The South Africa Deep-Sky Journal Nightfall has two new DSO publications available for free download.

There are a few articles of interest to northern observers in...

Thank you, Jimi. From you, that means something.

If ever you want to write something for us, we'd be delighted. We're fully aware of how out-front you are. The email is assa.nightfall@gmail.com....

South Africa's Deep Sky journal Nightfall has been publishing for only two years and has produced 10 excellent issues so far. We are now listed on an international content aggregator as an online...

Thanks to an offhand comment about runaway O stars, I looked into the literature on this and got a surprise. It turns out that an eye-brow-raising 20% of all the O stars that...

I will send you a PM, Preston.

Hi Steve, pardon the delay, my observing site has no wireless or cell access. I can’t recall the exact paper that mentioned the cluster Fornax 6 is actually an aggregate of field and Fornax dSph red...

The Fornax GCs are considered as strong evidence for DM. Their orbitals are too distant and high-velocity for the galaxy's visible mass; the DM is thought to be 11 times more massive than the galaxy...

Akarsh, the Fornax Dwarf is nearly overhead Nov-Dec at my lat of 33°S. I've spotted 1049 and Fx 2, 4, & 5 with a Mak MN61 at 174x and Santel 180/1800 at 163-200x. Fx 6 is not a GC but small asterism...

Addendum to Uwe: Your small triangle of stars edging Pyx are mag 15.1, 15.5, and 16.1. The cluster's brightest RGB is 16.3 and the HB/RC is 19.25. Koposov 2014 (arXiv:1403.3409v2) suggests an...

Thank you, Uwe, for the Wd1 and Pyx GC info. I'm doing an article for the NMASSA S African newsletter, re adapting professional astronomer field-count methods to verify visual observations. My skies...

Can any of you confirm observations of the Pyxis GC and the massive young cluster Westerlund 1 in Ara? What were the observing conditions, location, and equipment?
