combined 9 exposures. Fieldsize = 12.2 x 18.1 degree (note: Moon is about 0.5 degree). Tracked with a small telescope. IC 4665 is an open starcluster, M14 and NGC 6366 are globular clusters, the labeled stars are part of the constellation Ophiuchus (Schlangenträger). Also given is the picture of 252P/Linear I made a week ago. The line that is visible is a passing satelite.

All these features, but for the Hyades, were visible with the naked eye. Photographically I needed three different exposures to bring out the details, as a bonus I got the Hyades ISO 400 f/4 f=200, mm, t=1/8 sec ISO 200, f/4, f=93 mm, t=2 sec ISO 200, f/4, f=93 mm, t=8 sec
