Another easy catch for small scope users. I have seen this fan of nebulosity in binoculars (10x50's but better in my 15x70's) and even in my 40mm Cometron scope. This object does not respond well to UHC type filters but from memory, my Orion SkyGlow broadband filter coupled with my ex 76mm f/9 newt did do a good job on it. In larger scopes, it resembles the head of a comet with a slight fan shaped tail. The sketch below was done using David (westsky's) 10" GS dob from Leyburn although I have seen similar views in my C6 from dark sky sites.
