Caldwell 11 Bubble Nebula

Mark Griffith

Swindon, Wiltshire. UK

Celestron c11 sct, skywatcher NEQ6 pro mount, Canon Eos 1100d self-modified and Astronomik CLS CCD clip filter.

Fifth attempt to image this nebula. Finally solved my flexure problems. My guide scope was not attached securely to the main scope. It was a bit loose.

20 five minute & 6 six minute light frames at iso1600. 20 dark, bias and flats. Deep sky Stacker and Gimp. Cropped to 2420 x 1440 pixels.
