SH2-176: one more big, weak, old PN

[stephane zoll]

Good evening,

The weather last week was rather good around Grenoble ; I took this opportunity to finish the acquisition of the weak planetary nebula SH2-176, in Cassiopea. Total exposure = 7h in Halpha + some RGB subs for the color.

Which gives:

N&B Halpha :

Inverted:

And very high contrast Halpha version :

- Taka FSQ106 f/5

- CCD Atik 4000 (-20°C).

- Astrodon R, V, B & 6nm Ha filters

- Halpha: 20min subs, total 7h

- processed with PixInsight & CS3

Not so many images of this one on the web. My resulting image is not so spectacular but I found the target challenging

Clear skies,

Cracking image Stephane, so much star colour. Must be a very faint planetary.

Very fine image Stephane....great star colour and a good capture of a very faint object.

Cheers

Beautiful stars. Very very nice.

Good one Stephane. I haven't seen it before. Nicely combined Ha and colour.

Very good skies here to the South West of Grenoble. I hope you are getting them too.

Thank you, Marc, Rob, FAP.

This PN is probably the weakest I ever imaged. Just above the background signal of Cassiopea.

Olly, yes I'm doing some acquisition this week on an other one

This night the sky is not so clear at my elevation ; too much mist, but I am still confident for the next nights.

By the way, what is the elevation at Les Granges ? I should visit you one week end...

I love the colours in this, a typically dim Sharpless object but I love them! Strangely, the colour overcoat has brought out more detail visually.

beautiful shot, nicely processed

[Whirlwind]

Lovely image, I've never seen this one before, beautiful.

[Tom OD]

Lovely image, and I also ike the inverted image. It shows up the background Ha nicely.

Hi,

Yes Steve, I had the same reaction: the colour helps to boost the contrast here.

Thank you Peter, WW, Tom.
