LRGB imaging and light pollution.
I'm about to delve into LRGB imaging and have a question about light pollution.
I have and use a Astronomik cls ccd light pollution filter on my 5D MKII. It works really well and enable me to stretch my subs out 6 or 7 mins in my very light polluted sky's.
Question: do I still use my CLS filter with the LRGB filters?
I would imagine I would still use the filter?
I'm yet to start my research on LRGB imaging, can you recommend some good resources?
Thanks
