Dragons!

My first forays into Monochrome Narrow Band.
William Optics Z81 (6AIII Flattener Reducer)
Zwo 8nm Ha, Oiii and Sii filters.
30 x 60 seconds each band.
Stacked in DSS and combined in PS.
SHO starless and with Stars from the Ha channel.

I'm apparently getting a set of RGB filters for my birthday, so should be able to get stars in their correct colours then.

Cheers,

Hugh

You've got a really nice feeling of depth to the images. I like that.

Lovely images!

Can we clarify for my ignorance: are all the dots stars? or are there artifacts mixed in?

Great images
I thing with Ha O3 and S2 you can tweak the colours better than you claim in post process, RGB is good for the stars but the narrowband filters is where the party's at.

Thanks Nik,


I'm converted now. There is no going back to OSC for me!

Both colour pallets are clever and thoughtful. The composition is exquisite with the bonus PN. Whatever noise is present is uniform and not intrusive at all. The stretch is also clever and highlights bright bits without busy distractions. Well done, a pleasure to view!
