M82 is an elongated galaxy in Ursa Major, often paired with M81 in observing plans. Its apparent form makes the pair useful for learning how galaxies can look different through the same instrument.
Compare shape rather than colour
Locate the M81 and M82 field with a current chart and a low-power eyepiece. Confirm which galaxy is which from their positions and shapes. Under suitable conditions M82 looks more stretched than M81, but published red outflow structures are not a reasonable expectation for a quick small-telescope view.
Use astronomical darkness, limited moonlight and a target altitude clear of your local skyline. Its far-northern position restricts access from southern latitudes, so check geometry before spending time on a weather score.
Record the length, orientation and any secure brightness variation you notice. Increase power cautiously and compare with the wider field. If the target is ambiguous, keep the identification uncertain and try again under a darker sky with the same finder chart.
Check it from your location
A target's altitude and direction change with your location and time. Use a city session to see sampled positions. Deep-sky objects also need enough darkness and suitable optics; being above the horizon does not mean they will be visible.
