The central region takes up most of the diameter, with a faint haze surrounding it. You’ll need magnifications above 400Â and at least a 16-inch scope to identify the diaphanous spiral arms. They certainly do hug the galaxy’s core tightly. 9 290 Open cluster Our next target is the ‘‘other’’ open cluster in Cancer, M67. (It’s the one that’s not the Beehive [M44]). 3 Alpha (a) Cancri. January 45 Through a 4-inch telescope, you’ll resolve roughly two dozen stars in M67 across an area two-thirds the width of the Full Moon.

Around that date, it sits opposite the Sun as seen from Earth. Conversely, you’ll have no luck spotting the Small Dog around July 16, which is when the Sun is in its area. ’’ This refers to the fact that Procyon’s rising occurs slightly before that of Sirius, the Dog Star. Astronomers measuring Procyon’s motion in the mid-nineteenth century noticed it didn’t move through space in a straight line. Instead, the star seemed to wobble back and forth as if acted upon by an outside force. It turned out that the outside force was a companion star.

50 by 130 dimensions. Its size, by the way, makes NGC 2403’s area 47% as large as that of the Full Moon. Small telescopes show this object as an indistinct haze roughly twice as long as wide, with a bright central region. Through a 12-inch scope, you’ll begin to see the galaxy’s spiral arms, but you’ll need an even larger instrument to trace them all the way back to the nucleus. Look for stellar associations in NGC 2403’s spiral arms. Associations are a type of star cluster resembling open clusters but larger and holding only up to about 100 stars.
