Hi all,

I have been lurking and experimenting for a while and thought about time I showed something....

Taken when moon set in am of 6/3/09..from very light polluted skies of Sydney
15 x 4min subs;
no light pollution filter;
Canon 350d modded;
lx90 @F10;
stacked and aligned in DSS;
97 flats;12 darks;24 bias frames
guided with Skywatcher ed80 and DSI ProII and PHD;
processed in Photoshop CS...

I wanted to share the 'improvement' (i think so anyway) from one with little processing to the current one...even though I may have overdone the processing a little, I think there is improvement there...I used DDP sharpening in Photoshop courtesy of this link www.pk.darkhorizons.org (http://www.pk.darkhorizons.org) (choose ddp processing from tips) and a bit more selective sharpening/blurring....

Alex

[Edit] - LH pre-improvement RH-post improvement (attempt anyway!!)
[Edit] PS - would really appreciate people's feedback on whether I have mashed it or fixed it....mine is an LCD screen - thanks Steve...
[Edit] fixed link - thanks Greg

Very nice result Alex.
Is the LH image the pre-improvement?
Because, to me anyway, that has more impact.
I'm certainly no expert though, and I'm viewing in daylight
on an LCD monitor.

Pete W does a great thing occassionally and posts some
images for the benefit of LCD users and CRT users.
Not quite sure what the difference is that he applies but it
certainly works.

Thanks Steve.....

yes the LH is the pre-improvement and, what I was really doing, although did not make it clear was asking if people thought I had improved it or totally mashed it!! :)

So, would very much appreciate feedback on whether I have mashed it or improved it.....

Thanks...

PS - mine is an LCD screen....

Nice work. You could try a bit of gaussian blur on the background to reduce the colour noise.

The link to the DDP sharpening did not connect.

Thanks Greg......I will try some gaussian blur and have fixed the link....I think i just need to get out to a darker sky and try again...or maybe a LPS...
