3 GREAT EVENTS IN APRIL - TOTAL ECLIPSE OF THE MOON
The day after Mars is at its closest, a Total Lunar Eclipse will occur on the 15th of April.  In most places, the Moon will already be in 
full Eclipse as it rises, during evening twilight. Basically the eclipse's visibility will be greater, and longer, the further east the 
observer is.  Western Australia will miss out on the vast majority of the eclipse. The Total Lunar eclipse will be the first since 2012.

Here are some sites with Total Lunar Eclipse 2014 information:

3 GREAT EVENTS IN APRIL - ANNULAR SOLAR ECLIPSE
The Annular Solar Eclipse of the Sun is on the 29th of April 2014.  All of Australia will have a partial eclipse visible.  For observers 
viewing west of a line drawn from Cairns Queensland, down to Adelaide, South Australia, the eclipse will be in its entirety.  East of this 
line, the Sun will set during the eclipse.

Here's some information on the Annular Solar Eclipse:

TELESCOPES & ASTRONOMY CERTIFIED ECLIPSE GLASSES $4AUD
The Telescopes & Astronomy Eclipse Glasses incorporate our own design which includes a Deep Field Galaxy background and 
Diamond Ring Effect during a Total Solar Eclipse.

During the 2002 Total Solar Eclipse, there was concern over the safety of Eclipse Glasses, since they were not tested and 
certified in Australia, although they were certified everywhere else in the world like England, Germany, and USA etc.  In 
preparation for the 2012 Total Solar Eclipse, and requiring a large amount of work and red tape cutting, we ensured Eclipse 
Glasses were certified prior to the event.

FILTERS FOR PHOTOMETRY
Astronomical Photometry and Spectrometry are now very popular amongst amateur astronomers.  It allows anyone to participate in 
scientific discovery, and can have their data published to provide the astronomical community with valuable information.

Astronomical Photometry is the measurement of electromagnetic radiation given off from an object.  This is called Flux.  Knowing the 
Distance and Flux of an object allows us to work out information like Luminosity, object’s temperature, and the object’s size and other 
physical properties.

Measuring the Flux in small wavelength intervals, allows us to measure other things like what the object is made of, movements, and 
various other properties.  This is called Spectrometry.

A combination of measuring Flux (Photometry) and wavelength (Spectrometry) is called Spectrophotometry.  Photometry being the 
much simpler of the two.

Any high pixel CCD Camera can be used to collect the Flux for measurements.  Some cameras are better than others, depending 
on your budget.  To find out more about Photometry and Spectrometry visit the following websites:

ORION 2" MULTIPLE 4 FILTER WHEEL $170AUD
When it comes to field illumination for visual observing or astrophotography, bigger definitely is better! Enter Orion's new 2" Multiple 
Filter Wheel, which allows convenient switching of up to four 2" filters for astro-imaging. Since many of today's larger format 
monochrome CCD imagers require 2" filters for larger field illumination, this affordable solution provides fast and easy transition 
between multiple filters. 

The versatile Orion 2" Multiple Filter Wheel provides several attachment methods. T-threads on the telescope side allow for a direct 
connection to T-thread equipped focusers. If attaching the filter wheel to a 2" focuser, a 2" thread-on nosepiece is also included which 
allows maximum field illumination to the imaging camera. A removable T-thread ring on the camera side allows for direct attachment to 
imaging cameras. Compatible with all 2" Orion filters. The 2" multiple filter wheel is not equipped for visual use.

This accessory is a must-have for monochrome imagers, who need to take separate exposures through LRGB filters to obtain a color 
composite. Light finger pressure is all you need to rotate the wheel until the selected filter clicks into place. 

The Orion 2" Multiple 4-Filter Wheel also provides a convenient and secure way to store your imaging filters and help protect them from 
dust and dew. Filters can be easily installed or changed by removing the cover with the included hex key. Requires 22mm additional 
focus travel. Weighs just 14oz. One-year limited warranty.

STARLIGHT EXPRESS SXUFW $523AUD
Super-Slim Off-Axis guide head add-on! This useful filter wheel accessory makes accurate, flexure-free guiding easy to achieve. 
The extremely slim assembly screws directly to the wheel face and adds only 13mm to the back focal distance of the wheel.

