1h 21min of integral Ha and SII exposure of immediate surroundings of Beta Centauri (Hadar) showing surprisingly complex structures not so noticeable in G or B broadband or OIII exposures (and barely visible in SII and R exposures) - captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope on 3 imaging sessions carried out on Mar 28, Apr 1 and Apr 2 of 2023.
The SII, Ha, SII exposures are mapped to RGB channels and additional color corrections are applied in post-processing. The OIII exposure was intentionally not used because not even hint of these structures is registering on it.

https://www.astrobin.com/ojtcmx/C/Since the attempts to find any previous optical images that would show the full structure of this nebula or even explicit references in the literature were unsuccessful so far (as of Apr 16, 2023, albeit its presence is found in several all-sky surveys which were reveling no internal structure or just a hint of presence - as identified during the discussion in Forum thread [4]), it is possible that these are the first color images of this object ever obtained in the visible spectrum![4]
