NGC 7635 - Bubble Nebula in Cassiopeia

Dear friends,

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 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 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,
great work i think i like the second one better.

:shock:

Thats all I can say. Still cursing our skies here!

Wow what an image :shock: tried this myself the other night and er it was pants

OMG, !, me thinks you have tapped into the signal feed of the HST, :lol:
Seriously, a good A3 format book of all your images is what I want in my astro book library !

Anthony - the second appears better to me. But the diffraction spikes don't suit the image at all... A nice image all the same.
