Was easy to install on the mount of my 8" Dob and now the azimuth is so much smoother. Not a lot of money for a big improvement. Took the frustration out of slewing. Highly recommend for anyone seeking to improve az motion. I'm in love with my scope again!

Comes with a sturdy case and is ideal for a very wide range of DSOs. Even the ones it can't fit in frame look stunning zoomed in on.

I have now used it several times in conditions where my books by table, my gear cases were covered with dew but my eyepieces telrad and Finder scope were all dew free at 3 am when I called it a night

Works great on my 12.5" Classic Obsession with ServoCAT. Great images - and with the hand controller usable with an eyepiece as well.

The usual great quality product from Apertura. This cable is perfect for connecting my BLUETTI battery (5521 connector) to my iOptron mount (5525) without need of any adapters.

The Atik 414EX monochrome is a great little camera. We use it in imaging systems and the photos it takes are very crisp and clear.
