Does this look ok to you?

[martin_h]

The reason I'm asking is because I've removed my LP filter from my imaging train and ended up with some right dodgy results, everything was blue biased!

So I did a G2V star calibration the other night and came up with these ratios R-1.3, G- 1.2, B- 1

And this is the result - but does it look ok to you?

the whole thing looks very slightly yellow to me but I have not attempted to actually measure anything.

Yes, a definite yellow tinge, but a brilliant image in my opinion.

[martin_h]

Any better?

[AlexB]

That looks ace! Can you take flats now to remove the dust spots? I don't know.

[martin_h]

I didnt bother with darks or flats as this was just a colour test

Nice work Martin.

I am going to find out my values rather than guessing them during a colour balance process in CS5 by eye.

Which star did you use as G2V ? Was it near Zenith ?

I used Mizar in U Major...
