This was shot half at 1800mm f/9 and half at 3600mm f/18. (Ridiculously oversampled for the seeing.) ~50 frames @ 90 seconds and ISO1600

Nice detail. Sounds like color camera?

Hi
Can you explain the rationale behind shooting half the frames at 1800mm anf half at 3800mm focal lengths?
Thanks
Francois

Nice shot Mike. Perfect focus and tracking. I thought my opportunities to image were limited, but up there in Alaska the nights must be getting awfully short..

Mike,
That's a really cool image. It gives me some ideas about what I can try on this object.
