Masterfull presentation - You are an asset to the astronomical community - Many thanks!

Having just bought my first SCT, this has really helped me understand the collimation process. Thank you!

I think the only part that might confuse some is the bisecting lines paragraph. Maybe just suggest cutting the telescope in half down its length from 12 o'clock to 6 o'clock to designate a left and right side.

How far is a wavelength when you are defocusing. ?
I am collimating a Celestron C8 with Bob's knobs.
