[ATMoB-discuss] Day Star Filters

[mmotta at massmed.org]

I have one of these.
They are NOT the same as the Coronado
filters and should not be interchanged.
Each works as a system.
The IR blocking filter goes on the front
end as a prefilter, the rest of the
T-scanner goes on the focuser, and is
tuned there. The Scanner must NEVER be
used without the prefilter in front of
the objective.
