Stars in Broad Daylight (Nujum al-Nahar) Ossama Mohammed. A double wedding in a small village turns. Seeing stars and planets in the daylight. Viewing stars and planets at daytime. Introduction. Normally we can only see stars at night. The reason is obvious: with daylight the sky background is too bright to see the stars, the relatively faint points are washed out by the scattered sunlight. For us, the Sun appears 5. Sirius the brightest star in the sky. Even stories such as 'from deep pits or mine shafts it is easier to find stars on the smaller portion of the sky' are incorrect: one is 'blinded' even by the small portion of sky one sees just like one sees normally a large part of the sky. It has no scientific value but it is just a challenge until how faint one with a certain telescope (or even with the naked eye!) one can see astronomical objects in daylight. It can be fun when seeing Sirius or Betelgeuse on a hot North American or European summer day with the telescope ! It is even possible to see double stars at daylight (e. Mizar, Cor Caroli, Alpha Centauri). For viewing first magnitude stars a small telescope and a power op 2. Stars in Broad Daylight (1988), Leggi Stars in Broad Daylight di Robert Samson con Kobo. When, at age 39, the author is diagnosed with a life-threatening illness for which there is no cure or. In Broad Daylight is a true crime book by award-winning writer Harry N. MacLean, detailing the killing of town bully Ken Rex McElroy in 1981 in Skidmore, Missouri. It is also fun when showing it to friends, etc. My experience is that people are very amazed seeing a star or planet in bright daylight. But, in most cases just the fun or having the kick of seeing a star or planet in full daylight. Or on far northern locations such as Northern Europe have very long daylight in summer resulting in getting dark when people go to bed or even later. Viewing objects at daylight allows using telescopes and seeing some astronomical objects despite lack of a real night sky. Stars In Broad Daylight is a gritty story of faith and love, told with wit and humor. Although it deals with weighty issues it is never depressing. Stars in Broad Daylight (1988) Directed By: Usama Muhammad. Le dernier mot, Regarder Stars in Broad Daylight en HD 720p Vid Stars in Broad Daylight In nighttime this is no problem but in daytime there are only a very few naked eye objects available (in many cases only the Sun). In the latter case the telescope should be pointed at the Sun for alignment. This can be done safely when the requirements in the yellow box below are met. Hazy or milky skies with lots of dust attracting moisture or much cirrus cloud covered skies are useless unless one wants to look up Venus or the Moon. Dry and high altitude locations are the best areas like Utah, Atacama desert, Namibia, and the very best is the for the most of us inaccessible Dome C in Antarctica. But your home location can be suitable at times when the sky looks like the background color of this page. It seems contrary, but even in humid tropical environments like Indonesia, particularly during the rainy season between showers or on a clear day the skies are usually deep blue, better than in the dry season. Clear nights also show many stars in dark areas in such locations. Telescope should be properly aligned with an error no more than half a degree. Eyepiece should be prefocused properly in focus for infinity for a relaxed eye. Do this by pointing the telescope at a remote object (more than several hunderds of meters away, or better, a bright object such as the Moon or Venus, or possibly an overflying airliner). Otherwise you'll be peering into the blue void without seeing anything ! You can put a marker on the focusing barrel. Keep the telescope tube, particularly when painted with a dark color, outside direct sunlight. Heating up the telescope tube will generate turbulence inside which results in a badly blurred image. Unless you have a goto mount you must know the coordinates of the object(s) to be found. Currently most smartphones or laptops can run programs which show these coordinates. Smartphone applications such as Skysafari for i. OS and Android, Starmap for the i. Phone or i. Pad, Palm Planetarium for the older Palm. OS (for which is emulation on Android, i. OS and Symbian) are star charting programs which display the altitude of the selected object and refresh automatically. For example, below examples of Skysafari (Mac OSX, i. OS and Android, $3) which shows the altazimuth coordinates of the object centered on and are refreshed constantly. Stellarium is a freeware app for Mac OSX, Linux and Windows. Although designed for 'normal' night use these apps are an excellent helper for finding objects in the daytime. It is easy with apps such as Skysafari and Stellarium (also available on i. OS and Android, $2): search for the object with the app's search function and center the object and on top left of the screen the altazimuth coordinates are shown. See the images below (click to enlarge). If you don't have software which displays 'live' azimuthal coordinates, you can use my self made standalone HTML / javascript application which displays these coordinates in tabular form. It is further down on this page in which you can fill in your latitude and longitude and click on 'now' to get coordinates (azimuthal and equatorial) of several stars, planets, sun and moon. It refreshes every 2. As azimuthal coordinates change rapidly. When loaded in a separate page and use a modern browser with 'local storage support' (Firefox 4. Opera 3. 