Dave- very nice work! What is causing the blueish tint on the Clavius image?

Bruce

Thanks Bruce.

The QHY5LII-C RGB slider defaults at the time I captured were set to RG equal and low value, with B a high value. Hence the blue looking image. I never worry about visual colour, preferring to sort in processing. It was really to test that the latest QHY SDK update was functioning.

I usually carry out lunar imaging with a QHY5LII-M - this has a sensor QE of 78% (versus the 53% of the colour sensor).

I have a few filters with different Wratten numbers now. I will be investigating the effects of these. Up to now #25 red (15% transmission) seems to steady the atmosphere, while the #56 light green (50% transmission) seems to give good contrast.

Dave

Thanks much for the explanation.
