level 3 – advanced list

Welcome to the OSP Advanced Observing List

In a sincere attempt to lure more of you to try the Advanced List, each object has a page telling you what it is, why it’s interesting to observe, and the minimum size telescope you might need to see it. I’ve included coordinates, the constellation each object is located in, and a photo showing what the object looks like. All you have to do is observe and enjoy the challenge.

Stretch your skill and imagination – see something new, something unimaginably old, something unexpected

  • Even though this is a challenging list, you don’t need 20 years of observing experience or a 20 inch telescope to be successful – although in some cases that will help. The only way to see these cool objects for yourself is to give them a go.
  • The minimum aperture listed for each object is a rough estimate. The idea is to show approximately what size telescope might be needed to successfully observe that particular object. The range is 4 to 18 inches this year.
  • The visibility of each object assumes decently good OSP observing conditions.

Requirements to receive a certificate

  1. There are 14 objects to choose from. Descriptive notes and/or sketches that clearly show you observed 10 objects are needed to receive the observing certificate. For instance, you can mark up these photos and charts with lines and arrows, and add a few notes describing what you saw. Or make a sketch on the back of each page, and add a few notes. Or go with whatever method you normally record your observations.
  2. You must meet the stated “Criteria for successful observation” for the 10 objects you choose. Simply noting that you saw the objects doesn’t count.
  3. Observers who successfully observe 10 objects also qualify to purchase a cool observing pin. Bring your record of observations to the Observing Program table next to the Information Tent to receive your pin.  The Observing Program table will be staffed by volunteers 2-4 PM Thursday, 1-3 Friday & Saturday, 10-12 Sunday.
