M81 is a spiral galaxy in Ursa Major. Its brighter centre makes it a useful galaxy target, and nearby M82 offers a contrast in apparent shape within a suitably wide field.
Plan for the northern sky
Check the altitude for your latitude. A northern target can be well placed for one observer and below the horizon for another. Use a detailed chart to reach the field, then confirm the orientation and separation of the two galaxies rather than assigning the first fuzzy patch a name.
Choose the Faint objects goal and avoid direct glare. A low-power field helps preserve context; more magnification is useful only if the image remains bright and steady enough. Spiral detail should not be assumed from an introductory view.
Record each galaxy separately in a sketch, including which appeared more elongated or centrally concentrated. Make the comparison with the same eyepiece and conditions. The visual difference can be rewarding even when neither looks like a processed observatory photograph.
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.
