Omega Centauri, improved processing.

[tilbrook@rbe.ne (Justin Tilbrook)]

Hi,

Here's my latest image of omega centauri, taken last night with the moon up. I wanted to image it in moonlight to compare with my first effort back in march, which was also taken under the same conditions.

I think it's a big improvement on my first effort!
Both versions supplied.

Hope you like the new version.

Telescope 8” f/4 astrograph on a HEQ Pro 5 mount, orion mini guider.
Unmodded Canon 1100D at ISO 800.
32 x 60 sec subs ISO 800,
20 dark frames, 16 flat frames and 11 bias.
Stacked in DSS and post process in Phototshop.
Cheers,

Justin.

Okay, I've finally found those tags! [I need glasses]

Yes, the second is much better - very good actually.

Nice Justin, however when you open it in PS the black point is clipped on the histogram

Thanks Mike, Steve and Trevor .

Yep clipped in the black again, usually happens when I'm trying to filter out the blue moonlight background.

Any suggestions on this ?

Cheers,

Justin.

Justin had a go check the histogram on this don't know if you think any better or worse brings out the blue a bit more Omega is full of blue staglers, processing can be a lot of trial and error

Cheers

Thanks Trevor,

Your right about trial and error, sometimes I think I've got an image right, then have a look the next day and it needs more work.
Some times I end up with a dozen different versions.

Cheers,

Justin.

Very nice improvement Justin. It is always rewarding to be progressing in the right direction. All the best.
