The Celestron Focus Motor is an incredible upgrade for Celestron Schmidt Cassegrain, EDGE HD, RASA, and their 7" Maksutov-Cassegrain telescopes. The focuser makes for wobble-free focusing, which is extremely useful for both astrophotography and visual observing sessions. Additionally, the Motor Focus is packed full of small, but neat features including 3 different ways to power the telescope and 3 different ways to use it. The Celestron hand-controller can be used to operate the Motor Focus, the Celestron focus utility desktop program, and it is also ASCOM compatible for remote use.
The Motor Focus is a breeze to install and can be used easily with DSLR cameras and planetary cameras for use in astrophotography. This focuser has made my experience with Schmidt-Cassegrain telescopes even better, and my experiences prior to using it were already great! The ability to get a quick and accurate focus is a major benefit for a fun night under the stars.

Looks like you got a bit more serious on your channel. I love the quality of your new video. Please keep up with it. With your level of depth in videos, it will be a blast. Good review Slymin. Clear Skies!

I’m really glad that Celestron finally addressed this issue and it even added it to the hand controller! I’m disappointed that they didn’t include the 5” series because I only have a 5” Maksutov-Cassegrain NexStar 127 SLT. It’s a problem that I addressed myself too 3 years ago with an Arduino inside the mount and a small stepper motor with a gearbox that’s doing 4096 steps/cycle using only a ribbon cable with 2 buttons: +1 in speed step on each direction (up to 5) every time you’d push the same button, slow down pushing by 1 pushing the other one, or full stop by pushing them both. The precision of focus without any wobble allowed me to attach even a previously impossible 5x powermate and get it to focus while having my D-SLR at 10x on the back screen! That magnification would literally fill the screen with Jupiter or Saturn and just touching the telescope the wobble would throw it out of the screen, never to be seen again unless you’d zoom out the camera and start all over. I wish I had a focusing motor like that when I was starting! It’s a great addition to any telescope you can attach it to!! Great video and clear skies!

@marcelorsc Год назад

Hi, thank you for the review! I've read reviews that the 8SE focus has some lag when doing manually - does this lag disappear when using the motor focus?

@richardrojas6306 5 дней назад

Since I'm new in upgrades, I installed this Focuser, so I'm assuming i run the setup to get limits for the Focuser. Then I can also setup my newly installed Celestron auto align unit as well? Then I can continue setting up my 8SE scope?

Is IC Capture software just for viewing on a laptop? I’m trying to figure out astrophotography by watching RU-vid videos and reading articles on the web, yours have been especially helpful. I have a Celestron Evolution EdgeHD 8”; a Nikon D610 (I need to buy the T- Adapter and Nikon T-Ring still) and this Focus Motor. The software is still a mystery to me. Can you let me know if I can use the IC Capture software without purchasing any of The Imaging Source devices?

@hoheiyoung7208 5 лет назад

Hi Simon. Is it worth to use the focus motor with star sense and CPWI? How can you connect the motor focus with the Star sense with the Celestrn WIFI when the Celestron splitter has only two outputs. Thank you for your good videos.

@W5NWA 5 лет назад

I connected StarSense, SkySync, SkyPortal and the Focus Motor by using two AUX port splitter's (Celestron). I just did a firmware upgrade for all of them and the scope, everything registered, updated and seems to function accordingly. Hope that helps, clear sky's.

@tonyveroni3600 2 года назад

@LiquidtravelPhotography 4 года назад

Question for you. If you ever have to transport this scope, do you leave the focus motor on the OTA or do you remove it and replace each time you travel? I am trying to figure out a carry system for all my gear and I just got the focus motor and was curious the best way to transport the OTA with the focus motor attached. Normally I use the foam that came with the OTA but now that I am putting on the focus motor, I need to rethink how I do this. Thanks in advance.

@AstroBlender 4 года назад

I keep mine on. You could cut a slot for it into your foam, or just put it into a separate carrying case with pluck foam.

@clockman9097 3 года назад

Hello there. Do you know if the ZWO slim OAG will work with the focuser on the Evolution 6? The specs say that the Celestron brand OAG isn't compatible due to mechanical interference. Thanks!

@jameslyons3306 3 года назад

Hi. Good video so thx for that. Just getting into astrophotography and I'm curious. Will this focuser work thru Ascom say, in SharpCap, where the s/w will create a curve during analysis of the focus?

