If you want to visually magnify higher or need a longer focal length for smaller celestial objects, you should take a look at the 130mm f / 9.2 triplet SuperED Apo from us.

2015年12月20日 · It also holds true that the TMB/APM 130 f/9.25 is simply the heart cut out of the TMB/APM 152 f/7.89. Same focal length of 1200mm with a reduction in aperture. The TMB/APM 152 f/7.89 is a fantastic instrument, as are most of the TMB designed LZOS optics. As most people understand, the color correction is in large part due to the mating glasses ...
