Thanks for looking everybody.
Glad you liked them.
I was totally stunned with the Horse Head. What I saw on the monitor was a few stars and a vague sort of shadowy spot. Who would have though that THAT would be the end result.
Star bloom is a big problem when you push this camera to it's limits. I should really lower the integration rate and capture more images to compensate. Next time maybe.
Mike, Matt explained about the in camera frame integration.
As for RB's comment, well, I forgot to post the images with the message.
