The mounting clips are not the only advantage in a conical.
You have the quicker cool down time and the lighter weight of the mirror.
The weight can be an advantage or a slight disadvantage when it comes to balancing.
The simplicity of not having to make a normal mirror cell with the plop mirror mounting points.
I can remove the mirror from the stud for cleaning with the removal of only one bolt and replace it and the collimation will not have changed.
As long as the mirror is placed in the same orientation with the aid of a couple of dots on the cell and mirror sides.
The only disadvantage i can think of is the slightly higher price of a conical and the lack of a reflective centre spot for collimating.
As far a laser collimator i only use it as an aid as it can't be used to it's fullest for the reason above.
They also need to be checked for alignment them selves as mine cam out of alignment.
I used my eye , a Cheshire and the laser and don't rely on one method alone.
It will get easier as experience grows.
Yes it can be a nightmare trying to do it on an f5 or less as my friend found out and required my help.
It took me a while not having had to do it for so long.
Keep an eye out for my OTA on the forums in 12-18 months or so as I have made my mount to suit a larger aperature and will be looking at upgrading to a 16" Royce Conical or larger if I he will do it.
