all the Messier’s in one night?

[Marvin Jenkins]

Is it possible to observe the whole 110 Messier’s in one perfect clear night? I am at 44 deg lat and frustratingly at 109 of 110 Messier’s with M68 left.

From my understanding I have to wait till Feb weather permitting to say 110. Is there a point in the year when all M’s are visible at the same time?

Hello Marvin,

maybe this can help: Messier Marathon Planner. There's also an excellent book Observing Guide Messier Marathon on this subject.

Kind regards,

Yes, as AstroRookie says the challenge to see them all in one night is called a Messier Marathon. They're not all visible at the same time, but every Messier object can be observed through the night if your latitude is not too northerly (because of the shorter twilight duration). This is possible in a few weeks in March and April.

A 'half marathon', when most objects but not all can be observed, can be held around the September equinox.
