Swindon, Wiltshire. UK
Celestron c11 sct, skywatcher NEQ6 pro mount, Canon Eos 1100d self-modified and Astronomik CLS CCD clip filter.
Tricky target to image. Magnitude two star Alnitak was causing large reflection doughnuts with my focal reducer and IR filter. I got round this problem by positioning Alnitak just off the camera chip. Only managed 7 frames before this bright star drifted back onto the chip.
7 five minute light frames at iso1600. 20 dark, bias and flats. Deep sky Stacker and Gimp. Cropped and reduced by 72% to get image size below 2MB.
