I spent about 20 minutes wondering why I couldn't achieve focus with the EOS 600D and Sky-Watcher Dob until I realised I hadn't extended the flex tube all the way. With sunrise approaching and seeing even pooerr for Saturn I chose Mars as the subject. Here it is at 4:33am AEST.
Hi Dave, yes they do - no barlows required. The dslr attaches with perfect focus just on its own.
Too right Justin - no matter how many times I've used this setup something silly like that can still throw me. Like the time The images I was getting were so dark and I couldn't figure out why so I packed everything up then to find the main dust cap on with the small off-axis cap off. Or the other time I simply could not find Jupiter because the finder scope cap was on - only discovered after everything was packed up again.
