SJAA

Ephemeris

Y2K strikes the SJAA!


Paul Barton reports that the club's eleven inch Compustar has a Y2K problem.

On Paul's eight-inch Compustar (and others like it), dates are assumed to be in the 1900's. The operator only enters the year - 80's and 90's only - but the year 00 cannot be entered.

Several years ago, Jim Van Nuland suggested going back 4 years might work, and it does! The years 1995 through 1999 all work okay; the scope will polar align and go to designated objects reasonably accurately.

Although this scope is a bit cranky, Paul says, it was truly an eye popping demonstration when it was introduced 20 years ago by Kevin Medlock.
