IC446, 447, NGC2245, 2247, 2264, others - 2x2 mosaic - LRG

[Roberto]

Hello All

Attached is a 2x2 mosaic in Monoceros that took a month to complete over the New Year period.   The beautiful blue nebula IC446 contains at least two van den Bergh reflection nebulae on its own.  It and the surrounding objects are part of a huge star forming region designated RSF3 Mon which lies some 2400 ly from us (https://adsabs.harvard.edu/full/1988SvA....32..484S).
There are several NGC and IC objects all around the wide field OSC shot including, in the lower corner, the Christmas Tree Cluster and Cone Nebula.
Total exposure was just over 42 hours.

A great image Roberto, you also have a bit of the Christmas tree nebula in the FOV as well.

Strange that there seems to be 2 catalogue numbers for this reflection nebula.  Both IC447 and IC2169/

Thank you Carole!  I think IC447 contains IC2169 (and some vdB objects also).
