I want to use my Skywatcher 80ED PRO for some prime focus terrestrial photography.

I currently don’t have enough ‘out’ focus. The closest I can get is around 50 meters. I’d like to get that down to 5 (if possible)

The 2’’ adaptor that came with the scope is already threaded for my T-ring. I don’t want to have to buy any more adaptors.

Would this do the job? http://www.firstlightoptics.com/proddetail.php?prod=focusextender

Thanks

Short answer is yes. Either length will get you closer, but the longer one will get closest.
