Jupiter

Clear sky but low seeing which in very poor results.

Setting : ASI 224MC with TAL200K, Barlow x2 and ADC. In total 3000 frames are stacked using AutoStakkert! and final editing using CS4 and DeNoise AI.

My picture on National TV (again)

My picture, which I took this morning, of the port of Oostende was broadcasted on the National TV. During "Het Weer", the daily weather forecast from channel 1, my picture was presented by Frank Deboosere.

Black Holes and Gravitanional microlensing by Prof Lukasz Wyrzykowski

Selfie with Prof. Lukasz Wyrzykowski

Last saturday, October 2nd, Prof. Lukasz Wyrzykowski from the Astronomical Observatory of the University of Warsaw, gave a lecture on "How to find black holes with gravitational microlensing". The lecture was given as part of the JVS/VVS astronomical weekend at Oostend (Belgium).

ADC set up

How to set up an ADC or Atmospheric Dispersion Corrector? Currently I'm using my ADC only for planet astrophotography and have experience with Mars, Jupiter and Saturn.

When using my TAL200K, the ADC connected to my camera (ASI224MC) and screwed after the barlow and eyepiece holder of 1.25"- see picture below.

Left to right: ASI224MC, ADC, Barlow, 1.25inch eyepiece holder

During operation I'm adjusting the ADC visualy but recently I was told that adjustment can be done using FireCapture, SharpCap aswell as ASICap (ASIStudio). This will be tested next time when I'm out for a planet astrophotography session. 

My picture on National TV

My picture, which I took this morning, of a bright halo around the Sun was broadcasted on the National TV. During "Het Weer", the daily weather forecast from channel 1, my picture was presented by Sabine Hagedoren.

Total Solar Irradiance 1361W/m2 from SORCE

Final (V.19) TSI data products from the SORCE/TIM (SOlar Radiation and Climate Experiment/Total Irradiance Monitor) have been released (available from lasp.colorado.edu/home/sorce/data/tsi-data/ and disc.gsfc.nasa.gov/datasets?page=1&keywords=sorce), completing the instrument’s 17-year measurement record of the net radiant energy incident at the Earth and powering the Earth’s climate system. The many innovations in this new instrument improved the accuracy of the TSI measurement record and propagated that to other TSI instruments, leading to the establishment of the now-accepted TSI value of 1361 Wm−2. Other science results include the first detection of a solar flare in TSI and the measurements of two Venus and four Mercury planetary transits across the solar disk. The Mercury transits are indicative of expected signals of an Earth-like exoplanet transiting a Sun-like star.
