IC 4665

IC 4665 is one of the brighter Milky Way clusters missing not only in the Messier Catalog, but also in the NGC, because it is so loose and coarse. This cluster, located in Ophiuchus, is a good object for binoculars or wide-field telescopes such as the ED80. The cluster is estimated to be 36 million years and at a distance of 1,400 light years. Also, IC 4665 is heading towards us at 12 km/sec (source: messier.seds).

So I imaged IC 4665 from the Happy Frog while waiting for M24 to appear from behind some trees. I think selecting objects to image will be much easier once I am done with the Messier catalog as I just have to point to whatever object happens to be visible at the time I am outside. That is pretty much what I did for IC 4665, I was not planning imaging it, I just had the time and it was in the right location for me to observe it.
