About this image

I have always had problems in achieving perfect collimation with a GSO RC10. I always end up with triangular stars no matter what I did. I took the bull by the horns and follwed the advice here:

I had to butcher the plastic goo holding the mirror in place and replace it with velcro pads.

It worked a treat and can vouch for the validity of this advice!
