Subimages RGB: 9/11/11 x 900 sec (2.25/2.75/2.75 hrs)

So that's 11 hours as opposed to your 8.2 hours.

You have a 12" with 2438 focal length.
Eric has a 20" at 3420 focal length.

I did some quick maths which may be wrong.
I estimate Eric has twice the depth.

I notice Eric has posted here - good one.

cheers
