When the imaging train is this
position you need to adjust the
focuser’s tension by using the
large thumbscrew below the
focuser, as shown in
[
Fig. 8
]
. A
correct
tension
allows
to
smoothly focusing
but doesn’t
let the imaging train move due
to gravity.
When in focus and centered
don’t forget to block the
focuser drawtube with the
thumbscrew placed on top, as
shown in
[
Fig. 9
]
