Although the August 21st eclipse happened about 6 weeks ago, I realized it would take me a long time to edit all the photos I took during my trip. I had over 2000 individual shots of the eclipse alone, taking a single (1/4000 s) shot every 10 seconds, at ISO 100, with my telescope coming out at around f/6. I’ve done a lot of time-lapse photography before, so I thought it would be a routine shot, but I was wrong. Eclipses are much tougher to edit in terms of a time-lapse. But first, the end result of my 10 hours...
Last year after getting a Canon DSLR camera, I spent as much time as I could doing some basic astrophotography. I took photos of stars, planets, the Moon, and even did some star trails. One thing I quickly realized is that there are limitations if you don’t have a tracking mount or a telescope adaptor. The tracking gives you a method for taking longer exposures, and the telescope adaptor as expected gives you the ability to zoom in on distant objects. Even with these temporary limitations (I hope to invest in them someday) there are still a lot of options...
The Past: Mars has water, and it used to have a lot more. If modern Mars had the ocean it once had, it would evaporate off into space quickly because there is no heavy atmosphere to help keep it pressurized and in liquid form. Mars would have had a thicker atmosphere in addition to it’s magnetic field in order to keep all that water in one place. So where did the atmosphere go? And if there was such a thick atmosphere, how does it account for the fingerprint of excess Carbon-13 and a lack of Carbon-12 found on the red planet...
