Starlight Xpress Active Optics unit for sale - I have owned this unit from new and it has seen very little use. When it was in use made imaging a pleasure especially finding guidestars as you are using the main telescope for you guiding (lots to chose from

) Using Maxim DL for PC control is very easy and highly recommended.
The power supply has an Australian standard plug on it and can also be connected to a 12V supply if needed (via included cable)
Specs for this unit as follows:
- STAR2000 guiding compatible.
- May be used to image stabilize many other makes and types of camera, given suitable control software.
- Clear aperture of 37mm for up to APS size chips.
- Short optical length - 64mm with OAG, 38mm without.
- Very low light loss (~2%) from the multicoated optics.
- Filter recess for adding narrow band. IR blocking or pollution rejection filters without affecting the guide camera sensitivity.
- Serial RS232 control via the computer or SXV splitter box. Parallel control available. (Splitter box and parallel control box need to be purchased separately)
- Low power consumption. Less than 600 mA at 12v DC when moving - 50mA quiescent current.
- Compact and lightweight - only 112mm in diameter x 32mm long - less than 500 grams load on the telescope.
Asking $1300 for this great piece of kit.

Grahame.
