Planisphere Manufacturer,Supplier and Exporter in India

Product Code : SCL-A-12525

The Planisphere is an educational astronomy star chart used for identifying stars and constellations visible at a selected date and time. It is intended for schools, astronomy clubs, STEM classrooms, science laboratories and beginner sky observers who need a practical, non-electronic tool for learning the seasonal appearance of the night sky.

Product Description

The Planisphere, also known as a star wheel, typically consists of a rotating circular star map and an overlying window representing the visible sky. By aligning the required date with the local observing time, users can view an approximate map of the stars and constellations above the horizon.

A planisphere is normally designed for a particular latitude range because the visible sky changes with geographic latitude. The exact latitude coverage, material, diameter, star magnitude limit, constellation artwork and astronomical epoch of this product should be confirmed before publication or procurement.

Key Features

• Date-and-time sky selection: helps users identify the approximate night sky visible for a chosen observing time and date.
• Constellation identification: supports practical recognition of major constellations shown on the supplied chart.
• Seasonal sky learning: demonstrates how different star patterns become visible during different times of the year.
• Manual operation: requires no electricity for basic use.
• Hands-on astronomy learning: connects classroom star charts with real outdoor sky observation.
• Reusable teaching aid: suitable for repeated astronomy lessons, observing sessions and science activities.

Technical Specifications

What's Included in the Kit

• 1 Planisphere rotating star chart
• Instruction sheet or observation guide
• Protective sleeve or storage packaging

Applications / Uses

• Identifying stars and constellations visible at selected dates and times.
• Teaching seasonal changes in the observable night sky.
• Supporting school astronomy lessons, STEM activities and astronomy clubs.
• Preparing students for supervised outdoor sky-observation sessions.
• Extending constellation studies with the Constellation Viewer Model.
• Comparing apparent sky observation with planetary-motion demonstrations using the Orbit Orrery.

How to Use the Planisphere

1. Confirm that the planisphere is suitable for the latitude of the intended observing location.
2. Rotate the star chart until the required date aligns with the intended local observation time.
3. Read the visible-sky window to identify the stars and constellations predicted to be above the horizon.
4. Orient the planisphere according to the viewing direction shown on the chart.
5. Compare prominent star patterns on the planisphere with the actual night sky.
6. Repeat the activity at different dates or times to observe how the visible star patterns change.

Safety note: A planisphere is intended for night-sky orientation and should never be used for direct solar observation. Do not look directly at the Sun through any optical device unless that equipment is specifically designed and certified for safe solar viewing.

Care & Maintenance

• Keep the rotating chart clean, dry and free from excessive dust.
• Avoid bending, crushing or forcing the rotating components.
• Protect printed surfaces from moisture and unsuitable cleaning chemicals.
• Store flat or in the supplied protective packaging after use.

Why Choose School Equipments

School Equipments manufactures and exports scientific laboratory instruments, astronomy teaching aids, science kits, mathematics kits, didactic models and STEM equipment for educational institutions. Its astronomy range supports practical teaching of stars, constellations, celestial motion, planetary systems, Moon phases and other space-science concepts.

Educators can combine the planisphere with the Astronomy Lab Kit for broader classroom activities. Final latitude range, chart content, material, dimensions and included accessories should be confirmed before ordering.

Frequently Asked Questions

What is a Planisphere used for?

A Planisphere is used to identify stars and constellations that should be visible at a selected date and time from an appropriate geographic latitude.

How does a Planisphere work?

The user rotates a circular star chart to align a date with a time. A viewing window then displays an approximate map of the sky visible for that setting.

Does a Planisphere work anywhere in the world?

Not necessarily. Planispheres are generally designed for particular latitude ranges because the visible night sky changes with geographic latitude. The latitude coverage of this model must be confirmed.

Can a Planisphere show planets?

A conventional planisphere is primarily used to show stars and constellations. Planet positions change relative to the background stars, so they generally cannot be permanently plotted in the same way.

Is a Planisphere suitable for school astronomy lessons?

Yes. It is useful for supervised classroom teaching, astronomy clubs, STEM activities and introductory night-sky observation.

Does a Planisphere require electricity?

No electricity is normally required for a conventional rotating star-wheel planisphere. Users manually align the date and time scales.
