25 October 2019 - Las Cruces, NM

From my new darker location in Las Cruces (moved in October 2019), the very faint Integrated Flux Nebula (IFN) can be seen - bottom Lum-only image. Much more easily seen than in my prior work from my location in the north/bright part of of the city! The IFN is a little-studied complex of diffuse dust and clouds in our own Milky Way Galaxy ~ (text from APOD).