The USB filter wheel was first introduced in 2009 and adds many new features to a useful imaging accessory. It is unique in that 
it does not require a separate power supply when used with USB control - the high performance DC gear motor runs entirely from the 
USB supply and consumes less than 100mA. It is also capable of operation from a serial input, or from a switched hand controller, 
both of which power the wheel from a small dry battery.

iOPTRON'S SKYTRACKER MOUNT RECEIVES GREAT REVIEWS
The new iOptron SkyTrackerTM camera mount for astrophotography has extra features including an increased payload of 3.5kg
 (7.7 lbs) and an adjustable AZ base. This portable mount makes it easy to take long exposures of the night sky without streaking or 
star trailing.

The SkyTrackerTM is simple to set up. Just attach the unit to a camera tripod. Then slide and lock your digital camera into the 
saddle. Align SkyTrackerTM to the Celestial Pole, using the included dark field illuminated polar scope. Then turn on the 
motor, and it keeps your camera tracking at the same speed the earth rotates! The unique DC servo motor keeps your camera 
in motion to avoid star trails and allows you to take long exposures for beautiful images of the night sky. SkyTrackerTM runs 
on 4 AA batteries for portability at any location.

Generally you'll need the Ball Head ($80AUD) to point in various directions.  If your Tripod has a 1/4" thread (like most), then you 
will also need the 1/4" to 3/8" Adaptor ($6AUD) since the SkyTracker has a 3/8" thread hole.

THE OLDEST STAR
A team of astronomers has discovered the oldest known star in the universe, which formed shortly after the Big Bang 13.7 billion 
years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists 
a clearer idea of what the Universe was like in its infancy.

"This is the first time that we've been able to unambiguously say that we've found the chemical fingerprint of a first star," 
said lead researcher, Dr Stefan Keller of the Australian National University (ANU) Research School of Astronomy and Astrophysics. 
"This is one of the first steps in understanding what those first stars were like. What this star has enabled us to do is record 
the fingerprint of those first stars."

The star was discovered using the ANU SkyMapper telescope at the Siding Spring Observatory, which is searching for ancient stars 
as it conducts a five-year project to produce the first digital map the southern sky.

The ancient star is around 6,000 light years from Earth, which Dr Keller says is relatively close in astronomical terms. It is 
one of the 60 million stars imaged by SkyMapper in its first year.

"The stars we are finding number one in a million," says team member Professor Mike Bessell, who worked with Keller on the 
research. "Finding such needles in a haystack is possible thanks to the ANU SkyMapper telescope that is unique in its ability to 
find stars with low iron from their colour." Dr Keller and Professor Bessell confirmed the discovery using the Magellan telescope 
in Chile.

The composition of the newly discovered star shows it formed in the wake of a primordial star, which had a mass 60 times that of 
our Sun. "To make a star like our Sun, you take the basic ingredients of hydrogen and helium from the Big Bang and add an enormous 
amount of iron -- the equivalent of about 1,000 times the Earth's mass," Dr Keller says.

"To make this ancient star, you need no more than an Australia-sized asteroid of iron and lots of carbon. It's a very different 
recipe that tells us a lot about the nature of the first stars and how they died."

Dr Keller says it was previously thought that primordial stars died in extremely violent explosions which polluted huge volumes 
of space with iron. But the ancient star shows signs of pollution with lighter elements such as carbon and magnesium, and no sign 
of pollution with iron.

"This indicates the primordial star's supernova explosion was of surprisingly low energy. Although sufficient to disintegrate the 
primordial star, almost all of the heavy elements such as iron, were consumed by a black hole that formed at the heart of the 
explosion," he says. The result may resolve a long-standing discrepancy between observations and predictions of the Big Bang.

The discovery was published in a recent edition of the journal Nature as "A single low-energy, iron-poor supernova as the source 
of metals in the star SMSS J031300.36?670839.3." Nature, 2014; DOI: 10.1038/nature12990

SPECTACULAR NEW MARTIAN IMPACT CRATER
A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera 
on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013. Researchers used HiRISE to examine this site because the orbiter's 
Context Camera had revealed a change in appearance here between observations in July 2010 and May 2012, bracketing the 
formation of the crater between those observations.
