I expected to find some photos of this occultation.

Mars is the small dot in the upper part of the image, just one minute before occultation.

I have found it excellent for short focal lenghts (up to 50 mm). I do not have an opinion for larger FL.

I also like this lens for astrophotography. It is rectilinear; not fisheye. Here I posted a comparison.

Sunspots were more impressive than eclipse itself. :)

In addition to the ES telescope, I used a Herschelīs wedge (Baader) and a 2X barlow (needed to reach focus).

I had planned an astrophoto session, but I found the sky illuminated by two enormous moving reflectors from a nearby town. Then, I decided to register that light pollution feast.

ISO=800, 240 sec, mounted on an ecuatorial head.

This handsome 1937 Buick Special was owned by my family. I found it in an expo and had chance to take this photo as never before. I used a Pentax K5 and a DA* 16-35mm f/2.8 zoom.
