LRGB imaging and light poloution filters ?

[Neo_uk]

Hi,

Just a quick question when imaging with a mono camera and LRGB filters is it still advisable to use a lpr filter in conjunction with the LRGB ???? or would this affect the image ?.

second question,

h apha filters ? are they like a heavy duty lpr filter or do they only pass the h alpha spectral line and no other colours ?.

If you suffer from LP use the LPR filter - if not, leave it off. Using the LPR filter would increase the exposure time somewhat.

H Alpha filters cut out all other wavelengths - they are not a heavy duty LPR filter.
