 | Sponsored by the George H. Lutz Observatory in Mountaingate, CA., Clear Nights is a great place for amature astronomers to meet, chat, along with sharing their ideas an observing experience. So sit down, have some coffee, and please join the discussion!. Based in Los Angeles, California we provide a nice area for those who may need a platform to reach out to the astronomy community. For small astronomy related business feel free to make a post including a web link and email. Right now it is simple and basic but if matters change, rules and guidelines will have to be established Astronomy/Telescopes related topics only. Astronomy/Telescope related businesses only. If you are courteous along with using common sense in your posts and replies you should have no problems at all. It only takes a minute and it's free!I'm eager to hear comments and suggestions. In order to provide personalized services and access control, you'll need to go through a quick registration, so let's get the conversation started!

However, temperatures should be more comfortable as spring kicks in. If you are viewing with a telescope, a dew shield is a must. It prevents the scope from fogging up. However, problems of moisture formation can plague the eyepiece. These difficulties occur often at their worst as one approaches daylight. During the pre-dawn hours, you will be able to see Jupiter and Venus (the bright morning star) rising in the east. Just before the sun comes up, if you have a scope, Mercury and Neptune are visible as well.New moon occurs on May 5th; first quarter on the 12th; full on the 20th, and last quarter on the 28th. Image below taken at our observatory. No one was able to identify the crater with the two mountain peaks. Tycho is its name. It was named after the Danish astronomer and scientist Tycho Brahe (1546-1601) who created a remarkable star catalogue of over 1000 stars. This was not the biggest catalogue in the number of stars, but it was quite accurate. His improvement of methods in observations was very significant. He proved that comets are not objects in the atmosphere. He showed irregularities in the moon's orbit. His wall quadrant and other instrument became widely copied and lead to improved stellar instruments. Kepler used Tycho Brahe's observations when he constructed his famous laws of planetary movement. Tycho is one of the most impressive craters on the moon. Tycho is a (relatively) very young crater, with an estimated age of 108 million years, based on analysis of samples of the crater rays recovered during the Apollo 17 mission.The rim of this crater was chosen as the target of the Surveyor 7 mission. The robotic spacecraft safely touched down north of the crater in January 1968. The craft performed chemical measurements of the surface, finding a composition different from the maria. From this one of the main components of the highlands was theorized to be an aluminum-rich mineral. The inside of the crater was also imaged in great detail by the Orbiter V. (See the Home Page for a detailed picture Orbiter took of the rocky plain inside Tycho.)
