Starlight Xpress
Starlight Xpress Lodestar PRO Autoguider (Colour)
$899.00
The Lodestar utilises a very sensitive Sony ‘ExView’ CCD (the ICX829AK) with an array of 752 x 580 pixels in a ‘half-inch’ format. Although the chip is not cooled, it has a very low dark signal and very little readout noise, so it can be used to guide on faint stars that are beyond the reach of webcams and CMOS chip based guide cameras.
Specification
-
