Hi All
What do people here think about the Astro-Tech refractors. I'm not talkin about the Italian AM ones. These are the taiwanese ones. They used to have 66 dia before but now bringing out the 90 and the 102 in trip apo with 53 glass. They use a rack and pinion 2 speed focuser (anyone can explain the diff between this and the crayford?).
This is the one im looking at
