IC434 HorseHead

[Brad Moore]

Hi All,

After goofing around with polar alignment for most of last night, I decided to give it a break and take a quick pic of IC434 with a HA filter.

If you have a LCD monitor:
Standard (http://www.southern-astro.com/imgs/temp/ic434-lcd.jpg)
Full Image (http://www.southern-astro.com/imgs/temp/ic434-full-lcd.jpg)

If you have a CRT monitor:
Standard (http://www.southern-astro.com/imgs/temp/ic434-crt.jpg)
Full Image (http://www.southern-astro.com/imgs/temp/ic434-full-crt.jpg)

It’s a bit short on the HA data as you can see from the noise in the image. Oh well, I'll just have to go for a longer exposure next time.

I'm interested in feedback from people with CRT monitors on how the image looks? Is it to dark or just right?

Cheers,
Brad Moore

very nice!!!

laptop for me, do you add colour later?

i got a glimpse of the nebula thru the ep just the other side of the main star ther night. how much fainter is that than the horsehead side?

[davidpretorius]

mate, the std size is simply lovely, i like it without the colour!

roughly what exposure?

That is excellent!!!!!!!!!!!!!!!!!!!!!!!!!! !!

On my old CRT monitor it is perfect! Both Versions. Brightness & Contrast is spot-on.

Absoluetly amazing pic. Congrats :thumbsup: :thumbsup: :thumbsup:

omigosh

what a wonderful image

h alpha rocks!

[Brad Moore]

I think you need a large aperture telescope to see this visually and really dark skies it has a really low surface brightness. I'm not really a visual guy, so I'm just guessing. Maybe someone else can jump in.

Cheers,
Brad

Thanks! The exposure is 30 mins. Its Hydrogen Alpha image. I might add some colour to it later. HA+RGB.

[Brad Moore]

Thanks for that. I find it hard to set the correct gamma.

Thanks,
Brad

I hope you enter the Astrophoto contest at the Snake Valley Star Camp for the 'Erwin van der Velden' Award! Come on up and have a ball!

From memory wasn't this nebula found first photographically and then if you knew what you were looking for see it in a big dob at a dark sky site.Nice pictures Brad I can see the thin wisps rising like soft spikes.Very hard to image.

Once I'm fully setup I will do a 12 hour HA shot on this. :). I had really good seeing last night. Around 1.6 arc-sec FWHM.

Cheers,

I had a look through someone's 20 inc dob with a h beta filter at the last SPSP and saw -rather imagined- a shapeless blob

on the other hand Phil Harrington has reported that he has observed the horsehead with a 10 x 20 binos so there you go!

[avandonk]

Try H alpha?

Awesome! :eyepop:

Bert, it was a h-beta filter. I was there with Narayan and saw it too. A most unremarkable object, visually.

Great shot Brad.

and yet worth tracking down mike :)

i only have a lcd at work but it looks sharp here.. i might try at home on the crt

[TidaLpHasE]

:thumbsup:Great shot, i have an lcd, the lcd pic is a little darker than the crt, but it still shows the same amount of detail, with what seems less noise.

Awsome even without color:thumbsup:

Very nice Brad.....we dont see many HA images in here..

Lots of detail.
