Bushnell 800x70 Regractior Voyager

I just got the telescope shown in the subject of this post. I can site a planet just fine in the sky. However, I am having a terrible time trying to focus the telescope. Even with everything locked down, when I turn the adjustor knob, the planet is bumped out of view. Am I doing something wrong?

Hi

Not sure if I understand the problem, but, first, what magnification are you using? Too much magnification puts a strain on both the optics and the mount. If you're using much more than 120-140x on a small scope such as this, you are pushing both the optics and the mount. At these magnifications, yes, simply touching the focuser can bump the planet out of the field of view. Try to keep the magnification down if you can.

The other problem with observing planets is observing conditions. You need a steady atmosphere for observing planets and that aspect of the atmosphere can change from night to night and even hour by hour. Once again, magnification compounds the problem. Too much magnification just turns images to mush on an unsteady night.

Try dropping the magnification and also try viewing on different nights and see if this helps. Good luck.
