Description

This is the result of an excercise with the humble equipment i had at the time. To track the sky I used an old EQ mount by Towa with wooden tripod motorized with its clock drive. The telescope was stopped at f/9 using its cap in order to limit its wild chromatic aberrations.

Exposure time was limited by tracking accuracy so i raised up the ISO to 1600. The light pollution posed a limit on the shadows details. In this condition the dynamic range of this sensor has proved large enough to preserve highlights and to reveal some structure of the nebula.

No dark/bias/flat was used for the final image, only alignment and averaging in DSS.
