How did davie crocket die?
David Crockett was the last man to die at the Alamo in 1836 . After Santa Anna and his army won the Battle of the Alamo , they captured Mr. Crockett and made him prisoner . Santa Anna said in spanish to him , "If you wish to beg for your life , this would be the appropriate time ." He then turned to Almonte and said , "Explain this to him ." Almonte then stepped forward and said to Crockett in English , "Throw yourself on the mercy of His Excellency , Antonio Lopez de Santa Anna !" Cockett slowly looked around at the hundreds of Mexican troops surrounding him ; then looking and stareing at Santa Anna and smiling a little , he said , "You're Santanna ?" Santa Anna nodded , and Crockett said , "Thought you would be taller ." He then said to Almonte , "Tell him I am willing to discuss terms of surrender ." Almonte translated in Spanish what Crockett said , and Santa Anna smiled at Crockett , while enjoying a game of cat and mouse . Crockett said , "If the general here will have his men put down their weapons and peacefully assemble , I promise I will take you to General Houston and try my best to get him to spare most of your lives . That said (smiling a little wider ) Sam's a mite prickly ...so no promises . Tell him." Almonte hestated while glancing at Santa Anna . "Tell him!" , angrily Crockett barked . Almonte turned to Santa Anna and said in Spanish , "He wants us to surrender , Excellency ." The smile faded from Anna's face , he raised his hand and nodded to the execution squad . Castrillon ( one of Santa Anna's men ) stepped forward and said to Anna , " Excellency , please spare him !" A sergeant shouted to the execution squad , "Kill him !" Crockett said , "I'm a screamer . I got the roughest racin' horse , the prettiest sister , the surest rifle and the ugliest dog in the district . I am half horse and half alligator with a whiff of harricane ..." "Kill him !" David Crockett then said grinning , as he stared directly into the eyes of the execution squad , " I'm a screamer ..." Just then , the men moved forward swiftly and plunged about half a dozen bayonets into Crockett's chest ; killing him . Aterwards , Santa Anna's army took Travis' , Bowie's , Crockett's and the other Alamo defenders , and consumed their bodies by flames .
What is a good telescope for a junior astronomer Maximum spending limit is around 1000 I have looked at the Celestron SE series and been interested any advice is appreciated?

Cheap 'toy' telescopes are next to useless, as they claim to have great magnification, but the image is usually very poor and grainy and impossible to see properly because the optics and light gathering power are usually pretty poor. Also, the mounting of toy telescopes are usually flimsy and result in a great deal of shake. Often a good mount is as espensive as the telescope itself. A good pair of binoculars with a tripod to reduce shake should be perfectly adequate for seeing the craters on the moon, Jupiter and its moons, Venus, and large star clusters and nebulae like the Pleiades. The rings of Saturn may be too small for a small pair of binoculars, and so in this case a decent telescope is better. If you are keen on getting a telescope rather than binoculars then there are some excellent sites that will sell you one and give advice. www.telescopehouse.com is a superb UK site where you can get excellent advice and real machines that are not toys. If you are living in the UK, avoid toy 'scopes from Argos, catalogues or camera shops - they are next to useless, poorly made, shake all over the place and their optics are dreadful - and they are expensive for a pile of junk. If you wish to take up the hobby seriously, then a reflector telescope is better with a mirror of 6 inches or more, (or 8 if you live in a city - to compensate for light pollution) with a really good German Equatorial mount to avoid shake. If you can afford a motor drive too to compensate for the earth's motion then that would be an advantage. To get a variety of magnifications you will need several eyepieces of different focal lengths. Choose only reputable makes like Celestron or Meade whose optics are excellent.One last point - NEVER use a telescope to look at the sun with or without a 'safety' filter. That is the surest way of you ending up permanently blind. Dark filters may cut down the light but most of the sun's heat usually passes straight through, is focussed just like light onto your retina, ad, whilst you think everthing is Ok it merrily burns a hole in your retina just like catching a piece of paper on fire using a magnifying glass. You have been warned!
