Scientific paper

A two-week campaign of high-resolution imaging of the centre of M15 using the
tip/tilt correcting TRIFFID-2 camera, followed by analysis with ISIS (image
matching & subtraction software), has produced the most sensitive survey to
date of variable stars in the central ~1x1 arcmin^2 - a total of 48 were
detected -, and constrains the size of the dwarf nova population.
