Description

LRGB image of NGC 2903 taken over several nights. Much of the imaging east of the Meridian is looking into heavy light pollution, but I did not use a LPR filter, only a luminance filter after I noticed the LPR did not improve the signal to background ratio possibly due to the broad band nature of the light pollution. This is my first try with LRGB.
