Thank you! This is really good lens (04B I mean), even if it was not part of "SP" line.

Fresh (brand new) batteries could help. On mine with some older batteries I have no problem with modern lenses or lenses with A-contacts, but with older M-series lenses it happens. M-lenses are close to t-rings as they have no contacts on lens base at all.

SP 23A (60 -300) on K-7. First one closer to the long end, second one around 70 mm.

BTW, I realised that I need one more P-KA mount. To my surprise there are (almost) any Adaptall listings in the marketplace. Maybe one of the Members here has one spare for sale?

Thank you! No, chromatism is almost not visible. I wanted this one (70 mm model) instead of 90 mm one, hoping that even if it will resolve less it will have no abberation at all. It seems to be the case. Celestron Astromaster 70 has f 12.9 but Q seems to doesn't know that it is so far in diffraction zone - photos seems quite OK.

Genuine Q on Celestron Astromaster - 70 (900 mm) - stacked from 3 images, cropped. I'm sure much better results are possible with this setup.

FA 28-70/4 is not the aviation lens usually, but I had today the biggest plane of the world behind my windows, so it turned out OK.

I have no problem at all to focus using standard C/PQ adapter plus C-1,25 in my Newtonian. It is not true for all my other cameras, but for Q it works. I'm just putting the eyepiece cap on the eyepiece adapter when not used.

Not the best photo, but clearly great camera for travel! I used my Q on the go at the airport while running (almost) for a meeting.

It is nice lens - maybe not super sharp and contrasty, but I found it usable for nightscapes/starscapes (infinity photos) wide open on APS-C. Seems to be better for this sort of images compared to it's modern incarnations.

You can always resell 18-50 here if 17-50 works for you.

I always planned to get M150. And, looking at the photos, you prove it is a good idea. How do you like it?

Now I can rationalize not getting M150 little bit as I have M 75-150, which is nice also, but...
