This is a mosaic of 2 images, each of 0.1 seconds The images were taken with a Alta-U9 attached to an Meade RCX400 12" F/7.29 telescope. Each of the images was corrected with a dark frame and a flat field.

A DSI Pro was atttached to an ETX-90 for guiding.

A Hydrogen Alpha filter was use to reduce the amount of light getting to the U9.
