Quote:These results shouldn't be a surprise. The well regarded CGE mounts and Nexstar GPS scopes shared virtually the same motors and gears, the bearings however were different due to the very different mount types (gem vs. Alt Az/wedge). CPCs have only changed a little bit from the Nexstar GPS scopes, they still have the same size worm/spur gears and motors.Nice to see someone take the time to get some numbers on the CPCs.
Quote:Thanks for clearing up the data.I've added your results to my list of astrophotography capable mounts at http://lambermont.dyndns.org/astro/pe.html you're the 75th entry -- Hans
Quote:Do you want the payload rating of just the scopes+equipment or the whole shebang with fork arms and everything?
Quote:Just the payload (OTA+equipment) so it can be compared to the other mounts. This is a little hard as your OTA is integrated ;-) and Celestron does not clearly specify its mass nor the maximum attachment/piggy-back load AFAIK.So I'm fine with an educated guess here ;-) I had to do the same for Meade's LX200.
Quote:Psyire,That looks really good. With PEC runningand at shorter focal lengths and exposures you could probably get away with not guiding at all.Patrick
Quote: The CPC mounts seem to be able to hold anything the CGE except there is no 14" SCT version.
Quote:I wouldn't go quite that far. The fork mounting puts a lot of stress on the azimuth bearing since there is no counterweight. There is no way I'd want to put 60+lbs of instrument payload on a CPC or NS GPS fork mount. This is especially true at lower lattitudes ... the lower the less the mount will be able to carry, the higher the more the mount acts like an Alt Az and the less stress on that Azimuth bearing there is.I think 20kgs/44lbs is probably a safer number that would cover a wider range of setups on a fork mounted CPC or Nexstar GPS scope.
