I really like this picture as it shows it in context with the surrounding stars etc. What exposure did you use David? Was the camera mounted on your 'scope or a tripod? Sarah

Hi Sarah. The camera was mounted on my telescope using a Whitworth thread screw, to connect one of the mounting rings to a standard pan and tilt head. Exposure 20” f6.3, ISO 800. 85mm setting on zoom . more to come

Final image only a 1/7 of full frame so I could have used a longer focus lens. Used moon to set focus using auto setting then switched to manual for imaging. David
