I own an original Japanese Vixen Super Polaris telescope. I bought it second hand about 25 years ago and I believe it was about 5 years old then.
It has a fully motorized EQ5 mount which is driven by a very primitive Vixen 'GOTO' controller. I feel this scope is fairly rare, especially due to it's white Vixen 60 x 700mm guide scope which sits on top of the white 102 x 1000mm main tube.
There is very little information on the Web about this scope, most are black and are marked with the Celestron brand.
I no longer use this scope and have no idea what its value would be or even if these older scopes can match the performance of a modern day equivalent. How good are they?
Perhaps it might become a collectors item one day, although it is completely functional now.
It gives great sharp views but I have noticed a purple coloured fringe around bright objects such as the moon, I have read this is quite common with some achromatic refractors.
This would have been a very sophisticated instrument 30 years ago! Any feedback on the history or rarity of this scope would be greatly appreciated.
Cheers,
Mike.
