Mosaic of IC1805 Complex in Cassiopeia

This rich but faint nebular complex resides about 6 NW of h Persei and 5 NNE of Double Cluster in Perseus (see finder chart below). The largest and very diffuse part of it, IC1805, contains large and bright star cluster Melotte 15 at its center. Other star clusters (NGC1027, Berkeley 65 and Markarian 6 are located around its edges. The brightest part of IC1805 Complex consists of nebulae IC1795 and NGC896 which together form a compact "blob" intersected by narrow NW to SE streaks od dust. All those objects are identified below:

The mosaic above was assembled from 24 tiles composed of 120 images taken on October 9, 1999 from Sooke, B.C. with Celestron Ultima 8 SCT at f3.0 and Cookbook 245 LDC CCD camera. For each tile, five 60 sec. exposures were taken through infrared blocking filter and then combined with Multi245.

The above image is reduced to 30% of the original. North is up. IC1848 nebula is located just SE off the above field.

Map created in Guide 7.0 - 745' x 10. North is up.
