M90 LRGB

hi all,

I added color to my m90 image. LRGB 80:15:15:15 mins RGB 2x2 bin taken with a Takahashi Mewlon 250 at f9. Processed in MaximDl and PaintshopPro.

There are some gradient problems I have to work on.

comments welcomed

Hmmmm....the noise level in the color data is kind of high. I think you will need much more color data to get accurate color in the dim portions of this galaxy. With an 80-minute luminance, you would need at least 40-minute exposures for good color. Anything less, and the noise in the color is likely to dominate.

In effect, your long luminance exposure is holding a very bright light to the color data, and the luminance image will reveal any flaws or noise in the color. The solution is to brighten up the color with longer exposures so that they are more nearly equal.
