What is the difference between this NexStar+ AZ USB hand control and the older, non-USB version?
The primary difference is the USB port. This modern version allows you to update the firmware directly with a standard USB cable connected to a PC. Older models had a serial port at the bottom that required a USB-to-RS232 serial adapter, which was often less reliable.
Can I use this NexStar+ AZ Hand Control on my Celestron Advanced VX mount?
No. The Advanced VX is a German equatorial (EQ) mount and requires the NexStar+ EQ Hand Control. This AZ version lacks the specific firmware and polar alignment routines necessary to operate an equatorial mount correctly. Using the wrong controller will lead to failed alignments and poor tracking.
My old NexStar hand control failed. Is this a direct replacement for my NexStar 8SE?
Yes, this is the correct and current factory replacement for the hand control that originally shipped with all NexStar SE series telescopes, including the 8SE. It is also the correct replacement for SLT, CPC, Evolution, Astro Fi, and LCM series telescopes.
How do I update the firmware on the NexStar+ Hand Control USB?
To update, you will need a PC and a USB-A to USB-B cable (not included). Download and install the free Celestron Firmware Manager (CFM) software from Celestron's website. Connect the hand control to your PC, run CFM, and the software will automatically detect the device and download the latest firmware.
Does the NexStar+ Hand Control work as a standalone device?
Yes, absolutely. The NexStar+ Hand Control is a self-contained computer. It plugs into your Celestron mount's "Hand Control" or "HC" port and manages all alignment, database, and GoTo functions without needing an external computer or WiFi connection.
What kind of objects are in the NexStar+ Hand Control's "Tour Mode"?
The Tour Mode generates a customized list of the best objects to view based on your current time, date, and location. It typically includes a mix of popular targets from various catalogs, such as:
- Bright nebulae like the Orion Nebula (M42)
- Galaxies like the Andromeda Galaxy (M31)
- Globular clusters like the Hercules Cluster (M13)
- Open clusters like the Pleiades (M45)
- Bright double stars
