♦ Connection at telescope side: T2 thread (male)
♦ Connection at eyepiece side: 1.25" receptacle (female) and T2-thread (male)
♦ Adjustment range: 10 mm with a setting accuracy of 0.05 mm
♦ Minimum height: 47-5 mm
♦ Non-rotating helical: the accessories do not rotate when the focuser is rotated
Telescopes with primary mirror focusing often show "mirror shift". The image shifts or springs whenever one tries to focus with the primary mirror. Additionally, focusing is quite coarse, testing the photographers patience especially in planetary imaging.
The TSHeli1 also solves this problem through a very precise focusing without shift. For adapting the TSHeli1 to the 2" Schmidt-Cassegrain thread, you only need:
♦ T2i-T2i ... T2 reversion adapter - turn a male T2-thread into a female T2-thread
♦ TSSC-T2s ... adapter from T2 to the SC thread.
You can find both items in the "recommended accessories" section.
