Without filter the Tarantula is bluish:

and another picture I took with a UHC-S clipin :

which is more red (due to Halpha pushing which is alsp passed by a UHC-S but NOT with OIII). I took the puctures with a Canon 6d.
The natural color of an OIII is bluish green, so color balance has to be adapted, hence my more reddish Tarantula.
