the sun on july 3rd 2013

Although imaging the sun is technically the same as imaging the moon and the planets, there is one mayor (and obvious) difference: the use of a solar filter. Because of the immens amount of light that the sun radiates, most of it has to bee filtered to prevent damage to the camera’s of even your own eyes. I use a Thousand Oaks solar filter. This a full apparature filter, placed in front of the telescope.

Most spectacular are the sun spots that move slowly accross the solar surface as the sun rotates in a little more than 24 days. Some sunspots last a couple of days, others can be visible for several weeks
