You sure he said f/11? I got pretty much the same FOV in my picture
(on the Observer's Challenge pages), but I needed a focal reducer for
f/6.3. Did he maybe stitch some images together?<br><br>

On Feb 19, 2010, Frank took this photo of the Cone Nebula and Christmas
Tree Cluster from his observatory in Gastonia, NC. He used a Meade 10”
LX200R, with a 2800mm focal length, at f/11. The exposure 40 minutes
using an SBIG STL-11000M camera. His mount is a Losmandy G11 with an
Ovision worm upgrade.<br>
