Thanks Greg,
If you're using the KAF-16803 then at those focal lengths your image scales are roughly 0.6" per pixel and 0.9" per pixel without and with the focal reducer respectively. As such, it makes sense to use it under your skies (you're on the border of over sampling). The very nice field of view (now over 1 degree with the reducer) is the real clincher.
I'd love to seem some test shots - simple star fields would be fine - to see the quality at the edge of that 1 degree FOV. A flat field would be interesting to see too.
Nice.
Paul
