Missing focus knob on a Ext-70! #5649174 - 01/28/13 08:21 PM
Hey guys, I'm new to telescopes and astronomy but I find it fascinating and would like to explore it further. I heard that there was going to be a full moon over the weekend so I thought it would be a good idea to take my sisters old telescope out for spin since she is away at college. While trying to view the moon I noticed that it was missing the focus knob, so I could see the moon but it was all blurry. I can't find the knob in her room and I was just wondering if there was a website I could buy another knob from, of if there was any way I could make a makeshift knob.
