I've got the original NBZ filter which I used with a RASA 11 & it still performs well so never bothered with UHS filter, although this one may be another one I may purchase at some point, cheers & clear skies

Hi Cody . Did I hear correctly...no halos ? I was hoping you might post an image showing that . Next time eh ? Cheers .

Nice.

Well, I tried installing the motor today and a couple of things as regards to the Celestron 6SE.: 1) The cover plate screws are 5/16 hexagonal screws, not Philips screws. The philip screw supplied is not going to work. 2) I had issues with installing the cover plate. No matter if I set the scope pointing down and snugging it, it tilts and binds. I ended up stripping the gears. The good thing is I had a loss prevention plan so I'll get a replacement and I'll get longer hexagonal screws since the original screws are too short.

Picking mine up next week! Trading in my rig. Which cost way more, and provides rather less.

I recently bought a Celestron Focus Motor for a C8 SCT and when I went to install the new orange focus plate, the screws I removed from the original one don't fit. They're too wide at the top to go into the recessed area for the screw head leaving the screw too short to come out the other side of the new focus plate. And even if they weren't too wide at the top, that would only leave 2 mm or so to protrude out the other side. Does anyone know what size screw I need to look for at a local hardware store? Has anyone else run into this before?

Just starting to watch this and it's amazing, but will it work with a CGEM-I mount??

Focuser is soft and squishy. OK. What do you do instead? Do you just live with it?

Hi.. thanks for the valuable info. I was in the process of installing my focus motor adapter plate to the back of my SCT. Noticed the adapter plate does not sit flush to the back of the OTA and there is a gap. Correct me if I am wrong but your adapter plate looks flush to the OTA. Just wondering if the focus motor adapter plate is recessed like the stock focuser plate.

Actually, it’s not called star census actually called CELESTRON nextar + system you might’ve accidentally named the wrong series of telescopes

I like the precision given for the backfocus lenght when you have some optical knowlegde background. The precision for focusig is so inacurate on this telescope it needs a reducer mechanism Celestron has made for astrophotography. None of the C8s will get this backfocus value. . The collimation by the secondary can change by 0.1mm the distance to primary. 0.1mm is tiny, but the secondary is multiplying the modification . Therfore the backfocus will change by 0.5 mm . The primary will have to move and therefore the backfocus at the back of the telescope will change . Oslo free version , is very uselfull to simulate where the focal plan is. What is important is to start from this reference given for Celestron but it is not so critical. because what will change is the focal lengt of the SCT . What you have to remember there is tolerance for the Airy spot position 0.1mm . The danger is touching the secondary mirror very critical for the aligment of the optical system. The HD is based on an aspherical secondary , a the Schmidt Blade with different radius the air space doublet. This solution is to keep a short tube to correct bur the Coma the Chromatisme and spherical aberrations will be inside the AirySpot up to 14mm of the axis . But also to change the the Petzval sum for flatening the focus plan. A very good telescope. The reducer 0.7 requires another focus position of the SCT to let the final sharp image at the correct backfocus of the reducer. This means the primary will have to go fowards ( this increases the focal length) It is wise to analyse the picture of this focal plane given by the SCT .I f you can put the Cmos at this position you should evaluate its quality . Some time C8 owners are complaining about oval stars at the edge of the Cmos camera. In fact the primary mirror can have some tilt for some positions enougt to modify too much the optical path and to create oval stars. .. Blocking the primary helps but this doesnt eliminate the tilt which can be to 60 to 100 microns at the edge of the mirror! In an optical instrument every detail is important. The theory is one parameter. And Celestron has a commercial policy to sale telescope for a price tag. Celestron can't sell a perfect SCT ...

The coloring of one side blue, one side red on the white stars is disappointing.

What affects can I expect in a 14 in dob? Or is it even needed with all the light it gathers on it own?

👍👍👍👍👍👍👍

Thanks for a thoughtful, honest review. Keep up the good work. Cheers, Des

Thanks for the review Cody!👍Here are a few of my opinions: 1. It's nice to see a fast scope with reducer that appears to illuminate a 44mm circle without brutal amounts of vignetting! And, yes, it is a very user-friendly package! 2. It's unfortunate that the reducer introduces a lot of colour error. I have a hunch that it has no extra low dispersion glass in it. 3. IMHO, you were dealing with some tilt in the system, because the parts of the field with distorted stars changed after you added the reducer to the system. 4. FWIW, we need to keep in mind that the ZWO 2600 MC duo has 3.76um pixels, while the Canon R8 has 6.00um pixels. That means the test of the optics with a full frame sensor was much more forgiving than it would be with, say, an IMX455 sensor, e.g. ZWO 6200MM or 6200MC camera. The IMX410 sensor (e.g. ZWO 2400MC) has pixels which are similar in size to the R8, so those who are happy with the resolution & performance in your test with the R8 may want to consider using an IMX410 based camera over an IMX455 based cam. 5. Generally, the saying 'you get what you pay for' does apply to telescope optics, and the fact that the Founder Optics Draco 62 is just a bit more than half the price of the William Optics Pleiades 68 is reinforced by your carefully done, thorough testing. The Pleiades 68 has similar specs to the Draco when the Draco reducer is used, and I do not recall seeing any examples of the f3.8 Pleiades 68 producing colour error like we saw from the Draco at f3.9.

