Eyepieces - The 15 mm and 6 mm 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 15 mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 6 mm Plossl provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2x Barlow Lens - Insert the 2x Barlow Lens between the eyepiece and the telescope and it doubles the magnification of any 1.25” eyepiece. That means the 15 mm Kellner included in this kit will double in power, effectively becoming a 7.5 mm eyepiece, and the 6 mm will provide the magnification of a 3 mm. Any other 1.25” eyepieces you already have will also work in this versatile accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for you and your telescope. T-threads are machined into this Barlow lens, allowing a user to attach a DSLR camera with the addition of an optional T-ring.

Filters - Colored 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 the planet’s phases.

Cleaning Cloth & Case: Keep the micro-fiber cleaning cloth stashed in your AstroMaster Accessory Kit case so that it will always be handy. It’s much better to use a micro-fiber cloth on your optics than other wipes or tissue, as it does 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.

ASI183MC Pro

Introducing the ASI183 camera series, the most sensitive cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!

DDR Memory Buffer

The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

Astrophotography Performance

The ASI183 cameras has a very large full well capacity（15000e） for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

Reliable Mechanics

ASI183 Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.

Even when used in higher humidity environments, ASI183 Pro will still work fine without dew problems.

High Speed

Fast FPS can be used in solar and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

10Bit ADC
5496×3672 19fps
3840×2160 41.04fps
1920×1080 80.10fps
1280×720 117.30fps
12bit ADC
5496×3672 19fps
3840×2160 36.12fps
1920×1080 70.48fps
1280×720 103.23fps

High QE

Sony’s back-illuminated Exmor R technology, giving it excellent Deep Sky performance. ASI183 QE peak reaches a remarkable 84%. In Ha channel, QE is still over 60%.

Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than ~50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, improving your signal quality.

Dark Current

The dark current of the ASI183 is extremely low, based on our test results.

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution(20.18Mega).

Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.

Using a battery with 9-15V is also suitable for the cooler power supply.

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI183 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

Cooling System

The ASI183 Pro has a 2-stage TEC cooling system that enables deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera.

What's in the Box

The Bintel ND96 13% Neutral Density filters reduce the glare by only partially transmitting (only 13%) of the reflected light uniformly across the entire spectrum. Not only will you see more surface features, but you can study them in greater comfort. These filters also reduce irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. Screws directly into the eyepiece barrel.

The Moon’s disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view, particularly in telescopes of 6 inch aperture and larger.

With standard filter threads (M25.5 x 0.6) it can be screwed into almost any 1.25" eyepiece, 1.25" diagonal or can be stacked with other coloured filters to enhance lunar and planetary detail.

The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.

Comes in plastic case for clean, safe keeping.
