this is my first attempt at a color mosaic. this was a 2 x 1 mosaic of
ST10XME frames exposed through a set of Cust Sci 3nm FWHM filters and an AP
Traveller used with the AP 0.75x Telecompressor.

Each filter was exposed for 20 minutes at each site for a total of 2 hours
exposure. Since I had only one exposure at each site through each filter,
the image is noisier than I'd like
