hi my friends,
it's been a while since my last post.
weather was nasty for more than 2 months.
but - everything ends and so does bad weather...
I started M76 in an almost perfect night! 1.11.07 - we had terrific seeing and transpareny. (8)-9/10 !
but that night moon came up high in the sky so I had to stop after 2 hours - it was just too bright.
then of course - I had to wait a little ... and on friday last week I was able to complete the session with 5.5 more hours of exp time.
single frames 10 minutes and 15 minutes.
scope: 9" f/9 TMB Apo
CCD: SXVF M25C one shot color
image acquisition, autoguiding preprocesing astroart4.
also CCD sharp and registax for preprocessing.
postprocessing (incuding pseudoluminance) in PS CS2 and Pix Insight LE.
here we are with a small preview:

make sure to check out his enlarged crop HERE:

this little nebula holds only some 61 ar seconds in its longitudinal axis and therefore is a "hard nut" in terms of resolution and detail.
I am really very glad with that result, as the central appears to be a little elongated and one could get the idea, it has two parts...(only visible in the enlarged crop)well, I admit - this is personal bias here...
also the small stargroup was a specific target and I am happy, the 9" apo split this group.
looking forward for your comments and tips, guys!
