Review: Nice telescope - Nice telescope, pretty compact, I'm no telescope expert but it does the trick for me for both celestial and terrestrial viewing.
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.

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

### ⭐⭐⭐⭐⭐ A Bargain
*by Y***R on January 10, 2026*

With all the talk about the Edge HD's, these SCT's get less noticed. However, they are a bargain and the performance is excellent. Bright images with the same Starbright coating as the HD's. Add the Celestron 6.3 reducer for reasonably fast exposure times. I also added the dew ring and aluminum dew shield. Both work great. Portability of this 6 inch is great. I haven't had to deal with mirror shift either. GSO makes a great refractory type focuser with 10/1 fine tune which eliminates mirror shift. One would have to spend MUCH more for this type of focal length from a refractor.
