Används för luminansbilder med reflektorsystem (t.ex. RC-teleskop) och för fokusering i kombination med smalbandsfilter...Baader 31 mm CCD klarglasfilter - IR pass Långtidsexponering med spegelteleskop utan korrektor Vid astrofoto är det oftast nödvändigt att använda ett IR blockfilter, då linser eller korrektorer inte är korrigerade för infrarött ljus. Skärpan försämras då också radikalt. CCD chipen är känsliga även in i det infraröda området. I renodlade spegelsystem, utan korrektorlinser, kan därför även det infraröda ljuset utnyttjas och det betyder ca 15% mera ljus, vid jämförelse med system som använder IR blockfilter. Fokusering smalbandsfilter Detta filter har samma filtertjocklek som andra Baaderfilter och är avsett för luminanskanalen vid astrofoto. Fullt ut parfokalt med Baaders smalbandsfilter. Fokusera därför med klarglasfiltret och skifta sedan till önskat smalbandsfilter utan förändring av fokus. Detta är en stor fördel då smalbandsfiltren har ett litet ljusgenomsläpp, som ofta försvårar fokuseringen. Manual och informationsblad till astronomiska filter ()

This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments. Have you ever been on the beach at night, watching the sky overhead, and seen streaks of light against the background of stars? Though many people still refer to these as shooting stars, they are, of course, not stars. They are meteors—small chunks of rock and ice debris from disintegrating comets that are careening through our Solar System and sometimes enter Earth’s atmosphere. Most are so small that they burn up as they enter the atmosphere. These are called meteors. In a meteor shower, many meteors can be seen streaking across the sky in a short time. A few meteors make it through intact and descend to Earth as meteorites. Watching these beautiful streaks of light in the sky can be an exciting pastime, and it can result in some important science. Robert Lunsford explains what meteors are, where they come from, and what happens to them as they whiz through space and enter our atmosphere. He tells how to observe meteors and meteor showers, what equipment to use, what you should look for, where you should look, and much more. Armed with the information in this book and with very little effort and equipment, you can begin your regular search of the heavens right now and join the ranks of those who have made this rewarding pastime a lifetime hobby.

In this book, Warren Keller reveals the secrets of astro-image processing software PixInsight in a practical and easy to follow manner, allowing the reader to produce stunning astrophotographs from even mediocre data.Inside Pixinsight av Warren A. Keller As the first comprehensive post-processing platform to be created by astro-imagers for astro-imagers, it has for many, replaced the generic graphics editors as the software of choice. With clear instructions from Keller, astrophotographers can get the most from its tools to create amazing images. Capable of complex post-processing routines, PixInsight is also an advanced pre-processing software, through which astrophotographers calibrate and stack their exposures into completed master files. Although it is extremely powerful, PixInsight has been inadequately documented in print--until now. With screenshots to help illustrate the process, it is a vital guide.

This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child.Astronomy for Older Eyes Author: James L. Chen, Adam (ILT) Chen, James L. Chen Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth, meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20/20 eyesight has given way to reading glasses or bifocals. Treasured eyepieces feel all wrong. Growing old is a natural process of life, but astronomy is timeless.With a little knowledge and some lifestyle adjustments, older astronomers can still enjoy backyard observing well into their seventies, eighties and even into their nineties.
