I have a deforked ETX 125 from about 2002, it sat in the original box for about 12 years and has been redeployed! I recently bought a CEM25P and some eyepieces. Having a great time with it but feel like I want something that will take me a bit deeper. I only do visual and will likely mostly just do visual for the foreseeable future. I would also like to use my existing eyepieces and maybe add a few.

 

So as the title suggests, I am considering an 8" or 9.25. I have no experience at all with refractors and so haven't been considering them. My viewing conditions are edge of town, Santa Fe. There is some light pollution but otherwise, cold clear nights at high altitude. So far I have had nice views of Orion Nebula. I could even faintly see M110 while viewing Andromeda and so would be excited about deepening the experience.

 

All opinions are welcome other than buying a different mount hence the 9.25 is probably the weight limit.

 

thanks!

I've owned both in the past. The C8 was nice and gave nice views and if one wanted a grab and go scope for casual observing when time permitted, would be hard pressed to find a better scope than a C8 for that. But the C9.25 had a "wow" factor that the C8 just did not. Planets through the C9.25 were amazing. Through the C8, they were very nice. However, the C8 I had was an Orange tube with Special coatings and not a newer model with XLT so that definitely might have been a contributing factor in my perception of the C9.25 having a much bigger "wow" factor than the C8. The C9.25 was newer with XLT coatings. Others may have different experiences with both scopes.

Having viewed through both, if I were able to choose between the two of them right now it'd be the 9.25 hands down every time.

Ditto for me, except for its 22 lb weight.  If that is not an issue for you, then go for the 9.25.  What mount would you be upgrading to to use this OTA?

Agreed - having had a number of C8s and now being on my second C9, I would also go for the C9. But as stated above:

 

  if portability is king or if 22 lbs is too much to handle or if getting a C9 means getting a different mount... consider a C8.

 

Clear skies and good luck!

I have a Meade 8” SCT and a Celestron 9.25 SCT, and use them both.  Sharpness is similar, but the 9.25 goes deeper and may show more detail on solar system objects if the skies permit.  However, the weights (and mount requirements) are significantly different.  If I could have only one, I’d probably keep the 8” for its ease of use.

I have both and I like both. The smaller package of the C8 is much more convenient, but the C9.25 gives better views. If I were forced to choose between them (at gunpoint), I'd choose the C9.25 without hesitation. Sure, I'd be sad to see the C8 go, but the consolation prize is the view through the C9.25. That'll lift my spirits any time (as long as the seeing cooperates).

Thanks for all the replies. Sounds like the 9.25 . Ill keep the 125 for grab and go. I

 plan on using my cem25p . With no accessories I assume it will handle the weight

I have thought of this many times should I get rid of my nice C-8 for the heaver larger C-9.25 or should I just go ahead and get a Meade 10 sct are the view just that much better probably.  What is the size and weight diffract between the Meade 10 sct and the C-9.25 ota and would my Meade LXD-75 mount carry either of these scopes for visual use or would I have to buy a new larger heaver mount to handle these scopes. As you can see there is a WOW factor with the increase in scope size not only in viewing quality, but and for me the WOW factor is also the cost increase per inch of aperture.

 

 

C-11 XLT ota                                    $2300  27.5 pounds

Meade 10 AFC ota                           $1700  28 pounds

C-9.25 ota                                         $1379  20 pounds

My C-8 XLT bought used $400 new $999  13 pounds

I used to run a 10" Meade SCT on an LX-75 mount - I just had the dove tail, the OTA, a finder, Telrad, and 2" diagonal - the whole lot weighed in around 25lbs, which was around the upper limit of the mount. As long as I had the balance set up right (for both axis) it ran fine.

Yea I have two weights I would need to get another but its good to know the Meade LXD-75 would handle the weight.

I once owned both a C9.25 and a 10” Meade ACF and had them out side by side a few times to compare the views.  There was no visible difference seen when looking at the same objects (galaxies, globulars, planets) given the only 3/4” of aperture difference.  Both scopes put up very nice views.  The main difference was the weight with the Meade weighing some 8 pounds more.  Given you have a C8, I would opt for the C11 as it weighs the same as the 10” Meade.

FWIW telescopes .net has a massive Celestron OTA sale right now. $700 off a C11 XLT.  Only Edge on sale is 8", thinking about picking that up.
