IC 443 Jelly Fish Nebula in Gemini.

[tilbrook@rbe.ne]

Hi,

Been a while since I've posted a new image, been cometing.:)

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini.
This is quite large with a low surface brightness.

ISO 6400 really helped on this, here's a previous effort.

This is one of those nebs that is generally overlooked by southern hemisphere imagers (including me) due to its somewhat northern declination (+20deg) but it's probably not really warranted as it is high enough above most of our southern horizons to give it a good go, like NGC 253 is for most notherners...so well done Justin, nice work :thumbsup:

Great job Justin!

Nice capture :) A lot of nice colour to surf around in.

Nice one Justin. Looks like a brain with tentacles. :thumbsup:

I'm used to seeing this one in narrowband. Looks pretty cool in RGB too, Justin.

Thanks Mike!

Quite a few challenges low in the North, needs an exceptionally good seeing to do any good.



Thanks Rusty!



Thanks Colin! That's one thing I like about my unmodded DSLR it gives good colour range and variation.



Thanks Marc!
First time I've been able to get those faint tentacles.



Thanks Rick!

There's a few RGB images around, more detail in narrow band, that's for sure.

Nice one Justin - a quality image. I hope to be imaging this myself from a northern site soon.

Perfectly processed Justin. Really interesting image. Great stuff.

[tilbrook@rbe.ne]

Thanks Steve!

Are you going to image in RGB or narrow band?




Thanks Rob!

I was surprised how it turned out, found it tricky to layer and balance the faint areas.

Cheers,

Justin.

really neat image - lovely processing.

Thanks Ray!

IC 443 is a real challenge to process, hoping to see some pics from the CCD imagers.

Cheers,

Justin.
