Recently we talked about making files availible so people could have a try at image processing.
I have uploaded a image file of NGC 5189.
file is zipped and is 144kb, unzipped size is around 900kb.it is in BMP format so should be able to be viewed by most if not all image processing software.
here is the address
http://members.iinet.net.au/~westsky/NGC5189.zip
The image is 50 images x 30secs
taken with a C11 at f6.3
Go ahead and have a go and let us see what your results are like.
cheers
David.
