  1. Lunar and Solar Observing Beginners Astronomy Martin Crow Crayford Manor House Astronomical Society

  2. Last time Visually observing variable stars Meteor watch: What are meteors Visual observation Imaging meteors A look at setting up and using telescopes Martin Crow Crayford Manor House Astronomical Society

  3. This week: Lunar observing using a telescope: Using charts / maps of the Moon Things to look out for Grazing occultations Drawing / sketching Martin Crow Crayford Manor House Astronomical Society

  4. This week: Safe Solar observing using binoculars and a telescope: Do’s and don’ts Ways to observe safely What to see in white light Other ways to view the Sun Martin Crow Crayford Manor House Astronomical Society

  5. Observing the Moon Observing the Moon visually and optically What you will see and what you can do. Martin Crow Crayford Manor House Astronomical Society

  6. Visually Most obvious are the phases of the Moon Martin Crow Crayford Manor House Astronomical Society

  7. Phase Northern Hemisphere Visibility Standard time of culmination (mid-phase) New moon Not visible, traditionally Moon's first visible crescent after sunset 12 noon Waxing crescent moon Right 1–49% visible afternoon and post-dusk 3 pm First quarter moon Right 50% visible afternoon and early night 6 pm Waxing gibbous moon Right 51–99% visible late afternoon and most of night 9 pm Full moon Fully visible sunset to sunrise (all night) 12 midnight Waning gibbous moon Left 51–99% visible most of night and early morning 3 am Third quarter moon Left 50% visible late night and morning 6 am Waning crescent moon Left 1–49% visible pre-dawn and morning 9 am Dark moon Not visible, traditionally Moon's last visible crescent before sunrise 12 noon Martin Crow Crayford Manor House Astronomical Society

  23. Safe Solar observing Do’s and Don'ts Never look directly at the Sun Never look directly at the Sun through unfiltered binoculars and telescopes Never leave equipment pointed at the Sun unattended without covering the object glass / telescope front. Never use eye piece solar filters Martin Crow Crayford Manor House Astronomical Society

  24. Safe Solar observing How to observe the Sun safely Image projection This is by far the cheapest and easiest of the safe methods. This image can be just viewed and shared by a group of people. It can be drawn. Or you can take a picture of it. Martin Crow Crayford Manor House Astronomical Society

  26. Safe Solar observing Martin Crow Crayford Manor House Astronomical Society

  27. Safe Solar observing There are two types: Solar filters for the front end of the telescope: 1. Reflective film – Baaderastro solar Martin Crow Crayford Manor House Astronomical Society

  28. Safe Solar observing There are two types: Solar filters for the front end of the telescope: 2. Reflective coated glass filters – Thousand oaks Martin Crow Crayford Manor House Astronomical Society

  29. Safe Solar observing Solar filters for the rear end of the telescope: Herschel wedge This allows safe viewing of the sun full spectrum in white light. Martin Crow Crayford Manor House Astronomical Society
