There is a secondary lens that I can see in the very end of the focuser tube. Also, the focuser tube does move smoothly throughout its range, from all the way in, to all the way out. There is an extension tube on the eye piece to accommodate the 1.25" lens. It is threaded onto another 1" Inner diameter piece which has a hole for a thumb screw to secure a lens. That is threaded directly onto the focusing tube which does not have a thumb screw hole, but is also a 1.25" I.D. I put the 25mm lens in that and had some good results so far. Unfortunately, I live in a fairly heavily wooded area, and can't get anything more than about a hundred yards off. I will see what happens later on but so far the results are promising. Thank you for the information!
Any other insights will be greatly appreciated.
Also, based on all that, is there anywhere I can go to find better accessories, such as shorter extension tubes, or different lenses? I knew going into this adventure there would be additional costs, and I knew this telescope wasn't exactly the best, but it was cheap (I am now at least its third owner, and I have no idea how old it is.) I've been looking at Amazon, and a few other sites for some replacement parts (I need to specifically replace one of the fine adjustment poles), but I don't really want to sink a bunch of money into a bunch of junk that will turn out to be useless for my needs, either in the short term, or in the future as my skills (hopefully) grow.
