Sh2-224 (SN remnant in Auriga)

[Epicycle]

Hi,

we don't see this object too often here at SGL. It's a very curious asymmetrical supernova remnant in Auriga.

I should've left this for darker nights, but it  was just too intriguing. Processing was a pain due to ugly moon gradients

(in spite if the 5nm Astrodon) but more annoyingly, thin clouds getting in the way. In the end I managed 20x1800s subs which

was just about enough to make sense of the object.

Details:

-Megrez 72 @ 4.8 and SXVR-H9

-Astrodon 5nm and; guided off axis with SX mini filter wheel.

-Processed in PI.

-20x1800s =10hs

Comments as always are very welcome!

cheers

Interesting object I've not seen before, thank you for sharing

This is a new one to me as well, and at 10 hours of data you've done really well - it's clearly pretty faint, but is a beautifully structured Sharpless object. Nicely framed & processed too - top notch.

How odd... I was looking at this one last night when deciding what to go for, and decided against it as its supposed to be quite hard. And yes, it must be - because youve had to throw 10 hours at it to get a good image. Well done, tough object.

Patience rewarded!

Oooh yes, something special. Well done indeed.

That is a very interesting and detailed image of a little know subject - excellent, thanks for sharing!

Thanks for the comments everyone! It is indeed quite faint, and I might revisit it next year when the moon is not around. I'm also curious to see if it has any OIII to offer,

If you thought the Ha was faint you'll find the OIII a real rib tickler

Nice capture you have there. Dark and clear skies are a must I feel.

If you want to really stretch the Ha and OIII you could always try the star less method.

Very nice image. Never seen images of this one on SGL. Thanks for sharing

I agree, the OIII is probably almost non-existent. For stretching the Ha I did actually treated the big stars separately.

Very nice image. Never seen images of this one on SGL. Thanks for sharing

I did a not too extensive search and the following came up: http://stargazerslounge.com/topic/195109-sh2-224/ (that's a great capture).

That's a great capture of a very difficult object Epicycle - nice one.

I've not seen this one before. Great image of a difficult target.

I agree, hats off. Mark.

Thanks Ian!

Thanks. Here is a colour image (not by me!) showing also great detail: http://istarion.net/images/Nebulas/Sh2-224/Publish/SH2-224-RGB-Blue-Matts-Sporre-1280C.jpg

Thank you!