@angelodecesare5814 4 года назад

hi, thank you , I have a question , if I add the sky portal, wifi, and disconnect the handset (apparently they conflict), can I control the focuser with sky portal app? then if you can't, it would mean you couldn't have them both simultaneously !?

@phmuller 3 года назад

Cody, would any RJ12 AUX cable work with the Hand Controller or do I need Celestron branded?

@kurtjohnson4601 5 месяцев назад

I have to add that I use this on my CPC1100. It has built in backlash for the mirror flip. And I use the focuser ap on my laptop. I watch as the object moves off to the side as it focuses. Then as it comes back into view, it puts the object right back to center, every time. Always backing out the mirror and turning it in accounting for gravity. Even for a small focus correction. I rarely use the manual correction. I just put in the number and let it go. Works every time. Very nice focus motor.

@denodan 4 года назад

I have the latest firmware and dont see focus motor in Nextstar + HC. does this menu only come on when you have the focuser motor installed? I have a motor coming, but don't see focuser in menu?

@plymouth5714 7 месяцев назад

I've just bought the focus motor for my 6SE but haven't fitted it on yet. I did manage to finally get the celestron updater to work but cannot find any reference to the focus menu on the handset. Just wondering if the focusser has to be physically plugged into the aux socket when updating so the program can detect it and download the relevant software to the handset?

@skydvr69 4 года назад

Does adding the focuser make the telescope unusable without power? IOW, manual focusing is impossible once the motorized focuser is installed, correct? I sometimes use the scope unpowered, so I just wanted to verify that this is not a practical option for me... Thanks.

@johnpatterson6205 5 лет назад

The one thing I learned by using mine is power. If you intend to use the focus motor using the USB cord you would be wise to buy an AC powered USB hub. It attaches to a USB port on your laptop and plugs into 120 vac. This will provide enough power to run the focuser, especially if you are also running other USB connected devices. I run my ZWO ASI294MC camera, focuser, and StarSense and running each of those with its own power connected to it makes a huge difference in performance. In fact, if the focuser's amperage is insufficient by just a little bit, it will not focus. I built a battery box with USB powered ports, a 12V cigarette lighter socket and binding posts. I connect a DC to AC inverter to the binding posts to run my laptop and powered USB hub.

@kurtjohnson4601 5 месяцев назад

Agreed, I had to add the AC adapter to power it separate from laptop and USB. I use the printer port for comm with laptop.

@BrotherAlan 2 года назад

Wish Celestron offered their SCs with the focuser built it in, call it the DX model. Ive been using a 8se and focusing is a pain, my best focus comes out soft. For astrophotogrphy this is a must. Looks like I'll be getting one of these.

@chazpatr1 4 года назад

After viewing this review I ordered the focuser when I ordered my 8SE. Installed it and have found it VERY difficult to use with the hand controller. When you need to use the other functions you have to escape focuser control just to use the mount direction controls. It would make more sense to set the focuser to the setting with the mount direction controls still active but it stops them from working when you need to tweak or when changing eyepieces. It was so frustrating I had to uninstall it. I know there's a way to use via SkyPortal etc but it still takes more juggling for s simple tweak. Is there any way to use a seperate hand control to focus? Any one know of a device that will work?

@upnorthoffcuts929 2 года назад

Thanks for the video. One question, do you still need to use a bahtinov mask with the 8se for deep sky?

@randyburton2559 3 года назад

Would you suggest how you power your 8" SLT in the field? I'm trying to decide whether to get a SLT or the Evo 8" but am wondering if I'm going to need a field battery regardless. If that is the case. It would make the decision much easier.

@astronomylivestream 5 лет назад

Your right... I ordered the Celestron 11” RASA (CGX-L) last October and it’s still in the box. Clouds, rain, snow and a even blizzard last week. The RASA 11” is about as big and weighs as much as a C-14. Not something you just slap on a mount and off you go. Excellent tutorial! A saver and share. BTW, I’ve been using a clothespin on the focus knob for years. No image wiggle and I can do a fine focus. I’ve been waiting for somebody to do a review on this focused. Just order it! Again, you did a great review and tutorial. I have no questions and sub to your channel.

@AstroBlender 5 лет назад

Thanks! Enjoy your 11" RASA! I've seen some pretty amazing work with them!

