Messier 57 (NGC 6720)
The Ring Nebula
Planetary Nebula in Lyra RA 18h 53m 36s Dec +33d 02m 00s

Chris Newsome took the following wide-field image of The Ring Nebula on the 15th July 2006. He used a Celestron
C8-NGT telescope with a Canon EOS 300D camera and an Astronomik CLS filter. The image is comprised of 8 frames of 300 seconds exposure each at
200 ASA. This set-up was auto-guided using a Skywatcher 80T telescope, Meade DSI camera, GPUSB guider interface and MaximDL. The images were
also calibrated and combined in MaximDL, and then processed in CS2 (using GradientXTerminator, curves, levels, high pass and overlay) before
being converted to JPEG format.

The following image of M57 in Lyra was taken by Simon Allcock, Adrian Brown and Chris Newsome on the
evening of 7th/8th June 2005. It was taken through Simon's 8" LX90, with Chris' Meade Deep Sky Imager and Adrian's 0.5 focal reducer!
The image was processed using Registax and Photoshop.

Adrian Brown took the following image of The Ring Nebula M57 in Lyra on 28th May 2005.
The image was taken with a C11 SCT at F6.3 and an ATK-2HS camera. K3CCDTools was used to capture and stack the 21 individual frames that
were taken, each of 45 seconds exposure. Maxim DL 4.10 was used to adjust brightness and contrast. He also used Maxim DL’s Lucy-Richardson
deconvolution filter to sharpen detail in the nebula. Adrian comments: 'I’m really pleased with how this one came out and I prefer this
image to the colour version that I did last time'.

Adrian Brown took the following image of the Ring Nebula in Lyra (M57) in the early hours of the 8th May 2005.
The image was created by stacking twenty-four 40 second exposures taken at f/10 with a Celestron C11 and an ATK-1C camera. |

Tony Razzell produced the following image of M57 (seen at lower centre as a 'star' with a hole in it) in 2004.
It is a combination of four 10 second exposures taken with an Audine camera through a 300 mm telephoto lens. |
