Detailed system information is as follows:

L Images: Borg 67FL+7870 reducer, f=210mm, F3.1

QHYCCD IC8300 Cooled monochrome CCD camera, -20 degrees

600sec x2 frames

RGB Images: Borg 55FL+7880 reducer, f=200mm F3.5

DSLR Canon Kiss X4 (IR modified), ISO1600

120sec x7 frames

Revision A: L image composite from cooled CCD

Revision B: First trial of LRGB composition

Revision C: color saturation enhanced, final revision
