Iris and Praying Ghost Nebula - reprocess after 5 years

Frustrating having all these clear skies and not being able to use them because of Astronomical twilight, LP and a Full Moon, so I thought I would go back and re-process an image I captured at Olly's place in 2013 and see what 5 years of extra processing experience could do.

I re-stacked from scratch - YES I found all the images and calibration files on my back-up drive.

Taken from Les Granges, Provence, France
Luminance 12 x 900secs, Red 4 x 600secs
Green 3 x 600 secs, Blue 6 x 600secs,
Using Olly's equipment, Atik11000, Takahashi FSQ106N and Mount Tak EM200, Baader filters
To be used in an Edition of Stellarium
This is a huge crop of the full frame posted below.

I look at my old images and wonder if I could make them better. I know that I couldn't do near as well as you have done.

I like your new photo of Carole.

It is always worth going back and re-processing as your processing skills improve Richard.

Thanks David, yes I am pleased with the Iris, the ghost is a bit small and probably need a more powerful scope to do it justice.

Lovely. I think the newer version has more contrast and clarity.

Thanks Jason, I didn't control the stars very well in the original process 5 years ago.
