Hi,

thank you for sharing this first result.
It seems to be quite similar to the STC duo narrow band.
the stars are dimmed.
Ha is more visible, but it’s not obvious for OIII, maybe it will with several pictures integrated.
what about the coating of the filter, are they any halos around brighter stars ?

CS, David

Hi Andreotto,

That’s a nice result/picture!
we can even see some OIII around the crescent nebulae.
and it seems that there is no halo around the stars, but they are not very bright.

have you tried the filter with other targets?
