An image of the Great Globular Cluster in Hercules.

The Great Globular Cluster in Hercules

This is the first astro image I took using my f/6 8-inch Dobsonian telescope.

At the time, I was still refining my image processing skills, and this is the best I could make it. This is a stack of one-second exposures taken with a phone attached to the eyepiece.

Stacked with Sequator.