@astronomylivestream 5 лет назад

i was wondering and asking permission, if I can use the 3 videos that you made on the motor focus during one of my live streams. I'm going to live stream installing the motor focus onto a c-8.

One of the items you use in this video is the "Celestron Skyris Filter Wheel", but it isn't listed on Celestron site or seems to be available anymore. Is it absolutely necessary or is there another alternative or upgrade to it? Thank you for the informative videos you post.

Hi, thanks for another great informative video, Slymin. Due to mobility issues, I am hoping to do most of my telescope viewing (9.25 SCT) on my laptop. To that end, I am going to purchase a Celestrom NexImage camera. I understand you can then link your hand controller to your laptop via NexRemote on your laptop. But what focussing the image on my laptop? Do I need the Focus Motor linked to my laptop to do this or can I focus vie the NexRemote? Any help / advice greatly appreciated, thanks.

@SmokinAcesUSA 4 года назад

Hello I own a Celestron 8se and just bought a ZWO camera. I'm attaching the eyepiece first and using the auto focus and then replacing the eyepiece with the camera but I can see anything. Do I need to buy something I think is called T2 adapter or should I use the auto focus instead? plus, I see a lot of guide scope with mini zwo camera attached at the end of it, is it necessary?

@QuillionPKR 4 года назад

Great video as always Slymin, loving your work. Im new to astronomy and am still finding my feet with my 8SE. I am interested in the Focus Motor but currectly have the Wifi dongle and the Star Sense connected via an Aux splitter. How do you power your 8SE and your Focus Motor? I'm perhaps thinking of either buying another splitter to give me 3 ports or another Celestron battery pack. Thanks!

@AstroBlender 4 года назад

You could run your Focus Motor through USB, but that would kind of defeat the purpose of your Wi-Fi ability. I usually run my Focus Motor through the 8 SE without the SkyPortal Wi-Fi link.

Fortunately, the Sky Portal software has a focus control on it, but it can be very tedious getting focus with it. Signed Struggling with this.

@kumarmvnk3654 4 года назад

So what Motor focuser is recommended for the SCT ASTROFI 5" Telescope ????

@JohnMcGFrance 4 года назад

Thanks for the review. I have this on my Edge8 and as long as I have my laptop I’m fine, but I don’t have a Celestron mount so no hand controller. This means if I want to just pop out and do some visual work then I have no way to move the focus motor. I really think a hand controller is essential if you’re mainly into visual. I’m mainly imaging so not a big issue for me but it might put some non-Celestron mount owners off. Other than that it’s great.

@tonypegler9080 Год назад

Make sure the focuser is pluggged into the AUX port. If you also have Starsense, that needs to also be plugged into AUX port so you will need a splitter. I found the hand controller would not see either the focuser or starsense if they were plugged into the Auto Guide port.

@canyonblue737-8 5 лет назад

Do you have difficulty taking your Baader Clicklock visual back off and on? the lock nub hits the motor focuser, it seems it only worked for you because you installed the motor after the baader was already on, but I would think you couldn't get it off without removing the motor...

@AstroBlender 5 лет назад

Hi David, You're correct, I cannot remove my Baader ClickLock visual back unless I first remove the focus motor. Removing the focus motor takes no time at all for me though, so I don't mind.

So, still a MYSTERY. I use the Celestron SkyPortal App to control the auto focuser. I callibrated it per instructions. Round and round it went, till it finally stopped. Now, WHAT EXACTLY DO THE NUMBERS ON THE APP MEAN, SPECIFIC TO THE AUTO FOCUSER? And, finally, why doesn't the autofocuser adjust itself to "near focus" after calibrating. It's difficult trying to find initial focus.

