Quote:Hello,I'm looking for a fairly inexpensive computerized GEM. Right now you can get some pretty good deals on the Sky-Watcher EQ5 PRO. I've considered the CG-5A but all of the discussions on how noisy it is has me worried. The EQ5 Pro seems like a possible alternative but I've heard that it's actually manufactured in the same plant with the CG-5A and they are very similar mounts. Is it as noisy? Aside from noise issues how does the EQ5 Pro compare to the CG-5A?Thanks, Ken

Quote:Now that re-read the OP's post I am certain he really is discussing the EQ5 PRO and not the HEQ5 PRO. So if he doesn't like the noise level of the CG5 then he won't like the EQ5 Pro either. Since everything I found says these are the same mount just given different names for different markets.

Quote:Part of it is the motors, part of it is how they are mounted. My SVP with these motors was fairly quiet in RA but noisy in Dec, with the Dec motor being mounted directly to the saddle, allowing vibration to radiate into the OTA with not a lot of damping before it gets there. The non-H EQ5 will also have this issue.Another thing, the CG-5 trick of slewing manually at a slower speed to get quieter operation doesn't really work for these stepper motors, they are very close to the same loudness at any of the slewing speeds from 6-10 I found. And of course the loudness lasts longer at speeds less than 10.My opinion is the OP should not consider anything other than HEQ*/Atlas/Sirius if they are concerned about noise.Mike
Quote:I didn't say my SVP was as loud as a CG-5, all I'm saying as the Dec motor noise was likely louder than it would be on one of the newer-design mounts where the Dec motor is tucked deeper within. Personally, it exceeded my tolerance, whereas the RA motor noise I could live with.
