Thanks Troy. Its the O111 that is the blue and I looked at the O111 master again and its definitely there. A lot of the data was imaged using the Trius 694 which is 66% QE in O111 which I think is the most sensitive of any CCD plus it was on the RHA which is very fast at F3.8 so it collects a lot of light very quickly. Perhaps twice as fast as many other scopes. 12 inch and F3.8 is a good formula, demanding in terms of precision but the advantages are the speed of data collection. I think its ideal.

So its picked up actual O111 that probably is not normally picked up. But I did check the processing of colour after Marcus commented on that and I did tone down the blue compared to where it was when he commented. So its less blue than it was!

Greg.
