Great to see you back up and running and what a come back. Two very cool shots. Heaps of details in those fields.
Cheers Marc. Yes, I'm pleased to be back up and running, let me tell you. Processing is a little rusty but progress is being made.

Thanks Rick. Sure are plenty of small fuzzies on display. I procrastinated over the brightness of the background as a lighter background can emphasise such features but I'm not too keen on light backgrounds so kept it relatively dark. Some would say the background looks clipped but histograms are clean. Thanks for checking them out!

Your NGC300 is divine.
Greg.
Cheers Greg. Pleased you liked them. There sure are many galaxies this time of the year, too many to image and do some justice on anyway.
On NGC300 there is that strange grouping of bright blue stars and a bright nebula right at the end of the top left hand spiral arm. It almost looks like a companion galaxy. You don't normally see that in a galaxy.
Robert may know something about that. Is it a companion galaxy?

The structure is part of the same galaxy. The area you point out is a more vibrant region being less obscured by dust. This also explains why the HII knot is a deeper red. The other HII knots are reddish-pink due to the scattering a blue light from the young stars reflecting of dust. Similar phenomenon as M20 where the Ha area is pink due to the scattering of blue light. NGC300 is believed to be gravitationally bound by NGC55. I'm not aware of any possible companions in the immediate area.

Thanks Peter. Rusty processing have not worked on any images for the last three months. Workflow needs improvement, but it shouldn't take too long to get up to speed again.

Simply excellent
Thanks Peter. A few more tweaks the set up will be humming. Guiding issues are now resolved but tracking could be improved. Just pleased to have something on the table at this stage. Thanks for the feedback.
Cheers Steve. Would be good to see the 14.5" in action on IC5332. It's rather faint. In hindsight 30min lum subs would have been a better choice than the 20min lum subs used for the IC5332 image.
Yes, great to see you pulling in some photons again Jase. Processed to perfection as usual. Great stuff!
Thanks for appreciating the images, Rob. NGC300 is rather mainstream. I have a couple of long focal length mosaics which the system will probably start collecting data on early hours of the morning in a few weeks time. We'll see how they work out.

Cheers Geoff. IC5332 is a favourite that I've been wanting to image for sometime. The spiral structure leads all the way into the nucleus which I found fascinating. A true spiral in every sense of the word. Pleased you liked them.
Excellent to see you up and running Jase !. Very tight and sharp pics, I can see some other galaxys in both fields.
The weather has suddenly become atrocious since you started imaging, murphys law smacked you hard right there ;-)
Thanks Fred. Wasn't smooth sailing with a few software glitches and guiding problems (two TSX bugs along the way which are now resolved with the latest build and PIR guiding angle related retrospectively). The system is nearly bedded down configuration wise to a point where its doing dusk and dawn flats automatically (when needed) and collecting around seven hours of data in between which isn't bad for this time of year with the short nights. TPoint model needs to be redone as one of the bugs impacted the accuracy. Was hoping to get that done this weekend but as you say, the weather has turned for the worse albeit completely unrelated to me starting to do any imaging

IC 5332 is indeed a faint bugger so you have captured it very nicely.
NGC 300 is excellent too, I like the highlighted HII as well (Greg probably doesn't though )
Looove all the background galaxies too
I notice odd star shapes in both images though what is causing this do you recon?
Mike
Thanks Mike. IC5332 is my pick of the two. I can't find many amateur images of this. Perhaps you can give it whirl. Interesting pick up on the star shapes. The flare around the stars don't agree with deconvolution which explains the odd shape. The raw subs are near perfect but a primary aperture mask would likely clean up the optical path further. There are a few other ways to address this with processing such as relayering the master as a star mask that is not passed through deconvolution which I may progress with in the next few images. Thanks for the feedback.

I was going to shoot IC5332 actually but man, there are just sooo many cool galaxies to chose from this time of year
Hey I am not one to see a great image and only comment on the star shapes and to me they don't stop either image from being visually very appealing I was only asking because I noticed them and was a little surprised, that's all they look elongated virtically and slightly diamond shaped to me

what is causing this do you recon?
