Solar filter for 200 mm telescopes

Objective solar filter - with Baader solar filter foil, for 250 mm telescopes
Solar filters are mounted in front of the telescope and reduce solar radiation to safe levels and suitable for direct observation of the sun.

Solar filters are equipped with the safe and renowned AstroSolar filter foil by Baader Planetarium. The filter foil's quality is superior to most glass solar filters making the image quality sharper and more contrasty than standard mylar and polymer foils. The sun is depicted in neutral white color and with a resolution that's only limited by the seeing conditions and the physical characteristics of your telescope.

Safety:
Celestron Solar Filters with Baader AstroSolar foil provide full protection agains harmful UV and infrared rays. UV is completely absorbed, rated as ND-5, which means that the film allows passage of 1/100.000 percentage of visible light (.001%) and thermal radiation is reflected by 99.999%. The amount of light that enters the telescope is equal to the brightness of the moon.
Glass filters can break or suffer fine spots with high transmission letting UV and IR pass because they are mostly coated at only one side. The Baader foil is coated on both sides offering double security. And what is more, the foil offers some flexibility and high resistance against ripping. Breaking is absolutely impossible. The cell is very lightweight and made of weather proof ABS plastic. As long as the proper size is chosen, optimal fit to the telescope is guaranteed.
