Dave Manifold's LX-50 and ST-80 Astrophotography Gallery My Meade LX 50 10" Telescope (with home made dew shield). This picture of my Meade LX 50 10 inch telescope should give you an idea of what I am using to take these photographs. I took this photograph on 3/12/99 at Lemon Lake in Cedar Lake Indiana. The sun was just setting in the background and a blanket of snow was covering the ground. Several of the photographs on this page were taken with this telescope and guided with the Meade ETX 90 , others were taken with the Orion Short Tube 80mm Refracting Telescope and guided with the LX 50. You can click on any of the thumb nail pictures to get the full size scan. I have tried to keep the scans at their original size but, a little variation in actual size has been noted. Click here for more information on the Meade LX-50 Telescope The camera that I use is the Minolta Maxxum 7000i SLR. All of these photographs have been edited in either Corel Photopaint 5.0 Microsoft Photodraw 2000 Picture Windows or combination of the three. Moon.jpg

Telescopes Chapter index in this window Chapter index in separate window This material (including images) is . See my for fair use practices. Men and women have looked up at the sky and wondered about the things they see up there for as long as humans have lived on our Earth. Long ago, the Sun and Moon were mysterious objects that could be seen in the day and night. But the planets and stars were even more mysterious probably because they are so far away that we could only see them as points of light. Unlike the things on the Earth that we can study up close, handle, listen to, smell, and taste, the only thing ancient watchers of the sky had to learn about things in space was their eyes and imaginations. Only very recently in the history of humanity have astronomers been able to extend the reach of our eyes (and our imaginations!). Galileo pioneered modern explorations in the early 1600's by using a device originally invented for naval operations to explore the heavens. The device he used, of course, was the telescope , an instrument used to gather and focus light. Our atmosphere prevents most of the electromagnetic radiation from reaching the ground, allowing just the visible band, parts of the radio band, and small fractions of the infrared and ultraviolet through. Our eyes can detect the visible (optical) band, so the early telescopes were all built to observe in that part of the electromagnetic spectrum. It wasn't until the 1930's that astronomers began observing with another part of the electromagnetic spectrum-the radio band. The development of space technology has enabled astronomers to put telescopes above the atmosphere and explore all of those places out there using the full range of the electromagnetic spectrum. This chapter covers the basics of telescopes and the effects of the atmosphere on images. Vocabulary terms are in

The Catalogs and Surveys Branch (CASB) is digitizing the photographic plates to support HST observing programs but also as a service to the astronomical community. The 6.5-degree x 6.5-degree plates are scanned using a modified PDS microdensitometer to a pixel scale of about 1.7 arcseconds per pixel for the POSS, SERC, and Palomar Quick-V surveys, and to about 1.0 arcseconds per pixel for the POSS-II surveys.

Telescopes This set of notes by Nick Strobel covers: the basics of telescopes and effects of the atmosphere on images. Vocabulary terms are italicized. Contents Types of telescopes Definition of telescope. Refractor Reflector Powers of a telecope Light Gathering Power ... Atmospheric lines Types of Telescopes Index Telescopes instruments used to gather and focus light. Visible and large parts of radio spectrum can be observed anywhere on ground; small parts of infrared (IR) must be observed above water layer in atmosphere (elevations of 2750 m (9000 ft) or above); gamma-rays, X-rays, UV, most IR, and rest of radio must be observed in space. The part collecting the light is called the objective. Refracting Telescopes Index Refractor use lens to bend light. First ones built. Disadvantages: a) Chromatic Aberration redder colors bent less than blue colors so see rainbow of colors around the image. Use multiple compensating lenses to counteract this OR have really long objective focal length to minimize effect (see drawing). This is why the early refracting telescopes were made very long. b) Support for lens only at ends of lens. Tends to sag under own weight. 40 inches is maximum size of refracting objective built. Reflecting Telescopes Index Reflector use mirror to reflect light. All modern research ones are this type. Advantages: a) No chromatic aberration. b) Support for objective all along one side so they can be BIG! Parabollic-shaped mirror focuses all parallel light rays to single point (remember that celestial objects are so far away that all the light rays from an object hit the Earth as parallel rays). Focus is before the eyepiece, so the image in astronomical telescopes (even with the refractor above) is upside down. Terrestrial-viewing telescopes use other lenses to re-invert the image right-side up.

Intro Welcome to Stargazers, an unofficial website for British rock band, The Telescopes and Unisex. The Telescopes are back after a 9 year hiatus and in celebration of that I've decided to create this website, something I've always wanted to do but just never got around to it until now. So i thought with news of a third album, the time would be perfect to start this site. Members of The Telescopes also record as Unisex. I'm hoping this site will be an excellent resource for this underappreciated band. Quotes about the band "Every sound you've ever heard was but a preliminary excercise for the all-embracing maelstrom of The Telescopes" (Melody Maker, 1989) "Like mad cultural terrorists, they've taken the norm and fed it through a psychedelic blender. It's all rather jagged and unsettling, the musical equivalent of cackling maggots spilling out through the eyeholes of the beautiful- and is both timely and exciting" (Melody Maker, 1994) Site info Online since: February 10, 2002.

More than 2100 people attended the meeting from 27 countries. Highlights included 27 conferences, four large poster sessions, and seven renowned plenary speakers. For each plenary session, the audience filled the ballroom to capacity and spilled over into the overflow room that provided video and audio of the speakers. The exhibit included 38 companies who were very happy to have an interested and rather "captive" audience throughout the week. A large crowd gathered for the Welcome Reception on Friday evening.
