Review on Alstar Superior Multiple 5 Position Telescope by Louis Alford
Ideal for 1x NV and with 67PP
Ready for Televue/TNVC system with M48 connector. 1x is easy. 55 Plössl with its 67 mm focuser works with all my scopes due to its extreme blur position. Back focus was never an issue as it has a Paracorr Type 2 position around B. Other more conventional eyepieces like the 41 Pan require the wheel to be screwed directly onto the refractor star diagonal. 31 Nailers can have problems because they need back focus in combination with your star diagonal. The specified optical path length is accurate to the body. The M48 connector only adds a few mm, but not much.
