Hi folks.
I have a SkyWatcher newtonian 200mm and I have been trying to use my Celestron Omni 2x barlow; however, when I look at planets (Saturn for instance) the image at the eyepiece is hard to focus. In fact, it stays fuzzy at the best focus I can achieve. I think it does better on nebulae and deeper sky stuff, but I am unsure if this really is the case...too many clouds lately to test this on a range of objects. Oh, yeah, I'm not trying to go too high in power - I've been using my 25mm, 12mm and 10mm EPs...
Any thoughts?
