Maaflah sedikit mukadimah.
Photographing an Eclipse is really four completely separate things;
Photographing the Event - the people with you and their activities such as the preparation, reaction of people before, during and after the darkness. Contoh saya difahamkan semasa di Anyer pepatung berterbangan semasa greatest darkness danTelur bediri.
Photographing the Sun before and after totality
Photographing the Corona during totality.
Watching, and Listening and Soaking for the memory banks untuk cerita semasa di perjumpaan dan ke anak cucu.
In the long term view, the last is the most satisfying task. The photos you take of the people, activities and general festival-like atmosphere are the ones you will remember and share. (contoh: tengok tu matahari sabit di baju shahgazer. Mr universe24 dengan rambutnya berdiri. segala persamaan dengan member di forum ini adalah unintentional coincidence only)

Your pictures of the sun and corona, they will look just like everyone else's, and they will be technically inferior to shots taken with amazing equipment that you can't afford. The pictures you take of the event as you experience it are uniquely yours, and do not depend on expensive equipment.
Dikalangan yang pergi bukan semuanya nak ambil gambar Diamond Ring dan Corona.
Dari 4 perkara diatas tanya yang mana satu idaman kalbu. Kalau dua pun boleh. Tiga dan empat dak tamak lah.
Lepas tu baru bincang lah apa kamera dan pelatan yang diperlukan dan belajar menggunanya . Range dari P&S compact to DSLR with 500mm telephotolense/telescope mounted on a tracking equatorial mount which weights a ton and demands your full attention to look after it. You may miss the event then all you can remember afterwards is busy manipulating your camera.
Baik tengok kebesaran Allah sambil baca Subhnallah. Allah will give you a reward.
Maaf ya. Bukat niat to take the wind out of the sails. Tapi nak remind bukan semua niat sama.
Know what you want first and then know your gadgets.

selamat maju jaya.
