| Date/Location Notes |
25 April 2020 (added to 25 Oct 2019) - Las Cruces, NM LRGB only. From my new darker location in Las Cruces (moved in October 2019), the very faint Integrated Flux Nebula (IFN) can be seen - I added more LRGB data to the October data - and huge improvement. The IFN is a little-studied complex of diffuse dust and clouds in our own Milky Way Galaxy ~ (text from APOD). |
