Collimating a Ritchey Chretien telescope with the TSRCKOLLI tool

[@HerbsGarage]

Very nice ... finally great to see somebody that actually knows what he's talking about ! Vielen Dank.

[@ssadams]

I am looking to purchase one of these scopes and your video help put the fear of collimating to rest. 👍😀

[@orionnebula3487]

I don't see the outer ring to collimate the primary mirror. Only when I close the telescope lid. Can that be right? I have the TS Optics RC 8".

[@starpartyguy5605]

I have the tskolli tool and used it today. I think I have everything aligned and ready to go. And that’s when the clouds rolled in.

[@asmxh]

Just received my TSRCKOLLI. Worth every penny. So simple to use. Everything on the video was spot on on how to use the tool. If you own a RC scope you would be a fool not to have one of these collimators in your possession.

[@Bakrybaso94]

Were you able to see the outer ring? I can't see it in mine

[@paskoh]

Hi there. I would love to see how you would collimate a refractor with this. Thank you.

[@SuSebaSu]

How critical is a secondary to primary mirror distance? You mentioned that the screw should be loosened a bit, but many sources mention that this one shouldn't be adjusted at all.

[@teleskopservice]

Hi Sebastian, the distance is indeed important for RCs! It should be in the range of +-1mm from the distance given by the mirror specifications. but here for the collimation, i opened the screw just a fraction of a turn to give the outer collimation screws a bit of "room" to operate.

[@christinelaulhere4103]

Merci beaucoup pour cette bonne video!

[@ioan_astro]

nice tutorial, I use this tool to double check my collimation on a 12 TsOptiocs Truss tube and it's actually pretty easy to use, amazing little product for this price!!!

[@asmxh]

Nice piece of equipment. I just ordered one. Looks pretty simple to use.

[@alfredobeltran611]

Very clever device which makes collimation simple. I wonder if you could you make a video on collimating a SCT such as the Celesteon EdgeHD

[@ahmedrizwankhan]

Would love to see that too

[@MrGeeFoto]

It was basically a good video ;) Thank you!

[@ahmedrizwankhan]

Would love to see how you would collimate an EdgeHD scope with this.

[@kuendla2453]

Please make a video collimating refractors as well. I have bunch of refractors and Edge 8 HD. I'd like to see how it works on those

[@jensploner2877]

If you say the W is set for collimating refractor telescopes, I'm wondering how this is gonna work?

[@daltonortega]

Hello, I have a few questions. Is your view of the collimator when illuminated red actually that big? Or is that an effect of your camera lens? I am viewing with my naked eye and the collimator is quite small, with the circle and dot being even smaller. I am guessing I'm pretty much aligned with the secondary. Next question, regarding the primary collimation, I can't see the white ring on the outside at all, so there is no way to balance it. I have no extenders and the focuser is completely racked in. Any thoughts?

[@teleskopservice]

Hi, the view is indeed quite small. In the video it is magnified. Yes, i heard about this issue with some RCs. In newer designs, the baffles are extended a small amount wich blocks the light. This is a good approach to block the stray light but unfortunatly then you cant use this "light ring" for adjustment anymore :(

[@daltonortega]

@@teleskopservice Thanks so much for the quick reply. Sad to hear that it wont work for this RC. I guess my other option is a different collimation tool. I've got an artificial star, but I do back yard astro and can't get enough distance in order to get the scope in focus.

[@indysbike3014]

​@@teleskopservice So which collimator do you recommend in that case you don't see the outer ring?

[@teleskopservice]

@@indysbike3014 www.teleskop-express.de/media/pdf/TSRCKOLLI-G2_de.pdf Page 7. The light ring is either visible or not; this has nothing to do with the adjustment device. You can remove the aperture tube and use the secondary mirror spider for orientation, but it also works as described in the instructions.

[@dummag4126]

and the green leds? are they for what?

[@mtnphot]

Thanks, this is a useful video, however I am a bit confused about loosening the centre screw on the secondary. While it eliminates having to adjust the other screws, can't that affect the secondary to primary mirror distance?

[@bogdanvuk3422]

With the TS-Optics 8" Ritchey-Chretien Pro RC Telescope 203/1624mm the outer ring is not visible. How can I collimate the primary mirror ?

[@marcoscancino4876]

Same here !, i dont see at all the outer ring on my RC8. Is that normal ??.

[@pedersonploeren]

Same for me with RC6. When I switch on the white LED , i can see outer light ring but in your video, you have the outer ring without white led ..

[@J.DiPietro]

Same here. Have never been able to see that outer ring.

[@BillCCD]

Reduce the distance of the collimator to the back of the scope. This may entail removing extension rings if installed.

[@bogdanvuk3422]

@@BillCCD I have removed everything. Even if I remove the focuser I can't see the outer ring, but I can see it, if I look at an angle (10-20 deg) from optical axis, but this is not the position for collimating primary mirror.

[@melodasi]

Very good video, I struggled with my RC6 for quite some time until I got the Takahashi colimating scope.

[@christopheguigot841]

Bonjour pour un c8,c11 xlt ou en hyperstar ça fonctionne…? Merci beaucoup.

[@markbergendahl2651]

Very good tutorial !

