ASTRO: First light in color: M33 now with flats from Christmas Eve

must have just missed Santa.....

Definitely have the twinkling multi-colored blinky lights in this one....
the 400mm lens has a bit of star bloat. I think a UV cut filter will take
care of that

I shot this on Christmas Eve from the Ranch out near Hornitos/Mariposa
California in the Sierra Gold Country.

it is 3 hours 25 minutes total exposure. I used a Pentax 400mm f/4 camera
lens. This was first light for it. It is made for the 6x7 camera and it is
HUGE and very heavy.

I had to re-engineer my lens support mechanism for a third time to handle
this beast and I still have a bit more work to do to completely stablize it
irrespective of the sky angle where it is aimed,
