SubhanaAllah lama tak masuk sini...huhu
ni sy nak tumpang tanya sket yer pada semua as this thread is for beginner.
satu yg saya tak faham tentang teleskop jenis pantulan ialah, cermin pemantul numbor 2 dia duduk di tengah2 view terowong/kon teleskop tu,
so tidakkan ia menghalang pandangan atau menghasilkan bayang???
mohon pencerahan. |

yess....itu lah soalan sy....
at least mesti ada bayang sikit....sebab ia halang sikit,
kita anggap cermin cengkung tu bumi la...
hehe, camtue laa...
dan bulan adalah secondary mirror... |

hmmm pasal tu ye .. tak reti nak cakap camne, tapi ussopp leh cuba baca ni :
Isaac Newton developed the reflector about 1680, in response to the chromatic aberration (rainbow halo) problem that plagued refractors during his time. Instead of using a lens to gather light, Newton used a curved, metal mirror (primary mirror) to collect the light and reflect it to a focus. Mirrors do not have the chromatic aberration problems that lenses do. Newton placed the primary mirror in the back of the tube.
Because the mirror reflected light back into the tube, he had to use a small, flat mirror (secondary mirror) in the focal path of the primary mirror to deflect the image out through the side of the tube, to the eyepiece; otherwise, his head would get in the way of incoming light. Also, you might think that the secondary mirror would block some of the image, but because it is so small compared to the primary mirror, which is gathering a great deal of light, the smaller mirror will not block the image.
In 1722, John Hadley developed a design that used parabolic mirrors, and there were various improvements in mirror-making. The Newtonian reflector was a highly successful design, and remains one of the most popular telescope designs in use today.

hahaha...nice....
thank you very much.....
so this is my last question,
adakah ia menghalang sedikit, cuma ia terlampau sedikit sehingga boleh diabaikan,
atau ia tidak menghalang langsung? |

bintang tak dpt tgk dgn teleskop.... maksudnya, bintand di langit mlm...akan nmpj dlm bentuk titik cerah sahaja.... dgn maginitud2 (kecerahan) tertentu.
satunya2 bintang yg boleh tgk dgn teleskop = matahari. dgn syarat kena pakai solar filter...
rosak mata kalau di fokuskan ke matahari...
objek indah di langit adalah seperti berikut;
1. planet2 sistem solar.... biasanya akan zoom dahulu kepada jupiter (musytari) sbbnya ia paling besar dan mudah dikesan...
neptune, dgn gegelang keliling planet tersebut.
2. komet2 - ikut masa, kitaran, biasanya akan berbentuk objek dgn bahagian depan yang cerah, dan di ikuti dgn ekor, yg bercahaya...kesan reaksi/ refleksi dgn matahari sistem suria kita..
3. Deep space object.... banyak... galaksi, nebula, gas.... bergantung kepada sistem teleskop yang diguna, ada yg dah preset lokasi objek berikut dgn sistem computer teleskop terssbut, makanya ia akan mencari dgn mudah...
aktiviti pencerap adalah, capture gmbr2 objek tersebut.... |
