Novosibirsk Astrophysical center (“Large Planetarium”)

March 26th, 2012 by Ivan Boldyrev

There was a Planetarium day celebration at Large Planetarium on 24 of March.  This a view from Foucault pendulum tower:

The day was windy and rainy, but about 500 people (as estimated by one of Center’s employee) attended the event.

Novosibirsk Astrophysical Center was open today

February 8th, 2012 by Ivan Boldyrev

“Astophysical” means here “related to both astronomy and physics”, not “related to astrophysics”. This an educational center with planetarium, observatory, meteo station, Foucault pendulum etc.

Observatory has 360mm Ritchey–Chrétien by Astrosib and 200mm APOLAR refractor by NPZ.

See video at Russia 1 channel.

Meeting with amateur astronomers is planned tomorrow, and I am invited too, but cannot participate because of health problems :(

Lunar eclipse of 16th of June 2011

June 16th, 2011 by Ivan Boldyrev

Very sleepy after observing eclipse whole night. I tried to make some photos, by my cheap cam gave me very poor images.

I also observed two passes of ISS during the eclipse. It seems it was first time when I do planned ISS observation :)

As January solar eclipse was at sunset, this eclipse was at “moonset”.

I was observing with binocular and telescope sitting on a sofa on parent’s balcony :)

New old book

April 13th, 2011 by Ivan Boldyrev

Yesterday I received copy of “Observing Earth Satellites” by Desmond King-Hele (1982). It was advised on SeeSat list, and I found a copy affordable for me.

Yesterday event was successful. Andrey’s 75mm refractor displayed nice images of Sun with spots, and my 130mm reflector displayed the rising Moon. The Moon was low-contrast on daylight sky, but children enjoyed it anyway (though some were unable to spot it, but many managed to see lunar maria).
