Lunar Features
Produce a series of telescopic drawings and/or photographs of three lunar surface features.
Use them to show their changing appearance at different lunar phases.

Meteor Shower Photography
Use long-exposure photography to obtain photographs of a meteor shower.
Estimate magnitudes of the meteors. Locate and show the position of the radiant.

Photographs of Lunar or Solar Eclipse
Using a suitable method of observation (lunar — direct, solar — projection), produce a series of photographs showing the progress of a lunar or solar eclipse.

Constellation Photography
Produce photographs of three different constellations, recording dates, times, seeing and weather conditions. Use the photographs to identify colours and magnitudes by comparison with reference stars.

Telescopic Drawings or Photographs of Celestial Event
Produce a series of detailed telescopic drawings or photographs to record the passage of a suitable celestial event, for example a transit, occultation or comet.

Sundial
On at least three widely-spaced dates, compare the time shown on a correctly-aligned sundial with local mean time. Use these data to determine the accuracy of the sundial used.

Photographic Measurement of Levels of Light Pollution
Use the magnitudes of the faintest stars visible in long exposure photographs to quantify the effect of light pollution at two different sites.

Sunspots
Use a small telescope to project an image of the Sun onto a suitable background and observe and record sunspots over a sufficiently long period of time to determine the Sun’s rotation period.

Light Curve of a Variable Star
Use a series of telescopic estimates of the magnitude of a suitable variable star over a sufficient period of time to determine the period of the star.

Measuring Stellar Density
Use binocular/telescopic observations or original photographs to measure and compare the density of stars in the sky, parallel with and perpendicular to the plane of the Milky Way.

Drawings of Messier Objects
Use binoculars/telescope/robotic telescope to produce detailed drawings and/or photographs of at least three Messier/NGC objects.

Measuring the Sidereal Day
Take long-exposure photographs of the circumpolar stars around Polaris or the south celestial pole and use them to determine the length of the sidereal day.
