Hi Brendon nice shot well done

She's a nice shot Brendon. The highlights could be toned down a little though.
Glad you got some clear skies.

good goin mate!

I think the black point is a little low, and theres either too much sharpening or contrast in the processing, but the data itself looks sweet!!

Really nice and wow! how much data you got it there!

Nice work Brendan.

I wonder how it will look structure wise after Eta pops its cork.

Cheers

Brendan,

Nice image, and nice contrast.

Brendan, plenty of detail but I think this is over cooked. I reckon you should take the sharpening back quite a bit. Just my opinion though.

I second that Paul. Definitely too much and too much contrast. Other than that, good stuff!

good afternoon all, well i finally got time to re process my eta ha shot, i left it in the red channel and mixed in the red and green chanels just to bring a bit more of the faint stuff out (only one red in the bayer matrix and 2 green

) comments and opinions more than welcome!

Yep this looks better than the first image. What about the rest of the data now?

bmitchell82 (Brendan) · #12 10-12-2009, 05:21 PM

what do you mean by that? the RGB?

Paul Haese · #13 10-12-2009, 05:24 PM

Yep that is what I meant.

bmitchell82 (Brendan) · #14 10-12-2009, 05:37 PM

presently i have 1 image in RGB problem is its rotated by about 60 deg

though ill slip it together and rotate to "enhance" my other image

bbs

aligning the 2 images has proven very difficult aka i cant get them to line up satisfactory i need something like registar to align them properly, other wise the ha as a luminance is all over the shop.

Maxim will compensate for this Brendan..

Its a pretty easy process, takes no time at all and works wonders for me... Worst comes to worst, manual rotation and alignment of the two frames in photoshop.. this can take HOURS!
