Color Correction with Light Pollution Filter

[redarmy27]

Good morning gents.
 

I got to get out and experience a warm evening in Minnesota with my new Tokina 11-16mm f/2.8 on the Nikon d7100 on my iOptron Skytracker. I was pretty impressed by the quality of the lens but did bump up the aperture to 3.2 to try eliminate some coma prevalent at 2.8. Some still existed but it was passable.

Anyways, I was using my Hutec LP clip in filter for my Nikon and was curious about eliminating the blue hue that it gives the images. Any thoughts... on what temperature to edit the photos with? It does make it much easier to contend with LP since I'm right outside a red zone, but I don't want to over color correct the blue to kill off the actual colors of the night sky. Any thoughts?

Additionally, does anyone ever have any difficulty focusing on stars with the filter in? Sometimes I feel like it's harder for me to train in and achieve proper focus with the filter in.

Thanks in advance!

All the best,

Jake
