If you've followed the Losmandy Gemini-2 beta progress, you'd know that a) finding objects with goto and b) long exposure guiding are no small miracles... I've been a patient beta user for months now.
Its a very nice image. I think there are a few small steps that could improve it though. Its got a bit of excess green in it. Try downloading HLVG from Rogelio Andrea for Photoshop plugin and it will probably enhance it. It needs a bit of cropping as there are stacking artifacts on the right side.
The golden glow of these stars could be enhanced a bit more to bring out that wonderful golden glow some of these images show. Louie has a good tutorial on how to enrich that side of the image.
