OPTEC f3.3 REDUCER
This is a rare as hens teeth OPTEC 3.3 reducer, works well with a ZWO 183 MC or MM Pro or similar small chip cameras. Works better with older Meade's or current non HD Celestron SCT's. You can get acceptable images with ACF SCT'sI no longer need it as I use Hyperstar now.
Manufacturers Description:
Designed especially for the classic Meade and Celestron SCT's, the NGM yields an incredible f/3.3 effective focal ratio (EFL) on native f/10 systems. When used with an f/11 classic C-14, the NGM will yield an EFL of f/3.7. Results may vary slightly depending upon the imaging train configuration.
