NGC 2683<\/figcaption><\/figure>\n

The first, NGC2683, is an edge – on spiral galaxy in the constellation Lynx.\u00a0 On this occasion, stars as faint as magnitude 13.3 were seen.<\/p>\n

NGC2683 is magnitude 9.6, angular dimensions 9.3′ x 2.2′,\u00a0 and is considered to be between 16 and 20 million light years from Earth.<\/p>\n

M2<\/figcaption><\/figure>\n

This drawing is of the globular cluster M2, in the constellation Aquarius.\u00a0 At 150x,\u00a0 no individual stars in the cluster were resolved.<\/p>\n

M36<\/figcaption><\/figure>\n

Michael’s third drawing is the open cluster M36, in the constellation Auriga.<\/p>\n

He noted\u00a0that there were a large number of magnitude 9 – 10 stars in the centre, extending along the spidery arms, and that stars down magnitude 11.5 were visible;\u00a0the main cluster being elongated N – S.<\/p>\n

The final drawing is of galaxy M82, in the constellation of Ursa Major,\u00a0 and shows the recent supernova:<\/p>\n

Dale Holt, using a 505mm (20″)\u00a0 reflector and Watec 120n+ video camera, drew galaxy NGC3081, in the constellation Hydra.<\/strong><\/p>\n

NGC 3081<\/figcaption><\/figure>\n

 <\/p>\n

This is a Seyfert (active) galaxy about 100 million light years away, and is considered to be one of the best examples of a resonance ring barred spiral known.<\/p>\n

Visually, Dale likened it to a planetary nebula with a bright, stellar – illuminated core, with a fainter outer shell of expanding debris.<\/p>\n

NGC 2392<\/figcaption><\/figure>\n

– this time at f10 ( the February 2014 image was taken at f6.3), with the intention of capturing more structural detail.\u00a0 Small, bright planetary nebulae may respond well to a higher f ratio and thus higher magnification, when employing a sensitive digital camera.\u00a0 This image was taken with a Meade DSI II Pro mono camera, using Astronomik RGB filters to produce a colour image.<\/p>\n
