Here's the home of 2019's 'Image of the Month' pictures. Enjoy!
Image of the Month for January 2019: Comet 46/p Wirtanen
Something a bit different this month, an animation of Comet 46/p Wirtanen taken on the 13 December 2018. Stacked using Deep Sky Stacker. Skywatcher 130P-DS telescope on HEQ5 mount, Canon 45D astro-modded and cooled.
Image of the Month for February 2019: M1, The Crab Nebula
The Crab Nebula, M1, the remains of a supernova recorded as a 'guest star' in 1054 and given its name in 1840 by William Parsons. The object is expanding so fast that differences can be seen in images taken 10 or 20 years apart. Skywatcher 130P-DS telescope on HEQ5 mount, Canon 45D astro-modded and cooled.
Image of the Month for March 2019: The Hickson 44 Galaxy Group
The snappily named and rarely imaged Hickson 44 Galaxy Group is located in the constellation Leo, at the 'back' of the lion's head. It is a small collection of interacting galaxies.
Image of the Month for April 2019: M101, the Pinwheel Galaxy
The Pinwheel Galaxy played an important step in our understanding of galaxies as separate 'island universes' beyond our own Milky Way galaxy, when Lord Rosse was the first person to identify its spiral structure.
Image of the Month for May 2019: NGC4631, the Whale Galaxy
Also known as the Herring Galaxy this is a spiral galaxy, seen almost edge-on with a small companion galaxy. Taken using Skywatcher 130P-DS scope on HEQ-5 mount with a cooled and astro-modded Canon 450D. 63 two-minute exposures.
Image of the Month for June 2019: M13 The Great Globular Cluster in Hercules
M13 is bright enough to be seen as a small fuzzy patch in dark skies, through a medium sized telescope you can start to see the stars that make it up. Taken using Skywatcher 130P-DS scope on HEQ-5 mount with a cooled and astro-modded Canon 450D. A combination of many 30-second exposures taken in 2018 and about 40 120-second exposures taken in May 2019 has helped in resolving stars to the centre of the cluster.
Image of the Month for July 2019: Jupiter
Jupiter is very low down in the sky this year, making imaging a real challenge. In this image from 20 June 2019, the moon Io passes in front of the planet leaving a clear shadow, although the moon itself is a barely visible yellowish patch to the right of the shadow. Below, the Red Spot is unmistakeable, but this 300-year-old storm is shrinking. Will it disappear soon? Taken with a Skywatcher 150PL telescope and ZWO ASI120MC camera and a ZWO Atmospheric Dispersion Corrector, to offset the 'colour smearing' caused by the planet being so low in the sky.
Image of the Month for August 2019: Partial Lunar Eclipse
The partial Lunar Eclipse on 16 July 2019 took place on the fiftieth anniversary of the launch of Apollo 11, so gathering with fellow members of Rosliston Astronomy Group was a great way to mark the occasion. Despite early cloud, satellite imagery from online weather websites showed that we would probably be lucky, and the moon appeared from behind cloud about twenty minutes after it rose. We were able to view about an hour and a half of the spectacle, as scattered cloud came and went, before another big bank of cloud moved across, so we saw the point of deepest eclipse. This image is from fairly early on, taken with a Canon D1000 mounted on a Celestron C90 Mak, and stacked from about fifteen images that were clear of cloud.
