My good friend David Ho, owner of Hotech, has posted some YouTube videos on how to collimate your Cassegrain telescope.
You can find links to the videos on Davids Facebook page here. Please help David out by liking his page when you stop by for the video links.
If you have ever had any difficultly collimating your telescope, David’s instructions will help a lot.
David also sell products to help you collimate a variety of telescopes on his website (http://www.hotechusa.com). I own a couple of David’s inventions and they have made short work of a previously long and arduous process. My stars are pinpoint and the resolution is great. Now if he would only invent that cloud removal filter everything would be great!
