Cooled Canon 6D, ISO 800, 0.86 "/pixel
(the Tak 1.6x only covers an APS-C chip on this scope, so with the full size
6D chip there is a lot of distortion around the field edge. The pic is slightly cropped.)
Air ~ 58 F, Camera ~ -8 C

North is to the right. Below is a B&W negative representation with some galaxies labeled.
The cluster of galaxies to the upper left (South East) is the Abell Cluster 347.

NGC 891 (negative image):
A few background field galaxies are identified.
Magnitudes are given without a decimal point.
Data from Sky Tools Pro 3.
I can find no identification for the background galaxy just
above 891 to the top right of it's disk.
I estimate this pic goes to about m = 19.
The Abell Galaxy Cluster # 347 is to the upper left (south east of 891).
