This is part of my experiment to get close-up images of brighter deep sky objects using a lunar and planetary camera.
On this occasion there is no luminance data, only narrowband - Hydrogen Alpha, Oxygen III and Sulphur II data combined in various ways using either H Alpha or OIII to act as the luminance channel. All images are a stack of 20-second exposures in 16bit mode.
At the top is a combination of the data sets on the left and right below. In the middle I've used a Hubble style combination which can't be added to the top image without neutralising the effects. The image on the left uses OIII as the extra luminance data and on the right H Alpha as the luminance channel. H Alpha never picks up the central stars in M57, only OIII or a true luminance or straightforward LRGB set can pick up enough data to show the stars inside the Ring nebula.
I will return to this with the intention of capturing more sustained data on each narrowband another night.

Ha = 51x20 seconds
OIII = 50*x20 seconds
SII = 23*x20 seconds
*OIII and SII in particular were meant to have more frames but incoming cloud cover brought my experiment to a halt.
Equipment:
ZWO ASI174MM mono CMOS camera (uncooled), LX200 300mm f/10 SCT OTA, EQ8 mount, 60mm f/13.5 guide scope+ ZWO ASI120MM mono guiding camera
Geordi: Data, look over there! My visor's picking up an old Earth signal from something called "Flickr."
Data: Yes, I see it as well. Interesting. A primative entertainment and recreation network. Perhaps I should attempt to tell a joke?
Geordi: Um ... maybe not, Data.

'Data - is a work that is trying to emulate the style of painting inside the lettering of graffiti in 3d. This is used a lot in all styles of graff to fill out the internal structure of the letter. It actually works well in 3d because you can layer it on top and use it as a reflect/refract material.
My graffiti work has been influenced a lot by product and industrial design lately - with this render I didn't really want a heavy textured object (all though the red has a bump texture on it). I wanted to keep it minimal and give it just a clean plastic feel - trying to get a sense of sleekness and futurism to this work and I think the clean style and color help
There is a wealth of data that shows the value to companies of investing in employee health. It is not always easy to communicate it coherently and encourage employees to participate in wellness programs. GE Healthcare's Health Economics team has made an attempt to get it across in pictures. Watch Raquel Cabo from in GE Healthcare's Health Economics team talk about the data in the visualization.

My d800 is either getting old or getting incresingly creative on its own.

Spotted near the Vansittart Estate in Windsor. It's written in some cement between an inspection cover and some wall mounted trunking. I haven't attempted to translate it!
