Ha Horsehead - IC434

[1ponders] (Paul) · #1 16-11-2009, 01:03 PM

IC434, 4/15min, dark subtracted and flat fielded. Levels and curves in PS CS3. Tried to keep the stretching more reasonable than the 2070 post.

Very nice Paul. What's the cause of the concentric rings around the bright star(s)?

Al.

I like the composition, dark and moody, and the bright star ring effect.

I have no idea Al.

That's just how it come out.

I was expecting it to get blown out of the water when I started to stretch it ( as it normally would) but that was how it ended up. May be something to do with Ha???

Thanks Fred. I do like the combo of the WO72 and the H9. It really lets me use the full res of an image without having to scroll all over the place to see the whole image. I'm really hoping to add some more over the next few weeks to try and smoothen it out a bit.

I expected you to come straight back with "oh, that's just..."

. It's not an extension of the Airey disc do you think? It seems awful big for that to me, not that I know...

Some really good details in the HH outline. More data will make it a keeper.

AlexN · #10 16-11-2009, 06:51 PM

Awesome work Pauly!! keep pounding it with more and more subs... What Ha filter are you using?

Alex.

DavidU (Dave) · #11 16-11-2009, 09:02 PM

Sharp outlines and collimation Paul.

thanks for the feedback guys. I'll check on the Ha when I get home tonight and post the details, but from memory its an Astronomik but I'n not sure on the bandpass

<applause>
You're on your way Paul. I agree with Fred, its been a while since I've seen such a dark and sinister looking horse. Impressive stuff. Looking forwarding to seeing more of your Ha adventures. Surprise us!

[1ponders] (Paul) · #15 17-11-2009, 08:46 PM

Thanks Jase. I'll certainly keep at it. There are so many objects I want to try this on.

I'm hoping to get some time to try a re-process on this and NGC2070. I'll see if i can reproduce this effect. I'll also try your suggestion Narayan and see how it looks. I know what you mean about having a blown out Alnitak.

Hagar (Doug) · #18 17-11-2009, 10:40 PM

Lovely dark horse Paul. Alnitak is a bit unusual but the rest looks great. Looks like this camera and Ha filter have hit a nerve and a good one too.

Omaroo (Chris Malikoff) · #19 17-11-2009, 10:57 PM

A really nice example Paul. Love the mono.

I did a short one last weekend too, but won't be putting it up after seeing yours. LOL!
