Here's my first attempt at combining H-alpha with a LRGB of the Lagoon.
Instrument - Tak FSQ, G11, camera QSI683wsg8, astronomik filters.
integration times: L 16x 120s, R,G,B 8 x 300s, Ha 4 x 1200s.
Image taken from suburban Perth.
This was another hole-in-one polar alignment, I used the compass to align the tripod, and just put the G11 head in place! No other adjustments.
Comments and constructive criticism welcome.
