Re: Cooling Canon 450D

Hi guys! Digging this old thread up because I've decided to begin cooling of my 450D too. Any chance if you could share how you powered the cooling module? I'm thinking of using AC via a 12V adapter of some sort (perhaps cigarette lighter) but no idea if that would be safe...

Re: Planet Jupiter!

Half of me says that I've done it OK but I still feel quite clueless about whats going on. Would be grateful i...

Re: DSO imagery from Mersing

Wow!!! Stunning image of Eta Carinae there Ivan! Pity indeed there was a fair bit of haze in Mersing last weekend. I think I was more frustrated by its effects on my nose and lungs than on the sky hahaha
