DayStar Filters NEW Quantum SE Hydrogen Alpha Filter Series.

This completely redesigned precision heated housing incorporates ALL of the desired
features for today's solar observer or researcher... and then some. Operation couldn't be
simpler, just plug it in and a green light indicates when the filter is onband.
The housing operates at 12VDC for field or battery use, included is a 100-240 power supply
with US, European, UK and Australian adapter wall plates, live LCD readout of the filter's
wavelength output (accurate to 0.1Å) and red /blue wing shift buttons that can precisely tune
wavelength up or down for Doppler studies. The unit even includes a serial port for computer
control capability for on-screen display of filter readout. The new Quantum Series body style
is all about ease of operation.... total simplicity

The Quantum SE series are designed for most amateur and some academic applications.
These filters meet the critical DayStar quality control criteria applicable in all visual and some
photographic environments.

Our Quantum PE series is designed for professional research studies and applications in
which precision homogeneity and onband transmitance values across the substrate surface
are required. These filters require additional quality control steps and additional fabrication
and testing time.

All new heated DayStar Filters produced will feature this new housing style at no increase in
cost to the user. Owners may upgrade their existing ATM or University model DayStar filters
to the Quantum series housing. Delivery time on upgrades is currrently 6-10 weeks from
receipt of filter and payment.

All DayStar Hydrogen a filter assemblies need to be used in conjunction with a
lens cover and Energy Rejection Filter. See Energy Rejection Filters for sizing and pricing.
