SPX350 F4.53, ATK-16HR, Baader RGB+Astronomik IR742nm filters.

Tried some more obscure Terzans over Winter to compare RGB with IRGB and contrast is certainly improved in Sco/Sag dusty areas, cutting through the orange glow. Interesting to see IR stars switch on at 742nm but not show much in Red broadband.

RGB=8x3min each.
IR=8x5min.

In order Terzan 9, 10 +11 showing IR IRGB first then R RGB.

Thanks, John.
