IC59 - IC60 - Gamma Cassiopiea
with 10" f/3.9 Astrograph / MiniCat 51 Context
Uploaded 11/31/25
Two images to share here today, taken last month. One is with the primary instrument - a 10 inch Newtonian and the second
is the field Context image taken with a Williams Optics MiniCat 51 Petzval. The 10" shot reveals not only the two butterfly wing
shaped nebulas clearly but an enveloping glowing cloud of hydrogen which even includes Gamma itself. In fact, the entire
field is glowing with loads of red and pink hydrogen gas.
The MiniCat image which has 5x the field is a simultaneous context shot which shows the full extent of the swirls of hydrogen
in this area. A huge wreath of nebulosity encircles Gamma, and extends in small patches over the whole field. Note the
indicated very obscure planetary nebula Bohm-Vitense 5-2 to the upper right, something I had no idea was there but thats
exactly why context shots are taken! The third image Ive labeled an obscure planetary nebula (nebula around dead star) BMV 5-2
which I had no idea existed and was found in the edge of the context shot.
