Having the same compact mechanical dimensions as the MX5, it is a miniature cooled
camera, with ideal characteristics for the smaller telescope, or telephoto lens. It exhibits by
far the best price/ performance ratio to be found in CCD cameras costing up to at least £1500,
and gives you 660 x 494 pixel images from a (larger than average) 4.9 x 3.6mm chip. In
addition to this excellent CCD specification the camera also provides a 16 bit data output as
standard!

The system consists of a 50 x 100mm cylindrical camera head, weighing only 200 grams (7
oz), a 5 metre lightweight cable, and a small power module for mains, or battery use. A 'Port
Accelerator' module is also supplied as standard, to optimise the download speed, although
this is not essential.

The camera head is complete with a 1.25" drawtube adaptor and has a M42 Pentax thread
barrel to allow you to screw on various standard camera lenses. A tripod bracket is also
supplied. To operate the HX516, you will need a PC computer with a standard 25 pin printer
port socket. The computer must be running Windows 3.1, or higher, and should be at least a
66MHz 486DX2 for best results.

The HX516 comes complete with a versatile Windows based control and processing program,
Pix_H5, which gives you an extensive range of features, without the need to buy additional
software. Further technical details of the HX516 are given below.

The HX516 camera specification:

Sony ICX084AL HyperHAD CCD with ultra low dark current and vertical anti-blooming.
Pixel size: 7.4 x 7.4uM, Image format: 660 x 494 pixels (unbinned).
In 2 x 2 binned mode - Pixel size: 14.8 x 14.8uM, Image format: 330 x 247 pixels.
Imaging area: 4.9mm (horizontal) x 3.6mm (vertical).
Spectral response: Peak response at 520nM (Green), 50% at 400nM (Violet) and 670nM
(Near infra-red). (Note the very good blue light performance, excellent for Tri-colour work.)
Readout noise: Approx. 15 electrons RMS.
Full-well capacity: Approx. 40,000 e- (160,000 binned).
Anti-blooming: Overload margin greater than 800x
Dark current: Dark frame saturation time greater than 5 hours.
Data format: Full 16 bits.
Computer interface: 8 bit unidirectional parallel port with bi-directional status lines (Standard
Centronics interface). 25 pin 'D' style plug for LPT1, 2 or 3, via a 5 metre x 6mm diameter
cable.
Image download time: Typically 20 seconds with a 66MHz 486 PC, when using a port
ccelerator module. Only approx. 8 seconds in 2 x 2 binned mode.
Power requirements:115VAC / 240VAC @ 12VA, or 12VDC @ 700 milliamps max.
Cooling system: Regulated constant-current cooling supply built-in. Single-stage
thermoelectric cooler to give a CCD temperature of approximately -30C below ambient.
Size: 50 x 100mm black anodised aluminium barrel with M42 thread at CCD window end and
15 way 'D' style input plug at rear.
Weight: 200g.

Price - £895.00 plus £10.00 p&p
With USB Interface - £995.00 plus £10.00 p&p
