An extension of the highly popular APO140FL, the APO160FL F/7 allows the observer to delve deeper into the beauty of space.

• The TEC APO160FL F/7 features an oil-spaced apochromatic-triplet objective with a Fluorite (CaF₂) middle element, resulting in color correction that is optimized for visual use and imaging. This oil-spaced triplet design in combination with multi-layer coatings on all surfaces of the objective ensure maximal light transmission.
• The objective is housed in an aluminum cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
• The optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation – after the scope leaves TEC, no adjustment is required.
• Further, the crisp all white assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color out of this compact and timeless design.
• Each APO160FL F/7 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments’ largest rotating focuser with coarse and fine focusing 9:1 Planetary Reduction Assembly.
  • The APO160FL F/7 can be fitted with to other focuser models by request. Please contact TEC to confirm whether the desired focuser will fit with the desired TEC model.
• The 2” locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity.
• It also comes equipped with a Focuser wheel for easy mount installation and direction.
• Available for purchase as a Binocular Telescope. This requires the purchase of 2 APO160FL F/7.
• Able to accommodate a wide variety of eyepieces and mounts.

In classic refractor fashion, the TEC APO160FL F/7 is a no compromise, no frills design that lets the wonders of nature speak for themselves.

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and TEC then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach TEC's expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

Our largest refractor, the APO250VT F/8.8 allows the observer to immerse themselves in the beauty of space. This observatory class instrument provides the best visual experience that TEC has to offer.

• The APO250VT F/8.8 features an air-spaced apochromatic-triplet objective with a Fluorite (CaF₂) middle element, resulting in color correction that is optimized for visual use and imaging. This air-spaced triplet design in combination with multi-layer coatings on all surfaces of the objective ensure maximal light transmission.

The Sky-Watcher Black Diamond 130/650 Photo Reflector OTA is a 130mm aperture Newtonian reflector with diffraction limited optics, all the light gathering power you need for visual use or astrophotography! Newtonian reflector telescopes are among the most cost effective design on the market, reaching much larger apertures than an equivalently priced refractor. The large aperture will help resolve faint, extended objects like nebulae and galaxies, whilst the 650mm focal length will reveal fine details of lunar craters.

The 130/650 Photo Reflector is equipped with an excellent Crayford dual speed focuser allowing fast, coarse regulation followed by a precise 10:1 reduction adjustment knob to reach the optimal focus. A 3 element 28mm LET eyepiece is provided, allowing 23x magnification and a 56° apparent field of view with 20mm of eye relief. The aluminised primary mirror is aspheric (parabolic profile) offering an optical system free from spherical aberration. The secondary mirror is thin to allow fast cooling and it is held by extra thin spider supports for minimal diffraction spike effects on bright stars and increased contrast.

In The Box:

• SkyWatcher Black Diamond 130/650 Photo Reflector OTA
• 28mm LET Eyepiece
• 6×30 Finder Scope
• 130mm Tube Rings
• Dovetail Bar

We offer secondary flat mirrors to match the complete telescope set request, our elliptic flat mirror has the same high optical quality of our parabolic primary mirrors. All mirrors have an enhance aluminum reflective coating, reflectivity is approximately 93%. The aluminum coating is protected by a properly applied protective coating (SiO2). Any custom made flat mirrors should be welcome!

Specifications:

The essentials:

• Balanced ratio of magnification and light intensity

The essentials:

• Excellent for observations at long distances
• Safe detection and determination of details
• For the detailed, long observation, quieter picture impression when mounting on a monopod or normal tripod

This dovetail bar kit allows you to replace the wider CGE dovetail bar found on most Celestron 8” Schmidt-Cassegrain and 8” EdgeHD optical tubes with a narrow dovetail, allowing them to be used on mounts that require the narrower CG-5 dovetail bars.

The Rowe-Ackermann Schmidt Astrograph (Celestron RASA 36), is a cost-effective optical system for space surveillance, Space Situational Awareness (SSA), other scientific applications, and advanced wide field astroimaging. It offers unprecedented value in aperture, speed, field of view, and optical performance. The RASA design has a convenient external prime-focus image capture location with a flat focal plane, providing small spot sizes to the edge of a wide field. The result is images free of optical defects like field curvature, off-axis coma, and astigmatism.

The 36 cm aperture version is the largest RASA Celestron manufactures; it is the biggest and fastest (f/2.2) optical instrument of its kind available off-the-shelf. Unlike most telescopes, which only focus visible light (400-700 nm), the RASA 36 cm focuses an extended spectral range (400-900 nm), allowing a brighter signal to be detected by a camera sensor. The RASA 36 cm also features a redesigned focus system, which ensures easy and stable focusing.

RASA 36 c sample back-focus distance (77.5 mm) accommodates a wide variety of imaging sensors. A custom camera adapter can be added for a field of view up to 4.4 degrees.

Important freight requirement RASA 36 is a professional-caliber, high-precision instrument. It is manufactured and aligned to an exacting standard to provide exceptional optical performance. The telescope has been packaged to ensure it retains alignment and resulting performance during transport. However, due to the weight, size, and known stresses of shipping via parcel service, Celestron has determined that the ideal transport is a palletized delivery via LTL truck freight. For all Australian deliveries, Celestron will ship via this method. Please contact us for further freight costs

The venerable Dobsonian reflector design has recently undergone some important upgrades and improvements: Skywatcher is pleased to introduce the all-new Collapsible Dobsonian complete with Crayford focuser – the ultimate in large aperture portability and performance.

This elegant truss tube design was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the Skywatcher Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening!

The bearing system has been redesigned as well. The new Skywatcher Collapsible Dobsonians feature buttery smooth azimuth bearings. Even the twelve-inch model can be rotated with just the push of a finger. Like our traditional Dobsonians, the new Collapsible Dobsonians feature Skywatcher’s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the telescope.

To top it off, all of the new Collapsible Dobsonians are shipping with ultra smooth Crayford focusers.
