M77, in the lower right of the
image, is a face-on spiral galaxy located about 60 million light-years from our solar
system. It is an example of a Seyfert galaxy with an active nucleus, and is a fairly
bright object that can be seen in small telescopes. Large telescopes are required to see
the spiral arms. NGC 1055 is an edge-on spiral galaxy that is part of the same group as

Exposure: LRGB: L 8 x 5 minutes, binned 1x1: R 8 x 5 minutes:
G 8 x 5 minutes: B 8 x 5 minutes: RGB binned 2x2

Location: Landers, California, USA
Technical Notes: Exposures were dithered using CCDAutoPilot2 and
then sigma combined. The RGB images were combined in Registar 1.0. Unsharp Mask was
selectively applied to the brightest portions of the luminance image at 100% with a radius
of 1 pixel and a threshold of 0. A Gaussian Blur of 1 pixel was applied to the dim
portions of the luminance image and to the RGB image.
