Beautiful shot Wilson!
I seconded that! Seriously nice work! And nice sky kat Sibu tu...  Sedikit tambahan, apa kata kita cuba cari identify object yang paling kelam (faintest magnitude) yang ada dalam gambar wilson tu, boleh guna mana-mana perisian sebagai panduan...  |

Saya rasa tak, kerana imej Musytari tu pun nampak overexpose. Terlalu 'besar' untuk cam mana-mana satu drpd bulan Galileans. Lagipun jarak bulan-bulan Galilieans dari Musytari pun tak lebih dari 1/30 darjah! Memang tidak memungkinkan kita nampak menerusi foto ini. |

nice wide field!!!!! Kalau guna slides, lagi best! Tommy Tommy, Boleh cerita sikit, apa kelebihan kalau guna slides? Saya tak pernah guna ..so tak boleh nak imagine.. Sebelum saya guna DSLR, saya pernah guna slides film for astrophotograhy. Definition nya: Slides are still generally preferred by professionals and many amateurs when working with traditional film. Slides are often sharper and have better color reproduction. Generally, slides have a longer life span than color prints. Kebaikan slides ialah ia boleh push 1 or 2 stops on the negative. But cost of developing akan menjadi mahal. Jadi, setiap kali kalau saya nak buat astrophotography, saya akan plan dulu session yang mana saya akan guna slides rather than using DSLR. Maybe for Star trails or milky way shot, I will try to use my Old mechanical SLR with slides film to do long exposure. Contohnya,    Regards, Tommy |

Betullah shah, ingatkan dot sebelah Jupiter tu one of the Galilean moons. Ada beberapa lagi Messier Objects dlm pic tu, tapi susah nak make out. Close to Antares sepatutnya ada M4, tapi susah nak make out. |

Date: 10/6/07 Time: around 11pm Place: Sibu, Sarawak Camera: Canon Powershot S3 IS stacked: 26 frames (15s each) using Deepsky stacker OK . my take on Shah's challenge. Using Photoshop 1. my picture of the same part of the sky lebeh kurang,  single frame with Canon EOS 20D and canon 50mm f1.4 6s f/1.4 at 50.0mm iso800 2. Next I rotated to match wilsontie pic  3. followed by adjusting scale to match and stack onto wilsontie pic  and viola no prizes for guessing Anybody want to try using the skychart. 
cheers |

Wah... great light abg aziz. Cuba tengok berapa banyak light photon yang boleh menerjah masuk ke ccd sensor jika lens anda mampu stop sampai f/1.4 itu baru 6 saat jer tu... Cuba imagine, let say guided 60 saat mesti kita orang semua dah tak boleh kenal pasti buruj2 dalam imej tu dah terlampau crowded dengan bintang2 dan dust  |
