Hi Everybody,

I have an apq 100/1000 with m68 focuser and have for the moment a lot of problems to make fine focusing (double stars) because the focuser is very hard to rotate and the picture is shakking a lot (at high powers +200 X).

Has ever one of you seen the problem do I have to put more lubricant on the focuser. It looks easy to unscrew. If yes what type of lub must I use.

I have tested an friend's APQ 100/640 with the same focuser and this unit have a smooth and soft movement.

Any information or experiance will be apreciate
Thanks forward

Hi everybody,

I have posted a thread last month about the focuser of my APQ100/1000. The focus was very hard to make. First I tought that was a lubricant problem...but the only help I get from the Amart's Zeiss community was just the right answer. It's just one of three screws that are using to center the moving part of the focuser inside the optical tube (see pictures attached) that was not fermly screwed. Now it's a real joy to use this focuser and I must say that I find it a lot more better than the TMB focuser used in the CNC version of my 152/1200 APO even at very high powers. Just a simple allen screws gives me so many unconfortable nights of observations. Somethimes I just leave the APQ at home in his box while making a trip to a dark site just because of this focuser.

PS : Special thanks to KIM COLTER for his big help AND of course thanks to ZEISS forum...We have to keep it ALIVE it's a big source of informations for all of us.

Hi Zeiss Fans,

Here is just a picture of my APQ100 on the Ib mount used outside with a power inverter 12v- 220 v.

It's a great apo
I already own a Vixen 102 fluorite, a Pentax APO 75 mm and a TMB152 apo.
THE zeiss is a better performer than the Vixen no doubt about it (sharpness and color correction). But the real question is : does it worth the extra money it's only a 4 inch after all...
