Finally got my hands on my newly ordered lens that’ll aid me for Milky Way photography. It has a lower f-stop than what I’ve used before so I’m really excited to go out once we get the new moonless nights ahead of us in three weeks or so.
This suppose to be one of top three lenses for Milky Way among landscape astrophotographers using Canon cameras.
Haven’t done the Milky way in a while and this time I’ve chosen with a Canon 50D and a Canon 35mm lens. The settings were AWB, ISO 1600 and 14 seconds of exposure by using the 500-rule (500/lens mm).
The foreground is Henry Grieb Observatory – Nyack Airport in Blue Canyon, CA. Right above the dome Saturn to the left and Jupiter to the right.
I’ve now ordered Canon’s EF-S 24mm f/2.8 STM lens which apparently is one of the top 3 Canon lenses for Milky way astrophotography to try and get some better results. The lens I was using for the image above isn’t really suitable for Milky way due to high f-ratio, making it a “slow” lens in allowing faint light coming through. That night was also illuminated by the moon (the moonlight reflection can be seen on the dome itself) which makes things worse for Milky way to become more prominent in the photos.
Below are examples of how higher f-stop/f-ratio allows less light through, thus increasing your exposure time, which introduces noise and other issues such as shaking, star trails, etc.
