Description

A mosaic of 2 images. The top was done with a #29 Deep Red Filter. The bottom with no filter. These were done with a Sony Nex-5 non- modified camera and a 45mm Minolta lens. This camera was piggybacked on a 1983 B&L Criterion 4000 for tracking. These are captured with a memory card and an external intervalometer for shutter control.

The Red filtered data was not in good focus but usable. This caused the other subs to not be in focus also.
