Dear group,
My second result from last night which also involved four hours total exposure time (12x20min, H-a) involved the two dim and difficult nebulae IC 59 and IC 63 in Cassiopeia which lie within my 40' field of view. Owing to their very close proximity to the variable star gamma-Cas (mag 2.47!), the already dim nebulosity is difficult to tame and good contrast is most-difficult. The nebulosity at the bottom left is IC 59 (a reflection nebula) whereas the triangular nebulosity at the upper right is the emission nebula IC 63.
For a glimpse of last night's result, please see http://www.perseus.gr/Astro-DSO-IC-59-63.htm . The image is rotated 180 degrees with north being at the bottom so as to be compatible with third-party existing results. This result is also just a test (photon fix under non-ideal conditions) and will be revisited for an (Ha)RGB result when the moon out of the way.
A search on the internet yielded just a handful of results and which may be explained by the lack of contrast due to gamma-Cas.
Anthony.
