IC 443 Jelly Fish Nebula in Gemini.

[tilbrook@rbe.ne (Justin Tilbrook)]

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.

8” F/4 astrograph , baader type 3 coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D plus cooler box. 30 x 120 sec subs ISO 6400 Stacked in Deep Sky Stacker .Processed in Photoshop Cs2..

Cheers,

Justin.

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

Great job Justin!

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

Nice one Justin. Looks like a brain with tentacles.

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

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

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.

Cheers

Perfectly processed Justin. Really interesting image. Great stuff.

Thanks Steve!

Are you going to image in RGB or narrow band?

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

Cheers,

Justin.

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

Cheers,

Justin.
