Im a Infinity user too. Good shots

Maybe not overstressing the histogram would avoid these overexposed areas

At 20x30s with my light pollution it's hard to keep the core from blowing out. What do you do exactly?

[elpajare]

I only act with the Histogram. I move the Black bar to the right next to before the signal starts and then I move the White bar of the Histogram to the right or left until I see the object without overexposure, usually just when the visible signal starts with intensity in the graph. The central bar tried not to touch it. Then I save the photo and adjust it in detail later in a PC program.

I leave all other settings by default.

And I do not exceed 15 "of exposure in these bright galaxies, do not worry if the photo does not look very good on the screen with subsequent corrections will improve a lot. I have an 8 "Newton too.

As a program of retouching the photos I use the one that Mac has by default: iPhoto

It is a personal opinion anyway.....

Yes it's personal opinion but it's nice to read how you go about it.

I've been setting the white bar very far right and the black bar pretty far left. Then adjusting orange bar to suit my tastes. I'll try your method!
