If you want low power/wide fields with your C9.25, get a 41mm Panoptic. Works great, it's one of my favorite EPs for larger objects. On a GOTO alt-az mount it's a bit lighter. No counterweight needed. I remember when all the Celestron SCTs were orange.

After using Polaris as North and a 2 star align the AZ mount that comes with it will put deep space objects in the eyepiece every time, it puts planets almost in the eyepiece and it tracks very well for visual keeping an object in the eyepiece for hours. It was the most I could afford and I take it outside in parts, tripod & head, scope then all the small items, eyepieces, battery and controller.]

Hi Ed - great to see you in "live action" after reading your reviews for many years. One point worth mentioning about the C9.25 is that it is the largest SCT that will fit on Celestron's Evolution alt-az single arm mount, albeit with a beefier tripod. The advantages of that mount vs similarly-rated equatorials are weight (because no counter), compactness (built in battery), and ease-of-setup and alignment. With my Evo 8 I move the entire scope/mount as a unit without difficulty, so I've been considering bumping up to the 9.25 I wonder if it would almost -- almost -- qualify is the largest grab-and-go scope feasible? Looking forward to more reviews!

@herbpowell343 2 жыл бұрын

Thanks: The specs suggested the 9.25 was the limit for that mount, but manual specs do not necessarily conform to typical users under typical conditions, so it was nice to get that confirmed. A solid decades effort finally convinced the wife we should upgrade from Firstscope 114EQ to an SCT twice as large, but dropping the full price of an 11" or 14" all at once would be expecting too much, so I'm taking a good hard look at which mounts can handle which OTAs down the line.

@k.h.1587 9 күн бұрын

Ive seen black tube 9.25 with the focuser counter, iirc the fork we pulled it off had the byers drive. Don Rothman was still in business at the time and he drove down the hill to buy the forks, wedge and tripod. Then my friend got in a minor car accident and decided to sell the tube to pay for the damage. It was pretty good, but i liked the c11 i got later on better, it was a good specimen and the extra aperture helps

@ericemanuelson5128 3 жыл бұрын

My new favorite telescope is the Orion starblast 6i although it could use a better focuser. I like that i can use it with or without doing alignment and the optics are much better than i was expecting. Also it's quiet compared to my 8se even though I do use the 8 on a manual mount too. It's funny you mentioned a 80mm refractor to compliment an sct. I just ordered an Orion goscope 80mm tabletop refractor at f4.3 as some nights I want low power then high power and removing the reducer back and forth is not much fun and using my newt in winter isn't an option as I found out with my now former 10inch skyline dob a great scope but took up too much space for only getting limited use.

I own two Celestron 9.25 among my telescopes. The first I bought w/SGT mount. My second was an OTA, which was on sale at the time. These are amazing OTA for the price. Anyone who wants to buy an intermediate scope between 6" and 10" or 12" should consider a Celestron 9.25 SCT. I remember how Saturn appeared under high power and a 3X Barlow lens. It was amazing. I even favor it to the C8.

Hey Ed, thanks for the great video. I just picked up a Celestron 9.25 a couple days ago -- I had an Orion XT10i Dob for years, but it was time to do more astrophotography. I have a Canon T5i, but now that I'm so automated on my 9.25 with GoTo and Tracking and with 'SkyPortal', I'd like to get a camera which I can also control from inside the nice warm house too. I know Celestron makes a couple planetary cameras which can plug into an Aux port - but if you have (or could do) a video on remote controllable cameras, that would be great.

I use a Baader Click-lock 2” visual back, dew shield, and the Celestron.6 reducer/corrector. Also, I can’t function without a Telrad. I roll it out on a Scopebuggy when I use it at home.

Condolences on the 125 PE. I used to be all EQ, c11 on g11, and meade 8 on gm8 or cg5. It is definitely the better way to go. I now have fork mounted C8 and meade 10, mid 80s c8 and 1991 lx premiere 10. That 10 is a beast to set up and I only used it a few times. I got a ripping deal, like $200 from a friend on the C8, and another friend traded me the 10" straight across for the g11 tripod and counterweights that the tweaker storage theives didn't know to steal when they got everything else. It was the only way I could get back into scopes of that type because insurance found a loophole to not pay a dime, and I am on disability. The only way I could afford the other scopes was from working at a dealer before becoming disabled, since dealers pay less for used equipment, and also get to take advantage of clearances, blowouts and sales in general, the employee discount can be quite substantial.

I have a C9.25 on a CGEMII. I struggle with the weight of it (schlepping into garage after using). The smartest thing I did was to be the StarSense camera and hand control and a 2" visual back and better eyepieces. Beautiful views through this scope, but just ordered a smaller refractor for AP. If I had a wish list, at the top (after my own observatory) would be easier to follow, truly thorough information from Celestron, QHY, and all the software programs. This hobby will certainly keep your mind engaged and if you love solving puzzles, it's perfect!

