Well this is about 2 hours of data. 12 300s L, and 12 200s 2x2 RGB. I haven't processed the core too carefully, and bearing in mind there is not a huge amount of data, I would be interested to hear what you guys have to say about this image. :blink:

I think this is pretty good for a first attempt with a small amount of data :) You do need some careful processing to get the core right and it would be a good idea to check that you're not clipping the white level in the cores. Check the ADU values in Artemis when capturing subs. I think you're just about in though near the limit with those exposures. HTH :)

Thank you Gina.

What are the ADU values to which you refer?
