Near perfect collimation

After a couple of interations between main mirror adjustments
while viewing through the TELECAT and secondary adjustments while
viewing through the INFINITY, perfect collimation is seen
here in the INFINITY with the multiple triangles now merged into one.

NB. The faint double image bright triangle visible in this photo is a
result of the camera being hand-held against the INFINITY for 15sec to
get the picture, the naked eye view revealed just one sharp triangle.
The very faint skewed overlaping triangle wasn't visible to the eye
but has shown up in this 15sec exposure.

I think this should be about as close to perfect collimation as is practical?

The INFINITY autocollimator is a highly sesitive tool and more than enough for
most applications.
