I was intrigued when the  original thread discussing the Breser AR102 F4.5 started way back in April of 2017. When a lens appeared on 'Surplus Shed's site for a 100mm F4.5 lens I ordered one. Within a week of its arrival I had constructed an OTA. I used a GSO 10 to one 2" focuser with one inch cutoff the drawtube (to aviod vignetting).  This scope has become my favorite RFT combined with a 2" 22mm 8 element eyepiece it offers excellent views with edge t edge correction. Surplus Shed no longer offers this lens but there is one for sale on the classifieds today..

Hope everything is okay now!

 

As seen in my signature, I went for the eyepiece (the ES68) and it was a huge lift! Then the plan is to save for something better, right now leaning towards the TS102ED f/7 doublet (the cheaper with FPL-51 glass).

 

Regarding the other subject I have kind of reached a conclusion to get an AZ-EQ5, which would hopefully resolve the questions I had. However, I see that you actually have that mount! So your input in that subject (or the other subject I created about AZ-EQ5 vs CEM40) would be very interesting! 

 

Hopefully this didn't stray too far off topic, still touched on the fact that I will save for a better refractor than the Bresser. 

IMO, that is a wise decision.

 

Indeed -- money best saved towards something better.

 

The Bresser can be fun to play with, but is a fairly compromised scope in most parameters of optical performance.
