Since Pluto is no longer a planet, the privilege to be the last planet of the Solar System belongs to Neptune. Neptune is after Jupiter and Saturn the third most-massive planet. It has approximately 17 times more mass than Earth. One year on Neptune takes 164.8 years, because the distance between Sun and Neptune is 30 times longer than between Earth and Sun. The planet got its name from Roman mythology, specifically after the god of the sea – the mighty Neptune.
Neptune cannot be spotted by a naked eye, therefore one needs telescope. Even if you have one and you manage to find it, you will not see any details on Neptune’s surface. You will see just boring small spot.
The picture was taken by my biggest telescope Celestron C14. The focal length 4000 mm was increased by 1.6 Barlow lens to 6400 mm. The seeing was, as usual, very bad, therefore there are no details visible and the picture looks not perfectly focused and unsharp. I just wanted to try to capture it and here is the outcome:
|Telescope:||Celestron EdgeHD C14|
|Focal length:||6256 mm|
|Exposure:||1000xL (35% used), 610 ms, Gain 353|
