Lacerta Off-Axis Polarscope Adjustment Unit for PolarieOAH-1 (Polarie Off Axis Holder) with M28x1 Locking Ring
This unit makes it possible to fix and adjust all polar scopes, which have a tube diameter of less than 26mm, into the Polarie Off Axis Holder.
This unit "PolarieOAH-jus" is already implemented in the package "PolarieOAH-ill".
Although this unit is not necessarily required if your polarscope has already got an adjustable reticle (Skywatcher EQ5, HEQ5, EQ6), however adjusting that reticle with a screwdriver is very time consuming and difficult task.
It is much easier to achieve the same or even better result with this device as you will be using thumbscrews for adjustment...
Length without thread: 33mm
Length with thread: 40mm
Internal diameter: 27mm (where the adjustment screws are)
Internal diameter: 24.6mm (where the large thread is)
Outer diameter: 35mm
Thread: M28x1 (it measures 27.85mm, so it's most likely M28; the pitch is certainly 1mm)
Images are for demonstration only! Some images will show the optional PVixen Polarie and PolarieOAH-1 adapter as well.
