One of autumn’s best, the open star cluster M34, lurks just 5° west-northwest of the variable star Algol. You can spot the 5th-magnitude cluster with your naked eye from a dark site, and it’s impressive whether you view it through binoculars or a telescope.
M34 holds 10 stars brighter than 9th magnitude spread over an area 0.6° in diameter. A 4-inch scope reveals three dozen members glowing between 8th and 12th magnitude.
