but none of my eyepieces would focus :S
please help
its a perfect night tonight and im missing it
If you're viewing straight through without the diagonal, you'll need to use an extension tube.
Do you have a barlow lens? Unscrew the glass from the bottom and put somewhere safe, and use the barlows tube as your extension.
Otherwise just put your diagonal back in.
Unless you are viewing the neighbours, you will soon want to use that diagonal anyway, it is called "refractors neck" LOL. Try it for a night without, especially at the zenith, you'll get the idea.
