Looking to get a manual Alt/Az for a 102mm F/9.8 achromat. It's the OTA from a Celestron 102 GT. I'm going to gift it to a friend and his wife for their use. I wanted to get something simple, lightweight and easy to use, at the same time offer enough stability so as not to be frustratingly shaky. Both of these are currently "out of stock" just about everywhere I've looked, but there's no hurry. Would either of these be a good choice? Would one be more acceptable than the other. They appear to be pretty comparable in specs? I've looked at the Orion Versa 2, it seems like it's a little less stable, also has no 360 slow motion. Thanks in advance.
