Cocoon neb 2.5 hrs with a DSLR...

[ngc891]

Hi, I've a wide field shot of the Cocoon area with 5, 8, & 10 min subs at iso 800 with a Canon 450D (home mod) totalling 2.5 hrs. All exposures were supposed to be 10 min but clouds had other ideas:P
Its processed with flats etc in DSS and PS.
Hope you like...

Nice Francis!
What focal length was the camera at?
Cheers

Bartman - sorry should have put more detail in description.
Scope is an Altair Astro 8-inch f4 - so 800 mm or about 31.5 inches and camera was cooled to about 12ºC below ambient with a home made chiller.

Hi Francis,

A great photo.
Nice detail and colours.

I am also impressed with your "home" modding and cooling.


Thanks.


Ross.
