Our collection consists of broad band and narrow band filters. For broad band
imaging we have several sets of BVRI filters, which are not meant
to leave their telescope. Our set of narrow band filters at the moment
is still rather limited, except for (redshifted) H
filters, of which
we have more than 15. All filters are square, and have a length and width
of more or less 50mm. Some of the larger filters do not fit into every
filterwheel. There are however filterwheels
to accomodate each filter.
