Date/Location
Notes |
21 May 2025 - Las Cruces, NM
This image is LRGB - note the Luminance contains all of the detail, as
shown in my blog.
Main target here for me was NGC 3389 (the one with
"structure" just left of center)... also shown here is NGC 3384
and just out of the frame is M105 (you can see part of it at the bottom of
the frame). NGC 3389 is about 72 million light years away --- and FURTHER
way than the other two by roughly 20-30 million light years! |
