(Bird of Paradise)
 
 
  Apus is a tiny insignificant southern constellation that supposedly resembles a bird of paradise, the Apus Indica. There are also no spectacular deep sky objects.
   
 
   
  NGC 6101:
 

Comprised of faint stars, this globular cluster is north of the star, Gamma Apodis.

               
  IC 4633:
 

An incongruous mix, this is a faint galaxy with even fainter greenish background nebulosity. This nebulosity is known as the Integrated Flux Nebula. This is a special type of nebula that glows by reflecting all the collective light of the Milky Way. Examples of other galaxies that share a line of sight with integrated flux nebulae are M81 in Ursa Major and NGC 1 and 2 in Pegasus.
The nebula near M81 is informally referred to as the Angel Nebula and is formally referred to as MW3. The MW stands for 'Mandel-Williamson' and is a catalogue of the integrated flux nebulae. Integrated flux nebulae are referred to as 'galactic cirrus' by some astronomers.

Amateur astronomer Steve Mandel, rediscovered these huge clouds after noticing one in an astroimage he had taken. After consulting with specialists including Adolf Witt and David Malin, it was evident that these integrated flux nebulae had been previously detected on photographic plates acquired in the 1960's but were not studied due to being thought of as generic dust clouds that blotted the extragalactic view.

Since no previous effort had been undertaken to catalogue and study them, Steve Mandel took direct action into his own hands and started cataloguing each one he encountered. Many eminent astrophotographers and researchers collaborated with him and helped him out by imaging some of the nebulae. Currently he is working with a research group and is regularly making discoveries that prove amateurs are capable of valid scientific research.

The 'IC' stands for Index Catalogue and is a catalogue of 5386 different deep sky objects. It is a supplemental catalogue to the more acclaimed New General Catalogue (NGC for short), which contains 7840 different objects. Both catalogues were the result of vigorous and detailed observations by a man called John L.E. Dreyer in 1888 and afterwards.
