The Celestron PowerSeeker Accessory Kit is a great way to expand the enjoyment of your telescope. Inside the plastic, foam-lined carry case you’ll find these accessories:

• 15mm Kellner Eyepiece - 1.25”
• 9mm Kellner Eyepiece - 1.25”
• #80A Blue Filter - 1.25”
• #25 Red Filter - 1.25”
• Moon Filter - 1.25”
• Microfiber Cleaning Cloth

Eyepieces - The 15mm and 9mm eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 9mm provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

Filters - Coloured filters can be used to bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

• The #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the color shift.
• The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It’s also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.
• The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it helps you see which phase she’s in.

Cleaning Cloth & Case - Keep the microfiber cleaning cloth stashed in your PowerSeeker Accessory Kit case so that it will always be handy. It’s better to use a microfiber cloth on your optics than wipes or tissue, as it will not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you’ll keep them looking and performing like new.

Star Analyser 200

Since its launch in 2005, the Star Analyser 100 has introduced thousands of amateur astronomers worldwide to the fascinating field of spectroscopy. Over this period, the equipment used by amateurs has evolved with larger aperture telescopes, bigger camera sensors and close coupled filter wheels becoming more common. The Star Analyser 200 model has been developed with these users in mind.

Using the same Paton Hawksley high efficiency blazed diffraction grating technology as the SA100, but with double the line density. The SA200 is designed for applications where it is difficult to achieve the optimum spacing needed for the SA100. The SA200 gives the same length of spectrum at half the spacing compared with the SA100.

ZWO ASI6781MC

ZWO ASI678MC adopts Sony's Latest generation sensor IMX678 with excellent near-infrared response. With the advantages of Large full well capacity, high dynamic range and low readout noise, this camera has been tested and found to have perfect performance in planetary imaging, solar and lunar imaging.

Clear in low light

Thanks to the back-illuminated sensor structure and advanced pixel techno[ogy, the camera has very low readout noise and an ultra-high sensitivity. Especially in Low light conditions, the camera performs very well and is able to capture very clear images of celestial objects.

STARVIS 2

ZWO ASI678MC can be regarded as an upgrade of ASI178MC. It adopts the latest SONY IMX678 sensor with advanced STARVIS 2 technology. Compared to ASI178MC, this camera features zero amp glow, lower readout noise and higher sensitivity. The dark current noise is greatly decreased; the performance of near-infrared is greatly improved.

USB 3.0 & 256M DDR3 Memory

The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission. Under Long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.

Upgraded Model

The ZWO ASI678MC is an upgraded product of the ASI178MC. Compared to the ASI178MC, the ASI678MC has lower read noise, lower dark noise, and no amp glow.

No Amp Glow

ZWO ASI678MC exhibits zero amp glow, no matter how long the exposure and how high the gain value is. Since it is implemented directly at the hardware level, it does not require software control.

HCG Mode

The camera has a built-in I-ICG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at [ow gain. When the gain is 182, the I-ICG mode is automatically turned on. The readout noise is as low as 0.8e, and the dynamic range can still reach a level close to 12bit.

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and tower readout noise are necessary to improve the image signal-to-noise ratio.

Dark Current Noise

ASI678MC has much lower dark current noises than ASI178, bringing it has better image signal-to-noise ratios. If we compare the darks frames captured with these two cameras, it can be easily found that the frame from ASI678 has much Less noise and rooks much smoother.

ZEISS Terra® ED binoculars are robust, reliable and easy to use. Their state-of-the-art and sleek design makes them not only light but comfortably compact. The highest optical precision and the hydrophobic multicoating guarantee brilliant images down to the very last detail. The Terra ED binoculars are waterproof and nitrogen-filled, making them rough and ready. Terra ED binoculars are excellent value for money, making them the perfect entry into the world of ZEISS.

A bright image, outstanding resolution of details and comfortable viewing characteristics. In combination with optimum ease of handling, these perfectly describe the outstanding properties of the Terra ED 42.

High quality, fast refractors have a lot going for them when it comes to astrophotography but they come with a downside - field curvature. This is where the image comes to sharp focus on a curved surface. The problem is that the sensors in cameras are flat. The larger the sensor - like those used in cameras with APS-C sized or larger sensors or DSLR cameras - the more effect is noticed.

A field flattener brings the image to focus on a flat surface, like your camera's sensor. At the same time, the basic optical performance of your telescope remains the same.

You will need 55mm of backfocus.

The Bintel T-thread Spacer Ring Kit (sold separately) is recommended to achieve proper distance for use with CMOS imagers.

Use with a DSLR only requires a T-ring for the camera (T-ring sold separately).

Tele Vue Ethos 21mm Specifications

Introduced at the 2007 Northeast Astronomy Forum, Tele Vue once again broadened the amateur astronomer's perspective on the universe with: 100° of pure Tele Vue quality. The field area of this new eyepiece is more than 50% larger than an 82° field. The Tele Vue Ethos is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.

Annals of the Deep Sky - Vol 9 is a comprehensive reference that guides amateur and semipro astronomers into every mind-boggling corner of the observational universe. Each volume presents extensive descriptions of prominent stars and deep-sky objects. No other popular work in astronomy provides the comprehensive historical background and astrophysical appraisals of prominent stars and celestial objects.

