<Sigh> Weather here continues to suck! This image was taken over 4 clear moonless nights during 2 lunar cycles (!), and then only gathering 8 hours of usable data (seeing, clouds etc)
In any case, whinging aside, here is NGC 3521 - a "Flocculent" galaxy in Leo. The seeing was average (on a scale of excellent-good-average-fair-poor-hopeless). The image scale has been reduced by 25% to mask some of the artefacts from a relatively small integration time and average seeing. I managed to show off the bright colourful core and the "bubble" easily and the dimmer halo elements also came out reasonably well with some pushing. There are some fainter arcs and streams further out but there's no way I could get sky dark and clear enough to be able to render them.
