No one seems to have noticed, but next December 25 marks the 250th anniversary of Palizsch's recovery of comet Halley, the first time a comet was predicted to return

I have a feeling that the Wikipedia reference is for the first eyeball-to-eyepiece *visual* (not photographic) recovery of Halley prior to its 1986 perihelion, and that Mike is referring to the first *photographic* recovery of the comet.

Mike is referring to the first *photographic* recovery of the comet. Technically, Ed Danielson was using the PFUEI (Prime Focus Universal Extragalactic Instrument), which was a cooled CCD camera based on the TI 800x800 sensor used in the first WF/PC on HST. Ed went on to be the instrument manager on the Mars Observer Camera. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
