Review: Five Stars - I read all the review before I made my purchase the celestron 91010XLTC6. The image is super.with great accuracy.Nice telescope.
Review: Al lot of image shift and back lash in focuser knob - Dislike the focuser image shift and to much back lash in focuser knob. Like. The image is bright and sharp after the telescope cools down but can take a long time if different than outside air temp. Pricy for a plastic end cap scope. Needs a standard dove tail for a different finder scope. Replaced the factory one and use a SvBony straight through correct image illuminated finder scope. Used ZWO ASI678MC camera and and a 2X barlow, the ZWO app software for stacking and post processing for this image of Saturn and moon craters.

## Questions & Answers

**Q: I don't like EQ's or GOTO's.  Is there a manual ALT-AZ mount that has slow-motion control cables that is compatible with this telescope?**
A: Rene,  this OTA comes with a Standard Celestron Dovetail mounting strip, which should be compatible with most all Celestron (and probably many other) ALT-AZ mounts with a dovetail slot.  As always, the trick is to get a good mount and tripod.  Check out the Celestron Omni CG-4 Mount Equatorial Telescope Mount (on EBay and elsewhere).  I have one of these for a good manual telescope tripod/mount.  It's about $300, give or take, but worth the money.  Clear skies!

**Q: How much does it weigh?**
A: Advertised weight(from Celestron) is 10lbs, but the actual weight is a touch over 8lbs with included accessories.

**Q: Can this be used for Astrophotography ?**
A: Certainly. You can attach various accessories to it for that purpose. Check out Cloudy Nights or other websites for advice.

**Q: Will this fit on the EQM-35 mount and tripod?**
A: If you are using this scope for visual use, that mount will be ok. For Astrophotography a more robust mount would be a a better fit.

### ⭐⭐⭐⭐⭐ Five Stars
*by M***L on November 7, 2016*

I read all the review before I made my purchase the celestron 91010XLTC6. The image is super.with great accuracy.Nice telescope.

### ⭐⭐⭐⭐ Al lot of image shift and back lash in focuser knob
*by A***R on August 20, 2024*

Dislike the focuser image shift and to much back lash in focuser knob. Like. The image is bright and sharp after the telescope cools down but can take a long time if different than outside air temp. Pricy for a plastic end cap scope. Needs a standard dove tail for a different finder scope. Replaced the factory one and use a SvBony straight through correct image illuminated finder scope. Used ZWO ASI678MC camera and and a 2X barlow, the ZWO app software for stacking and post processing for this image of Saturn and moon craters.

### ⭐⭐⭐⭐⭐ It's big, bright, clear, heavy, and f/10
*by R***T on July 15, 2015*

This thing is huge. Be sure you want an F/10 scope though, while It's great for planetary viewing there are scope types better suited for viewing DSOs (nebulas etc).. The high gain makes bright objects like the moon VERY bright. The focus works better than I expected with no slop and a nice greasy feel with no grit or stiction. The finder is the usual straight through crap that requires a limbo artist to use when pointed anywhere but your neighbors window. I have never noticed any mirror flop when panning around wither, needing very little refocusing not caused by varying human eyeballs.
