Let me know if they are what you are after I will upload them.

Thanks.

Also, it is possible that my RC8 is not in perfect collimation, I did notice those asymmetrical halos as well. But I wouldn't ex...

Also, the galaxy remained green when doing what you asked in the IIS thread. Screen shot attached.