This volume is dedicated to the Milky Way’s nearest and largest satellite galaxies, the Magellanic Clouds. Throughout history they have been the subject of awe and wonder, catching the eye of Indigenous peoples of Australia and New Zealand, 16th century mariners, and astronomy’s pioneer observers such as Nicolas-Louis de Lacaille, James Dunlop, and John Herschel. In the late 19th and early 20th centuries, northern astronomers began traveling to the Southern Hemisphere to photograph, map out, and study the celestial constituents of what they referred to as Nubecula Major and Nubecula Minor. This book presents not only a thorough historical account of the clouds dating back 40,000 years, but also how astronomers’ ideas of the Clouds have changed over the decades — particularly on the Clouds’ origins, interactions with the Milky Way, and the quizzical aspects of star formation posed by their many unusual clusters and H II regions. Come discover the observational richness and astrophysical conundrums that are the Magellanic Clouds, true treasure islands lying just beyond our Galactic shores.

Annals of the Deep Sky - Vol 9 also includes two special fold-out maps for exploring the Magellanic Clouds in more detail, one showing the Large Magellanic Cloud and the other the Small Magellanic Cloud plus extra detail on the Tarantula Nebula, the star-forming region also known as 30 Doradus.

Author Jeff Kanipe has released the latest edition of this great series and for those of us in the South we are blessed. Volume 9 covers the Magellanic Clouds. Definitely will be in my Library of Southern Hemisphere books, can’t wait.

Review

An excellent premium quality low power eyepiece. It is ideal for observing large emission and reflection nebulae, Supernova Remnants and large open star clusters.

It is very well suited to large f/4.5 Dobsonians giving 6mm exit pupil. Is a great low power eyepiece in short focal length refractors, for example, with the TV 102, it gives 31x and a true field over 130 arc minutes.

It has 16mm of eye relief and can be used by eyeglass wearers with no vignetting of the field. Images are sharp right to the edge of the field.

This is a lot of eyepiece so its heavy weight may cause some minor concern in Dobsonians. One of the favourite eyepieces of Bintel's Technicians.

Installation Guide

Product Description

ASI294MM-P is a back-illuminated, 4/3” format, 14-bit ADC camera with 4.63um pixels *(. It is the mono version of ASI294MC Pro, one of the top selling cameras from ZWO. It has an impressive 66ke- full well capacity and 4144*2822 big resolution.

Not only does it have a very high QE value with a peak at about 90%, but feature an ultra-low readout noise of 1.2e. If you are seeking for a small-format mono camera for astrophotography, then ASI294MM-P gonna be your ideal choice.

14-bit ADC and 13stops dynamic range

ASI294MM Pro has very similar parameters as its color version. Both have the 14bit ADC and a high dynamic range of 13 stops, which is even higher than that of ASI1600MM Pro camera.

Unlocked Bin1 Mode

Yet another perk of the ASI294MM Pro is that the pixel size is switchable – the default setting is Bin2, but you can switch to Bin1 anytime in your astrophotography software. This changes the pixel size into 2.3um and increases resolution to 8288×5644. This is what we called “Unlocked Bin1 Mode”. The ability to unlock bin1-mode was a popular request from our customers. Of course we listened to you and worked quickly to make it possible.

Remember that using Bin1-mode will decrease the full well capacity compared to the standard bin2-mode.

Unlocked Bin1: 12bit ADC, 2.3um pixel size, 47 megapixels, 8288*5644 resolution, 14k full well capacity.
Bin2: 14bit ADC, 4.6um pixel size, 11.7 megapixels, 4144*2822 resolution, 66k full well capacity.

Backlit Sensor

The back-illuminated CMOS sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.

With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.

Camera Performance

Large well depth capacity, low read-out noise and high dynamic range.

The full well capacity of 66387e of ASI294MM Pro is near the top of all ASI DSO cameras. It ensures a very high dynamic range up to 13stops that will greatly reduce overexposure probability and help gain richer color gradation.

When the gain value is 120, the magical HCG high gain mode is turned on, the readout noise will be largely decreased (as low as 1.2e), and the dynamic range is basically unchanged.

Reliable Mechanics

There are four screws on the camera that seal the sensor chamber. This kind of design has been extensively tested and is very stable. Even when used in higher humidity environments, ASI294MM Pro will still work fine without dew problems.

The anti-dew heater power is around 5W and can be turn off in software to save power.

QE Value

As ZWO’s latest BSI (backside illuminated type) mono camera, ASI294MM Pro has very high QE performance, not only higher than its color version, but even ASI1600MM Pro. It is estimated that the QE peak value is about 90%.

Two-Stage TEC Cooling: Ultra-Low Dark Current

ASI294MM Pro uses two stage TEC cooling that can lower the CMOS sensor temperature to 35c~40c below ambient, which can greatly reduce dark current generation and sensor noise even with extended exposure times.

The unique dark current suppression technology can even further reduce dark current noise. When it’s cooled to -20℃, the current noise can be as low as 0.0022e/s/pix, which is completely negligible!

Please notice that the camera needs to be connected to an external 12v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-15V to power the camera.

USB3.0 & 256M DDR3 Memory

The ASI294MM Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB(2Gb) DDR3 cache to ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
