Well I did last fall when it got out on the street, but that was only in Halpha http://www.narrowbandimaging.com/cbu...er_ha_page.htm I pushed the image hard to reveal it.

I need some new memory but mine is many decades out of date I'm afraid. Is it more an OIII object? Rick

I haven't tried it and no longer have that sensor in my camera.
