NGC6188 in RGB and NB

[avandonk]

I blended RGB data with NB data using a secret recipe. The method minimises the effect of the white NB stars on the colours of the RGB stars.

RGB data 15x5 min for each.

NB - NII 13x32 min, OIII 10x 32 min.

Hi Bert,
I really enjoy having a scroll around the field. Have you considered trying the "lucky imaging" technique with your equipment?
