Apertura 50mm Extension Tube
for 10" & 12" Apertura RC Astrographs

This Apertura 50 mm Extension Tube is designed for the Apertura 10" and 12" Ritchey-Chretien Astrographs and is machined of aluminum and then black-anodized. The RC1050 comes with female M117 threads on one end and male M117 threads on the other. It is meant to be placed between the telescope and the focuser to extend back focus by 50mm.

You can stack different lengths of extension rings to achieve the back focus you require for your imaging set-up. With an extension added at this location, you won't have to extend the draw tube as far, which will minimize downward tilt with heavy loads.
