Emission Nebula NGC1491 in Perseus

(RA 4h 03.4m , Dec. +51°19', 25 x 25 arcmin.)

This emissiom nebula is located about 6°25' NEE of a Persei or 1° NNW of l Persei (see finder chart below). Its listed size seems way too generous - 4 x 4 arcmin. is probably more real.

Telescope was autoguided with Cookbook 211 LDC camera on a piggybacked 500mm f8 telephoto lens. Seven white exposures (120 sec. each) were combined inAIP4WIN.
