Eta Carina TEC180FL redo already!

[gregbradley]

Here is the well imaged Eta Carina.

I haven't done it for a while.

It is one of the iconic southern objects.

TEC180FL, FLI PL16803, Baader LRGB Astrodon 5nm Ha.

HaLRGB 70 80 70 70 80.

Wow...

That's very good Greg but can I have a larger one to look at please

[telecasterguru (Frank)]

Greg,

Great image. Why do you run the blue channel for more data than the R and G?

Greg,

That's very nice, though, the colour seems a bit weird to me (yes, I understand, hydrogen alpha).

Frank, you expose more in blue to combat atmospheric extinction.

Its a misprint I did 70 minutes each of RGB. Sometimes when I save the file the numbers are not available so I did it from memory. But running a bit more blue may be a good idea as it often is slightly less sensitive and as mentioned it gets blocked most as the scope points lower and lower in the sky.

Yeah I had a bit of trouble blending in the Ha. I redid the LRGB mix and Ha blending and it looks better now. Sometimes I add Ha as a luminosity layer but in this case it only worsens the image and colour.

Thanks Marc.



The Ha image is also worth a loook:

The battle with processing Eta C is how to get that solid look in the Ha into the colour image without resulting in a solid red image.
