Suspected infra-red variables in the region of M27

Messier 27 (NGC 6853) or the Dumbell Nebulae is perhaps the most
conspicuous of the planetary nebula and was the first to be
discovered. Planetary Nebulae are formed by a "dying" star shedding
its outer layers in a series of stellar explosions, leaving a 'halo'
of gas and a white dwarf star in the centre.

Although imaged very frequently by both amateur and professional
astronomers little attention has been taken of the very red stars that
can be found in large numbers in the immediate neighbourhood of M27.
The aim of this short project was to identify these stars and to then
monitor them for a minimum of 12 months to see if they were variable
in brightness.

This project will run from October 2007 until October 2008.
