Received the item in good condition and it fits or works good. it will be a good addition to my telescope picture taking set.

I ordered one of these with my 900mm (Bell & Howell) mirror lens. The mirror lens sucked for IQ, but I kept the ring as it appeared to work without sticking. These adapters can be used for adapting your Pentax body to spotting scopes, telescopes, and microscopes. Since it was relatively inexpensive, I kept it even though I returned the well built but inferior image producing mirror lens it was intended for.Honestly, there doesn't seem to be an affordable solution to acquire that kind of reach with decent IQ.

The rings are well made , however they do not fit the Pentax X90 but then again no one does. If you file the fine treads off, you can get it to slide onto the X90's Lens, This is the only way I have found to use the X90 with a telescope.

Inexpensive, generally well-machined, no moving parts or electronics. This adapter does exactly what it needs to do; it adapts your Pentax K-mount to t-threads usually used to attach your camera to your telescope's focuser for prime-focus astrophotography. I've been pleased with the fit and finish. If you're getting this to place your camera on a Newtonian reflector, please note that you will need another adapter from t-threads to 2" and more in-focus than most arrangements allow for. You can use a barlow lens to achieve focus, however.

It allows my Pentax K1000 camera and my Rokinon 500mm mirror lens to work together. Well machined, nice tight fit.OK, my distance scale is about 90 degrees of to the right, but that's what the 3 set screws (hex screws) are for, to make the needed adjustment. Yea, it's actually 2 pieces held together by the set / adjustment screws.

Pretty cheap. Fits my Pentax K-3 to my Celestron PowerSeeker 127EQ telescope. I've taken some photos of the moon using it. I'm looking for some nice weather to take shots of other things. It's nice being able to hook my camera up and take photos.
