Hello, Dr. Rajiv Batia is planning to be at Yerkes Observatory on Mon/Tues Jan. 26/27 to test a telescope wavefront sensor using one (or both) of the Yerkes Telescopes. If there is interest in any APO members attending that would be good because this demonstration will show if there is good application to rapidly aligning the APO/Sloan telescopes. Please contact me if there is further interest, or if you wish to see the web site for the device.
