Wonderful thread! Here’s my APQ 130 (in a Markus Ludes custom tube with an FTF351). Not a stock set-up but the photons don’t care. It’s lineage as I understand it is that the APQ lens began life as a reference optic in some sort of industrial application (used in collimation I believe). It eventually ended up in Markus’s capable hands from whom I acquired it. I’ve also acquired a pair of Dennis’s Zeiss binoviewers. Also pictured is an original Baader Herschel wedge which uses a Zeiss prism. Fine optics but beware the exhaust ! Not pictured is a Zeiss M44 diagonal.
I blame the whole mess on Alan Friedman who lured me in for a peak through his 130 at NEAF one year LOL. That was it for me. If you have the opportunity to look through one I urge you to bolt lest you find yourself endlessly scouring the globe like some Zeissian knight in search of the Astro-grail.
So, if you could have just one eyepiece (or pair😂) starting with the letter Z to tuck into that M44 what would it be? Also , I thought that I had read somewhere that there were 140 of these 130mm lenses made. Can anyone comment on the volume “manufactured”?
