SPX350 F4.5, ATK-16HR, Baader RGB Astronomik IR742nm filters.
This Terzan is North of Scorpius Tail and a shade south of star 45 Oph. In the dust this would look interesting in IR to see through the dust for better contrast. Notice the star a touch right of the cluster in IR is very bright compared with RGB. If you flick from one image to the other you can see the IR stars switch on and off as the dust disappears.
RGB=8x3min each. IR=8x5mins.
Thanks, John,.
