It's such a good area of the sky.

thanks Allan - sure is some interesting stuff up there.

many thanks Clive. The galaxy is so interesting that it seemed to be worth posting regardless of quality.

thanks Lee. I used Nebulosity, which has a software binning function. works the same as binning on camera, but adds 4 "read noises" rather than one - if you have a low read noise camera though, it can work out to be almost as effective at noise reduction as perfect hardware binning. Nice to be able to use it after the event.

thanks very much Rick. will now look up 1097. EDIT: sure is a remarkably similar structure in 1097A. Almost looks like shock waves or ripples - although the "fluid" of a galaxy must be quite different to liquid or gas, I guess that the maths could be similar in some ways?

Thanks a lot Allan. As far as I can tell from reading, it seems that the interaction is generally accepted to be taking place - NGC1316 is 100 million years into the process of dismantling NGC1317.

Greg.

Thanks Greg. Could have done better, but that is not always possible - nice to have something to post in any event and was a good way to develop some new processing skills trying to dig something useful out of the noise floor.

Regards Ray
