My primary interest is studying changes in the sky: track comets, observe planets and their changing atmospheres, observe variable stars, transiting exo-planets, observe supernovae or even GRB afterglows.
My secondary interest is imaging. Imaging is a fun activity on its own and very challenging as many techonologies and atmospheric conditions must cooperate.
I tried to determine the rotation of the sun and how it varies depending on the latitude.
By taking long exposure unguided wide field images, one can calculate the rotation period of the earth.
Supernovae decay. I am collecting images of supernovae after their discovery and observe their decay. For example I witnessed a supernova in M51 right after its discovery and saw it decay in the weeks after that.
construction and continued improvement of my observatory. update july 2011: I replaced the tripod by a permanent steel pier, on a concrete base.
I am trying to image all Messier objects.
study of comets, especially nucleus dynamics and tail disconnects
Project 4PM2013: detailed study during 2013 of the four planetary nebulae in the Messier catalogue: M27, M57, M76 and M97.
