Info on every type of mount possible..

Crude astro photography mount performance overview.

Facinating comparison, I have had 25kg+ on my EQ6 with no trouble and think the EQ6 is outstanding at a give away price a couple of years ago allowing many more astronomers into LX imaging. Enhanced in a major way with inexpensive EQmod.

A Winner!!!

Hi Doc, glad you like my list I hope it's useful for astrophotographers who are looking for a new mount.

If anyone has additions or suggestions then please let me know. There must be other commercially available mounts out there that i'm not yet aware of.

It is indeed a great resource and I hope you don't mind me sharing it with this group.

I think the CGEM figures for PEC are a bit off, I reckon that guy had something set badly wrong with his image scale when he did the testing. You can see my results with graphs for both uncorrected and corrected here :

Great resource though, very useful for anyone researching a new mount!

Hi Tim,

I found it high too, but it was the only PE data i could find on the CGEM.

That looks a lot better, and more in line with my expectations of the mount. Thanks, I've added your data to the list.

Thanks, I hope it's useful.
