Thanks, it looks like the camera is very sensible to the geen/blue light.

 

Cheers,

I thought my NGC6888 was good, this is another several levels better.    Where did you get the idea to add in Red and Green and how did you add it into the processing??   Thanks!!

Hi,

 

The technical data was wrong, I have corrected it. I captured a full RGB set for the stars only. The image is HaO3O3 plus RGB stars. I didn't use the RGB data for anything but the stars.

 

Cheers,

You've also taken full advantage of the good well depth on the sensor.

It's a gorgeous image!  Thanks for sharing it.

Thanks!

 

I have operated the camera on High Gain mode, thus the FW is reduced, however the noise floor is very low and that allowed me to pull out most of the O3 signal from the noise floor.

 

I am looking forward to use this camera on low gain mode with long exposures!

 

Cheers,

 

José
