Some nice images there, especially NGC 253 , well framed , captured and processed with very little data
Not sure about filters with galaxies though , my Duoband plays havoc with the colour when I shoot galaxies in Sydney, so I only shoot them down the coast in the dark with my 8” ( no filters )
On the other hand the Duoband has been tremendous in Sydney ( Bortle 8 ) imaging nebula etc...
