Cocoon Nebula

[Miguel1983]

Hi,

clear night yesterday, so i moved the scope outside to attempt a image of the cocoon nebula witch is currently arround the zenith position.

I was planning on taking 35 3min subs, but when i checked my status after an hour i noticed my laptop had run out of power (did't plug it in) so i only got 12 subs.

So made the best of what i had and i used calibration frames from previous sessions.

 

Cheers

For 36 minutes of data, I think you have the basis of a great result there. More data is definitely the way to go.

As regards the calibration frames, a standard set of bias subs (or a standard master-bias) is fine, but (if you are using the Canon in your signature) I'm not sure that darks from a previous session will help a lot, as it is does not have set-point cooling and flats will only be of benefit if the equipment is exactly the same as the previous session (including orientation & focus).

Nice one, you can clealy see B168 as well. I had the chance to observe this object recently, it was quite tricky to find, but managed in the end by following the dark cigar to its end.

Great job with the data available. Excellent background and stars.
