I've got two nice 1.25" Chinese KE's that I'd like to trade for one good quality 1.25" ocular, or perhaps a nebular filter.
These Kellner's have 25 and 10mm focal lengths and are in very good contidion. Coated glass is practically perfect, but the barrels have typical set screw marks from years of loving use. Both are threaded and include original boxes and plastic bags - they never came with caps. These would be great for star parties, or for a young person's telescope. Typical or better Kellner optics.
If you're interested please make me an offer. I'd like something around 10-16mm, but I will consider other focal lengths. The glass has to be in excellent condition and I need lots of eye relief because I prefer to wear glasses when observing (astigmatism). If you're offering a filter, then surprise me.
