Also, consider this. Look closely at the cell design in the bigger brother 16" RC (
attached). That is a proper 18pt mirror cell.
Looking at my cell,
attached, we only get a 3pt cork support system on the the 12".
It seems that GSO has modelled their new new and improved 16" RC support system on the stargazerslounge guy's fix (mentioned above) by providing a robust 18pt mirror cell. Pics of his expensive 12" RC after-market mod can be found
here and
attached.
The thing I like about my simple mod is that it's 100% reversable. No damage to components, no cutting of metal or drilling. You can go back to cork pads (Bunnings sells them), silicon in cell and mirror clips if needed. The idea of velcro might be new to some, but the big dob guys - experts in primary mirror cell design and support - use it with great effect I'm told.
