Nice video. I noticed that one of the small washers (grommet ring) went out of place when you were showing it to us at 11:50. In the video, you subsequently installed the metal ring on top without realigning the grommet ring. Just thought you should know, in case it’s not been corrected later. Cheers.
Thanks for this video Dave. I have the 8in Quattro and have had the same slipping at times. It is able to tighten up o.k. for my image train. I really like the f4 speed of the optics. Cs Ray
Hi Dave! Thanks for this video! Recently I have also purchased this focuser. It is mounted but I have no idea how to properly adjust the focuser to the optical tube. Maybe you could do a brief video how you have managed to get the focuser into the right position. Thank you very much!
First.. Great video on that Focuser... I would agree it 100% better than the stock unit. But this has always been a concern with anything made in China? Don't think you said the total cost $200 ish and worth it. Now how will it perform with the EAF and NINA? How will it work a year or 2 later, these are unknown. But I do like the lower costing focusers for A.P imaging but the quality is a concern... Please do a longer video, no quickly on the adjustments, please...As always thank you!!
Yes, I was wondering about the quality as well. It is not a Feathertouch, but the build quality appears to be sufficient. I will not really know until I have tried it out after a season or two. I could do a teardown of the focuser and see how it is constructed, and I might still do that if I find the time this summer. It is really hard to find a focuser for this size telescope. I wanted to put on an Esatto 2" focuser, but they only have adapters for the Quattro 200P and the 250P. So, this was one of my only options. I still might pick up an Esatto for my 10" Newt, but that would be a later addition if I decide I need it. CS!
Interesting video … I’m not sure that old one even makes a good visual focuser. How do you think this new one would work for visual use? The knobs look like gear teeth - are they comfortable? And is there any backlash? Seems attractive to retain the tilt mechanism and original base.
I've gotta say Skywatcher Crayfords are poor at best & I upgraded mine although at the time I couldn't find any rack & pinion focusers in my budget so went with another generic crayford which is miles better & holds my camera just fine. Interestingly enough I bought the same kit for my other halfs 150 PDS but i found the mirror mask to be to big as it doesn't hide the clips so I never fitted it in the end unless I'm missing something of course.

Hi Dave, so what do you think of the CYCK Universal Telescope Focuser? When you unthread that blue compression adapter thread size M48 or M54? Thanks! Found out the thread is a 54mm 0.75 pitch..
I did this mod last summer. EAF focusing is 100x better than with the stock focuser especially with heavier loads. Have you found a solution for replacing the clamping ring at the top though? It’s kind of janky and can be difficult to tighten/loosen in the cold.
I got a compression ring from First Light Optics in the UK, and I plan on using it. I don't feel comfortable with the blue ring that comes with the focuser; it looks too sketchy to me, LOL!
The clamping ring is perfect as long as you keep the hex nut glued in place and the washers. Buying a 50$ compression ring from F L O is a complete waste of money in this case.
I've noticed that people upgrade the spider vanes on the secondary and add a mirror clip mask on the Quattro 150P, do these upgrades need ( or should?) be done on the other Quattro models ?
Great question. I don't have any experience with the Quattro 8 or 10 inch Newts, so I can't say. I do know that a mirror mask is always a good idea, but as for the spiders, I think it depends on whether the mask is sufficient to hold the secondary mirror without any flexure. The 6" Quattro's are known for their flimsy spiders, so I replaced mine to avoid having to do that later. CS!
No, it has been too hot here in Phoenix to shoot. Once it cools down a bit I'll do first light and work out the kinks and report back on the focuser. I am curious to see how much backlash there might be. CS!
@@DaveUrbanAstro I ordered one hoping the china speed pack gets here soon. I had an omegon short focuser sort of similar design loved it except for one thing the constant sliding the inner focus extension piece drove me enough to return it for this one
It depends on your use case. If you are doing visual, then it is sufficent. If you are just putting on a small camera like the 294 or 183, it is most likely sufficent. But if you have a large camera like the 2600 series from ZWO and a filter wheel and a rotator, then it gets pretty heavy and the focuser just isn't up to the job. Again, it depends on what you put on it.
Looks a very worthwhile upgrade and well made piece of kit.

Yup, I saw that when I was reviewing the video and went back and corrected it. Thanks for the catch!

Great video :)
I would love to see a follow up where you adjust the tilt!
Yup, it is in the works. I am planning on first light in July (weather permitting), so that is on my to-do list, and I will do a video of the process.
@@DavidCotePhotographylooking forward to it :)
I've been eyeing that focuser on eBay for my Skywatcher 12" dob. Thanks for posting this.
Installed it on my SW350P Dobsonian, used it, and it's smooth. I already posted a Saturn image online.

How do you replace a focuser on an odd size telescope like a 13.1 in mirror?

@@DaveUrbanAstro ty for the answer. Dont have or plan to have more than a imx533 cooled camera and filter drawer so i should be ok
