Dear forum, I'm contacting you because I need a repair. I work in an amateur astronomical observatory in Italy, very active in asteroid astrometry. Yesterday our rolling shutter on our SBIG STX16803 stopped working. I opened the camera and there was a small crack on the mechanism. I just touched it and it broke (see enclosed photo). So I need a replacement. It will be better if this shutter could be replaced with a mechanical one (not rolling). Is it possible? Moreover the ccd chamber must be dried. We purchased this camera in 2015 from an observatory in Illinois (Bob Holmes, Astronomical Research Institute). I enclosed the label of the camera. Thank you and best regards, Luca Buzzi Schiaparelli Astronomical Observatory Varese, Italy www.astrogeo.va.it
