M30 is a relatively small, bright, condensed globular that makes a fine target for small telescopes. In larger scopes it resolves nicely into a tiny patch of stardust.

This is one of a series of images that I have been taking to explore using relatively simple equipment and techniques. This is a good example of a patrol image; a quick’n simple image taken just to see what a target looks like. Looking at mjy notes this is only the 3rd time that I have imaged M30, so for me it lies a bit off of the beaten path. I have since visited it several time with my visual gear and it makes a fine target while star-hopping across Capricornus.

M30 is currently well placed to the lower left of Jupiter in the evening sky.