I won't even test anything less than an octuplet refractor!

hey cody you have great videos. can you do a video on the wedge for celestron 8se. I've seen other ones and they really don't help please. thanks in advance

Hello and thanks for your video. I saw you using this scope on a SCT. But your closing sentence states it would be suitable for short focal length telescopes. Do you think it would suit a celestron C8 Ota?

Very good video presentation. But a word of caution. For tracking purposes this scope's tripod and mount are not good near the equator, The single arm would have to be pointing near the horizon to have it polar aligned, basically level with the ground, and the mount cannot be configured that way. I have a Nexstar8i, three degrees south of the equator, so, no polar alignment for me.

Very helpful video. Question, How did you install the IR-Cut filter to the ASI174MM Mini? I purchased the ZWO D25 IR-Cut prote window. But the only way I can see to install it is to remove the existing window. But it is glued in place! Thanks.

If it has horizontal and vertical motors, why would you need to put it in equatorial mode?

Hi, my problem with this cooled OSC 183 is the strong horizontal banding clearly visible on the photos after the usual calibration with flats, darks and DF. What could be possibly go wrong ?

Another excellent review. Thanks. Do you have any experience to share concerning IDAS SHO UHS filters for f2 systems? Cheers, Des

Like the model collection in the background!

👍👍👍👍👍👍👍

Nice filter drawer.

We have almost the same LEGO models, except for the big Saturn V model (off-screen somewhere?)!

Apologies for the motion blur - I am investigating my camera settings to see why this occurred and get it corrected. EDIT: Problem fixed. This will not be an issue in the future!

For information I measured the motor noise level of the C8 Evolution HD with alt-az mount: about 50dB at 10 m, which for me is too high for respecting the sleep of neighbours.

I tried it with three different system. Not a single one of them is able to open the jar file. Why does Celestron use a such uncommon file type?!

Damn it, RTFM 🤣 i just do always a minimun alignment with 2 stars... i just not read the AVX manual to go back to home for the ASI air. Thanks for your hint, so now i will do so! Good job!

For my 8SE, do I need to manually set the focus L-R or center? Or, does it even matter? Thanks.

I heard backyard Eos for the laptop, whats the camera you use ? I've seen some weird / shitty Amazon stuff and it's kinda hard to cgoose. I'm fine uaing my phone but laptops kind of end game as it were, so I want something banging for a laptop camera.

Excellent video-and the limited edition is so cool, matching diagonal too! Does the special plaque state what number of the 600 produced yours is? 13:52 one of the neatest images of Copernicus I’ve seen :-)

With a guiding error of 0.8 to 0.9. Is that still less than your pixel scale with such long focal length to get sharp stars? What camera did you test this with please?

Very helpful video. Thank you. As a newbie who just setup a new Edge 8 HD I have been anxious to setup Starsense and get out and try it out. Clear weather this week so I should be good to go. Your video helped me a lot and it seems less intimidating now.

Thank you Simon. I bought an adaptor and followed your instructions. My Celestron Evo 8 is now up to date! I had loads of issues with crashes and slewing and other little bugs. Now it's time to go outside and see if this has actually solved those...

Nice video. I have enjoyed my 183MC Pro so I bought the mono version last fall. I did a narrowband shot of the Heart Nebula last fall and noticed a grid pattern. I think it may be from the Ha and SII flats. Have you noticed this at all and if so what can be done to minimize this? Thanks, Tom

I just got an asiair and I got everything working the first night out. However my autoguiding wasnt so great. This turorial answered alot of questions I had and improved my guiding the next time I went out. Thanks, subscribed

Brilliant thank you Cody, very helpful 👍👍👍👍

This mount is only good for visual use it had always a lot of backlash and other problems which made me very unhappy, for photographic better use Skywatcher EQ6R which does the job

Why wouldn't that somehow work with the Celestron 4se?

Any chance you can make a video on how to then take photos and get focused with this setup? I try and do live view and I can’t see anything from my screen and when I take photos I don’t see anything. I’m ready to give up

What’s the numbers on the back of the red cat towards the camera? Does turning it do something?

Thank you so much! From a retired Electronics Technician. I’ve been a Mac user for the past 30 years and with limited Windows usage I’ve been able to avoid the platform until I took an interest in astronomy. Anyway, your videos are very helpful and in this case allowed me to “Easily” update the firmware packages for my Evo9.25, Hand controllers and Star Sense. Keep up the good work.

Great video! Did you make the video when you use the reducer? Thank you

I'm looking at this scope but don't quite understand why you think the sensor is a good choice. It's low res and large pixel size, basically like two year old sensor, right? Can you explain why you think it's actually the right sensor further please? How do you know it's a well designed or simple app? No one has used it and you say a smartly designed app is a big advantage.

Why did you add noise to your audio track. Explain how, adding background noise makes easy to hear what you are saying?

Dude. You are such a wonderful teacher. I am a 47 year old man in 🇦🇺 and I was schooled…so interesting. I now have so much more interest in the hobby. Exciting
