Next one from the Sharpless catalogue of faint nebulae.

It's not a common object, and of course... it's faint.
 
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
Always taken pictures of the past, something that happened 7500 year a go and now arrive to the earth.
 
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

That looks like an interesting target and the color blend you've produced is very striking. Thanks for sharing your result.

 

My only negative would be that at larger scales the background looks a little over processed (pushed too far?). But, as you noted, it's a faint object and you've captured a lot of detail in the nebula itself.

That's right, also the star reduction that i don't complete manage right well produce this results. If you look on the original results with all the stars.. it's to much.

At the end, I need more data acquisition.. but this will be for the next year laugh.gif

thank you for your comment
