Gday Mate
On the reccommendation of a mate I got an Optec NextGen Ultra Widefield 0.7XL for use on my Black Diamond 120.
I didnt have the correct hardware for the marriage of the reducer to my CCD (the correct h/ware has arrived this week) so I bodgied somethiing up on the lathe and tried it and it performed fantastically in test shots. I didnt have the correct spacing to achieve the optimum 0.7 reduction but it was fine from corner to corner of the large CCD chip.
I will give the correct set up a full test run this weekend out at the observatory and let you know how it went.
