I set out to get closer images of certain Messier objects I had seen in my wide angle images from a previous night. I've posted three images, all taken with a Canon EOS 70D with a Canon EF 70-2000mm 1:2.8 L IS II USM telephoto lens.
Image 1: M7 and M6. M6, or the butterfly cluster, is in the top right of this image. M7, of the Ptolemy cluster, is in the right center of this image. They are both open clusters that are a part of the Scorpius constellation. This image is a stack of 2s exposures.
Image 2: M8, M20-25. M8, also known as the lagoon nebula, is on the right just below the midline. Above it are M20 (the Trifid Nebula) and M21. At the top center of the image is M24, the Sagittarius Star Cloud, a globular cluster. Counterclockwise from there is M25, an open cluster in the Sagittarius constellation. M22, the Sagittarius Cluster, is in the bottom left and appears almost like a smudge in this image. This is a stack of half second exposures.
Image 3: This is a very similar shot to Image 2, but shifted a bit more to the right. Additionally, it's a stack of 2 second exposures so has more stars included. I'm particularly happy with how M22 and M8 have shown up in this. Further, M23, an open cluster, is visible in the top right.
Map! Man, that quality went down in conversions. Ah well. You get the point!
Cool stuff
