DayStar Hydrogen Alpha T-Scanner Filters (With prices starting at $1625)
DayStar
Sub-angstrom Hydrogen Alpha filtters are rear-mounted filter assemblies
designed to operate at the eyepiece position of the telescope. This
allows greater adaptability to different telescope configurations and
for larger telescope apertures. Rear-mounted filter systems allow for
high resolution observing and imaging at focal lengths frequently in
excess of 1000mm. Our filters are classified by bandwidth, not
aperture. Narrower bandwidth filters reduce off-band transmitence and
increase contrast. The smaller the bandwidth, the higher the contrast
between on and off/band light.
DayStar T-Scanner Filters require NO POWER to operate properly.
DayStar T-Scanner Filters are very inexpensively priced.
DayStar T-Scanners can be mounted on almost any telescope from 60mm to 600mm.
DayStar T-Scanners can be used full aperture* on most telescopes.
DayStar T-Scanner Filters can show a choice of the full disk or high resolution.
DayStar T-Scanners are robust. Shipping by ground service does NOT void our 10 year warranty
The T-Scanner model (like all non-heated narrow bandpass solar filters) is
designed to operate best at an ambient 75 degree temperature with a
tilt knob adjustment to accomodate a shift of approximately 20 degrees
F. Observers in climates likely to vary greatly who want to use their
filters year-round without temperature concerns should consider the Quantum Series as an affordable option.
Filters with 0.8 ångström bandwidths will reveal prominences in high contrast.
0.7 ångström
$2200.00
Filters with 0.7 ångström bandwidths will reveal prominences in high contrast and occasionally, surface texture.
0.6 ångström
$3100.00
Filters with 0.6 ångström bandwidths will reveal some surface contrast as well as prominences.
0.5 ångström
$4000.00
Filters with 0.5 ångström bandwidths will reveal better surface contrast as well as great prominences.
0.4 ångström
$5200.00
Filters with 0.4 ångström bandwidths will reveal excellent surface contrast as well as fine chromosphere detail.
0.3 ångström
$6350.00
All DayStar Hydrogen a filter assemblies need to be used in conjunction with a Rejection Filter.

Energy Rejection FiltersEnergy Rejection Filters reduce the heat load on your filter assembly by absorbing or reflecting UV and/or I light and transmitting light in the desired visual spectrum. These filters are sometimes Red or Yellow glass, or dielectric IR and UV, but pass light in the desired visual spectrum. The ERF can also serve as an aperture mask to accomplish a straight angle of incidence for light entering the filter...
