A challenge for Ann, find the two globular clusters!
I can only find one, near bottom, at about 5 o'clock. It is very obvious. But as for the other one... nope!
So help me, okay, starsurfer?

Hi Ann, Look for NGC 6388 - to the far left of the frame at 10 O'clock.
Cheers
Andy
Wow, thanks a lot, Andy!

NGC 6388 is a bright yellow thing that looked like a star to me! Admittedly, it
is a bit fuzzy at the edges.
That means that the other globular, at about 5 o'clock scraping the bottom of the picture frame, is NGC 6352. And the moderately bright bluish star at 8 o'clock is Sigma Ara. And that moderately bright bluish star at about 5 o'clock (but pretty centrally located) is Iota Ara. And the bluish "double star" located almost dead center of the supernova remnant is SAO 227972 (the brighter component) and SAO 227966 (the fainter component. The stars appear to have very similar proper motions and possibly parallaxes, so they may be physically related.
None of those two stars is a supernova remnant, that's for sure!
