Salvatore G. Verified Buyer –
As soon as my order arrived, I carefully followed the online instruction video on “How to install Apertura Collimation Knobs” which made the replacement process less intimidating, and the installation very straightforward. These secondary mirror adjustment knobs have made collimating my telescope so much easier than fiddling with the 2mm Allen wre
nch hex key.
My mirror alignment viewing attention is no longer distracted away from my Chesire eyepiece while trying to insert the cumbersome wrench and grab the secondary’s adjustment screws. This upgrade solution is a must have for stress free collimation.
