B 3 and 4

Gregg Ruppel

Hi all:

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:

Clear skies,
