Magnitude: -
Size: 40' × 30'
Distance: 500 million light-years

Skill Level
The faint galaxies in this group require long exposures.

Recommended Equipment
Use a rich-field Newtonian to maximize light-gathering power (though at the expense of resolution).

An SCT will give you better resolution, but you may not be able to fit the whole cluster.
