NGC7293 Helix (Planetary) Nebula iTelescope Data

This Planetary (Emission) Nebula was crreated when the white dwarf star (centre) in it's former phase as a Red Giant Star underwent core collapse when it ran out of fuel to power it's nuclear fusion.   Very large red dwarfs that undergo core collapse turn into neutron stars or black holes but this particular example had only enough mass to compress the remaining components to a densly packed object consisting of carbon, oxygen and helium all held together with electron degeneracy which counters and stops the inward gravitional push.  It's the same force that holds our bodies together without which the atmospheric pressure and gravitional pull of earth would just squash us.  During the process the outer layers are ejected into space to form the surrounding nebula.  While it's the final chapter of a dead star it is also a picturesque reminder of the laws of physics that makes our existence possible in this universe.

I have rediscovered Astro Pixel Processor after about a year ago when I was exerimenting with a couple of 30 day free trials for this, Astro Pixel Processor(APP), and Pix Insight.   At the time I opted to go for Pix Insight but have found it inaccessable especially without hours and hours spare to get in and learn how to use it.  I still intend to develop skill with Pix Insight but in the meantime with the advent of free monthly downloads of image sets and a series of post processing online tutorials using APP at iTelescope I have revisted this software and feel like I have made some small progress.

 

Omega Centauri and 47 Tucanae 19th March and 1st September 2021

47 Tucanae

Omega Centauri and 47 Tucanae (above) Globular Clusters are the brightest examples of such in the southern hemispere skies and are amongst the most ancient relics (cosmically speaking) that can be easily located and observed with the naked eye and small to larger aperture backyard telescopes.  On average globular clusters are aged by their coolest white dwarf stars to around 12 billion years old.  Incidentally at relatively younger age of around 8 billion years our own sun will itself become a white dwarf.   Shedding it's outer layer it will leave a dense but hot core of materials behind including what remants of our Earth are left assuming it hasn't been consumed by the previous and much larger red giant phase of our sun.

Omega Centuari has a  notably bright spherical ball like appearance and contains, as it's appearance suggests, millions of stars. Originally and mistakenly it was named for being the 24th cataloged star in the constellation of Centaurus (The Centaur).  In this same constellation the brightest star,  so named 'Alpha' Centuari (one of the two pointers to the Southern Cross), consists of a triple star system (the closest to our solar system) , a mere(cosmically speaking) and aproximate 4 light years distant or in every day terms 40 trillion kilometres hence.  Omega Centauri sits 17000 light years away above the Sagittarius Arm of the Milky Way Galaxy.  It is a wopping 272 light years wide a similar distance from Earth to Beta Centauri (The other Pointer Star).  

Like Omega Centauri, 47 Tucanae, in past centuries, it was thought to be a star and was cataloged 47th in the constellation of Tucanae (The Toucan).  Its lies 13500 light years away below the Sagittarius Arm of the Milky Way Galaxy.  It is measured at a smaller 120 lightyears in width.   In comparison to Omega Centauri, 47 Tucanae has a notably denser central core but petering out into the blackness of space with a less dense appearance on the periphery. 

You can make sense of the relative positions in the sky of these two globular clusters, one above and one below the  plain of the galaxy when we see the southern portion of the Milky Way, containing the Southern Cross and many other stars, nebulae etc, intersecting between the two objects.
