Thanks, Paul. It's not the most attractive galaxy (IMHO, at least) and I found it quite a challenge to present it attractively. Still not 100% happy with the processing and I'll probably tinker some more.

Amazed at how much detail you've ended up with given that much of the data was acquired at 2 arcsec/pixel, which for us would be 4x4 binned. Perhaps we have something to learn. Did you use drizzling?
Great shot.

Thanks very much, M&T! Yes, I used drizzle and also weighted the Lum integration using a formula that rewarded FWHM and star roundness as well as SNR. The data from SRO was very good and takes drizzle really well at that image scale. Seeing less than 1 arcsec really does make a difference!

Thanks, Lee.

The data you get from that site is stunningly good.

Ta, Greg. I try to make my images look good at full res which doesn't always translate well to smaller versions, but I may be guilty of pushing the dust lanes too far
It's unfortunate that Astrobin doesn't preserve ICC Profiles. You're probably not seeing the image quite as I intended. Maybe I should start using Flickr links instead...
Cheers,
Rick.
