Hi,
I have added flats I took to my Omega Centauri data and wonder if the flat is OK. I used Al's virtual lightbox and did 20 x 5 sec exposure on each LRGB channel and adjusted the light box brightness on the computer screen so the histogram was in the same spot for each filter. Could someone pplease have a look at the images as when I did my first curves stretch I got a couple of camel humps in my stretched histogram in the levels box. The humps were there as soon as I opened the curves box. Advice????? Take up another hobby
Thanks
Mark
