Solar Analemma. This outstanding image from Alexandra Hart taken over a period of 4 years charts the midday position of the sun in the sky throughout the year. The north–south component of the analemma results from the change in the Sun's declination due to the tilt of Earth's axis of rotation. The east–west component results from the nonuniform rate of change of the Sun's right ascension, governed by combined effects of Earth's axial tilt and orbital eccentricity.

Merry Christmas, Happy New Year and looking forward to a great solar cycle 25!

Piggyback for Lunt LS100?

Post by rbenton » Fri Dec 09, 2016 6:54 pm

I want to piggyback a small camera onto my Lunt LS100. Does anyone know where I can get the proper clamshell ring that would accommodate such a rig? JMI makes some but I don't know if they are the right size. Thanks for any suggestions.
