-1 EM200

Used NJPs come very close to the price of used EM200's and frankly a new EM200 is a bad deal at close to the price of a Mach1, no GoTo from the handset, and no PEC.

The NJP doesn't really need PEC due to the sub-5" (often sub-3") periodic error. But the EM200 is only guaranteed to +- 7" I believe (so 15" p-p).

Out of curiosity, what is involved in hyper tuning a mount?

Seems like I'm leaning toward the Atlas mount based on comments here and other things I've seen online. So much to think about, particularly as it pertains to the guiding system.

Yes there is room for upgrading the EQ6, especially with the tripod. I added a TPI spreader and battery tray to mine and it made the setup rock solid.

I could have saved a lot of cash if I had followed the above advice.

There is a bit of upgrading you can do to an EQ6 - buy an Aeroquest worm for it, or if you are feeling flush, buy a matched Aeroquest worm and ring gear for the RA. Still under $500 additional.

You don't necessarily have to hypertune the EQ6. My first one needed it, my second one was excellent out of the box. However, I did adjust the gears twice a year for the temp extremes. I did the same with my Mach 1 this winter, the procedure is quite simple and speedy with that mount. I'm sure many owners of the EQ6 don't make any adjustments at all and are quite happy with it.

Hi,
Go with the EQ-6, Their pretty good right out of the box. Unless you want to spend big bucks then get the Mach-1.

I had some similar issues with my CG-5 couple years back. You can pretty much do it yourself if your inclined. Here's a link to a hypertuning site.

Basically, they rebuild your mount head bearings and replace grease, etc. If your so inclined you can do it yourself. On my old CG-5 I did it myself. What really helped was getting rid of all the sticky grease and replace with high grade synthetic grease. I also removed any metal burrs and cleaned up the gears/bearings. The big thing is the configuring of the worm gear meshing and backlash adjustments in RA and DEC. Once I did this, the mount tracked much better than when it was new.
