IC434 HorseHead
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
Full Image
If you have a CRT monitor:
Standard
Full Image
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

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.

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,
Brad

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!

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

 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
