1. Image the entire solar disk showing sunspots with a white light filter OR a hydrogen-alpha telescope. [One image]<\/h4>\n\n\n\n
\"\"<\/figure>\n\n\n\n

For solar and lunar, no<\/strong><\/em>rth is up east to left<\/em><\/strong><\/h4>\n\n\n\n

2. Image and label solar details mentioned in either the Astronomical League\u2019s Sunspotter Observing Program (white light with a suitable filter) or the Astronomical League\u2019s Hydrogen-Alpha Observing Program. [One image]<\/h4>\n\n\n\n

3. Image the entire lunar disk.  Depending on your equipment a mosaic may be required to capture the entire disk.   [One image]<\/h4>\n\n\n\n
\"\"<\/figure>\n\n\n\n

4. Image in detail any seven of the lunar features mentioned in either the Astronomical League\u2019s Lunar or Lunar II Observing Programs. One of the images should show both a crater and a dome. While an image may have several features, seven images must be submitted, each highlighting a particular feature. [Seven images]<\/h4>\n\n\n\n

5. As the terminator sweeps across the Moon\u2019s surface the changing light and shadows can create interesting temporary shapes like the Lunar-X or Lunar-V. These are called Clair-lunar effects. Image the Lunar-X and Lunar-V. The final product may be either a single image or a time-lapse video (AVI, SER, etc.) of the event. [Two images]<\/h4>\n\n\n\n

6. Image Saturn, Mars and Venus (pick two of the three). Saturn should show detail as should Mars if imaged near opposition. Venus goes through phases and may not appear round. [Two images]. Blue arrow is north, gold is east.<\/h4>\n\n\n\n

8. Image Jupiter showing a satellite transit, an occultation, an eclipse, and a shadow transit.   Be sure to include the name of the satellite and event.  Images with multiple events are permissible and even encouraged.  [5 for 3 images]<\/h4>\n\n\n\n
