NGC 3532 Football Cluster

The data for this object were captured during April and May as part of a fill in activity whilst in between other imaging projects. The cluster on the right is NGC 3532 also know as the Football Cluster. I can see the football shape so can easily see why it is called that. RGB exposures were limited to 60 seconds to avoid over saturating the stars and the Ha exposures were at 30 minutes with a view to capturing the faint nebulosity in this area.

Exposure details are:
Red = 87 @ 60s
Gre = 77 @ 60s
Blu = 84 @ 60s
Ha = 28 @ 1800s

I was attracted to this object as I felt that the stream of Ha that appears to emanate from the cluster provided a different perspective for the image. The surrounding area is home to many well known and imaged objects such as the Running Chicken Nebula, the Carina Nebula and the Southern Pleiades. It is good to get off the beaten track a little and present a lesser known object.
