One of the first attempts at using a "real" mount with tracking and guiding. Processing is minimal - rotation, cropping, removal of gradient light pollution noise, removal of green noise, histogram stretching, black balance.

Also visible is the effect of star trailing at the edges of the image. The telescope is used without a field flattener.
