best way to collimate dobsonian
Hi all,
I have just collimated my 114 newtonian using a home made colimating cap. It was hard at first but once I figured out what screw did what it got a little easier but was still reasonably frustrating.
I have a 8" dob that is still perfectly colimated according to my colimating cap but I was just wandering if anybody had some helpful hints and tips for colimating, any tools that would make it easier than just a cap? I have heard alot of bad things about lasers so I will avoid them, whats your thought on using a collimation cap?
The only thing that I find with the cap is it is very hard to see the 3mm eyehole reflection in the centre of the primary donut.
Thanks all
Dan
