Description:
I found easily M 78 star-hopping from Alnitak. It's easy to see with all 
powers but 80x gives the best view. The rather bright nebula surrounds two 
small 10th magnitude stars. The nebula has roundish shape but elongated 
towards south-east, with a sharp northern limit and a fuzzy south part.  
15' north from M 78 is located another nebula, NGC 2071, very faint and barely 
seen around a mag. 9 star; at the limits this telescope.  
A very interesting pair of nebulae.
