| Seeing was about 2/5 on
this night, which is average for Payson. This means I could just
barely use the 5x powermate with the 10 inch, the trick here
was to use only the best 25 frames out of 1200 taken to keep
the images sharp as possible at a reasonably low noise level.
The DMK51 I used here has the lowest ambient noise in the industry,
and is perfect for planetary and lunar shots.|
