| 説明 | Pembrokeshire has areas where the sky is truly dark .Pick a clear night , around the time of a New Moon . The "Philips Planisphere Disc" can be used to find the position of The Night Stars , including The Milky Way , throughout the year .The Milky Way is a spiral Galaxy , one of billions of galaxies in the universe . It is the home of our Solar System together with at least 200 billion other stars . The Milky Way is seen as a luminous band of light and stars that stretch across the night sky , from the northern to the southern horizon .It is composed primarily of stars that are too faint to be resolved so that we see their combined light as a faint glow. The centre of the galaxy lies in the direction of Sagittarius and it is here that the Milky Way looks brightest .The Milky Way isn't as bright in the Winter (Oct- April) , as the view is away from the Galactic Core to the outer rim.Photo Info :- 30secs / 3200asa / f4 / 17mm Lens.A "dark frame", ie a photo taken with the Lens Cap on , is worth taking as it can be used to remove "Hot Pixels" from the photo and may help to reduce noise . For details of taking astrophotos with longer exposures , the website www.astrotrac.com , has British Manufactured autoguiding gear and sample photos. 9328 / Skrinkle Haven |
