The constellation of Aries is getting to a nice height before midnight at the moment. The three brightest stars are worth looking at through a telescope because they are very different. Hamal (alpha) is a bright orange star. Sheratan (beta) is a slightly less bright, white star. Mesarthim (gamma) is 2 dimmer white stars of the same magnitude, very close together. I imaged all three and put them on to one image. Hamal and Sheratan have the same exposure. I cut down Mesarthim's exposure to show the 2 individual stars.

The Mesarthim stars are very close together, (7 arc seconds), but can be split with even a very small telescope. I could just about do it with my old childhood 40mm refractor. The 2 stars are around magnitude 4.5, but the combined brightness is 3.9.
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.

Nice shot. I consider double star shots rather neglected. Also, Aries isn't photographed very often.
How can I be one with the universe when we don't know what 96% of it is.
