Losmandy OTA counter weight rail w/2.5lb weight for C11 or M10
After receiving a few messages about the Losmandy OTA counter weight, I thought I’d explain what this does…
This component will work with both fork or GEM mounted OTA’s. For fork mounted OTAs, it sits on the bottom of the OTA. For GEMs it sits on the top. The weight is slid and fastened along the rail to obtain optimal balance.
Why is this important? Inherently SCT OTA’s are back heavy as this is where the primary mirror resides. Usually the combined weight of the corrector plate and secondary mirror balance the weight of the primary mirror, however when you begin to add accessories on the back of the OTA such as 2” eyepieces, Crawford focusers or cameras, the weight is no longer balanced. This is where the Losmandy OTA counter weight assists. Those serious about astrophotography will realise the criticality of good balance. Good balance can also reduce the wear on your equipment motors and gear.
Thanks.
