White Balance Problem ?

I don't use photoshop- I do most of my photo editing in GIMP, which is basically a free version of photoshop. So, I'm not sure how well these instructions will translate to Photoshop. In GIMP, if you go to "Colors", then "Levels" you will see a heading titled "All Channels" and under that 3 droppers (one black, one gray, one white). You can use these to set the WB. For example, if you click the white dropper, then click on a white area in your photograph (or what should be white, like the NGC slab), it will adjust the WB so that the slab becomes white. You can do the same with the black dropper and an area on your photo that should be black. The middle gray dropper is if you are using a neutral gray card or something similar.

Alp I think photoshop has something similar. I never used it because I didn't realize it adjusted white balance. I thought it only let you change the color of the area you clicked,

I have both types of ott lights. The two I always use, one diffused and one not, are LED. The third looks like a desk lamp with a six inch narrow fluorescent light

I imagine if I edit in raw I can still save it as a jpeg to put in photobucket.

All good advice. Thanks

In the guided section of photoshop you can select "remove a color cast". You can use the eyedropper on a white black or grat area of pic.
and all colors are corrected.
