Sorry, but I needed to change M8 photo. There was a great mistake on first processing.

By absolute unknowing about this DSO, I wasted much time erasing the pink color of nebula. But the nebula IS pink ! Trying to recover its color was a great error !

I worked a new process and now it worth !

Very nice looking M8. I always try to use the star colours to balance the image if I can. Your 5128 shots are too vibrant in yellow to me, but the images themselves are good.

Cheers,
Cam

Nice going Jorge, Nice views, interesting flicking between the two gals, different stacking progs produced different field perspectives : ) Colours are more neutral in the 1st i like most, Lagoon looks very good , sharp detais are great, be interesting to see larger if possible ?
Good show ! !

Thank you Cam, Bob and Lucas.

I feel the same about yellowish on galaxy. There's not a pattern in color matter. I saw that galaxy with many diferent colors. I tried to reproduce the majority.

Not so bad. I can reduce the yellowish.

Unhappily I can't publish larger images. I have no web space to do it. And it's a truth, some photos lose quality with great reduction.

I worked a repro of M8 to better show stars's color and nebula. I saved it a bit larger, but with less jpeg quality for 200kb limit

And a bit larger (25 %) repro of ngc5128
