## Questions & Answers

**Q: How will the edge hd 1100 work with a celestron cgem? please help.**
A: That would be pushing the mount to its limit for visual use.  It wouln't work well for photography, and if you add the weight of a guide scope, it won't work at all.  The Sky-Watcher EQ6 has more headroom in that rated 40 pound capacity than the CGEM does.  If you want to stay pure Celestron, look foe either a CGX mount or one of the recently discontinued CGEM DX or CGE Pro mounts.  There are still plenty of the latter to be had at deep discount.

**Q: Can this telescope be used on any dovetail mount?**
A: No, this is a vixen style dovetail (1.75” wide). If your mount uses CGE (3” wide), then you will need to get an adapter either from your tripod/mount manufacturer or a third party company like ADM.

**Q: What is the diameter of the ota itself (not the mirror)?   this is needed to properly size an electroluminescent flat panel.**
A: I have a 8 " EDGE HD scope but both of my 11" SCTS are not EDGE HD. They are older models and with carbon fiber tubes so while I can measure those it MAY be different than mine. Let me know how critical the measurement needs to be.

**Q: Will this work with a sky-watcher eq6-r – fully computerized goto german equatorial telescope mount?**
A: The sky-watcher eq6-r has a dual vixen-losmandy saddle.  The mounting plate on the C11 EHD is a CGE.   Either need to find an interface adapter or replace the plate.  Also, the C11EHD weighs 28lbs, bare bones.  The mount is rated for 44lbs.  Might want to get a slightly beefier mount if you're going to do astrophotography.
