Recent Observing and Photography Session

  • M31 – Andromeda with Hubble’s Cepheid Variable V1 – 2017-01-15 - The image below is a closeup of the Andromeda galaxy core. The area photographed includes the Cepheid variable star – M31_V1 – that Hubble used to calculate the first reliable distance to the “Andromeda Nebula”. His result proved conclusively that “nebula” were distant objects that were not part of the Milky Way. The wide field view of Andromeda […]
  • Moon in Haze – 2016-10-16 - I took this picture of the moon on a hazy, slightly foggy evening in October when the moon was one day past full. Taking a picture of the moon on a hazy evening proved to be quite challenging. To the naked eye, the moon looked much as it does on a clear night, albeit with […]
  • Vega and the Constellation Lyra – 2015-10-30 - The bright star Vega at magnitude 0.03 is the 5th brightest star in the sky and the third brightest star visible from the 45th parallel (Ottawa). Sirius at magnitude -1.46 is the brightest star in the sky and Arcturus magnitude -0.05 is the second brightest in the north. Although the yellow-orange star Arcturus is only […]
  • Lunar Eclipse – 2015-09-27 - The weather reports of the preceding days and even the day of the eclipse predicted clear skies. So i planned a photography project to create a time lapse sequence covering the entire event from penumbra advance, through total eclipse and then the receding shadow. As it turns out, the clouds moved in about the time […]
  • Hornets -2015-09-08 - I opened up the observatory this evening for a quick test of some upgraded software and a mini-guider using a finder scope. I did a quick scan of the roof before opening it to check for bugs – wasp and hornets in particular. I didn’t find anything untoward so i opened up the roof and […]
  • Abell 1656 – Coma Cluster – 2015-05-18 - Coma Cluster (Abell 1656) Imaged 2015-05-18 The Coma Cluster is a large cluster of galaxies that contains over 1,000 identified galaxies. Th image below shows a just a few hundred. The magnitudes of the ten brightest galaxies are between 12–14. The two largest galaxies at the centre are supergiant elliptical galaxies: NGC 4874 and NGC […]
  • M96 Group in Leo – 2015-04-14 - M96 Group in Leo (the Leo I Group) acquired 2015-04-14 The image below shows 5 of the 8 brightest galaxies in the M96 group. There are estimated to be as many as 24 galaxies in the group, all of which are in the same general vicinity and gravitationally bound to each other. From left to right: NGC […]
  • Eskimo Nebula – 2015-03-23 - Eskimo (Clown) Nebula (NGC 2392, Caldwell 39) Taken 2015-03-23, 21:00 to 23:30edt This is a planetary nebula called the Eskimo Nebula or sometimes Clown Face Nebula. Planetary nebulas get their name because they appeared to early telescope observers like giant planets. They are actually an expanding shell of ionized gas ejected from a catastrophic event […]
  • Venus and Mercury – 2015-05-06 - Mercury Mercury was at its greatest elongation for 2015 om May 6th at 21deg, so i decided to try to capture an image of it. Being low in the sky it’s hard to get a clear view through the murky unstable surface air. So i decided to capture the image just after sunset at 20:19edt […]
  • Micro Moon – 2015-03-05 - To complement the “Super” moon of September 9th, 2014, the moon was at it smallest for 2015 on March 5th. The conditions were almost just as good as in September 2014, so i managed to capture a view of the apogee full moon (furthest away) that was almost indistinguishable from the Super moon expect that […]
