    S5 0014+81

    From the album: Misc1

    S5 0014+81 is a distant, compact, hyperluminous, broad-absorption line quasar or blazar located near the constellation Cepheus. S5 0014+81 is one of the most luminous quasars known, with a total luminosity of over 10^41 watts, equal to an absolute bolometric magnitude of -31.5. If this quasar were at a distance of 280 light-years from Earth, it would give as much energy per square meter as the Sun despite being 18 million times more distant. In 2009, a team of astronomers using the Swift Spacecraft used the luminosity output of S5 0014+81 to measure the mass of the central black hole. They found that the central black hole of S5 0014+81 is actually 10,000 times more massive than the black hole at the center of our galaxy. The Schwarzschild radius of this black hole is 118.35 billion kilometers, an external horizon showing a diameter of 236.7 billion kilometers, 1,600 astronomical units, or 37.4 times the diameter of Pluto's orbit. S5 0014+81, which is located some 12.1 billion light-years distant, is thought to be the largest supermassive blackhole known.
  3. Good work. Try S5 0014+81.

  6. Keep imaging these asteroids chaps.
  7. Hi Doug. Slight correction: 2010 TK is an Apollo type near-Earth asteroid. 2010 TK7 is an Aten type near-Earth asteroid, and Earth trojan
  8. Good work Runcorn. I look forward to seeing your observations. Incidentally, one of my observatories is Z48.
  9. Astrometrica is the standard astrometry software used. I'm sure I will notice if a new obs code appears on the MPC. Good luck.
  10. As long as your residuals are good you ought to get an observatory code. Did you recieve an autoack? What objects did you observe? And what did you use for astrometric reduction?
  11. You could actually just have: TEL 0.15-m f/10 reflector, for example.
  12. Hello Gary, Example: TEL 0.15-m f/10 reflector + Photographic. In addition, column 15 of the observation lines (usually "C" for "CCD") must be left empty.
  13. Welcome D-VDER . A Londoner too

    Hey all

    West Lutton or Sledmere...
  16. Look in c /windows/system32/drivers/ for a driver called ser2pl64.sys (I have the 64bit version) If it is not there, download that file and place it in the folder.

  19. Yes, this is what happens. Did you look for the file I suggested? This will resolve the port issue. Also, run Toolbox from EQMod instead of EQascom.
