We often read about such events, which occurred eons back, with great curiosity and astonishment.  But now we have an opportunity to witness one of such significant and rare celestial events which will happen on June 5/6, 2012.

I have clicked away 958 photographs (mostly because I would like to make high-resolution images using image stacking), and going through the entire collection will take a while. In the meantime, I would like to present a sample of the photographs here. Hope you like them.

Summary: What can you do if it is a cloudy day? My attempt at practicing solar photography yesterday evening was a mega disaster! I had only taken 3 to 4 photographs, when the western sky was filled with thick layer of dark clouds (rain came later in the night). So I came back home feeling […]

As the big day is approaching, I think it is important that we have a strategy in place in order to make the best of the situation with whatever constraints we have. Some of us may have the best equipment and some of us may not. Our (gadget) limitations must not stop us from trying what we […]
