Wide+Field+Camera+Autoguiding

An Autoguider has been installed and tested.

The Autoguider camera is a Starlight Xpress MX716 USB1.

This is attached to an old Russian 300mm F4.5 Telephoto lens that I have had for decades.

Periodic error in the RA drive can be seen below. X axis minutes. Y axis is arc seconds.

An excellent guide to setting up the Autoguider is here: []



Once the Autoguider was guiding, this was almost significantly reduced. More tests are ongoing to tune the system.



Autoguider settings for this system are below. The Wide Field Camera is 304mm FL. The Guide scope is also 300mm FL, but has lower resolution (approx 7 arc/secs/pix) than the Wide Field Camera (3 arc/secs/pix)



During calibration, the telescope is moved in RA and DEC. The small red 'L' shaped lines on the guide star should be seen. 20 pixels or so is about right.
