An astronomical interferometer or telescope array is a set of separate telescopes, mirror segments, or radio telescope antennas that work together as a single telescope to provide higher resolution images of astronomical objects such as stars, nebulas and galaxies by means of interferometry.
Interferometer astronomi adalah array teleskop atau segmen cermin yamg bertindak bersama-sama untuk menyelidiki struktur dengan resolusi yang lebih tinggi dengan cara interferometri.
Thus it is mainly useful for fine resolution of more luminous astronomical objects, such as close binary stars.
Dengan demikian hal ini terutama berguna untuk resolusi halus dari objek astronomi lebih bercahaya, seperti bintang biner dekat.
Interferometry is most widely used in radio astronomy, in which signals from separate radio telescopes are combined.
Interferometer astronomi secara luas digunakan untuk astronomi optik, astronomi inframerah, submillimetre astronomi dan astronomi radio.
Astronomical interferometers can produce higher resolution astronomical images than any other type of telescope.

A fine guidance sensor (FGS) is an instrument on board a space telescope that provides high-precision pointing information as input to the telescope's attitude control systems.
Fine Guidance Sensor (FGS) adalah alat interferometrik yang dimuat di teleskop luar angkasa Hubble.
Hubble Space Telescope FGS
Teleskop luar angkasa Hubble memiliki tiga FGS.
The Hubble Space Telescope has three fine guidance sensors (FGSs).
Teleskop luar angkasa Hubble memiliki tiga FGS.
Two are used to point and lock the telescope onto the target, and the third can be used for position measurements – also known as astrometry.
Dua alat digunakan untuk menetapkan posisi teleskop, sementara yang ketiga untuk pengukuran posisi.
Because the FGSs are so accurate, they can be used to measure stellar distances and also to investigate binary star systems.
FGS juga dapat digunakan untuk mengukur jarak bintang dan memeriksa sistem bintang biner.
Adaptive optics (AO) is a technique of precisely deforming a mirror in order to compensate for light distortion.
Optik adaptif atau Adaptive optics (AO) adalah teknologi yang digunakan untuk meningkatkan kinerja sistem optik dengan mengurangi efek distorsi muka gelombang.
It is used in astronomical telescopes and laser communication systems to remove the effects of atmospheric distortion, in microscopy, optical fabrication and in retinal imaging systems (ophthalmoscopy) to reduce optical aberrations.
Hal ini digunakan dalam teleskop astronomi dan sistem komunikasi laser untuk menghilangkan efek distorsi atmosfer, dalam mikroskop, fabrikasi optik dan dalam sistem pencitraan retina untuk mengurangi penyimpangan optik.
Adaptive optics works by measuring the distortions in a wavefront and compensating for them with a device that corrects those errors such as a deformable mirror or a liquid crystal array.
Optik adaptif bekerja dengan mengukur distorsi wavefront dan kompensasi bagi mereka dengan perangkat yang mengoreksi kesalahan-kesalahan seperti cermin mampudeformasi atau array kristal cair.
Adaptive optics should not be confused with active optics, which work on a longer timescale to correct the primary mirror geometry.
Optik adaptif tidak harus bingung dengan optik aktif, yang bekerja pada skala waktu lebih lama untuk memperbaiki geometri cermin primer.
Other methods can achieve resolving power exceeding the limit imposed by atmospheric distortion, such as speckle imaging, aperture synthesis, and lucky imaging, or by moving outside the atmosphere with space telescopes, such as the Hubble Space Telescope.
Metode lain dapat mencapai menyelesaikan kekuatan melebihi batas yang dikenakan oleh distorsi atmosfer, seperti belu pencitraan, sintesis aperture, dan pencitraan beruntung, atau bergerak di luar atmosfer dengan teleskop ruang angkasa, seperti Hubble Space Telescope.

An equatorial room, in astronomical observatories, is the room which contains an equatorial mounted telescope.
Ruang equatorial, di observatorium astronomi, adalah ruang yang berisi teleskop khatulistiwa terpasang.
It is usually referred to in observatory buildings that contain more than one type of instrument: for example buildings with an "equatorial room" containing an equatorial telescope and a "transit room" containing a transit telescope.
Hal ini biasanya disebut di gedung-gedung observatorium yang mengandung lebih dari satu jenis instrumen: Misalnya bangunan dengan "ruang khatulistiwa" yang berisi teleskop khatulistiwa dan "ruang transit" yang berisi teleskop angkutan.
In some cases an observatory would move to a new location, or the equatorial telescope itself would be removed.
Dalam beberapa kasus sebuah observatorium akan pindah ke lokasi baru, atau teleskop khatulistiwa itu sendiri akan dihapus.
The space would then be converted, for example, into use as a classroom or library.
Ruang kemudian akan dikonversi, misalnya, mulai digunakan sebagai ruang kelas atau perpustakaan.
In astronomy, first light is the first practical use of a new instrument, typically a telescope to take an astronomical image after it has been constructed.
Pada astronomi, cahaya pertama merujuk kepada penggunaan pertama suatu teleskop (atau secara umum, sebuah instrumen baru) untuk mengambil gambar antariksa setelah instrumen tersebut dibangun.
In amateur astronomy, "GoTo" refers to a type of telescope mount and related software that can automatically point a telescope at astronomical objects that the user selects.
Dalam astronomi amatir, GoTo mengacu pada jenis teleskop mount terpasang dan perangkat lunak terkait yang secara otomatis dapat menunjuk teleskop untuk objek astronomi yang diplih pengguna.
The user can command the mount to point the telescope to the celestial coordinates that the user inputs, or to objects in a pre-programmed database including ones from the Messier catalogue, the New General Catalogue, and even major Solar System bodies (the Sun, Moon, and planets).
Hal ini memungkinkan pengguna untuk perintah mount untuk menunjukkan teleskop untuk kenaikan yang tepat dan deklinasi bahwa pengguna input atau memiliki mount sendiri menunjuk teleskop ke objek dalam data base yang telah diprogram termasuk yang dari katalog Messier, New General Catalogue, dan bahkan badan tata surya utama (matahari, Bulan, dan planet-planet).
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.
Teleskop atau teropong bintang adalah sebuah instrumen pengamatan yang berfungsi mengumpulkan radiasi elektromagnetik dan sekaligus membentuk citra dari benda yang diamati.
The name "telescope" covers a wide range of instruments.
Teleskop yang beroperasi berdasarkan spektrum elektromagnetik: *Links pada kategori.
For the image to be observed, photographed, studied, and sent to a computer, telescopes work by employing one or more curved optical elements, usually made from glass lenses and/or mirrors, to gather light and other electromagnetic radiation to bring that light or radiation to a focal point.
Agar gambar dapat diamati, difoto, dipelajari, dan dikirim ke komputer, teleskop dilengkapi dengan menggunakan satu atau lebih elemen optik lengkung, biasanya terbuat dari kaca, untuk mengumpulkan cahaya dan radiasi elektromagnetik lainnya ke titik fokus.
Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites (including transits), spotting scopes, monoculars, binoculars, camera lenses, and spyglasses.
Jenis teleskop (biasanya optik) yang dipakai untuk maksud bukan astronomis antara lain adalah transit, monokular, teropong/keker, atau lensa kamera.
There are three main optical types: The refracting telescope which uses lenses to form an image.
Ada tiga jenis optik utama: Teleskop pembiasan yang menggunakan lensa untuk membentuk sebuah gambar.
The reflecting telescope which uses an arrangement of mirrors to form an image.
Teleskop pemantulan yang menggunakan susunan cermin untuk membentuk sebuah gambar.
The catadioptric telescope which uses mirrors combined with lenses to form an image.
