Celestron piggyback mount
Sunday, 2 February 2014 | Mark
Bracket seems to be well made but you need to tighten the mounting screws down really tight or the bracket will slip.
You will also have to re-align the star pointer with the telescope.
The design of the bracket could be better, it only rests at 2 points along the rim of the telescope which is not really good enough, also it is now possible to move the finderscope out of alignment by touching it slightly where as before adding the mount it was not easy to do so.
