Descriptions of Images by Mike Bessell, MSSSO

Image Equipment Comment
cenA 40" Bright Radio Galaxy
M31 Nikon Andromeda Galaxy (note HII regions in spiral arms)
ngc6744 40" NGC 6744 a face-on spiral
clouds_20d Hassenblad The Magellanic Clouds our nearest neighbours
Lmc_7 Nikon The Large Magellanic Clouds
Lmc_zoom Nikon Detail of previous image
smc_7 Nikon The Small Magellanic Clouds
smc-zoom Nikon Detail of previous image
30dor_40_BVR 40" The 30 Dor nebula BVR image
30dor_40_BV 40" BV Halpha
30dor.unsharp 40" B [OIII] Halpha
n346_V 40" NGC 346 the brightest O association in the SMC
crux_ha Hassenblad The Pointers, the Southern Cross and the Milky Way around to Carina
Jewel box 40" NGC 4755, the Jewel Box cluster containing kappa Crucis
eta car Nikon The Eta Carina Nebula B [OIII] Halpha
etacar_tr16 40" The centre of the nebula near Eta Carina, the cluster Trumpler 16 and the keyhole nebula
etacar_log-linlin 40" another treatment of the intensities
bo10   Bochum 10 another of the clusters in the Eta Carina Nebula
tr24 40" Trumpler 24 one of the young clusterings in ScoOB1
NGC6188 40" An interesting region of dust and young stars in ScoOB1
pis24   NGC 6357 (Pismis 24) a young star forming cluster containing a bright Wolf Rayet star.
sag-oph Hassenblad A wide-field view of the Milky Way centered on the centre of the the Galaxy. Note the Lagoon and Triffid Nebula which lie in the foreground and are seen against the dust clouds hiding the galactic centre at optical wavelengths.
lagoon_7 Nikon The Lagoon and Triffid nebulae. B [OIII] Halpha
trifid 40" The Trifid Nebula. The changing colours from yellow to red in the lower nebula indicates the ionization gradient, yellow: highest red: lowest. The blue nebula results from mainly blue light reflected by the dust in a cloud more distant from the bright blue stars.
b014 40" Another young star forming cluster near the Trifid and Lagoon Nebulae.
lagoon_7_only Nikon A section of the above Nikon image.
lagoon_40_all 40" The central part of the Lagoon nebula BV halpha
lagoon_haoiii 40" An enlarged porion of the central part of the Lagoon nebula but with the colour table rotated to make a "Turner".
lagoon_sungh 40" Another view of the Lagoon nebula highlighting a bright rim.
eagle.v2 40" The Eagle Nebula NGC 6611, a bright star forming region.
eagle_centre 40" The centre of the Eagle nebula, rotated to the same orientation as the Hubble image.
OriEriEW Hassenblad Mosaiced Hasselblad image of the Orion-Eridanus bubble.
Orion_20 Hassenblad Wide-field image of the greater Orion region. Note Barnard's Loop an extensive HII region surrounding the constellation of Orion and the Orion OB association. the Lambda Orionis bubble is at the top.
orion_st Nikon Between Orion's belt and the great Nebula of Orion. Note the Horsehead Nebula, a dark dust cloud, below the belt and the beautiful whirls of gas streaming away from the Orion nebula.
horsehead 40" The Horsehead Nebula a dark dust cloud.
orion_40 40" The area around the trapezium cluster. B [OIII] Halpha
orion_40_V 40" The area around the trapezium cluster. B V Halpha
Orion_lambda Nikon The Lambda Orionis Bubble. A large Stromgren sphere
Rosette Nikon The Rosette nebula.
n2264n 40" Part of NGC 2264 a young star forming cluster in Monocerotis
n2264w_1.5 40" Part of NGC 2264 a young star forming cluster in Monocerotis
crab_40 40" The Crab supernova remnant. B [OIII] Halpha Note the different green, yellow and red filaments. The green filaments indicate the most energetic shocks.
vela-puppis_20 Hassenblad A wide-field view of the Vela-Puppis association and the Gum Nebula. Note the comet Hale-Bopp lower right on its return South after passing behind the sun.
vela7_low Nikon The Vela Supernova remnant. Same comment as for Crab.
vela_zoom2_o3 Nikon Detail of the Vela SN remnant highlighting some interesting twisted filaments of mainly [OIII] emission.
Hale-Bopp Nikon Hale-Bopp caught as it passed two globular clusters. This image is a V band image with different intensity cuts given a different colour.
Helix 40" The Helix Nebula, a planetary nebula. In this image the green and blue colours have been reversed to give a more pleasing effect.
n330_hst HST A young cluster in the small Magellanic Clouds. The blue colour represents the 164nm Uv band, the green is V and red is Halpha. the pink stars are Be stars, that is, blue stars with strong Halpha emission. The yellow-white stars are A-type supergiants and the orange-red stars are the red-supergiants. All the bright stars in the cluster have masses greater than 12 solar masses and will eventually become type II supernovae like SN1987A.
n2004_hst HST A young cluster in the LMC.
n2100_hst HST A young cluster in the LMC. Study of these young massive clusters will provide details of the evolution of massive stars and the mass function likely to apply to star-burst galaxies.
