Comet Tuttle and M33

Hi all
Here it is. As I was setting up Alan brought round Hoghys cooled camera and lightbox (thanks fellas), for some thermal noise free imaging. The northern sky was VERY bright with the air moist, low cloud to the south tyhankfully little to the north.
First pic is 12x2 mins ISO200
2nd is 7x2mins ISO800 with UHC-S filter. It cuts down the galaxy but lets comet light through.

Both taken with the 300mm f2.8 lens from Bert, and Houghys cooled DSLR. Sensor temp 7 degrees. Processed in Iris and photoshop.
