9Hrs 30Mins Exposure Of the Pacman Nebula

Hi All,
Here is an image I took of the Pacman Nebula. With the Moon being so bright I thought I was wasting my time imaging but what the hell It was clear so I started imaging 18.20 stopped at 05.15am and I ended up with a 560Min exposure not bad for a nights work.

Another fine image Carl.

You could have saved yourself some sleep though. I was doing a few calcs on your signal to noise gain for this extended imaging run and from frame 60 to 112 you increased the signal to noise by just under 4%. Have a look here to see what I mean starizona.com/acb/ccd/advtheoryexp.aspx

Hi Kieran,

Another great shot Carl.
Just one question...
Where are you getting all the clear skies!!!?? It has been a complete washout down here.

Hi John,

Thanks for the reply. We were lucky with the weather the other night to be honest I just took advantage of it.

Your lucky you weren't out on the beer those nights Carl! A truly beautiful image.
