IC 1805 HSTPosted By Maciej Kapkowski |
IC 1805 "Heart nebula" seems to be nice for narrowband imaging. Responding well in both S II and O III bandwidths.
There are also two others on this picture : part of IC 1848 "Soul nebula" -upper right corner as well as Melotte 15 in the center. Melotte 15 is an open cluster with nebulosity. Its 50 l.y.closer to us than IC 1805 itself.
Warsaw, April 2011.
S II: Ha: O III- 6:9:6 h. Ha used as a luminance.
FSQ 106N, STL-11k, EM-11.Chip temperature -35 C.
Enjoy!
