Collimating a Newtonian Telescope

1. Хорошее объяснение. Все понятно для начинающих любителей астрономии! Спасибо! Но чеширским окуляром юстировка точнее!
2. Really good video but it could have been improved by mentioning that pretty much any laser collimator you purchase will need collimating before the process of inserting in in the focuser. If the laser was out of collimation, could I still insert it  into the focuser and then alter the secondary mirror as shown in your vid ? also when i adjust my primary mirror to get the red dot in the target, it produces red lines even if I turn the brightness down, this makes centring the beam in the target tricky but possible. In the vid it does not show this and clearly just shows a red dot only. It is almost like there is to much light around the target area and not just a small red beam, looks a bit like reflections from the laser beam just illuminating above and below where the centre of the beam is pointing.

4. You guys are awesome, subbed
5. excellent tutorial you have explained the collimating process to me very easily and I am a newbie who has not even looked through my telescope yet.
6. I could listen to this dude talk for hours.
