A bit of an update on this imaging run.

So far I have 580 minutes of Ha data and 495 minutes of luminance. The annotated luminance image attached shows that there are a lot of fainter background galaxies showing through, however there are many that are not being picked up by the catalogs I selected. Some of those that have been selected are around mag 20, so I am assuming that the smaller fainter ones are getting around Mag 22-24 or fainter. I am also starting to see what appears as a extended halo to the NGC55 too. I will keep plugging away to determine if it goes any further out. Doubling of the data should show that.

The Ha data is looking pretty good now, with the fainter jets and loops showing a bit easier, however they are not bright enough yet to show up in a colour image. Again, a doubling of the data should give greater clarity. The bubbles and knots are also very interesting to look at in the Ha data.

So for now I keep persisting.
