WebThe requirements for photometry are not trivial. A telescope, preferably an all reflecting Classical Cassegrain but any good scope will suffice, a steady and accurate equatorial mount, a good mono CCD ideally without anti blooming gates, a set of UVBI Johnson – Cousins photometric filters or at least the V filter, a computer with appropriate ... WebUV photometry has been crucial in discovering and analyzing these MPs, but the Johnson U and the Stromgren and Sloan u filters that have generally been used are relatively inefficient and very sensitive to reddening and atmospheric extinction. In contrast, the Washington C filter is much broader and redder than these competing UV filters ...
