The OPT Triad filter transmits H alpha, H beta and O III.  The first of those was very apparent. Processed in DSS, Pixinsight & Faststone Image viewer.

Looks like you've been getting some good skies in the NE, Steve.

Thanks Jeremy but alas that sky was light polluted.

I was 3 miles from centre of Banbury

Filter has a 3nm bandpass for H Alpha, and an 18nm bandpass for H Beta and O III.

Cheers

Steve
