Great pointers Dave, that will be easy to find. Perseus is not that hard to see. It is one of the circumpolar constellations, so is pretty much always in the sky, northern hemisphere of course.
Has anyone observed a blink of Algol? That is one of those things that I have always wanted to see, but have just never planned a time for it.
For those not familiar with it, Algol is an eclipsing binary star system, One of the pair of stars is much dimmer. Every 3 days (approximately) the dimmer star passes in front causing the star to appear noticeably dimmer for short period. The ancient Greeks observed this change in brightness and saw it as the blinking eye in the decapitated of head Medusa.
