I have a Starizona hyperstar for sale which fits a C6.
This one comes with two adapters to fit either a non cooled ZWO camera or a cooled ZWO camera, so it is a very versitile arrangement. It brings the focal ratio for the C6 down to around f2 and the focal length down to 300mm. An image taken with my C6 and the Hyperstar of the Horsehead nebula is attached.
The hyperstar comes in a hard plastic, form fitted cast so will travel without any problems. The hyperstar itself has an easy to use set of push / pull srews at the base which are easily accessible and make collimation a breeze. It takes just seconds to convert the scope to hyperstar or from hyperstar back to a standard C6.
To buy this system from Starizona will cost
Hyperstar: $499.00
adapter $ 89.95
freight approx $100.
TOTAL $688.95
convert to AU$887.25
add GST = $975.98
I am asking just AU$600 and I will cover the freight.
