This has been a popular object of late but Ive not imaged it with the EOS Ra camera till now. With a more then half illuminated moon in the sky last night I used the Duo narrowband filter, passes Ha and O3.
9 x 10 mins ISO 3200. 10 inch f5.6 newtonian

Hand guided as usual. Polar aligned to around 10 arc secs so dec corrections not often needed. Seeing wasnt that great, stars appeared to be boiling slightly when checking focus, but the 30x live view makes focusing easy with such high magnification. Brighter stars can be seen in live view even with the filter in place.
