This isn’t very helpful for the amateur. A,how do I attach a camera and B, where do I get an artificial star and C, how do I get the cap off to see the screws.
Fantastico! Muito obrigado pelo video! Greetings from Brazil
Excellent video, thanks a lot!
Is there anyway to collimate a Schmidt-Cassegrain telescope without going through all of the things that you do? What happens if nothing gets in focus when pointed at a star regardless of what is done? Mine is a nightmare , and the only thing that I see is a out of focus light. And where is the star or light at in relationship to the secondary mirror when looking through the eyepiece? Is it behind the secondary mirror or along side of it?
just the video iv been looking for…good work
Great video, but please keep that screwdriver away from the optics! Replace the collimation screws with knobs that can be turned using clean hands. Fingerprints are far more forgiving than a fumbled metal tool. I couldn’t stop from cringing every time the screwdriver passed in front of the telescope.
unless you are throwing your scope down the stairs…
Bravo.
Love this video thanks for posting.
Excellent advice, thank you.
Awesome video! Thank you for taking the time and effort to make this.
What about the corrector plate, isn’t that a step before collimating the secondary?
I accidentally removed the secondary mirror of my cpc 1100 , i put it back but the images appear like a streak. I disturbed the collimation severely, Should i try the method you mentioned above (its going to take a long time) or is there any other way to collimate it?
I do that in reverse, first move the scope so that the ring looks the best (doesn’t need to be in center), then adjust screws to move the ring to the center of eyepiece….. repeat until the ring is round and center in eyepiece
also only loosen the screws one a time… that means if you loosen one, you tighten the two others
Thanks for making video. The instructions that came with mine said to “move” the rings to the edge of the field of view and then adjust screw to make rings symmetric. Does it matter whether it’s centered in the middle of the field of view?
nice!
Thank you sir. very helpful.
Very helpful especially the trick of placing the screwdriver out in front of the telescope to work out which of the 3 adjusting screws is closest to the small side of the image
amazing video,,, to be honest, after reading the telescope manual regarding the collimation I found it hard and complicated. But after watching this video….. is it that much easy !!. thank you sir
can you use a normal star
Thank you
Thank You 🙂
Thanks it gives the basic of what you need to do especially good for those that Macgivyr their needs as most amateurs do.
Wow, is it really that easy? That seems amazingly easy!
Question: What is the best magnification (eyepiece) to use to get the diffraction rings? How far out of focus should we have to go to get them? Thanks.
Well, done. Very helpful.
I own a celestron 4SE this is one chore I hope I never have to perform.
A million thanks!!! Very helpful to me indeed as I’ve the same telescope with me and collimation has been a nighmare for me… 🙂 🙂 🙂
