Wide field ngc5128

[Peter Ward]

Last night's data. The seeing was not bad for a change.

The image is reproduced at about half size. LRGB 60:20:10:20 mins.

nice image peter, good to see youre able to get out and amongst it and get the fresh data, a number of noticable faint galaxys in the background too.

like the idea of the greyscale at the bottom of the image, its so hard to know if your own monitor sees it just right at times.

Cheers Alchemy

Played with the image a bit in Photoshop...slightly different presentation here

lovely image Peter, very fine and subtle details

Nice work Peter. Not much else to say. May favourite amateur image of this galaxy is that performed by none other than R Jay GaBany using Brad Moore's 12.5" RC - http://www.cosmotography.com/images/small_ngc5128.html

Pleasing to see your rendition.

A lovely image of one of those great galaxies you never tire of viewing.

I like the way you have captured the extensions of the dark dust lane as they drift of into space.

Cheers

Nice image, good scale. Is that nebulosity to the lower right?

don't know...probably my neighbors' flood light !

Nice image Peter that displays the galaxy in its finest. Love the littlies in the background.

[skeltz (Rob)]

nice image pete crisp and sharp.

FANTASTIC Peter
You have captured the outer halo of the galaxy beautifiully. It is one HUGE galaxy when you take that into account. You can also see that the Halo extends out at the pole of the galaxy (to the bottom left of the image from the galaxy). I love to show this detail in the scopes but I have rarely seen these details in a photo.

Thanks Andrew! I suspect you are a true artisan for sure !

Looks really nice on my screen Peter .

Now was that taken with the RC or AP with strings?

Only small critisism I have is that the sharpening causes the star spikes to dissassociate slightly from the center of the main body of the stars and I'm not partial to this look, I prefer to see the spikes taper from fat near the star to thin at the ends...rather minor thing of course but when you are at your level, such minor things are worth mentioning I guess, hope ya don't mind?

This is a joke isn't it?

Err...think I used the RCOS....with strings

There was no sharpening applied to the image. Just multi-pass Gamma scaling.

Was that using a 3 giga hertz plasma rifle in the 40 watt range..?

Does gamma scaling impart a log stretch to the image, if so then it will increase the noise and harshen the stars, yes?

Not always...I use a partial log curve, going easy on the dim stuff but kick the curve back up pretty radically near the top to give stars a snappy look without the dark doughnuts.

Noise was pretty low...two hours of data from a 14" tends to beat it into submission
