Webcam kits for imaging or polar alignment

Post by rwilkinson » Wed Feb 16, 2011 8:43 am

We have two of these webcam astro-imaging kits:

which comprise a modified Philips SPC880 webcam, along with a special bracket and one or more camera lenses.
The webcam can be fitted to a telescope and used in Normal mode for lunar and planetary imaging, or with a camera lens in Long-exposure (LX) mode for deep-sky imaging.
The lens-mounting bracket is threaded to mount onto the "piggy-back camera" thread of many 'scopes, but note that you'll need to provide your own motorised equatorial mount to track the sky, and of course a PC (or laptop) to run the webcam and associated image-processing software (all free downloads).
For Normal mode a USB connection is used, but for LX mode an additional COM port (maybe via a USB-to-serial converter) is required.

Compact pole-camera

Post by rwilkinson » Thu May 11, 2017 8:58 am

I've converted one of these webcams into a pole-camera for use with the Polar Alignment tool in SharpCap.

The camera now runs from a single USB port and is fitted with a compact 50mm lens.
It has a standard 1/4" tripod bush on the bottom, so it can fit on any bracket used for a DSLR camera.

It also comes with a clamp for attaching to the balance-arm of a "German" EQ mount.
