Large mag image, critique sought.

[tilbrook@rbe.ne]

Hi,

Imaged the large magellanic cloud last night, and would really like to know if I'm on track.

Camera Canon 1100D
Lens 75 to 300 zoom at 75mm F/5.
ISO 3200
10 light frames and six darks.
Processed in Deep Sky Stacker.
Tweaked in Photoshop.

Any comments appreciated.

Cheers,


Justin.

Justin,

Your focus looks really good on this. I think you need some more data to tame some of the background noise. But despite that this has heaps of potential. I can see some color in the Ha region sjust wanting to come through and I think with the right processing you could bring that out.

Also you should be able to reduce those magenta rings on the brighter stars with a decent mask in Photoshop and some use of color balance or hugh saturation tool.

Tough subject but you are off to a great start.

Hi,

Thanks so much for your advice.
It's a real minefield navigating my way through camera settings and processing, any advise helps a lot.

I'm imaging the small magellanic cloud at the moment, I'm aiming at 30 minutes of data. I've also improved my polar alignment and tracking speed, of my portable mount, also stopped down to f/5.6.

I'll post this in the next day or two, hopefully with better results.

Thanks,

Justin.

You've done really well with that lens.

I tried using it once on the Pleiades, about 5 years ago, and gave up very, very quickly. Admittedly, the version I was using was the image stabilised version. f/4-f/5.6, non-L series lens.

It has horrible chromatic aberration, in general. I think that's the cause of the magenta stars in your image.

Nicely done -- keep it up.

Really nice shot. Bit more saturation on the colors if anything but it's top shelf as it is. Well done. :thumbsup:

Nice shot Justin and yes, your on the right track.

Hi,
Thanks for that.
Iv'e tried more colour saturation and can't seem to pull any more out of the image.
Has anyone got an image that I could use for reference?

Thanks,

Justin.
