Greetings from NP 991 & 992!

However, I don't think anyone compared brightness. According to stellarium, Jupiter is indeed brighter than the two stars you mentioned, but would the difference be important enough to be noticed. Also, did you compare the original frames, since the stitch is likely to change the luminosity and size of the dots.
I did, with two samples of each starnet.
"Jupiter"(?) looks brighter than I thought at first, and certainly brighter than Kaus Australis (epsilon Sgr), Girtab (theta Sco) and Fomalhaut, but it's debatable as to whether it's actually brighter than Altair, let alone, what, 13.8 times brighter? *shrugcringe* But this is a reduction and projection, and not perfect. (We can also see that Even KausAus seems dimmer than Girtab, when it should be the other way around...) So I'll let it slide. (I've also since found the reasoning for 13291, and am quite impressed.) Just something that was bothering me, though...

Third planet??? Did we find a third planet?
