Helix Nebula

I have been working on this project for a year now. I started collecting data at Clayton Bay before I sold the property. I then accumulated some of the data at home before moving the imaging rig out to our new centre at Swan Reach Imaging.

I am pleased to say that seeing at Swan Reach continues to be very good on most nights; much of the data in the image has been collected at Swan Reach Imaging.

The image contains band passes of L Ha OIII RGB. Most of the data is the Ha and OIII to capture as much of the outer chevrons as possible. It would need another huge effort of over 100 hours to capture all I captured last time and more. I did not have that luxury this time around. Perhaps in the next apparition I can collect another 50 hours of Ha and OIII to add to it. As it is the image contains 44.7 hours of data.

One thing that is more noticeable this time around is the number of background galaxies in the image. There are many within the field of view.
