Subject: [DarkSkyNewMexico] B 3 and 4
Barnard 3 and 4 are two dark nebulae on the border between Perseus and Taurus. This is a composite image that includes data from a smaller field around vdB19 and IC 348:
B3 is the smaller dark nebula while B4 is the larger expanse of dust across the lower part of the field. A little over 21 hours total exposure for the combined images.
Here is the image of vdB19 I posted a few months back:
