Scope/mount: C8/Vixen Super Polaris
Cameras: Vesta 675K SC3 BW and Vesta 690 SC3 Colour, using Mogg 0.6x focal
reducer. Captured with K3CCDTools: 75x40sec colour + 40x40sec b/w
No guiding, but using PEC (trained with webcam)
Image processing is simplified LRGB. Each capture was processed separately
in Registax2 and the end results combined in Photoshop, using the B/W imageĻ
as luminosity component.

The M27 image was shot using the b/w camera and a Mogg 0.6 reducer resulting
in approximately an f/6 system. I shot 23 frames at 15.8 seconds, and
stacked 20 of them, plus subtracted a stacked dark frame (processing in
K3CCDTools). Finally, some noise reduction in Neat Image and histogram
stretching and Photoshop. No artificial cooling was employed, as the cooling
power wasn't available and the ambient temperature was -3C at night (frost
on the ground).

All images below were shot with my old Vesta 675K SC1 camera (uncooled). Also, at this time,
I had no PEC to correct the tracking. The controller was a Vixen SD-1 and a single MT-1 RA motor.
