Veil neb (Witches Broom) in Ha

[ChrisLX200]

Not exactly ideal conditions last night with a near-full moon and occasional clouds and mist (and judging by the way the guidestar image wobbled the seeing was not great either). Narrow-band came to the rescue though and I was surprised how well this came out despite the permanent twilight sky!

My usual gear for this: NP127is, Atik490EX, Lodestar, Baader 7nM Ha filter.

6 x 20min subs, total 2hrs, stacked in DSS and processed in StarTools.

Nice image. Lots of detail despite the challenging conditions. H-a is great for cutting through the haze and murk, isn't it.

Thanks, Ha is great! I took a few Lum images to start with - white out

Narrowband imaging is still a difficult task when the Moon is Full,yes H-Alpha doe,snt do a bad job,but O111 is very prone.

You have achieved an excellent image here,one full of intricate detail,something that is often shown to its best with pure H-Alpha image.

Nice one.

What a great mono image!! Well done Chris, this is looking super!

Thank you Sarah, appreciated

Yup, this is good, with the forward shock fronts coming into view. I agree that Ha is only partially moon proof. For the faintest details a dark sky does help.

That's a lovely image Chris. I guess we're all doing H-alpha at the moment with the Moon situation. However, when we next get some moon-less nights i'd encourage you to collect OIII data to supplement this image since the Witches Broom looks great in HOO bicolour (lovely reds and blues inter-twinning) and already you have a great looking H-alpha layer.

Thanks, I did try for OIII a couple of nights ago but it was something of a disaster, misty conditions resulted in massive halos. For a laugh I'll post the result...
