- Hey Astr-folks,
this time we collimate a Newtonian Telescope using #svbony Laser collimator & the Cheshire Collimating Eyepiece.
It is a four step process and very crucial whenever opting for the best results using your beloved telescope. BUT: The steps are very easy and we will go through all of them in this video. So "no worries" and let's go!
Clear skies! -Chris

Thanks for a great video. You have a very soothing voice 😃
Haha thanks! Cheers!
FYI, I wrapped the tip of the collimator with blue painter’s tape going all around by not overlapping, this will make the collimator straight and there is no need to use the thumbscrew so no misalignment.
Good trick, thanks a lot!!
Great video! Thank you!
Good tutorial. I would add one thing that is inevitable - equipment screwed on the focuser will cause sagging and loss of collimation. Therefore it is a good thing to gently sag the focuser with a similar amount of force while collimating the secondary to primary and primary to focuser. It will never be perfect, but additional level of precision can be reached that way.
I'm really curious if your SVBony Laser Collimator came collimated? I just got the exact one you show in your tutorial and it was way off. Laser beam drew 1/2" circles on the floor. And yet they plug up the holes that allow you to adjust the laser to bring it into collimation. It wasn't all that difficult to do. I'm sure I voided my warranty by removing the rubber glue they use to plug the holes. But it was worthless to me as it was out of the box. Luckily, I watched enough UA-cam videos to understand how you collimate a laser collimator. And once I had the collimator collimated, everything worked like it should. And when you rotate the collimator, the red laser dot stays put. And the Star Test was amazingly good. So I'm happy with my purchase. Just disappointed that SVBony plugs up the holes.
Oh no! That's annoying! 😐 Glad you could solve the problem. My laser was A-OK when taken out of the box.
Can you provide us with a link for a good tutorial?
Cheers!
Chris. I have learned so much from you video series. Kindly keep doing more when you have time. Thank you very much.
Thanks for your encouraging comment! Very much appreciated!
True after Im using laser collimator, my calibration to my newton is much faster and no hassle much anyways the SECOND version of SVONY laser collimator has a DOT laser beam compared to their first one which is kinda OVAL in shape. . no too friendly hehe
Thanks for your input! Cheers!
You can also use paper to determine where the laser is reflected from the primary mirror or just the palm of your hand, then you can look at it with your eyes from the safe side.when the secondary mirror is adjusting ~
Nice work Chris 👏
Thanks a lot! Cheers =)
You don't point to the adjustment Laser screws, only talk about it. Also this Svbony is pre adjusted and it double glued so adjusting will be hard. FIRST check to see if when you rotate it if the laser does not stay in the center FIRST before using or adjusting the laser screws! To confirm if the Svbony or any laser, take a 2"x4" x 6" piece of wood and used 4 round head screws 2 for the front and 2 for the back of the laser laser and place the screws so they are placing the Svbony laser in the center if the laser and then when turned on point to a wall 25 feet away and see while rotating the laser that it stays in the center, maybe be take a white sheet of paper and put a circle about 1/4" and place laser wood towards the wall and turn on and tape the sheet of paper putting it in the center of the laser and then go and rotate the Svbony laser and see if the laser stays in the center. If not adjust or if you just got from Amazon return it and get another as newer generation lasers are pre adjusted? P.S I don't like how large that center hole on the laser angled scale is.
Also if you find the 2" Svbony adapter or the 1.25" is a bit loose just take that scotch tape and wrap a bit fully around the metal part that goes into the EP holder and if 1 layer of tape makes it snug your done, if it's still wobbly then 1 or 2 more wrappings of tape should make it snug.
We decided to look down tge barrel of ours from a few meters away and have someone look down the eyepiece with enough distance for the light to get through. When you could look through and see the eye clearly and centered, it gave us a fairly good ballpark to start from.
I got the Svbony laser collimator. It has two problems. First, the movement of the screws is not enough to collimate the collimator itself. Thus the laser is always pointing at an angle no matter what I do. Second, the electrical switch is defective: I turn it into position, knock on it, and sometimes it turns on.
Thank you 😊
❤you said this video would be about using a laser collimator but instead you instructed how to use a collimation cap which is DON’T have!!!!!!! How frustrating!!!!!!!!!
Oh boy! 😯 Please note that you can buy a film roll for
no more videos? :(
I'm working on it. I moved and this took sadly all the time there was. Now I'm getting ready for the next round 😀
What the hell is a "Newton" telescope?
Purhaps, "Newtonian" was meant?
It's a Newtonic telescope, bruh
Probably....
15 min of talking when 5 would do. 8 would be ok.
How much talking vs showing how it worked?
:-) sry. Talking is my business. Hope you could take something away anyway. Cheers!
