The scopes are C14’s.

The value of unfiltered measurements is immense.  See the number of papers in the BAAJ or other (professional) journals which contain unfiltered data from amateurs to see just how important they are.

Simple patrolling for outbursts for example – deeper images unfiltered or less exposure time.  Time series observations during outburst are just as valuable unfiltered – it’s the period and amplitude which are important here, not necessarily the intrinsic brightness.  And of course, an unfiltered observation is better than no observation at all!