[@GrahamD991]

Could you also show how to use the tilt plate and collimate with that in place at some point ? Thank you !

[@teleskopservice]

Hi Graham, sure, i'll put a video together with two options how to adjust the tilting properly. Stay tuned, i'll keep you updated when its available! Cheers

[@Bakrybaso94]

@@teleskopservice Any update on this? I bought the TSRCKOLLI and GSO Focuser Collimation Ring / Tilt Adapter and not sure how to use them together :/

[@stilianoskalatzis7491]

Wonderful video and helped me a lot with my RC6, that being said can you make a video using this collimator on a refractor scope please.

[@One1Raptor]

I dont see any light at the outer ring, when collimating the primary mirror?

[@GrahamD991]

Thanks for a good video - I have struggled with Collimation with my TS RC6, I may get this Collimator ! (I've already made my own artificial Star with a LED and a Optical Fibre TV Cable !

[@SpaceFactsWax]

Thanks for uploading. I got the chance to see a rocket launch in 2018. Memorable experience. I shared a pretty fun montage of the journey to my page.

[@GillAstro]

Hi, like @orionnebula3487, I don't see the outer ring to collimate the primary mirror with my TS Optics RC 8".

[@teleskopservice]

Hi there, can you contact us via insta or facebook or by e-mail ? [e-mail] we will be glad to help you ! Best

[@alexm7056]

But what if the top edge primary baffle is not optically aligned with primary mirror? Instructions for secondary collimation are alright though! Will try to 3D print the device to save some buck

[@NielssBohr]

I would like to get a video on how to use the artificial star to achieve PERFECT collimation. Also with a tilt plate it would be best to make this sort of video.

[@teleskopservice]

Good Idea ! thansk for the Input ! we will notice all and consider it for future videos ! Teleskop-Service

[@jaymsohn]

When I want to add the focuser collimation with a collimation ring to eliminate possible tilting, can I do it with this TSRCKOLLI? or Need another one like a cheshire eyepiece?

[@ss1204]

question: the central screw regulates the distance of the secondary, if you unscrew that you are basically changing the distance of the secondary right? or i am wrong?

[@CarloFanuli]

So, this collimator is good also for Newton 10" F4? The procedure is the same? Thanks a lot

[@hael8680]

Do you need to adjust the tilt of the focuser? Why is a tilt plate available for those telescopes?

[@teleskopservice]

Because the focuser is "connected" to the primary mirror, you will always change the tilting of the focuser when adjusting the primary. With the small 6" this was not a problem, but it can be. Then you have to iterate multiple times through the process until you get a good result. That can be annoying and the tilt plate can help (because it decouples the two elemets)

[@hael8680]

@@teleskopservice thank you for the reply. If you install a tilt plate, how do you align the focuser?

[@throughtanlens]

@@teleskopservice yes... i would like to know too how to collimate the focusser with tilting plate with this tools

[@jimmcallister3795]

Are these available for purchase, they appear to be out of stock?

[@miketronix]

Nice video. Out of curiosity this does or doesn't work on edgehd telescopes? Looking at the website it says as long as they have a center dot on the secondary mirror

[@I_Spaced_Out]

It won't. But Edge HD telescopes are much easier to collimate anyway. Just point at a bright star in the sky, defocus the star so it looks like a donut. Adjust any of the 3 screws for the secondary mirror that corresponds with the offset shadow in the middle to push it or pull it back to the center. And that's all there is to it.

Hi, das Video hat mir beim meinem baugleichen Omegon 154 in sofern geholfen das ich erkannte auf dem Falschen Film zu sein, ich hatte zuvor mit Laser versucht zu Collimieren was aber ohne den zusätzlichen verstell Flansch am OAZ welcher den Laser führt überhaupt nicht mach bar ist und außerdem Sinnfrei wäre weil es einen Rattenschwanz nach sich zieht. Ich dachte mir da kann was nicht passen den egal wie ich das einstelle mein Laser wird vom sek. Spiegel zurückgeworfen und trifft auf die Verspiegelten Laser Optik der den Strahl solange hin und her schmeißt bis es dann nicht mehr den Spiegel trifft.. ich wusste schon gar nicht mehr nach welchen Punkt ich überhaupt gehen soll, und nach Anbau der Cam war überhaupt nichts konzentrisch eingestellt. Ich hab das jetzt so gemacht wie du mit einem selbstgemachten Pinhole Einschub.. Oldschool like.. Die ganzen anderen Videos mit Laser bringen überhaupt nichts wenn man nicht auch den OAZ im Winkel verstellen kann. Ich hab aber ne ganze weile gebraucht bis ich das geschnallt hatte denn ich war mir bei dem innen Aufbau des RC nicht im klaren und es ist dann schon ein wenig anders als ein reiner Newton. Anfänglich ging ich davon aus dass das die Verstellung rund um den OAZ nur zum einstellen des OZA ist, das Omegon hatte ich noch nie ganz zerlegt sondern nur mal den Spiegel ausgebaut und gewaschen. CS & Thx

No a good idea to loose the central screw on the secondary mirror.

[@Bobby-fj8mk]

It would have been better to start with the telescope way out of collimation and adjust it till it was perfect.
