Using the telescope for prime focus imaging
Before installing the field flattener onto the drawtube of the
focuser, the 2" ring adaptor

needs to be unscrewed and
removed.
In order to easily unscrew the ring, hold with one hand the ring
(1)
at the end of the drawtube and then unscrew the 2" ring adaptor

with the other hand.
The Sky-Watcher ESPRIT 80 Field flattener has been specifically designed for your
telescope. It guarantees excellent field flatness across the entire 33 mm imaging plane
and ensures full illumination with extremely minimized halation and zero color fringing
even on bright objects.
No "universal" field flattener available on the market will deliver the premium results
achieved with the Sky-Watcher ESPRIT 80 Field flattener which is designed
exclusively for this telescope.
