Hi,  I am in market for an upgrade mount,

I currently have a Skywatcher AZ/EQ6 and using a Skywatcher Esprit 150 on it.

I have been doing quiet a bit of research and i think i have come down to the iOPtron CEM120 mounts as a good choice.

I think i am deciding between the CEM120EC and the CEM120EC2

This might be an odd question, but if i am in the position to go with either one,  would it be the wiser decision to go for the CEM120EC2 version?

I am planning to mount it on a iOptron Tri-Pier 360 as i do not have a permanent setup 

 

I realize these units do weight in heavy,  but i think mounting the unit to the tripod should be fine.

I see there is also a lot of mixed ideas and advice on weather you can run PHD2 with these mounts.

 

Any advise would be appreciated.

Thanks.

I think for EC you should guide which makes it useless. EC2 may work without guiding. 

The guiding problem with PHD2 was solved for CEM60EC long time ago. I am not sure if it is solved for CEM120 as well.

 

Thanks,

Mo

I had CEM60EC and it was excellent. I have CEM70 now and it works well. I am using it with an EdgeHD 11". I guess the weight is higher and the length (after adding reducer and OAG) is close to a 150 mm apo. The guiding result is very good (0.4" to 0.7" based on seeing).
