That's a new one to me as well Jeff.

Fascinating image and quite unusual.

Thanks for posting that one.

Good work there Jeff. Whats the brightness of the HH object, must be close to mag 20? Nice long subs there too

I couldn't find a mag in the catalogs, but using MaximDL it gave around low 19's.

Will try Astrometrica.

--19.6

Yep it would have to be at least that. What colours were assigned to the HA and S2? S2 is also deep red even deeper than HA isnt it?

Assigned Ha as red, SII as green and blue.
I am trying other combo's.

Nice Jeff

Can't say I'd heard of it before either! If it were oriented any other way when first seen it would never have been called "Waterfall", huh!

Hi All,
I have downloaded the latest Maxim 5 on trial. With some reprocessing I have finally finished my image of H-H34. This has closer colours to the HST image that I'm sick of looking at.

I must follow Jase and write down the processing steps as I go.