@ronboe6325 3 жыл бұрын

I was really wanting one of these at one time; but knowing what I know now - not so much. But I only know that because of the scopes I've had over the years (and changing priorities at a scope). I think most folks starting out are like me when I started out - only very vague idea of what we want to do. You over research, get the "wrong" scope anyway. It's like pinning the tail on the donkey. Just get a scope, use it, see what works and what doesn't (hopefully with out spending too much money) and then make adjustments from there. If you are a bit careful, what ever your first scope is, it will still be useful; but your main scope might be something else. Gawd help us on eye pieces! LOL

@bhuwanjangid1886 3 жыл бұрын

One more reason the c9.25 has a great fan following is that because of the slightly higher f ratio there is lower spherical aberration compared to an f/2. There is a reason almost all of the professional research grade catadioptrics have primary mirrors in the f/3-f/3.5 ballpark. The resaon for these SCT’s having fast primaries owes to the fact that they were made for amateurs who value portability. This different is kind of gone with the edge hd as it already has a field corrector for SA. BTW it is my childhood dream to meet you someday :)

@clueck1948 3 жыл бұрын

I sure enjoy your videos and explanations. I am still in the beginning stages of deciding what type of telescope would work for me best. The differences between types of scopes, the glass, the focal lengths, the size of the object viewable thru the scope; it’s fascinating and complex. I envision a mid priced scope for me and initially thought a refractor would be best but now I am not sure. The collimation bothers me in the mirror telescopes but perhaps it isn’t that big of a deal once you start using that type of telescope. I’ll keep watching videos and some day make a decision. Thanks again for your informative and entertaining videos.

I downsized from a 10” Dob to an Edge HD 9.25. Some have claimed that for visual there is no difference between the “standard” 9.25 and the Edge. My eyes tell me different, though. With the .7 reducer I get a true field of 1.5 degrees with a Pentax 40 eyepiece (measured using drift timing). I can just barely get the double cluster in that 1.5 degree field. Pinpoint stars clean to the edge with a tiny bit of vignetting in the last 5% or so. However mag 9 stars are still visible in the vignetted area.. I also have a C8 XLT. While the C8 is great for EAA, when using the scope for “visual through the eyepiece” I’ve always found the views through it somewhat soft - even with the .63 reducer/corrector.

As for the proper mount question, i would say the GM8, since it started life as the celestron G9, intended for the 9.25. But i would prefer to use a g11 or eq6. I never had a 9.25 personally, but many people i knew did, on the cg5 mounts, and it was borderline at best but still usable. I used an 8" lx200R on GM8 and CG5 and that was rock solid, and a C11 on a G11 that was also rock solid. I remember back in the day you could get 11s and 9.25s on the non goto version of the cg5 for LESS than the OTA only price, and that was how the dealer i worked for ordered them, and separated them into mounts and OTAs rather than ordering OTAs and mounts a la carte. I didn't know that first and caught an earful for sending a drop ship order to celestron for a CGE a customer ordered. Barely enough profit margin to cover operating costs when done that way. It was also funny when our local televue rep ordered a cge direct from celestron for the industry insider price, and it turned out we could have saved him A LOT of money had he bought one from us at employee pricing from one that was ordered as a package with the ota and then split up. I miss that 5 year period in my life, almost as much as i miss all those scopes i used to own.

I mainly look at planets and whatever galaxies or clusters are visible in my area. I have two questions.

Second, would you have any specific recommendations for good eyepieces around $100 in those sizes? Thank you so much in advance. All the best. Mike

It really seems like the 8" is the one to get if you want a reasonable to handle portable scope and the 9.25 can be moved, but it's not as casual a thing to do it. So it would be good as a personal observatory scope that you could take to the occasional multi-night star party and not have to be a weight lifter.

@atarkus8 3 жыл бұрын

As a C9 owner I can tell you that they definitely aren't all created equal. For example, one thing you'll notice on the different generations is the amount of mirror flop. On my pretty old made in USA model it's really negligible, but on a friend's newer Chinese model it was significant. There's also a very obvious difference in coatings, and hence contrast. The old "starbright" coatings on mine are not that great. The newer coatings are far superior. On the other hand the optics on mine are simply incredible, but I've looked through other C9s that are just "ok". If I remember correctly there was also a brief period where they made carbon fiber tubes. And I've heard that surprisingly the optics in those were somehow worse. Supposedly the Edge HD versions are the excellent, though you could argue it's a whole other telescope, and I've never had a chance to look at the two side by side.

I have a G11. I mount my old C8 with iron clamshells and I use two Los plates, the second one mounts a William Optics G71 as the guide scope which is far better then the OAG I first tried. The assembly is about 140lgs but it is VERY strong. The G11 breaks down into 3 pieces so my setup is about as big as one can go and still be portable in my opinion. My thought is do I want to replace my C8 with a 9.25 Edge HD? Not sure if it’s worth all the expense. It’s just chasing some holy grail.

