Wayne, your piccies should be in the deep sky section, not here. They're really good pics

The Nex 3 and 5 cameras are amazing. I've seen pics taken with them before and for such short subs the pics you get are amazing. It's like you've spent hours taking 10 min subs, when in actual fact you've only used 15-30 sec subs.
Did you have any troubles with your camera overheating? Did you use a T mount and adapter tube for your camera. Which ones did you use?
