Telescope Refractor
Telescope Refractor (Product Code: SLE/M/47) is a 70 mm refracting telescope used to observe the Moon, bright planets and distant land objects in school astronomy clubs, geography lessons and outdoor science activities. It has a 400 mm focal length, two eyepieces giving 20x and 40x, an altazimuth mount and a full-size aluminium tripod that packs into the included backpack. This portable addition to optics lab equipment in India is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Refractor Telescope Used For?
A small refractor gives students their first real look at the night sky: craters along the Moon’s terminator, the changing phases of the Moon and the brighter planets. Because the erect-image diagonal shows land views the right way up, the same telescope works in daylight for bird watching, reading distant signs or studying a landscape during a geography field visit.
Begin with the 20 mm eyepiece (20x) to find a target, centre it with the altazimuth mount, then change to the 10 mm eyepiece (40x) for closer detail. Let the telescope sit outdoors for a few minutes before observing, and never aim it at the Sun. Packed in its backpack, it travels easily to observation nights and complements school physics lab equipment in India used for lens and optics practicals.

Frequently Asked Questions
What magnifications does the Telescope Refractor give?
The Telescope Refractor gives 20x with its 20 mm eyepiece and 40x with its 10 mm eyepiece; both eyepieces are part of the listing. Start at 20x to find a target, then switch to 40x for a closer view.
What aperture and focal length does the Telescope Refractor have?
The Telescope Refractor has a 70 mm (2.76 in) aperture and a 400 mm (16 in) focal length. Its coated glass optical elements are there to give clear, crisp images of the Moon, bright planets and distant land objects.
Can the Telescope Refractor be used for daytime land viewing?
Yes. The Telescope Refractor uses an erect-image diagonal, so views are correctly oriented rather than upside down. That makes it suitable for watching birds, landscapes and distant buildings in daylight as well as for night-sky observation.
How portable is the Telescope Refractor?
The Telescope Refractor weighs 3.3 lb (about 1.5 kg), and the telescope and its preassembled aluminium tripod both fit inside the included custom backpack. Set-up is quick and needs no tools, which suits field trips and evening observation sessions.
Can the Telescope Refractor be pointed at the Sun?
No. Never point the Telescope Refractor at the Sun or look at the Sun through it, because this can seriously injure the eyes. Solar viewing needs a purpose-made solar filter, so ask us on the contact page before planning it.
Who supplies the Telescope Refractor?
The Telescope Refractor is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company quotes schools, colleges, astronomy clubs, dealers and importers in India and international markets for single units or class sets.
What should a Telescope Refractor quotation request include?
A Telescope Refractor quotation request should state the number of telescopes, the delivery location and any related items such as globes or compasses. Sharing how many student groups will observe at once helps us suggest a sensible quantity.
