Description

This famous object really do not need much introduction.

This is a HaRGB image while most of the other high resolution images of the Ring that I have seen are narrow band images, which may make this one a bit special. It contains more Ha data than most of the others from LT data that I have processed, which helped a lot to reveal the outer shells of this planetary nebula.

Filters and exposures used:

sdss-r 17 x 90 s

Ha 15 x 120 s (mixed 50:50 with sdss-r for red channel)

Bessell B 21 x 90 s (blue channel)

Bessell V 16 x 90 s (green channel)

So totally 1.85 hours of data stacked in Nebulosity 4 and processed in PS CS5
