IC 1795, also know as the Fish Head Nebula, is area of new star formation with glowing gas and dart dust, in the constellation of Cassiopeia.  This is actually a portion of the larger Heart Nebula (IC 1805) complex that is located about 6000 light years from earth. Since my scope cannot fit the entire Heart Nebula into its field of view, I opted to frame the Fish Head portion of the nebula.  I framed it using the Mosaic Planning tool in SGP and had SGP dial it in using the Pegasus Astro Falcon Rotator. 

 

This shot was taken over two nights  (November 12th & 14th) with a narrowband setup, and is the result of ~5 hours of total integration.  I would have liked to get another couple of nights data on this target, but I feel pretty fortunate to have gotten two nights of data collection during the month of November in Upstate NY!  I can only get about 3 hours of data a night due to trees on my property.  The second evening was cut short as a bank of clouds moved in around midnight.

 

The image was processed into the SHO Hubble Palette.

Thanks for looking!
