Hi Folks
No doubt you have all seen more than enough Eta Carina images.
I thought I would share this one with you, due to the comment received when I posted it in another forum.

Fellow ASSA member Chris P. quickly commented "Looks like a Rat eating a block of cheese"
And indeed it does.!

I had been staring at it for hours while processing it, and never saw it. LOL.!
just goes to show what a fresh set of eyes can pick up.

The tech bits : 31 exposures @ 120sec using an ASI1600MM cooled to -20C, via Ha filter, thru a 200mm Tamron Tele lens of 1970's vintage.
Software included PHD2 guiding, APT for capture, DSS for stacking including bias, flats, & darks, and Photoshop for some minor contrast and cropping adjustments.
Taken at an astrocamp in March, which was the easy bit.
The hard bit was the processing.
Still not sure what I am doing, though this result has turned out OK to my eye.
Next steps as time permits : add in some RGB when I learn how.!

I like those really small, pinpoint stars. A nice image.
But.....
Be buggered if I can see a rat eating cheese ;)

Same here, Rob.
The majesty and magnificence of Eta Carina reduced to a rat eating cheese ...

Looks like you are going along very well with the image. I look forward to when you do add some RGB,
Cheers,

Thanks Tim
I look forward to mixing in some RGB too .... but the required learning curve, plus 8 very busy weeks coming up... means it will be a while away yet
cheers

I like the image and especially with Mick's enhancement - should have gone into Bintel's Carina challenge.

Oh Man...

We have been having issues with rats at home (And a hyper excited terrier when he nabs one at 2AM) and now I am going to be seeing rats outside every time I look south too!