@Dragonblaster1 3 года назад

@michaeledmonds3027 2 года назад

I really like your instructional videos; you have a gift for teaching. Also, your camera work is smooth and tight. Question please: I have a Celestron Evolution 6" and want to add a motorized focuser. I see from this video that the 94155A unit will clear the mount base at zenith. I also am interested in the ZWO EAF, but it requires a Buckeyestargazer printed adapter and would stick out a good 100mm from the back of my sct. I have a ZWO 183MC camera and a ASIAIR Plus controler ordered, so the EAF would work remotely with a tablet, but I fear it might hit the base at zenith. I also have read that the 94155A has to be left slightly loose or it can bind during operation. So.....finally the question: What should I use for a focuser? Thanks for your advice, Michael

@davidhash1281 5 лет назад

@AstroBlender 4 года назад

Mark, I've had significant expeirinece with the CPC series, and it is phenomenal! You'll love it! I would just focus on getting the star alignment down - it is really easy. Just follow the instruction manual. There are different ways to do it, but usually 3-star or two-star alignment will give you the best results. I would hold off on a focus motor for the time being. I didn't get my first focuser until about 7 years after I started! I'd just focus on the basics now and enjoy your telescope. A couple months from now, after several nights out, you'll start getting a feel for what you want to improve or upgrade. Some good eyepieces do go a long way! Explore Scientific 52 or 68 degree eyepieces may be a great choice for you on your new 11" SCT. Congrats and clear skies!

AstroBlender thank you for the advice. I’ve done the 2 and 3 star alignment in the past 3 nights. I’m getting the feel for using it. I still don’t understand eyepiece use with a Barlow and when I should use the silver (extensions?) that screw onto the eyepieces. I would like to see the moon with more detail and eventually get into photos. Can you ad any other eyepiece suggestions?

Sorry, but there is no need to worry if the camera is upside down. In space that condition does not exist. It doesn't matter what orientation is used the object will look right regardless. So any camera angle works just fine. The only issue, is the output screen may be upside down and therefore hard to see the object.

Why do you need a focuser once the focus is set????

@banpowel9784 5 лет назад

Is there a huge difference between the 4se and 8se, unfortunitely my funds only stretch to a 4se.

@TheTNTerminator 5 лет назад

Yes, the 4se is a great scope but only 4 inches of aperture and is a Maksutov Cassegrain, whereas the 8se is 8 inch aperture and is a Scmidtt Cassegrain

@AstroBlender 5 лет назад

The 4 SE was my first telescope I ever used, and it is great for the planets, some stars and double-stars, and some globular clusters. It is really portable and a great telescope for camping. I quickly learned I needed more aperture though.

great video but where are the links?

@jesusfrk86 6 месяцев назад

Yeah mine kept over focusing and when i tried to manually focus it it would focus and then move back out of focus. But thats in the app i have not tried using the controller.

So, i bought this for my C6 and on german retailers there is NO WARNING that it is not usable with a C6 and 2" equipment or reducers at all. The mounting ring in the correct rotation fits but blocks 2" / reducers completly. If you rotate that ring 180° (the open part of it is on the baffle tube side) makes 2" / reducer gear usable BUT the screw holes are not fitting / are not in the correct place. Not sure how this could happen. I mean - seriously. HOW?! It took me 10s to see that this will not work out well if you want to use a reducer OR 2" gear to switch your setups quickly. I use three setups on my C6: 1. 2x f6.3 reducer to get a f4.0 EAA canon that works well. 2. 2" Baader click lock + Starizona II reducer for AP use 3. 2" -> 1,25" Baader click lock for visual, lunar and planetary AP use Solutions? RMA it and get the money back OR drill holes in it to make it fit ( what i will not do - not my job after 300€ on that thing ). I am really disappointed.

Only thing I question is 900mA through USB 5v (4.5Watts), or 1000mA through 12v (12Watts). Significant power difference.

@UNSCPILOT 4 года назад

It likely just runs slower in USB mode to compensate for the lack of power

@Ecleido75 5 лет назад

hello, does this focuser eliminate the mirror shift?

@kurtjohnson4601 5 месяцев назад

No, it uses backlash settings to bring object back into view.

@hayoung750 5 лет назад

thanks for your video. i bought same telescope 1 month ago.

You're welcome!

I've been eyeing up the 7inch mak also. Orion sells 1 that's just the ota and comes ready plummed for sct accessories. I haven't seen any reviews for either brands as of yet.. Anyway great video!

@AstroBlender 5 лет назад

Thanks, I appreciate it! It looks like High Point Scientific sells Celestron's 7" Mak by itself, without a mount, so there is that option too. I really like that they have standard SCT threaded rear cells now. I am primarily interested in planetary photography and globular star clusters, so I really have been wanting to get one to see what they can do.

@ericemanuelson5128 5 лет назад

Idk if you're seen but high point scientific has a celestron 7inch mak ota demo from neaf for sale with a good discount.
