The new guidescope setup is working well. It is guiding at about one second of arc rms error. The PL16803 imaging camera is 3.1 sec of arc per pixel.
With the guidescope firmly bolted to the camera frame it is the equivalent of off axis guiding without any of the drawbacks such as filter attenuation and distorted guide stars. Even though the flexure is minimal with the OTS frame it is still there for long exposures.
The last image is a screen capture from my computer monitor inside the house away from the mozzies of the laptop controlling everything in the observatory. With Logmein I have full control remotely of my system. This image also shows the tracking errors of the mount.