Buy a HyperStar for the C6 and it will become your favorite scope 🙂 I know you cant do visual with a HyperStar but paired with the right camera, taking pictures at F2 is amazing! Imagine 300mm at F2! Perfect portable EAA rig! See that F2 mirror is not so bad after all 😀

What was the optical tube cool down times of the 9.25 , 11 and 14 ? I used to own a 16" LX200 Meade and it took forever to cool down. I'd like a comparison of those 3 celestrons if you happen to remember.

Don't forget if you want to vary the effective focal length using the reducer, you can reduce the focal ratio of the telescope further by moving the eyepiece or sensor a little further from the reducer. It then changes from an f/6.3 to f/5.5 (for example), and then refocusing. The opposite effect is true of a Barlow.

@k.h.1587 9 күн бұрын

But the .63 reducer does not perform as well when not used at the designed back focus distance

@offraed6156 8 күн бұрын

@@k.h.1587 That's right. There will be a modest visible increase in some aberrations, just as there is when a Barlow is used at different positions other than that it was designed for. Slight trade offs for usefulness. More noticeable with off-axis aberrations in the case of a reducer. If your object of interest is center field, it should be less of an issue.

Been looking into getting a Evo 9.25. i have no qualms with bringing it out and in in pieces. I'd have to do that with pretty much any telescope I have, since I live in a mobile home, which sits a couple feet off the ground and have to take a small flight of stairs in and out. Plus, I love doing a lot of planetary observations, which this telescope suits well. Lately though, I've been seeking out DSO's with my 70mm, which is hard at that aperture. What I might do is buy a focal reducer as well and use that with the 9.25. Depending on how well it works visually, I may have to tinker with it to get it to work, but I'm not too concerned if I can't. There are larger eyepieces that you can buy that'll give low power. I've seen up to 70mm eyepieces listed. How great they might be... that's another story. I'll just have to find out.

@edting 11 ай бұрын

Don't get the 9.25 Evo. The NexStar mount is optimized for the C6. By the time you put a 9.25 on it the thing will wobble and shake too much. With a C9.25 you need a CGEM/Atlas/EQ-6. Either do that, or downsize to the Evo 6.

Hi Ed. I really enjoyed your review. One thing I would like to know is how the 9.25" planetary/moon images compares to the 8". I have a 30+ year old Meade 8" LX3 that I need to upgrade. I've thought about the 9.25" but are the views noticeably better?

@k.h.1587 9 күн бұрын

I would say considerably better, the 9.25s longer primary design makes it exceptionally sharp on planets, the extra aperture helps, as well as the starbright XLT coatings are significantly better than LX3 era meade coatings. Also meade wasn't quite into their stride as far as optics went back then, so unless yours happens to be an exceptional cherry, any c9.25 would surely be a noticeable improvement, unless your seeing conditions don't allow for larger than an 8" scope.

The 9.25" is a fine scope but at almost same size and weight overall, I prefer the C-11. I would really like to see you do a review of that 4" Unitron you have! The classic long FL refractors in the 3-4" range are wonderful instruments. I think the 3" Equatorial Unitron is the most beautiful telescope ever made. I know, I know - only 3" (actually 2.95") aperture, but what it shows, it shows very well for a discerning eye when used at practical magnifications that allow the telescope to realize its full resolution capability and maximum contrast and clarity (i.e., the 20-30X per inch range - not the empty 75-100X per inch nonsense often mentioned for aprochromats)...

9:45 I have a question Ed. Is that 2" visual back upgrade worth it even for the smaller ones like the 8" and 6" models? I have a pretty robust 1 1/4" eyepiece collection and i definitely want to invest in 2" eyepieces once I get up to some bigger scopes, but would it be worth it to invest a little now and get a few 2" eyepieces to use with my 8" SCT?

@edting Жыл бұрын

I *always* upgrade to a 2" visual back on an SCT if it hasn't already been done. Even if you don't use 2" eyepieces, the 2" back is far more secure mechanically. I like the TeleVue and the AP but any of them will do.

I’m willing to go up to $1000 an was wondering if you think going with a 10 in reflector instead of the 8 in is worth it? The weight an bulk doesn’t matter either .

I bought an Edge 9.25 about a year ago and put it on a Paramount MYT. Before that I had a C8 that I sold. I am quite happy with the photos I get from the 9.25 Edge compared to the C8. The C8 I bought from a dealer came with a spot of what I think was tar on the primary mirror. I bought the Edge 9.25 through Company Seven because I was concerned with some of the talk of Celestron quality slipping. Company Seven will inspect the telescope and if it doesn’t meet their standard they will send it back to Celestron or any other manufacturer until they get a good one and then send it to you. For the price I was putting out it was very comforting to have an independent company verify the quality. But for me the Edge is worth it for the pictures I get. Of course for visual viewing that may not hold true for some.
