A mosaic of the region around the centre of the Milky Way in Sagittarius and Scorpius. The field takes in the Milky Way from the Cat's Paw Nebula at bottom edge to the Eagle Nebula at top left. In between from top to bottom are the Swan Nebula (M17), the Small Sagittarius Starcloud (M24), the Trifid and Lagoon Nebulas (M20 and M8) and the open clusters M6 and M7. The prominent dark nebula at right is the large Pipe Nebula (B78) with the small Snake Nebula (B72) above it. The whole complex is visible to the naked eye as the Dark Horse.

A mosaic of the region around the Small Sagittarius Starcloud and Dark Horse dark nebula complex. The field takes in the Milky Way from the Lagoon Nebula at bottom to the Eagle Nebula at top left. In between from top to bottom are the Swan Nebula (M17), and the Small Sagittarius Starcloud (M24). Flanking the bright M24 starcloud are the large open clusters M23 (right) and M25 (left). At bottom left is the M22 globular star cluster. The prominent dark nebula at right is the large Pipe Nebula (B78) with the small Snake Nebula (B72) above it. The whole complex is visible to the naked eye as the Dark Horse.

Splendours of the southern Milky Way from Vela (at top right) to Centaurus (at bottom left), including the Carina Nebula, Crux and Coal Sack, and Alpha and Beta Centauri. A part of the huge Gum Nebula is at far right. The False Cross is at right, with the large cluster NGC 2516, the Diamond Cluster, below it. The globular cluster Omega Centauri is at upper left.

All of Scorpius, plus parts of Lupus and Ara regions of the southern Milky Way. This area was directly overhead when I took this at about 4:30 am local time on April 6, 2014 from near Coonabarabran, Australia. The head of Scorpius is at top his tail at bottom though you could turn this image any direction and it would be correct as seen in the sky at this latitude, depending on the time of night. But in portrait mode like this north is at top. Along the Milky Way are numerous nebulas, including the False Comet area, the Cat's Paw area, and the colourful nebulas around Antares at top. The dark Pipe Nebula is at left of frame.

The centre of the galaxy area of the Milky Way toward Sagittarius and Scorpius, with the Sagittarius Starcloud right of centre, and the Lagoon Nebula (M8) left of centre. The Cat's Paw Nebula (NGC 6334) in Scorpius is at upper right, the Swan Nebula (M17) and Eagle Nebula (M16) are at lower left. To the right of them is the Small Sagittarius Starcloud (M24). At the very top is the Snake Nebula (B72). The main mass of dark nebula is the Pipe Nebula (B78). Above M24 at left is the open cluster M23 while below the M24 star cloud is the cluster M25. The globular M22 is at the bottom edge. At right of frame are the open clusters M6 (in the dark area of the Milky Way) and M7 (in the bright starcloud).

A horizon-to-zenith panorama of the winter consellations on a March evening as they set into the southwest. Orion is at bottom centre, with his Belt pointing down to Canis Major and up to Taurus. Gemini and Auriga are at top, in this case near the zenith overhead. The bright star clusters, M44, the Beehive, (at left) and M45, the Pleiades, (at right) flank the Milky Way. M45 is embedded in the Zodiacal Light. The star clusters M35 in Gemini and M41 in Canis Major are also visible as diffuse spots, as are several other star clusters. A couple of satellite trails are visible.

The summer Milky Way overhead and through the Summer Triangle stars in July, looking up through trees in Banff National Park at Herbert Lake. Deneb is at top left, Vega at top right, and Altair is at bottom. The bright Cygnus star cloud is obvious. As are the dark lanes in the Milky Way, including the Funnel Nebula at top, aka Le Gentil 3.

This is the central area of Cygnus and its bright Milky Way starcloud surrounded by red nebulosity. At left is the star Sadr (gamma Cygni) with the complex of nebulosity catalogued as IC 1318. At centre is the distinct Crescent Nebula, NGC 6888, a expanding nebula created by winds from a hot Wolf-Rayet star. At bottom left is the star cluster Messier 29, though looking a little lost in the rich starfields here. At top is the cluster IC 1311, looking more obvious than M29 but not observed visually and included in the NGC catalog. Odd. At far right are the large and loose star clusters NGC 6883 and NGC 6871, the latter an obvious binocular sight. To the left of Sadr is the small cluster NGC 6910. The dark nebulas B145 and LDN 862 are at right. The small emission nebula at bottom is Sharpless 2-104.
