ION Filters are affordable Hydrogen Alpha Bandpass Filters with precision control tuning.
Install it on your own telescope*.
*Any DayStar Filter may be used on any aperture telescope with proper energy rejection. ION filters may be used on 150mm aperture or 60mm aperture for almost the same price.
Less expensive UV/IR cut filters may be used in some applications for Energy Rejection on refractors instead of a full aperture front mounted filter. To learn more, contact us on how to safely configure with the UV/IR cut filter. Use of a telescope over 60mm for solar observing without Energy Rejection protection can cause overheating and damage to the telescope.
Easy to own, easy to operate:
DayStar Filters stand-alone Filters may be used on a variety of telescopes.
Filters with 0.8 ångström bandwidths will reveal prominences in high contrast.
Filters with 0.7 ångström bandwidths will reveal prominences in high contrast and occasionally, surface. texture. Prominences are generally larger with .7Å filters than in narrower bandwidths.
Filters with 0.6 ångström bandwidths will reveal some surface contrast as well as prominences. A .6Å filter can be a good compromise for those having a difficult decision.
Filters with 0.5 ångström bandwidths will reveal better surface contrast as well as great prominences.
Filters with 0.4 ångström bandwidths will reveal excellent surface contrast as well as fine chromosphere detail.
Filters with 0.3Å ångström bandwidths will reveal superior surface contrast above any other filter. Views are generally somewhat dimmer. Expect "Pencil-Thin" details on surface and prominence features.
