My specialization is drawing planets and especially comets (or other objects, which are visible by middle-sized telescopes without CCD camera). I also make visual observations of comets (estimating of brightness of comets and estimating of diameter of coma especially). Results (in ICQ format) of these observations I send to SMPH (- in english Society for interplanetary material), from where my observations are sent to International Comet Quarterly (ICQ). Here is explanation of observation report, which you can see with every drawing.
I started to observe the sky around year 1997 by 8x30 binoculars from my granpa. After entry at Pardubice observatory in 1998 I enjoyed many phenomena and objects by local big telescopes - Cassegrainian 420/5600 mm and refractor 135/2200 mm. In 1999 my parents bought me my the first own astronomical telescope - Newtonian 76/700 mm on paralactic mount.
Thi big break in my life came in 2003, when I was given by Dobsonian 250/1250 mm made by Jiri Drbohlav. In that time opened to me the wide world of faint objects and amazing sceneries of special astronomical events. I had enjoyed this telescope for six years, to 2007. In the year I got a driving licence and I found out the telescope is too big to take it by my small car. Meantime, Pardubice observatory upgraded the main telescope to Cassegrainian 450/6750 mm.
Jiri Drbohlav jr. in that time started to construct new type of truss designed Dobsonian telescopes. After years of decisions I finally let him construct me Dobsonian 350/1750 mm of this type. I observe with it now. I also have two better binoculars 10x50 and 11x70.
