G2V calibrated CLS filterd RGB v's HaRGB

[MikeD]

I have recently switched from L-Ha/R-G-B imaging to CLS filtered/G2V weighted L-R-G-B imaging and now have some comparison data as requested by Tim.

Both images use the same luminance data from last week with colour added from the two different colour data sets.

The first image is coloured with L-Ha/R-G-B data from 2012 as a colour layer.

The colour data was .....

Ha = 8 x 900 seconds

R = 23 x 300 seconds

G = 21 x 300 seconds

B = 21 x 300 seconds

a total of 7.41hours for the colour

The next image is the same luminance as the first but with G2V weighted RGB data, the G2V ratio used was R = 2.5, G = 1, B = 1.44.

the colour data was .....

R = 3 @ 1500 seconds

G = 7 @ 600 seconds

B = 5 @ 864 seconds

a total of 3.61 hours for the colour.

Note there is no Ha data used in the second image.

the 2nd image is still a work in progress.

I need more Luminance data and I would also usually shoot more colour data, but this was my second attempt because my first go at G2V calibrated RGB, was shot using a ratio of

R = 1.38 G = 1 B = 1.37 but that came out very green ( lesson learnt don't try to work out G2V ratios under cloudy conditions ) .

Stunning images!

Both stunning images. I cannot say I have a clear preference

The colour processing for the 2nd image came a lot easer than the 1st.

I may also need to tweak the ratio a little on the red but the fact that I did not need to shoot any Ha data means the CLS filter is going to stay in the imaging train.

Very nice images the detail in them is fantastic and both have great colour

[MikeD]

Thanks.

Here is the final image with more luminance data.

I just came across this thread, great images mike!

How are you finding the h9 compared to the 916, have you noticed much difference and if so in what respect?

Cheers
