So far we've made 176 observations spanning 89 hours over 16 nights. These observations have covered about 5% of the full sky, and about 7.5% of the Northern sky.
There are problems with searching for transmissions in the optical bands since light wave lengths shift with respect to acceleration when veiwed from a distance. band.
All types of EM radiation are affected by traveling vast distances across space as they encounter magnetic and gravitational fields and propagate through the interstellar medium. Frequency shifting, dispersion and absorption affect both optical and microwave (where traditional SETI work is done). Optical frequencies have the advantage of far less dispersion and greater transmission efficiency compared with microwave.
Infra Red would probably be the best.
