"Just got in from a three and half hour session outside. Went
wonderfully!
This new mirror
cell collimates much, much easier than the stock cell. I had no difficulty
getting the scope well collimated. And I either had a night of great seeing,
or these modifications have significantly improved the image quality that
I'm getting from the scope." - Mike J.
Reposition the primary mirror with this tube extender cell.
Custom designed to your preferred distance back, attaches to OTA using
your tube's existing bolt holes. Reduces torque on the focuser. Open back
design facilitates quick mirror cooling. Collimation bolts allow fine
tuning. Cells are flat black.
Integrated mirror retaining ring eliminates star flaring (compare
before/after).
Mirror support point positions calculated to provide optimal support/performance.
For up to 10" imaging Newtonian telescopes. After receiving your
order we will e-mail dimensional questions for designing the cell. After
designing we provide a PDF with dimensions for your review and approval
or revision.
