![]() The corrector provides illumination and correction up to 60mm image circle diameter. – TSFLAT3 – 1.0x corrector: The corrector is screwed directly onto the M92 thread of the focuser. The TS-Optics Photoline Apo can be combined with all suitable correctors. This even allows the use of binoviewers without glass path compensation. There is a generous working distance of 140 mm from the 2″ receptacle, which can be further extended by a removable segment between the tube and focuser. The drawtube is ball bearing mounted for precise adjustment even under extreme loads such heavy cameras. The telescope comes with a high end 3.7″ focuser with rack and pinion drive.
