M33 Close up

[DaveS]

And still not entirely convinced

This is:

25 x 900 sec Hydrogen Bin 2

44 x 600 sec Luminance Bin1

16 x 600 sec Red Bin 2

18 x 600 sec Green Bin 2

16 x 600 sec Blue Bin 2

A lot of work in AstroArt 8 including DDP, Deconvolution, Selective Colour Attenuation, Saturation Boost, and a light Unsharp Mask to finish.

I don't know about the luminous haze running from top right to bottom left. I had thought it was another gradient, but @geoflewis has looked at earlier versions and thinks it's the outer envelope extending beyond my F0V.

In any case, I could probably do with more data, but not sure what would make the most difference for a one-night sequence. More Luminance seems a good idea, but any other suggestions?

[geoflewis]

I still think it looks good Dave.

[DaveS]

Thanks Geof.

[tooth_dr]

Looks good to me too, pinpoint detail and a delicate amount of saturation.

[DaveS]

Thanks Adam. I had to be very careful with the saturation as it was very easy to make the image clown like, yuk.

A fine M33, great definition and I think the silvery blue for the spiral arms is spot on. I would agree that the luminosity extending out in the corners is from the galaxy, it seems to have a more diffuse structure that a lot of spiral galaxies.

Looks awesome! i love it!
