Hi

Got some luminance in 2.5 arc sec seeing and some colour in rather poorer seeing. There is not enough data to extract detail and still control the noise, but it is OK for now. I have a fair bit more lum data taken under worse seeing, but it doesn't add to the image - now waiting on really good conditions .

Colour was a bit red/brown overall from extinction, so the blue (and to a lesser extent green) was enhanced to compensate (hopefully). It was nice to see a little bit of detail on the disk.

The negative version of the luminance shows many of the large number of globular clusters around this galaxy, as identified by Rolf in his post at http://www.iceinspace.com.au/forum/s...ad.php?t=92183

thanks for looking. Ray
