Beautiful. I love all those stars. Personally, I would be tempted to try to make the background darker. But I wouldn't want to lose any of those stars though.

Great image!

Excellent shot Tyler!
As a note, on my monitor most of the stars show a slight cyan/greenish halo...


Keep it up! wink

Wow, off to a good start.

Is it possible to shoot the core as a separate item like M42 imagers do?

You could then get the dust lanes etc and add in the core to keep it less overexposed.

Greg.

Hi Tyler,

Very nice! I would take more RGB exposures (2 to 3 times as many) and maybe back off on the red a bit as this galaxy has a lot of very pretty young star clusters similar to M45 and this gives it a lot of blue regions in the arms. An object this bright greatly benefits from color detail.

Best,
