NGC 6543

[AstronomyUkraine]

This is 11 hours of OIII on NGC 6543. I took advantage of the moonless nights to shoot the OIII. The stack consists of 66 - 600s subs. I will need to take some shorter subs to try and tame the core a little.

Crikey!  Fascinating image. Some lovely detail. Would you need to use some kind of mask to dumb down the centre of the cat's eye?   Gary

Thanks Gary. I will take some short exposures then blend them together using HDR Composition in Pixinsight. I doubt it will completely dumb down the core, but it should improve it.

Wow! Both for the quality of the image, and that you managed to get 11 hours of moonless nights!

Thanks Padraic. Yeah it was a big surprise to me too. We had a good spell of clear weather here, and it's still ongoing.

Good grief, that's a really amazing image Brian. Not seen that one before either.

I think you've had more clear skies in a few days than we've had since Christmas. The Eastern side of the Uk is messed up at the moment.
