You can rely on PlaneWave Instruments’ professional CPWI software if you want to control your Celestron telescope via a laptop or PC.
This software is not only intuitive to use, but also lets you maximise the GoTo accuracy of your Celestron mount.
CPWI Telescope Control software is now compatible with all modern Celestron mounts, including:
You can download the software for free here on celestron.com!
PlaneWave Instruments Telescope Control panel
Some special features of CPWI software include:
- The built-in SkyViewer star chart is intuitive to use and allows you to easily navigate through the night sky by clicking and zooming.
- Advanced PointXP lets you create a highly accurate model of the night sky which uses more than 100 reference points to enable highly accurate positioning and tracking.
- Ideal for observatories: You can carry out alignment directly from the PC, save the alignment model and simply upload it again the next night you observe. Alignment can also be done entirely automatically using the optional StarSense module.
- Extensive internal database. Access to the SIMBAD professional astronomy database possible via the Internet.
- Worm screw periodic error compensation: PEC can be done from the PC via CPWI.
System requirements: Windows 7, 8 or 10 operating system, with USB 2.0 or 3.0 connection, 15MB hard disk space and 64MB RAM. Screen resolution of 1024×768 or higher is recommended.

CEM series mounts from iOptron are already widely used in the US and are becoming increasingly well known in Europe too. The CEM25P mount for portable astrophotography with Newtonian telescopes of up to 6 inches aperture and the CEM60 mount for use in observatories have proved particularly popular.
With their new CEM40 and CEM40-EC with encoders, iOptron now provides a middle range mount capable of carrying loads of up to 18 kilograms. The CEM40 is hence ideally suited for astrophotography with telescopes of up to 8 inches (200 millimetres) in aperture.
The CEM40 is the latest addition to iOptron’s CEM series
The abbreviation CEM stands for centre-balance equatorial mount, i.e. for equatorial mounts which are supported at their centre of gravity. This design ensures an excellent relation between weight and carrying capacity. The CEM40 weighs only 7 kilograms and yet can carry OTAs up to 2.5 times heavier. The amazing carrying capacity of CEM mounts has been constantly reaffirmed by our customers – especially regarding the CEM25P.
The CEM40 comes equipped with an electronic pole finder, known as ‘iPolar’. A laptop is required to operate this however, so the CEM40 is particularly suitable for astrophotographers who already use a laptop for their camera. iPolar and built-in GPS provide easy and accurate alignment and GoTo computer control initialization.
The encoders installed in the CEM40-EC version ensure very high GoTo accuracy and allow worm gear permanent periodic error correction – a problem that all mounts suffer from. The CEM40-EC does away with the need for guiding with your astrophotography.
The CEM family now covers a wide range of load carrying capacities, offering a suitable model for every budget!
