It is the only RGB set I got, but I have more IR, methane and also clear filter images. The methane image is a single 5min integration, IR is the average of several 15sec integrations and for RGB I averaged several 3.5sec 4,5 sec and 10sec raws. Seeing was good for some moments. Although the SE disturbance is well seen and there is plenty of activity on the NEB, I will just focus on BA. It does look it has an internal (central) substructure, at least in IR, R and G filters. In addition, the BA methane-bright spot is indeed smaller than the IR and visible counterparts. It also looks round. When superimposing the methane and IR images, obtained a few minutes apart, the BA methane-bright spot appears to co-localize with the BA's (central) substructure, thus leaving a methane-negative periphery. Good observations Antonio
