This was one of my first eyepieces back in 1991. Bought it based on a rec from the first edition of "Backyard Astronomer's Guide" by D&D. It didn't work well with my f/4.5 Odyssey 10. I hung onto it because it worked really well when used in combination with my TV 1.8x Barlow, for a 9mm equivalent, serving up a view pretty close to a 9mm Type 1 Nagler that my observing buddy had.

I think the 16 Konig works better in f/10 inch scopes like SC's.

I never got around to selling or trading mine although it sees little use these days. I keep it partly for sentimental reasons and as a conversation piece.

Do you still own one, and how often does it get time in your focuser?

I still have mine. I think I bought it sometime in the 80's. Have not used it for at least 5 years.

I just pulled it out of storage because of this thread and will try it again. I think the reason I have not been using it is the tight eye relief.

I use them on occasion, usually as a grab-n-go set with my 80mm f/6.9 refractor in conjunction with a 2.8x Klee barlow. It offers a wide magnification range and as they are "normal" sized eyepieces, they fit in pockets nicely. I took the set out this evening with my Intes 150mm f/12 Mak to check out Jupiter after reading this thread. What a fine view. The 12mm gave about 150x in this scope and it was the best observing of Jupiter I have had this season. The planet was crisp to the edge with the 12mm requiring a little focus adjustment occasionally. These eyepieces matched up very nice with this focal length scope yielding magnifications of 75x, 113x, & 150x. I may have to compare them to some plössls or orthos as another planetary option...

Yes, and yes. Use it either my 6" f/8 newt or one of my small Maks. got mine in the mid-1980's.

With only four elements the Konig gives very nice planetary views....on axis. Off axis in faster scopes can be less satisfying.
