M28 is a bright, condensed globular that reminds me a bit of M80 in Scorpius, and like M80 is has a flashy neighbor (nearby M22) that can draw your attention. Looking at my notes this is only the second time that I have imaged this object. M28 is a wonderful patch of stardust against the rich star fields of the galactic center and makes a fine target for small telescopes.
This is one of a series of images that I have been taking to explore using relatively simple equipment and techniques. This is a nice example of using these techniques to capture quick’n easy patrol images of potential targets for later follow-up with more detailed imaging or for visual observing.
M28 is currently in the southwest at sunset.
