SH2-114 - The Flying Dragon

[Wyvernp]

Afternoon All,

This one has been quite a while in the making as it seemed to get brushed to the bottom of the imaging pile, I finally pulled my finger out and finished off taking the RGB subs for the stars. and  couple of extra Ha subs.

Antlia Ha 3.5nm 36mm: 112x360" (gain: 139.00) -15C bin 1x1
ZWO 36mm Blue: 16x60" (gain: 139.00) -15C bin 1x1
ZWO 36mm Green: 16x60" (gain: 139.00) -15C bin 1x1
ZWO 36mm Red: 16x60" (gain: 139.00) -15C bin 1x1

Please do feel free to critique, it's mostly why I upload these as it's the best way to learn.

Nicely framed image Wyvern, and one I've never attempted.

To me the image seems to have quite a lot of noise. I had a go at reducing the noise using the jpg posted but then I lost a lot of the detail. Any chance you might post your RGB and Ha fit masters so I (and maybe others) can have a play. Now we're in Tier 2 (and no doubt heading for Tier 3) I've got no plans to go anywhere so I've time to play

Sure thing,

The HA was taken at a couple of camera angles hence the crop.

Thanks in advance for the assistance.

Everything downloaded. Strange though that Blue is there twice but I seem to have everything.

All sorted - not sure what was going on but I've got all four files.

I'll have a play and see and see what I can do.

Thank you

 

[Wyvernp]

Good stuff. Thank you!

In the meantime I have reprocessed and come up with this which I think is a little better.

[Wyvernp]

I have to say I'm not happy with the Ha data overall. I'll probably revisit this as soon as it's in my FOV from my back  garden but with 20m exposures

I think that is much better - my attempt is not significantly different.

I would be inclined to reduce the noise a little more but that is just a personal preference.

I've taken the liberty of reducing the noise on your image.

That is definitely an improvement. What process did you use to reduce the noise?

I used MultiscaleLineartransform on the Ha component on mine. perhaps not enough.

That really is a lovely image Wyvern.

I also used MLT in PI on all four channels whilst they were linear. Once combined I took the finished image into Affinity (you could use PS) and manually applied Dfine2. I have an old copy of Dfine2 from when it was free to use - DxO now charge for it in their NIK Collection.

This is a new one for me. Love it! 👍
