Hello all
Even with 17" of aperture at f6.8, this object requires significant cumulative exposure.
Otherwise known as the Ghost Nebula of course, this LRGB image is 18 hours in total. I pondered for a while as to why the vast majority of the stars in this image had this brown tinge to them and kept going back to check my RGB. Then I realized its all the dust!
