Review ASKAR F4.5 40mm Astrograph Telescope

The Askar FMA180 F4 40mm Astrograph Telescope is an impressive optical instrument designed for astrophotography and visual observation of celestial objects. This telescope boasts a high-quality, fully multi-coated 40mm (f/4) Quartz glass objective lens, which delivers exceptional light gathering ability and excellent image contrast and brightness.

The optical tube of the Askar FMA180 is constructed from high-quality aluminum alloy and features a collapsible design for easy transportation and storage. The tube length is 300mm (11.8 inches) when collapsed, making it highly portable. The tube diameter measures 180mm (7 inches), providing a generous aperture for capturing detail in deeper sky objects.

This astrograph telescope comes with a 50mm (2 inch) dual-speed (250/500 RPM) Crayford focuser that offers fine focus adjustments, enabling sharp and precise focus on celestial objects. The focuser's height adjustment provides flexibility for camera attachments.

The included fitting for the Vixen dovetail mounting plate allows for easy attachment to your equatorial mount for optimal tracking and alignment. The dew shield accessory that comes with the telescope protects the lens from the unwanted effects of dew and humidity, ensuring uninterrupted observing sessions.

The Askar FMA180 F4 40mm Astrograph Telescope is ideally suited for astrophotography with a film or DSLR camera due to its excellent image quality, collimated optics, and fast f-ratio. For visual observation, the telescope's wide field of view and high image brightness make it an excellent choice for observing star clusters, galaxies, and other deep sky objects with ease and clarity.

In summary, the Askar FMA180 F4 40mm Astrograph Telescope represents an excellent value for those interested in astrophotography and visual observation. Its high-quality optical components, robust construction, and versatile capabilities make it a must-have for keen astronomers who desire a telescope that delivers exceptional performance and portability.

The Askarnas ASF180 f/4 400mm Astrograph telescope is a compact and lightweight optical tube designed primarily for astrophotography use. Let's examine its key advantages and disadvantages to help you make an informed decision.

1. Optical Performance: The ASF180 f/4 is an f/4 Newtarian reflector with a 400mm focal length that provides excellent optical performance, high contrast, and sharp images with high magnification.

2. Compact and Portable: With a diameter of 180mm and a focal length of 400mm, the ASF180 f/4 is a compact astrograph telescope that is easy to transport, making it an ideal choice for those who enjoy astrophotography on the go.

3. Imaging Capabilities: Its long focal length and fast f-stop make this telescope an excellent choice for capturing deep-sky objects like galaxies, nebulae, and star clusters. It is also suitable for lunar and planetary imaging.

4. Affordable: The ASF180 f/4 is an affordable astrograph telescope, making it an accessible option for photographers on a budget.

1. Manual Focus: This telescope does not come with an autoguider or computerized focus control, meaning that focusing is manual and time-consuming.

2. Mount Compatibility: The ASF180 f/4 may require a heavy-duty mount for adequate support, especially for imaging long exposure images.

3. Collimation: This telescope requires regular collimation to ensure that all elements are properly aligned for optimal performance.

4. Accessories: While the ASF180 f/4 comes with some basic accessories, such as the primary mirror cell and a dew heater, it does not include a mount or a camera, which must be purchased separately.

The Askarnas ASF180 f/4 400mm Astrograph telescope offers impressive optical performance and portability at a relatively affordable price. Its drawbacks include the lack of autoguiding or computerized focus and the requirement for a sturdy mount. After considerations of these factors, it is recommended for amateur astrophotographers and those who wish to pursue deep-sky imaging with a portable setup while remaining budget-conscious.

Details:

But the ordinary cameras are not specialized for , so images taken by them may always satisfying. The Askar FMA180 originally has an aperture of 40mm, a focal length 220mm and ratio f/5.5. Besides, it can also function as a quality finder or guider. Please see the following images that I have taken with scope.

In the field of amateur astronomy, it is rare to find an astrograph with a focal length less than 200mm, which conventionally speciality ordinary cameras. The included reducer for Askar FMA180 also adopts APO triplet design, offering a sharp image when cooperating with the objective lens. ASKAR FMA180 objective lens features Triplet air-spaced APO design,including two pieces of ED extra-low dispersion glass, providing excellent correction chromatic aberration,which lays the foundation for high quality and observation.
