Assalamualaikum.

Saya meluangkan masa mencerap sambil menguji (mempelajari) dua kamera berbeza, 20Da dan 1000d Cannon. Saya, bersama WANZR mengambil gambar nebula Trifid dan Lagoon melalui teleskop Pantex F/4 (Pinjam DR.Rowi punya).

1.


2.


Did you see the difference, ada apa-apa perbezaan?

Struktur nebula pada gambar kedua lebih bagus. Adakah gambar kedua diambil dgn 20Da?

Adakah gambar2 ini telah diproses? atau diambil dalam RAW? Setting (exposure) camera pun sama atau berlainan?

Apapun, detail dalam 2nd image is far better. The H-alpha wavelength is better define. And the noise is far less than the 1st image.

1st image is quite noisy. And hard to see H-alpha emission? Not so sure here. But I do think that either the ISO is higher or the exposure time is longer in the 1st image.

So I would concur with Mr Universe to say that the 2nd image is taken by the 20Da. But do correct us if we're wrong.
