Zeiss APQ’s are wonderful instruments.  The first time I  looked through and focused the finder, unmounted, I begin to appreciated the optical-mechanical excellence which it exudes.  Love the helical focus, and this 1993 built APQ100/1000 (Strehl 97.7)  is as nice an instrument as I have ever owned or observed with.  

 

Here with a Q . . . A fun combination

It's a nice site. For this particular lens test the author does identify it as a Zeiss Telementor. Most of the tests he does not probably to avoid being free brand advertisement or criticism. In one test the scope is described as a 101 mm f/5.4 Petzval not to hard to figure out who the manufacturer is:)

As well as a 102 /500  = (my) ST102 from Skywatcher.. by the way de-centered and over corrected... but "useful for low deep sky observing and no morefrown.gif

 

At least, i have the Zeiss...smile.gif

Can someone please tell me that visually AS scopes are as sharp
as APQs. I really don’t want to buy one of those as well.my marriage is on the rocks and I think buying one will seal the deal 🤝. At least the scope won’t run off you with another one. Lol.

The AS'es are just as sharp as the APQs. Happy now?

 

The contrast in the APQs is better, though, especially on very low contrast objects.

Thanks Thomas your advise has saved me a lot of legal fees. I’ll just avoid low contrast objects and be happy with my scope and wife. 👍😁

One thing I came to strongly appreciate last night is the modularity of the Zeiss telescopes. I have suddenly developed a strong pain in my lower back and setting my 152mm APM up is out of the question at the moment. And naturally, it suddenly cleared up shortly after sunset, though it was quite windy... 

 

But because it's so super easy to take the Zeiss 1b, tripod and telescope apart and put them back together in seconds, I could still get out and observe a little, though it was quite painful at times. 

 

 

Clear skies!

It seems to me that these -itis threads, due to their popularity, should become topic threads in the "Telescope Specific" forum.  More accurately called brand specific.   

 

I got my first Zeiss telescope this past year a 3x12.  Not good for astronomy but great for museum exhibits sign reading and as a hand lense.  At close focus it's magnification increases. It works as a tripler in some eye pieces but of course dims the view too much.

Just found this thread today: https://forum.astron...mont-ic.278577/

 

It almost made me weep. Look at what we lost, when they closed shop in 1995. An autoguiding Zeiss mount, for flip's sake. And that image of the Rosette at the end of the thread, through the APQ100/1000 on the autoguided 1cT mount, is more than a match for what most rigs can put out today.
