What is the main benefit of the 90-degree connector on these cables?
The 90-degree angled connector significantly reduces cable strain and creates a more compact, snag-free setup. It allows the cable to run parallel to the device it's plugged into, which is ideal for tight spaces on a telescope rig and helps prevent accidental disconnection if the cable is bumped.
Can these 5A rated cables power a cooled astronomy camera?
Yes. The 5A maximum current rating is more than sufficient for most cooled CMOS or CCD cameras, which typically draw between 2A and 4A when the cooler is at full power. These cables provide a safe margin and ensure stable power delivery.
Are these 50cm cables long enough to connect a mount to a power supply on the ground?
No, the 0.5m (1.6 feet) length is intentionally short. These cables are designed for connecting devices that are mounted close together on the telescope itself, such as linking a USB hub, focuser, or camera to a power box like a Pegasus Astro Pocket Powerbox mounted on the optical tube.
Will the 2.1mm x 5.5mm connector fit my ZWO or QHY camera?
The Male 2.1mm x 5.5mm barrel is the most common standard for 12V DC power in the astronomy industry. It is compatible with the vast majority of devices from brands like ZWO, QHY, Pegasus Astro, and others. However, you should always verify the specific power port size on your device before purchasing.
Is there a risk of voltage drop with a 50cm cable?
At this short 0.5m length, voltage drop is negligible, especially with a cable rated for 5A. The cable's heavy-gauge wiring ensures that your equipment receives a stable voltage, which is critical for the proper function of sensitive electronics like cameras and focus motors.
Why does this come as a pack of 2 cables?
Most imaging setups require multiple power connections on the telescope OTA. This two-pack allows you to cleanly wire two separate devices, such as your camera and electronic focuser, back to a central power hub. It also provides a convenient spare for your field kit.
