Re: WTS: BNIB Baader 3.5nm HA filter (50.8mm round unmounted)

Bump.

It appears that Baader has released the OIII and SII versions, so you can get the full package of sub-5nm NB filters for a fraction of the cost of astrodon or chroma.

Re: First Narrowband Attempt

Awesome shot! And thanks for the mention :D Narrowband is indeed quite challenging, but I'd say that one learns something new each time doing it (especially in the processing). In terms of acquisition, it's usually a case of "the more the merrier". I see that you have a nice roll-off observatory too...

Re: Window Astrophotography 2019

Beginning a project on NGC 3576, The Statue of Liberty Nebula, in SHO palette. About 6 hours of exposure so far, but I think there is more nebulosity in the surroundings that can be further extracted.
