ngc 253 John Herschel in South Africa ( NGC 253, Sculptor Galaxy )
MikeODay posted a blog entry in The Sculptor Galaxy - NGC 253
Sir John Herschel at the Cape of Good Hope Having spent the years 1825 to 1833 cataloguing the double stars, nebulae and clusters of stars visible from Slough, in the south of England, John Herschel, together with his family and telescopes, set sail from Portsmouth on the 13th of November 1833 bound for Cape Town. As detailed below, in an extract from his book, the family enjoyed a pleasant and uneventful voyage and arrived some 5 months later at Table Bay with all family and instruments in good condition. Reading on however, one might very well think that it might not have ended so-

Observations of the Sculptor Galaxy ( NGC 253 ) by William and John Herschel ......... Part 2. Observations of "Caroline's Galaxy" by Sir John Herschel, 1830's Sir John Herschel, the only child of Mary Baldwin and Sir William Herschel, was born in 1792 when his father was in middle age and already famous as one of world's leading astronomers. Having excelled in school, and no doubt inspired by his famous elders, John Herschel decided upon a career as a 'man of science' and set out to pursue a wide range of interests; with one particular focus being a continuation of the

Observations of the Sculptor Galaxy ( NGC 253 ) by William and John Herschel The very large and bright 'nebula' discovered by Caroline Herschel in 1783, that we now know as the Sculptor Galaxy, was observed a number of times by her 'dear brother' Sir William Herschel and by her 'beloved nephew' Sir John Herschel, Baronet. Some of these observations were recorded and published in the Philosophical Transactions of the Royal Society and, with respect to those by Sir John in South Africa, in the book of Astronomical Observations at the Cape of Good Hope. .........

21st April: Re-processed to better show the colour of the fainter stars ... ....... Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500 light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa. This HDR image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ). Total exposure time was around 5 hours. A Clus

Update: 3rd June Re-processed to remove slight magenta tint caused by the non-uniform removal of light pollution by the DBE process ( it was being fooled by the very bright image centre ).

Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades open star cluster ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) Image details

The Jewel Box ( NGC 4755 ) is an open cluster of mostly hot young blue-white stars that appears to the unaided eye as a bright 4th magnitude star close to the Southern Cross. Only visible from southern latitudes, the Jewel Box was first recorded by Nicolas Louis de Lacaille during his visit to South Africa in 1751 and was later described by Sir John Herschel as "a casket of variously coloured precious stones" - hence the name "Jewel Box".

The Southern Beehive Cluster ( NGC 2516 ) in the constellation Carina re-processed ( improved colour balance, more colour in the smaller stars and lower saturation overall ): previous version: ( click on image to see larger ) Because of its similarity M44, NGC 2516, which is only visible from lower latitudes, has become known as the Southern Beehive Cluster. At a distance of around 1300 light years, NGC 2516 is relatively close to us and resides in the same spiral arm of the Milkyway as we do. Containing around 100 stars, with a number o

It looks like I may be spending a week on a farm in South Africa in mid to late June. The farm also operates as a Cheetah sanctuary and I will be volunteering as a feeder, walker and mucker outer of various big cats etc. The evenings are my own and the skies get pretty damn dark I have a set of 10 X 21 bins but am hoping to borrow some a little more powerful. What should I be trying to find in the skies? Cheers.

The Southern Beehive Cluster ( NGC 2516 ) in the constellation Carina - by Mike O'Day ( 500px.com/MikeODay ). Because of its similarity to the “The Beehive Cluster” ( catalogued as M44 by Messier ), NGC 2516, which is only visible from lower latitudes, has become known as the “Southern Beehive Cluster”. At a distance of around 1300 light years, NGC 2516 is relatively close to us and resides in the same spiral arm of the Milkyway as we do. Containing around 100 stars, with a number of them in the magnitude 5 to 6 range, NGC 2516 has an apparent magnitude of 3.8 and is visible to the

The Southern Pinwheel Galaxy ( Messier 83, NGC 5236 ) in the constellation Hydra. Additional sub-images added ( 9 x 3 min @ ISO 200, no filter ) and colour balance tweaked to remove slight yellow/green tinge. The lower ISO and removal of the LP pollution filter has made it easier to bring out the subtle colours in the stars. ( click on image to see fuill size ) Messier 83 is a relatively large and bright spiral galaxy visible from southern and mid latitudes. Clearly visible is the central bar with its bright central bulge as well

The Southern Pinwheel Galaxy ( Messier 83, NGC 5236 ) in the constellation Hydra. ( click on image to see fuill size ) Messier 83 is a relatively large and bright spiral galaxy visible from southern and mid latitudes. Clearly visible is the central bar with its bright central bulge as well as multiple dark dust lanes and areas of nebulosity in the sweeping arms. At a distance of 15 Million light years, the Southern Pinwheel Galaxy, whilst close in astronomical terms, is too far away and hence way too small for my backyard telescope to resolve individual sta
