Description
Specifications
The Lodestar X2 is an upgraded version of the very popular Lodestar autoguider. The original Lodestar uses the ICX429 Exview chip from Sony and offers excellent sensitivity. However, Sony have now upgraded the ICX429 to the ICX829, with considerably improved QE and read noise. This new 'Exview 2' chip approximately doubles the Lodestar sensitivity and adds nearly a full star magnitude to the minimum guide star brightness. We have also redesigned the boards so that a standard RJ12 guide socket can be used. This will please many users who have found the small 'ZH' cable socket to be too delicate.
1.25" diameter allows it to drop neatly into your 1.25" eyepiece holder - no additional adapters required.
Large imaging area (6.45mm x 4.75mm) gives you a wide field of view to find a suitable guide star.
Sensitivity - with an impressive 77% QE, and large pixels, the Lodestar X2 just sucks up those photons. Sensitivity is key, but combined with the incredibly low noise of the Lodestar X2, finding a guide star has just become even easier.
Full size RJ12 Autoguider Port - No need to run extra cables from your computer to control your mount corrections.
Powered by the USB of your computer so there's no need to carry an extra power supply with you - one less thing to forget when you are on your way to the Star Party.
