Last Eta for a while (Ha)

[dugnsuz]

Hello all...

While trying to avoid the full moon, I managed to capture 60mins of Eta on the opposite side of the sky before it sunk westwards.

This will probably be the last Eta from me until next time she's around!!

Canon 40D (modded)
Astronomik 12nm Ha EOS clip-in filter
Canon 300mm f4L IS lens
HEQ5 Pro mount

Cheers

Awesome Doug, Lots of detail, well defined.
Very nice.

Nice shot:)...lots of detail but a bit burnt out around Eta. Well that's what you get with a LBV in the neighbourhood!!

[dugnsuz]

Thanks Carl - didn't get a chance to take any shorter exps to do a layer mask, so I've only got myself to blame!!:P

[dugnsuz]

Cheers Paul:thumbsup:

Great shot ! I'm really enjoying the latest Ha stuff.
Happy with the 300mmIS ?

[toryglen-boy]

Nice image there mucker. loads of detail, better than i could ever do !!

;)

[dugnsuz]

Thanks David...agreed, there's some nice toe-dipping into Ha showing up on the forum now. Marc's Swan was a very recent goody.
I've tended to approach Ha as a supplement to my RGBs, but I think I'd like to explore pure ha imaging further - love those very tight stars and all that detail!!!

I'm very happy with the 300mm f4L. Also performs very well with the 1.4x extender at 420mm which is a major plus too.
Have used it less in the daytime than I have for astro work, but loved the sharpness and IS function at a recent soccer match.

Good one Doug. I wonder whether a 16 bit CCD instead of the 14 bit 40D would still give you a burnt out core? Increased dynamic range might give you more latitude. I'm not sure. Just wouldn't like to start doing multiple exposures in Ha.

[dugnsuz]

You should see my 10min Ha Lagoon for the ultimate in burned out cores Craig!! I'm resigned to taking a variety of exposure lengths for specific objects in both Ha and RGB images (although I didn't in this case!) - just the way it is with DSLRs I suppose.
How goes it with you?
Doug:thumbsup:

ps...got to add that I'm quite impressed with the Ha sensitivity of the modded 40D.

I love the monochrome it gives it the eerie menacing look

Looking good Doug, Eta is all but to low to get anything of any value here now. Always next year. Maybe the clouds will clear by then.

[gregbradley]

great detail and nice and bright but a bit burnt out in the core losing detail there.

Try lassoing it, feathering it 25 pixels and shadows/highlights or curves to get the detail back. It'll be there.

Greg.

Spooky Trev Spooky!!



We should all be experts by the time Eta's at the zenith again Doug!!!:P



Thanks for the advice Greg, gave it a try. Just cant get the central core to yield any detail - too burned out.
Anyone...feel free to play around with the image! just tellme what you did!!!!
Doug:thumbsup:

[TrevorW]

Shadows and highlights in CS3

your originals is on the left

reduced brightness of core

you asked for it :thumbsup:

[dugnsuz]

Did you apply it to the whole image as opposed to just the core Trevor?
Whatever you did I like it!! (Apart from the increase in background noise - points off!!:P)
Seems to have brought out some more detail in the nebula though.
Doug:)

[TrevorW]

To the whole image Doug

yeah noticed the noise but thought you'd get rid of that

:thumbsup::P

[dugnsuz]

Lazy bugger!!!:lol:

[dugnsuz]

The last "LAST" one...

[TrevorW]

Promise

core looks better
