iOptron iPolar Electronic Polar Scope for CEM25: electronic polar scope
With the iPolar, you align an iOptron CEM25 to the celestial pole via your laptop screen. The built-in camera shows the actual polar position and the direction of the polar axis; using the azimuth and altitude screws, you bring both points together.
The software automatically calculates the exact pole position based on date and time. Looking through a small optical pole finder is no longer necessary, and alignment is also successful even if Polaris is not clearly visible.



Accurate at every location
The sensitive sensor with a wide field of view finds the correct orientation even after a rough alignment. The iPolar works in both the northern and southern hemispheres and remains usable at low latitudes. Precise polar alignment extends the usable exposure time without guiding.
The connection to the computer is via USB 2.0.

Assembly
This version is made for the CEM25 and replaces the optical polar scope in the polar axis. Mounting hardware is included; for the CEM25P, the separate iPolar adapter is available.
Included
- iPolar electronic polar finder

Featured accessories
Keep a USB cable as a spare in your luggage, then a forgotten cable will never get in the way of a session.
For whom yes and for whom no
- ✓ iOptron CEM25 owners who want faster and more accurate polar alignment
- ✓ Astrophotographers who want longer unguided exposures
- ✗ Who perceives exclusively visually: then the optical polar finder is sufficient
