Recent Observing and Photography Session

  • Barnard’s Loop – 2018-02-14 - Barnard’s Loop (Sh 2-276) Acquisition 2018-02-14, Denholm Observatory This image captures about half of the structure known as “Barnard’s Loop”. Barnard’s Loop is a huge semi-circular shaped emission nebula in the constellation Orion and part of the even larger molecular hydrogen cloud that covers much of the constellation. The remainder of the “loop” extends down […]
  • Super, Blue, Blood Moon 2018-01-31 - The second full moon of the month is now popularly called a “Blue Moon” (never mind that it got the name through an error – that’s what its now called). On January 1st 2018 we had a full moon (below) and another full moon on January 31st. On January 31st, the moon was again full, […]
  • Heart and Soul Nebula 2018-01-14 - I imaged the Heart and Soul Nebula on 2018-01-14. It was quite cold at -18°C. I haven’t imaged anything in awhile and the cold temperatures usually makes things more difficult. I was concerned that some piece of the work flow wouldn’t work. I did have a lot of trouble framing the field of view. The […]
  • 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 […]