0+, Chrome, Safari 7+, i. Phone/i. Pad, Android) that page will be stored automatically on the device so when the site is accessed again, no internet connection is required. So you can use this site with 'live' coordinates near the telescope, even offline. You need a compass for rough celestial pole direction and an inclinometer to set the polar axis correctly. Exactly level is not required, but only roughly (a few degrees off level) is OK, unless the polar altitude is already exactly pre- configured, e. In the first case (polar altitude is not exactly aligned), put the inclinometer on the polar axis and it should read an angle equal to your latitude. Using 2. 0x which is OK at night but at daytime it 'degrades' a 1. A 2. 0cm telesope requires at least 8. So the rule is (also applies during 'normal' night operation) aperture is the smallest value of real aperture and power times eye pupil dilation. The latter is 5- 7mm at night and 2- 3mm in the daytime. This also means that 1. This makes binoculars unsuitable for stars at daylight unless you look for Jupiter, or, close to sunrise/set, a 1st magnitude star. When using a Newtonian or Dobson telescope, put the telescope in the shadow as when setup in sunlight, turbulence in the telescope tube will cause much turbulence degrading image quality considerably. Refractors don't have this problem or at most that it does not deteriorate image quality. Otherwise find first brighter objects (> +0. FOV of at least 2 degrees, which possibly degrades the aperture. For finding fainter objects or objects close to the Sun you can better use an eyepice with a higher power (but a smaller FOV) which uses the best of th aperture. E. g looking up Arcturus with a 2. FOV of 5. 0. Limiting magnitude is for the naked eye in full daylight about - 4 and for a 1. This is valid for high sun (> 4. Every 1. 6x larger diameter (and magnification) increases the limiting magnitude by 1. In the daytime the seeing is poorer than at night but usually this is not an issue when using powers up till 5. Putting the telescope in the shade makes observing of daylight objects more comfortable, particularly on a hot summer day. Moreover there will be less turbulence in the (mostly Newtonian) telescope which degrades image quality considerably even more than bad seeing. In that case, it can be seen even as close as 7. When it is between inferior conjunction and greatest elongation it is harder to see as it is fainter. Venus - Looks very bright and when close to inferior conjunction, it has a nice thin crescent and can be even seen on the day itself of the inferior conjunction in many cases. Earth - Look around you, all that belongs to Earth, no telescope needed. Mars - Even when it is only as small as 1. Even small telescopes of 8cm will show some detail. The reddish appearance has a good contrast to the blue background. Jupiter - Easy target, details visibility same as for Mars. When closer to the Sun (even as close as 2. A 2. 0cm or larger telescope will show the Galilean moons when the Sun is low and Jupiter is not too close to the Sun. Saturn - Harder to see due to the larger distance to the Sun and hence its lower surface brightness. But when transparent sky and Sun not too high, a small telescope of 8cm will show it. Uranus / Neptune - Sorry, no go. Unless, in the case of Uranus, with low Sun and a (much) brighter object is close to it which will help to find the +6 planet, but a larger telescope (2. Bright stars - Stars brighter than +1 are all accessible with a small telescope (7- 8cm) even with high Sun as long as the star is at least 3. Sun. With low Sun and further from the Sun (9. Sometimes one sees the star to be found and it turns out it is easier to be seen than expected after peering into the blue void. Stars with an orangish color such as Betelgeuse or Arcturus are a bit in favor due to the color contrasting to the blue sky. A larger telescope (2. Sun and mag 4 stars with low Sun. Double stars - There are a lot. The easiest ones are Alpha Centauri and Alpha Crucis, even visible at full daylight. Other easy examples are: Mu Bootis (4. The latter are components of +2. Nice object in daylight with low Sun. Other challenges: Albireo with a mv=+5 component and Cor Caroli with a +5. Visible in a 1. 0cm with at least 4. Sun. Deep sky objects - No way. Needs a real night sky. It is just the challenge 'how far can I go with my telescope'. The image below gives an impression of what you can actually see. The term 'naked eye' means without optical device other than ordinary eyeglasses or contact lenses. These are. GOTO mount, the easiest way. When you have a telescope with a Goto mount which usually has a tracking clock drive as well (if aligned properly), you are lucky. Some portable mounts allow two- star alignment which you can align on the Sun (watch out, do not look into the eyepiece !) and the Moon (or Venus, one of them should be available in the sky). Just type in the object name (or coordinates if there is no object database in it) and go. However, some goto mounts do not allow pointing it to the Sun, so in that case setting up on a clear night before must be done. Refer to the user manual how to do this.
