Refried Chook

[ReaPerMan]

When I last posted this data (http://www.iceinspace.com.au/forum/showthread.php?t=102147) I had never taken a Ha pic before and my fist attempt left me thinking about doing better.

here is my reworking and It's a bit more how I would have liked it to come out the first time!

All advice gratefully received. Thanks for looking

Paul :thumbsup:

EDIT

Added the old picture for direct comparison


NorthGroup ED127mm APO, QHY10, OAG and Lodestar Guiding. MaximDL, Processed in CCDStack v2, Post in CS6. 13 X 600 sec RGB (OSC), and 6 X 900 sec Ha Bin 2X2.

Looks excellent, Paul!

Looking much better Paul, definatly improving your Frying methods, slowely but surely is better than Hot and crispy, but some like hot & crispy, chicken that is ;)
Nice show ! !

That's the great thing about astrophotography there are so many ways to arrive at a result. Some changes and new tricks can lead to a completely different outcome from the same data! Changing the 'menu' for the fried chicken led me to a completely different look. More detail, more color and less noise. Since taking this shot I now know to use the red channel only from the OSC for the Ha giving a larger pic than the 2 x binning in this one. One of the tricks was in the first attempt I enlarged the Ha to the same size as the RGB, in the second go I reduced the RGB to the same dimensions as the Ha. This was the solution to reduce noise. I can't wait to get some data on a better subject the chook is 'tasty' but like most chicken dishes it needs a bit of spice to keep it interesting.

All the best

Paul :thumbsup:

That's very interesting. Huge difference though. It looks great.
Would love to see a comparison of with and without Ha data especially since they're taken with an OSC. Something I'm dying to try out as well.
I still think taking all at 1x1 would yield good results. worth trying.
Did you use CCDStack to scale it down?
is your Ha 7nm?

Cheers

The Ha data provides a lot more detail to the finished product. The guide that I used was on the Starizona website and I followed the type 2 process to get a HaRRGB. I have produced another Ha picture with the Ha data at 1X1 Binning. You bring the OSC pics into CCDStack and tell it to extract the R channel everything else gets chucked.

I resized the picture with Photoshop. My Ha filter came to me from Gama Electonics when I got the QHY10. I'm not sure of the brand and I think it's a 12nm (low on $ at the time :mad2: ).

All the best

A big improvement Paul - better detail and hues in the nebula, star colours are better and the star shapes look rounder in parts where they were previously elongated. Nicely done!

[ReaPerMan]

Thank you David,

There is so much to learn and now that I have a few more tools in my processing pencil box I look at my older attempts and there is a large temptation to reprocess a load of my old pics to see if I can improve them too.

All the best
