Space OTAs are high end optical tube assemblies made to the best quality standard. With a range of optical systems, from Maksutovs to the high end ED refractors, the OTAs are compatible with almost all available mounts.

Is the main mirror in the telescope. It is the major component of a telescope.  Light from the source falls on this mirror first and is reflected back to the secondary mirror. Primary mirror should be choosen very carefully because the edges of the mirror is normally not polished which in turn do not reflect the light from that surface which have not been polished effectively.

A range of portable telescope with added optics to present an erect im age, optimized for the observation of terrestrial objects. They are used for birdwatching and other naturalist activities, for surveillance, and for any other applications that requires more magnification than a pair of binoculars. With variable Zoom eyepiece to give a range of magnifications.

Solar filters Solar filters permit the safe observation of the sun with a telescope.Solar Filters are used to reduce the visible and Infra Red Rays of Sun which can damage the eyes permanently. There are many kind of Solar Filter available in the International Market depending upon the degree of intensity. These films are used for various purposes like Photography, Viewing etc.

Red Dot Finder : The LED illuminates a pin-hole at the focus of the lens. The eye sees an image of the pinhole at infinity. You use the finder with both eyes open, one eye looking into the lens, the other looking at the sky. Your brain superimposes the image of one eye upon that of the other and the visual effect is that you see a red dot placed on the sky.

A laser pointer is most commonly used to project a point of light to highlight items of interest during a Night Observation. You can use it to show any particular star, the beam of light is so intense that it seems you are touching the star with the help of the laser beam. This instrument is very useful for conducting Night Observations.

Is a refractor telescope with Achromatic doublet lens system. The objective diameter of the lens is 38mm. This scope is a perfect scope for beginners with low budget. This telescope is designed on the model which Galileo used 400 year back to view Moons of Jupitor. The advantage of this scope is that it can see upto 7 mag star. This scope was made keeping in view the IYA 2009 in which GALILEOSCOPE was a Cornerstone Project of IYA 2009 adapted by United Nations. This scope is available in different Colours for the tube. It is mounted on a alumunium stand with Alt-Az Movements of the Mount. Projects which can be done by this scope has been designed by SPACE. Download the Pdf file to read the instructions to start the project. It contains Project details and observation sheets on which one can log on the findings and record the Observations. After the project is over it can be submitted back to SPACE and we will send it to the international scientific community  

The compound Plössl lens provides a large apparent field of view along with relatively large FOV. This makes this lens ideal for a variety of observational purposes including deep sky and planetary viewing.The chief disadvantage of the Plössl optical design is short eye relief,[citation needed] which is restricted to about 70-80% of focal length. The short eye relief is more critical in short focal lengths, when viewing can become uncomfortable. This eyepiece is one of the more expensive to manufacture because of the quality of glass, and the need for well matched convex and concave lenses to prevent internal reflections. Due to this fact, the quality of different Plössl eyepieces varies. There are notable differences between cheap Plössls with simplest anti-reflection coatings and well made ones

This is the most economical telescope designed keeping in view the telescope designed by Galileo to view the sky. This is an Achromat telescope with tripod. This scope can be used to view the Moons of Jupiter. A project can be done using this telescope to revive the findings of Galileo. In the sky when Jupiter is visible in the night sky, use this telescope to view the moons of Jupiter at the same time each day. The four moons of Jupiter will be visible and they will change their position each day. Children can prepare a chart of their respective locations each day. After some days the moons will repeat and come back to their initial positions. This will show their movement paths duration of their movements around the Jupiter. SPACE LAUNCHER series telescopes is a wonderful collection of scopes which opens the magical world of Astronomy for young and budding Astronomers.

A Barlow is a negative (diverging) lens that is placed between the objective lens (or primary mirror – from now on these words will be used interchangeably) and the eyepiece of a telescope. It increases the effective focal length of an objective lens, thereby increasing the magnification. The idea is that 2 eyepieces and a Barlow will give you the flexibility of magnification of 4 eyepieces, and will give higher magnifications with less powerful eyepieces.   What are its Advantages and DisadvantagesAssuming that the Barlow is a good one, the only disadvantage is a slight loss of light throughput – this is of the order of 3%. The advantages are numerous: Higher magnifications can be attained with longer focal-length eyepieces than would be possible without the Barlow. Short focal length eyepieces necessarily have optical surfaces that are more curved and therefore are likely to introduce more aberrations. A Barlow increases the effective focal ratio of the objective. This gives a more acute light cone, which is less demanding of eyepiece quality because: Rays at the periphery of the cone are closer to being paraxial and thus are less subject to aberration. A smaller area of the field lens is used. Many eyepieces have an eye relief (distance of exit pupil from eye lens) that is directly related to its focal length. For example, the eye relief of a Plössl is 0.73 × its focal length. Thus, with these eyepieces, for a given magnification there will be greater eye relief with a barlow than without. Many eyepiece types do not work well with short focal-ratio objectives. The Barlow effectively increases the focal ratio, allowing the eyepiece to work well.
