Pegasus Astro
Pegasus Astro Orbit Rotating Diagonal
$310.49
What the numbers mean
The optical path, translated.
3editions
One rotating diagonal, three telescope connections.
Basic, SCT 2-inch and SCT Edge editions share the Orbit body. The difference is the telescope-side hardware and the backfocus path it creates.
2rotation points
Set each side independently.
Separate thumb screws control rotation at the telescope side and the SmartEye side, so the connected equipment can be oriented without turning the whole optical train.
λ/10at 633 nm
A specified first-surface mirror.
Pegasus specifies BK7 glass, an enhanced aluminium protective coating and average reflectivity of at least 92% from 450 to 650 nm at 45° angle of incidence.
1.25 infilter thread
Use a standard 1.25-inch filter.
The integrated filter thread keeps a standard 1.25-inch filter within the Orbit assembly.
Choose an edition
Match the telescope side. The Orbit body stays the same.
