Since taking possession of a new to me AGO 12.5" iDK in late December I've had maybe 4 clear nights that all came around a bright moon and had terrible seeing conditions.  One of those nights was dedicated to tuning the scope and my camera.  Three of those moonlit nights I captured two nebula, large PN Jones Emberson 1 (the headphone nebula) and the relatively rare NGC2371 (the Gemini or peanut nebula).  

 

Both of these are bicolor Ha/OIII images.  I'm not particularly proud of either given the seeing conditions so these were basically a warm up for galaxy season which I'm really looking forward to this year.  However, NGC2371 definitely deserves a better look next year.

Why do they call it a peanut nebula? Looks more like saltwater taffy to me.

My guess is that visually it looks two lobed like a peanut.  Images reveal more structure.
