Close but I think you're a decade off. The proof is at 5:24. In 1977 if you bought a TV it didn't have a square screen like a monitor. That's 1980s I think. Just an opinion. Could be wrong.
What he failed to mention or make very clear after dropping the secondary mirror assembly down the 'OTA' or 'Optical Tube Assembly', was; "This will likely lead to primary mirror damage!", "Do not let this happen.", "Do this step in a horizontal or front/downward angle." Yes he does mention a caution warning.
Well technically that area is not going to be used. But yeah, razor blade and telescope mirror are two words that should never be in the same sentence 😂
Thanks for the upload... I don't have a laser collimator yet so this was very useful. Also well explained and when you understand the concept you can collimator better.
Great video. I especially liked the tip about using a couple of extra washers to center the spider. My telescope is sporting two extra washers. Great tip. Thank you!
I think those crosshairs are from the spider. That cross section at the top of the optical tube. This is normal for Newtonian telescopes. You'll see them if the image is out of focus, but they will go away once you focus the image.
In 1977 a digital lcd watch cost around $2k. Now they're a buck or two. That was when a dollar actually had some value still too. Crazy expensive technology. Laser collimator...oh God. Just yesterday I called a guy about a used orion 6 inch reflector telescope that's around 20 yrs old. Asked about a collimator and he said, "you do it manually there's a procedure in the instructions". That was all I had to hear...click.
"This video will not collimate your telescope for you"
Damn I thought it would 😑
That decor...and that stache. This has 1977 written all over it. Well done vid though...hehehe

@@mikeries8549 The hifi equipment + chunky watch makes me think maybe 1990s.
No fuss just good sound advice and instruction......Well Done.

The best video on Newtonian telescope mirror alignment.
I stopped watching after the razor blade part......

Excellent explanation! Thanks for sharing.

Great information... thanks.
Burst into laughter at the 0:19 mark 😂😂😂😂😂😂😂
Over complicated
This must be from the late 1980's, early -90's. The (lack of) video quality was the hint, but the moustache really gave it away ;-) Great vid, thanks.
Can this man please be memed
Great video. I especially liked the tip about using a couple of extra washers to center the spider. My telescope is sporting two extra washers. Great tip. Thank you!
Love the music
AWESOME.
yeas ? 1901 ?
I have a NEWTONIAN 150/750 and have collimated it to precision with a laser collimator but STILL SEE crosshairs!
Can you help? What am i doing wrong?

i did exactly what was done on 8:59, even without having known about this video.
Did they not have collimators in the 80s? Also I have alignment screws and markings for both mirrors on my newton

Newtonian telescope making in Hindi video video please
Who says you can't bend light?
Me
Great old school vid 👍
only my left ear listen
That stache tho
cool
Excelente video, muy instructivo
Gracias
