Ioptron CEM40EC Mount Full Review

Fantastic Review man! An Ioptron CEM26 is On my possible List!

Hey Dave. Great review. Sounds like and amazing mount. I've heard alot of good things about these mounts. If only I had the $$$ 🤣🤣.

Great overview Dave, that's one legit mount! Someday...

Great review, can’t wait to see more images with this setup!

Having now set up the mount and all my equipment in a dry run, I’m going to agree with your cons and some possible solutions. 1- I almost immediately lost the 2mm screw that holds the knob for vertical adjustments. It was probably not screwed in deep enough. I also find it a bit small for the amount of torque that it has to deal with. 2- I have the same feeling about the counterweight possibly slipping. Being in the electric motor business, I’m very familiar with shafts and attaching things to them. It is common to have a flat milled on a shaft whenever a set screw makes contact for a better grip. Since I deal with a machine shop regularly, I’m having them tap one of the blanks in the knob for a larger screw, probably 4mm. I’m also having them mill a flat along the length of the counterweight shaft between the two threaded ends. Contact a local machine shop. The cost of the tapping is minimal. Many are up to doing this themselves. As far as the milling is concerned, be prepared to spend a couple of hundred bucks. It’s a long section and will probably eat an entire cutting insert and take up 45 minutes to an hour of milling time. Again, it’s not a big problem and might not be necessary but I will feel more at ease.

Great video :) ! Do you need to use the CEM40ec hand control to activate the encoders with ASIAIR connected ? Or you don’t need to use the hand control. About the extra side counter weight you use to get good balance , you just need to adjust the counter weight bar to get this problem resolve

Thanks for this. Currently have a GEM28 which I love but guiding....grrrrr...realize I may need to do some with an EC version but not as much fiddling with the guiding on the AIR attached to it. Spending the next few weeks comparing this to the RST-135E and the new Pegasus Astro as well

Thanks a lot for the review!
Just a brief question..... Do you have to set the Home Position on every imaging session? Or is is enough to set it once, move to Home at the end of the session that it will remember the Home Position next time?

What exposures times can you get un-autoguiding with 250mm, 800mm telescopes? Great video!

Gorgeous 😍

Great video! Question for you, for some reason I thought only the RA motor had an encoder on it and not on the Dec motor. Do you know if that is true? I have had an absolute nightmare with mine and trying to makeup my mind on what I want to do moving forward. Thanks much!!
