Astronomy Picture of the Day - The Double Cluster in Perseus

Explanation: This pretty starfield spans about three full moons (1.5 degrees) across the heroic northern constellation of Perseus. It holds the famous pair of open star clusters, h and Chi Persei. Also cataloged as NGC 869 (top) and NGC 884, both clusters are about 7,000 light-years away and contain stars much younger and hotter than the Sun. Separated by only a few hundred light-years, the clusters are both 13 million years young based on the ages of their individual stars, evidence that they were likely a product of the same star-forming region. Always a rewarding sight in binoculars, the Double Cluster is even visible to the unaided eye from dark locations. But a shroud of guitar strings was used to produce diffraction spikes on the colorful stars imaged in this vibrant telescopic view.

Wow.

At first I thought that was Tokyo on final approach.

The photographer put some string in front of the telescope to generate an out of focus obstruction whch generated the starburst effect.

The Double Cluster is always fun to look at in just about any optical device one might have- any size binoculars, from the smallest to the biggest binocular telescopes. Low power, wide field views, even in small to medium size telescopes are great.

Not a fan of the excessive diffraction effects he introduced...

Speaking of astro-pictures, I just returned from a place called Goblin State Park where we camped for a few days. This place is other-worldly and I highly recommend it if you've never been. One of my primary reasons for going was to photograph the Milky Way (Goblin Valley Park is a registered Dark Sky area). Here's on I took at Wild Horse Butte at the park.

Oh that photo of the Milky Way is like what I saw in Pa. at the top of a Hill in Elk Country in PA. ....it was as you say other worldly...and it seemed like you could almost reach out and touch it all. I sat on the deck for hours watching it as so mesmerizing and beautiful. I don’t think it can be described unless you’ve experienced it.

I agree, there is nothing like seeing a blanket of diamonds in the pitch dark sky. By the way, the larger glob of stars near the bottom is the Milky Way core.

I wish I knew how many times I have looked at the Double Cluster with my telescope...

That and the Orion Nebula are favorites, Jupiter and Saturn of course, Ring Nebula, Dumbbell Nebula and if I can find it, the Hercules Cluster. Huge galaxy cluster...Andromeda galaxy is cool too but not always visible. Can’t remember the names, but several nebulas also in Sagittarius and Lyra constellations.
