Nice review. Can you please also review the TS Optics 152/900 mm F5.9 achromat? I am interested in that telescope but I cannot find any review on it on RUclips. I am specifically interested in its optical performance on DSOs. Thank you :)

Excellent review. This is a very nice beginner telescope. It would be interesting to see more reviews like this with other telescopes sold by TS Optics.

Hello, Thank you for this valuable video. I recently bought a 150mm28f. I use ASI6200MC pro as a camera. I can provide 55mm back focus with M48 adapter + M54 drawer 2" filter (20mm) adapter + 17.5mm camera sensor distance. But there is a lot of vignetting in the corners. For this, will using M54 adapter instead of M48 solve the problem? Or which adapters should I use? In addition, when I use 2" optolog L-exterme filter, is there a possibility that the back focus will be 56mm instead of 55mm?

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

There junk all lazers they need collimating the cheap ones are not collimated use a cheshire

Can I use Amici prism with this product?

Is there a thread available on the focuser to screw corrector ? A screwed connection is more secure than low quality clamping ring.

Thank you! Very informative, especially the camera settings explained, which are indeed some confusing.

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

Excellent information very well presented. Thank you!

Can you please tell me, specifically to better see galaxies (not astrophotography), which refractor would be the best option, the TS Optics 152/900 mm F5.9 mm achromat or the Explore Scientific 127/952 mm ED-APO triplet ? The 152 mm achromat has higher light gathering capacity but the 127 mm ED-APO has higher quality optics. With my curent refractor, TS Optics 102/714 mm ED, I see galaxies the best at 80-120x magnification, so the new one with bigger aperture has to be able to look at galaxies at those parameters - 80-120x magnification. Thank you!

Very cool video! I have two of your Ritchey-Chrétiens (the 8 and the 12 inch) and I’m so happy with them. I use one or the other depending on the target and they are amazing. I came from a cheap Newtonian and suddenly my photos did a quality leap. Pinpoint round stars (APS-C sensor here), easy to collimate using Ocal and gorgeous star spikes with their rainbow phase just like Hubble’s. I mean what else can I ask for? Well yeah, that they’d be cheaper lol 😆 Will check the channel for more interesting stuff. Cheers from Spain

I just wish there were mounts mere mortals can afford.

😅😅😅well information good show you can 😅😅😅

I also have this scope "TSRC10T", bought it under good price i found, but i didn't use it yet and still in shipping box because i am waiting the day to afford a good mount for it, i don't want to risk it with my current mount even if it can carry it but under maximum limitation of it, thank you very much for your nice presentation, please more presentation about this scope so i can learn how to use it perfectly in the future.

That's a beautiful telescope.

Really like your videos. Also like the fact that TS optics sells upgraded telescope packages.

Great Video sir! One other thing I'd like to add. The rack and pinion focuser upgrade with the TS-Red reducer has another very important benefit. Using that system eliminates the need for 3" of additional (included) spacers between the the focuser and the scope. So the scope is very compact. And contrary to popular belief, this scope is easy to collimate and it holds collimation indefinitely. Its a very well made scope. The coolest looking scope there is.

Great video. I hope for more!

Super..

Es war eine tolle Präsentation.

My TS newtonian has the name StellaLyra on the tube.

What automatic focuser can be used with this telescope? Would SestoSenso Primalucelab fit? Thank you.

I absolutely love my ONTC 8, it is a wonderful scope. I highly recommend it and have enjoyed it thoroughly. However, it pains me to admit that the secondary mirror and the spider are not paired well, at least on mine. The adjustment screws don’t line up with the pits on the back of the secondary mirror. Also, the screws on the secondary feel cheap and have had metal scraping off the threads from day one. Perhaps I have an early model, I’m more than happy to change these out if they have been updated. I’d love to hear from others about this

Like! Is it true that triplet refractors lose collimation faster and more easily than doublets and have to be recollimated more often ? Thank you!

Very very help full bro very very very very helpfully 😊

I really liked the look of this scope which would have solved a few of my problems, one being the size and construction of my current scope. (Skywatcher) BUT. I've read some of the comments on the forums and it appears that many of these scopes arrive with bits falling off them! Now I'm sorry, but if I'm paying £2000 for a high-end scope I don't want to be repairing it on arrival. Course I found out where they are made and it turns out that it's made in China (P.R.C.) what a surprise. 👎

Ich hab die Touptek 2600c Einstellung Gain 100 und Offset 150 soll ich auf 120 runter gehn? 2. Ich benutz APT Tool und stell da auch HCG ein und Ultramode angeklickt passt das? es gibt da auch einen Schwarzwert hab da 400 drin... es gibt da einfach keine Anleitung dazu welche Werte richtig sind...

How much does it cost, how heavy is it?

I am not even daring to ask how much it is.

The TS Optics 110/770 mm ED is listed at 6.8 kg, is that it’s true weight? The 102/714 mm weights just 4.0 kg and the 110/770 mm almost double at 6.8 kg ? Even the much bigger 125/975 mm APO weights just 7.6 kg.

Y-shape is not parallel 😅 just joking😅

Sehr brauchbare Informationen.

About a month ago I bought the cff 180 f/7. Now building my own observatory where I'll put her on a 10 micron gm3000 together with a gso 12" classic cassegrain. I'm a happy guy 😂😂

That was great information! There were answers to a number of the questions I had after I bought the camera and saw the settings it had in NINA.

Vielen Dank für die umfassenden Infos. Bis jetzt war es in Nina nicht möglich zwischen Lcg und Hcg umzuschalten. Wie man sieht ist das die neue Version, noch als Beta. Ich hoffe meine Kamera kommt von euch bald wieder und sie macht dann keine horizontalen Streifen mehr. Cs und Grüße

It absolutely drives me crazy that correctors are routinely given a 55 mm back focus. Great for a mirror less camera. Not so much with an OAG, filter wheel, and a lot of cameras.

Hi What is the mirror quality of the ONTC series? Also, that secondary mirror cell doesn't look like it's going to hold collimation well. Will it?

I have decided to order an 8” f5 ONTC. One question. I intend to get a PrimaLuce ESATTO focuser for it. Do you offer or can you recommend the right-sized tube adapter and visual back I will need to attach this focuser? Thank you! Looking forward to using this promising Newt!

Thank you for the info.

Hi, I actually have this same brand/model telescope and at normal temperatures it performs very good. However when the temperature drops below 0°C then there is a clear pinching effect. Is that the problem you are solving here? When pinched I see three dark inward spikes in a star with one large and two equally smaller. I have the tools to loosen the rear ring, but do I need to collimate after that?

starting 2024 with blowing up the prices is not good idea at all!

How is it holding up? About to get one. Enjoyed the video btw

wenn schon in Englisch, dann könnten die Untertitel zumindest in Deutsch sein!

Is it possible to keep the initial budget low to add this ts photon to a Dobson stand/rockerbox? Which one?

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

감사합니다 Az-gtix 도 적도의로 사용가능한가요?

I bought a second hand Touptek ATR3CMOS26000KPA but I got scammed, the protective glass in front of the sensor was broken. The seller had advertised it with a similar camera, but without a broken protective glass. I want to give a big shout out to TS-Optics because though I had not bought the camera from them, they were willing to send it off to the manufacturer and have it repaired! So kudos and many thanks to TS-Optics for their excellent service! g.
