Sky Watcher Primary screws
I am just wondering what other people do regarding the Sky Watcher 8'' Dob Primary Grub and Phillip screws.
To make it easier to adjust for collimation apart from bobs knobs, what do other people use instead?
Not sure if it is worth putting in springs and removing the grommets that are there for the adjustment ones.
If you do, I would like to know your opinion.
Regards
Michael
