M92 is a globular cluster found in the constellation Hercules.
This is a bright cluster and is also known as NGC6341. It can easily be seen even with a small telescope.

This is one of my earliest astrophotos. It is an unguided image taken with my very first telescope, a Celestron C8 SCT on a CG5 mount. A Nikon D90 DSLR camara was used capture the image and since there was no guiding, the exposure times were very short.

The LRGB version shown below was done with a guider. It used more frames and longer exposure times. The difference between the two photos is significant and is a good comparison since both were taken from the same spot and under similar conditions.
