Veil Nebula in Cygnus

Hello everyone

Finally a new image, consisting of new data and new equipment.
This 17 hour composition of Ha and OIII data has been used to create an RGB image where the OIII data has been used for both blue and green.

The new equipment is an FLI Proline 16803/CFW5-7, attached to a Bellepheron focusser, Astrodon MMOAG, and Lodestar guider.
The filters are Astrodon Gen2, and the OIII has a bandpass of only 3nm, so it took hours of exposure to build up enough signal, whereas the Ha filter has a slightly wider bandpass of 5nm. The FSQ106/Proline combo has easily framed this huge scene in one go.

I thought you might be interested in 2 versions - one is subtle, the other sharpened to enhance the delicate filamentation. Which do you prefer?

I have not reduced the file sizes, so these are full-sized images, and therefore large downloads.

Subtle full-size version (10mB) - http://tinyurl.com/29pdj6c

Enhanced full-size version (10mB) - http://tinyurl.com/2768brp


thanks for looking

Martin
