Was this during the day or at night time?
Remember - you need to be in focus. This involves two things:
- Having the correct back focus for your setup (are you using a reducer/flattener with this?).
- Making sure the OTA/Telescope is in focus.
So I recommend trying to get a daytime focus (late afternoon). Remember - don't point it at the sun. It'll ruin your optics unless you have the right filters on (and potentially your eyes, too, if you're using an eyepiece or finder scope).
For daytime focus you want to look at something at least 500m away (the corner of a roof, an electricity pole, etc).
Sometimes you may find you are turning that focusing knob for a while until you start to see a blur, that then becomes a blurry image, and then finally comes into focus.
Also remember: let's say you are using something such as the ASIAIR. You'll want to put it into Video Mode and turn the exposure way down (since you're doing a daytime focus).
