Thank you! It was pretty hard to process for some reason. Also it was this image I noticed how much seeing affected the images as it was taken over a couple of nights.

I also used Mike's approach of sum combine. It brought out the dim stuff a tad better than using median combine (which is nice because it gets rid of all the little defects like cosmic rays, satellites and meteors).

Good enough to eat Greg - beautiful depth for such a faint object.

Nicely framed and pretty deep work here Greg and yes you have showed the outer arms nicely, an interesting galaxy.

Psst...I have just finished inserting my new Ha OIII SII Astronomiks set, giving me LRGB & HaOIIISII in the filterwheel now, all ready for Friday night ...hopfully?

Yes I've had a good run. My dark site weather has returned to its default pattern of clear at night about 80% of the time. The formula I reckon is being in the foothills of the western side of the Great Dividing Range. Its probably true almost anywhere on the East Coast on the ranges. The wet air from the coast doesn't make it over the ranges that easily and the weather mainly comes from the west and next stop is Perth via desert inland Australia! On the eastern side of the ranges you get more cloud as the western air which is warmer hits the cooler high humidity coastal air.

Does this mean you'll be able to image from your backyard?
Don't forget to go longer subs with the S11 filter and perhaps the O111 filter although I find my O111 filter is similar in light throughput as my Ha or at least close to it but S11 is pretty dim.

Greg.
