Description Technical Specs Support Documents

You can now upgrade your ZEQ25 mount, which uses servo motors, to the CEM25 stepper motor package. We have developed technology to deliver all of the benefits of stepper motors (reliability, accuracy, quietness) without the high power consumption associated with steppers.

The 2 options are listed below; the difference is that option 1 includes replacement worm gears, option 2 you use your current worms. (The old and new worms are of the same specs.) Purchase option 1 if you desire a ‘fresh start” on both sides of the gearing.

Option 1 Upgrade to stepper motors, using replacement worm gears.
Upgrade kit cost is $610 (final cost is $400 after $210 refund when all the old parts, in working condition, returned to iOptron).

Option 2 Upgrade to stepper motors, using your current worm gears.

Upgrade kit cost is $470 (final cost is $300 after $170 refund when all the old parts, in working condition, returned to iOptron).

We recommend sending the mount in for upgrade unless you are good at DIY and following the procedure precisely. It might cause worm damage if encountered gear slip during the upgrade. The labor cost is $100 for Option 2 (with original worms) and $50 for Option 1 (with new worms.)

Customer is responsible for all other cost.

This offer may be changed/stopped by iOptron at any time. For more information, please contact iOptron customer service at support@ioptron.com.

ZEQ25 to CEM25 Upgrade (Option #2) November 11, 2015
Reviewer: Michael Warren from Pittsburg, CA United States  
My mount went to iOptron for the upgrade the first week of October. Mine was the third ZEQ25 the tech shop had converted. Total down time was just over one week. Upon return the mount powered right up, got GPS lock (in the house) in less than two minutes, and tracked excellent. It also was rock solid in DEC and ALT. AND I COULDN'T BELIEVE HOW quiet IT WAS! My OTA is an 152mm Mak-Newt. Outfitted for DS photography, my OTA is about 17 lbs. I am still able to use my StarFi module through Sky Safari 4 Pro. Two days after receiving the mount back from iOptron it got a good workout at our clubs monthly outreach. Absolutely no problems! Optical performance and goto slews were spot on. I highly recommend this upgrade if you are looking for that extra little performance out of your mount. The crew at iOptron deserves kudos for their continued inovation.

ps - iOptron needs to release an updated manual for the CEM25 for the many changes from the ZEQ25, especially in the handbox menu structure.
