Sunspot

I managed to capture this sunspot one day with my Orion XT-10 Dobsonian and an Orion Full-Aperture Glass Solar Filter.

 

Blocking 99.999% of incoming sunlight, glass elements are machine-polished and triple-coated with an advanced nickel-chromium stainless steel alloy for a scratch-resistant surface. The filter passes only a fraction of the incoming light, rejecting harmful ultraviolet and infrared radiation.
