Yes Ive seen most of Astronomy Sheds videos, saw this video a number of years ago and it seemed way to extreme in regards to Collimation of a basic newtonian reflector. A 20min to 30 min exercise
I use 6” and 8” newts for imaging and a 12” newt for visual and have used a Cheshire and laser collimator with good results for years , takes me 5 mins or so
I reckon as soon as you use this method to get your Collimation 1000% perfect , when you fit or change your various eye pieces or imaging gear , temperature drops through the evening , slewing around etc.. maybe a slight bump here and there , your Collimation will change slightly from being 1000% perfect to something less and won’t really be noticeable in your field of view or your images , so what’s the point of such a meticulously long winded detailed Collimation process , I doubt whether it’s going to make your stars look tighter or sharper etc... It won’t fix coma , pinched mirror , tracking error , poor guiding , poor PA and so on .....
I stuck with the good old fashion simple,reliable, quick method that works fine for my basic newts
After collimating at the start of an imaging session, I just perform a Star focus test during focusing using my Capture software APT ( usually a mag 2.0 to 2.5 Star )diffraction spikes are always like super sharp swords , all even , no double swords or spikes and Star centroid spot on
For visual I just focus on a bright star at 150 x mag and same deal, nice even diffraction spikes and centre of Star pin point
Each to there own
Good luck with it, I hope someone who uses this method can advise so it eventually works out for you in the end
Cheers
