I tried for this one also, first night I only got 8 Subs before getting clouded out, the second night 13 Subs before the clouds did me again.
Not quite as nice as Andy's and Greg's. I recon if I could get a few more Subs and get the noise down a bit, it won't be too bad.
Subs done with an ZWO ASI071 OSC 300S each. I'm going to have to go to mono sooner or later.
P.S. Getting those arms out is not easy.
Cheers
Peter
You've gotten a lot of core detail and the knotty/clumpy star regions in the right hand tail.
Very nice. As you say more will tame the noise more but its looking pretty good.
Greg.
Thanks for your comments Greg. What made the difference for me is finding the SubFrameSelector (about 2 weeks ago) Process in Pixinsight, it will graph the FWHM of your stars in each of your Subs which makes it easy to remove outliers Subs where the stars exceed a certain chosen value, as in the above case 2.3".
It makes a big difference to the sharpness of your image when you get rid of those outliers Subs.

I read in one of Merlin66(Ken) posts, that Melbourne skies have a seeing average around 2 to 2.5" . Having now gone back through some of my past pictures using the SubFrame Selector, I totally agree with him. When I went back and looked at a couple of pictures that have always niggled me because of a slight blur, I found that the stars in the Subs where around 3 to 4". "I have learnt my lesson now" as they say in Engineering, crap in gives crap out.
Very nice Peter, I know we always want more out of an image but...honestly is a ripper. Great job indeed!
Hi Daniel,
Thanks for you comments. The thing I love about this forum (I should spend more time in it) are some of the brilliant images produced by its members. I don't expect to get to that stage, but at least it gives me something to aim for. Each year I get a little better at it. I once read "as long as your happy with your images, that's all that counts" and I agree with that sentiment. I'm happy with the above image, but a bit more data to get the noise down further would make me happier(its a shifting baseline).

You're welcome, great image to look at as is. 100% and I wish I had more time for this hobby, I really do. I have the asi 1600MM Pro, I'm really itching to use it one day (coming from a D610). But my family life and my Olympic lifting takes to much of the pie
You are correct as long as you are happy with the result that is all that matters and some more data is only a click away (with the help of some clear skies). I think we are lucky to have the technology available to us to capture these mind blowing targets. I would love to see what we can do in 500 years, that would be very interesting
I agree it just needed a bit more data.
Cheers,
Tim
Hi Tim,
Thanks for your comments. Judging by the weather we have been having down here lately, it is going to be a while before I see more data happening.

Hi Dan,
I was very active in my 20's and early thirty's in Astrophotography (film days), then came long the kids, study, work and I dropped out of Astronomy altogether. It wasn't until I retired about 7 years ago that I go back into it, believe me once the bug bites it never leaves you. I don't think you need to wait 500 years, in the next 20 you will see astounding progress. This is assuming light pollution doesn't totally destroy our hobby.
Probably needs a bit of saturation boost for the colour though as it's looking a bit monochromatic.
If the skies ever clear again, I'm sure you'll be gathering those additional photons too!

Hi Andy,
Thanks for your comments. Yes, you are dead right, the saturation can come up a lot more and I will address this problem when I get a few more shots and reprocess the image. My great hope is that after the full moon we will have a string of great nights, "the eternal optimist".
