency, great
seeing (FWHM ~1.7") and really stable temperature. I used the
opportunity to pursue the stunning Bubble Nebula in Cassiopeia. Two
additional hours of exposures had to be discarded due to high winds
and involved the one hour before and the one hour after my four-hour
window of pristine conditions.

The result from last night's effort is available at
http://www.perseus.gr/Astro-DSO-NGC-7635.htm and also includes the
best two exposures (10-min subs) from the two problematic hours used
as luminance.

For a glimpse of the result without these two additional luminance
subs and which is both smoother and richer, please see
http://www.astrovox.gr/forum/album_pic.php?pic_id=4543 .

I would love to hear which of the two versions you like the most.

Anthony.
