Hi all, I have been pretty quiet on the images lately due to cloud cover, commitments, the flu and full moons.
Last night I got a great night in with crystal clear skies, no moon and nice and cold. (7degrees). I was rugged up so much I couldn't move much, but the camera loved the colder air.
May I present to you, a target I havent tried before. This is Messier 83, The Southern Pinwheel Galaxy, located east of the constellation Centaurus.
This image was 34 minutes exposure at ISO 1600. Subs were two minutes each, stacked with darks, flats and offsets in deep sky stacker.
Image taken with an unmodified Canon EOS 400D DSLR camera, through a Celestron Nexstar 11 GPS telescope, fitted with an F/6.3 Focal reducer.
Selected guide star manually tracked, using a piggybacked Skywatcher ED80 telescope fitted with a modified Phillips ToUCam Pro II 840K Webcam.
More cold weather coming, I cant wait to get below zero!!!!
Cheers,
Baz.

nice M83 barry. I think you've clipped the blue channels however as it is abit too red . keep it up , you are doing a great job at it.

Its the filter (standard) in the Canon mate. I really need to do the mod on the 400D. Cooling and dedicated filter.

That aside, I am still pretty pleased with this image. I have left the scope and camera in exactly the same position for the next available night. I will collect more subs and add them then.
