M34
« on: August 31, 2018, 08:40:34 PM »
Thought it was about time I took some pictures...
M34 taken on 30 and 31 Aug.   15 x 300s of RGB giving 3.75 hours of data.  Processed in Dawn which took less than a minute using the defaults.  Then adjusted the colour balance and levels a bit.
Would anyone like the subs to see what proper processing can achieve?

Hi Kathleen,  I've sent a link via a message.
The obsy has been in use for over a year now and I love it.  So much better than setting up and taking down in the garden each time there's a clear night.   :D

I've downloaded a trial version of Pixinsight and had a go at reprocessing my subs.   I've been following the practice used by Kayron Mercieca in his blog - http://www.lightvortexastronomy.com/  His tutorials on Pixinsight coupled with Harry Page's Videos - https://pixinsight.com/forum/index.php?topic=1167.0 are pretty amazing and without them I'd have been lost.
To get a better image I clearly needed more calibration subs. So, after making 200 Bios at 0.001s plus 20 darks at 300s plus 20 Flats of each R,G and B at 0.002s, I could now start reprocessing.  With cleaner subs I could get a better stretch and bring out a lot more stars and better colour.  Somehow this version is swapped 180 degrees left to right.   I wonder how and when that happened.  Life's little mysteries!

Very nice John. Re the obsy, this is why I gave up on the imaging and went to visual. I was fed up setting up and taking down on my small back garden with a limited view of the sky. I envy you and all others who have an observatory and a wide expanse to photograph.


Best wishes

Nice John, yeah the resulting image is much improved I have to say.  Sorry I never got near having
a go at processing your subs yet.  Its a sad statement re the weather though that I have none of
my own to process.

After learning a bit more about PixInsight and reprocessing several times I think I'm done ( for now  ;D ).
There's a much better colour balance and the stars are not washed out.

Hosted on AstroBin now as the jpg is nearly 4Mb in size.  In PixInsight it is 61Mb.   :)
