Hi,
Wide field pic of Eta Carina nebula.
Pentax 200mm lens @f4, iso800, 10x30 second exps.
Stacked in ImagesPlus then rough bit of processing in PS.

Been trying to use examples and theory in "Photoshop Astronomy" by R. Scott Ireland - but I gave up and did my own thing on this one!!!

Cheers
Doug

UPLOADED SAME IMAGE MINUS CA AND STAR SIZE REDUCED TO BRING OUT THE NEB' - CHEERS

Thanks Eric,
Agreed - quite a struggle to pull detail out of the noise with this one!

Mike,
The camera (Pentax ist-D) was mounted on a motorised EQ4.

Nice round stars. If you haven't done so you should be able to easily remove noise in the image by subtracting a dark frame in photoshop via Image -> Apply Image -> select dark frame image and subtraction method.

Top work Doug......hope its okay but Ive attached your image with it run through photoshop to reduce the colour fringing using a plugin that I got to help with my widefeilds/camera lenses { astronomy tools }
