NB75 (NASTRO Binocular 75) Observing Challenge
The NB75 is an observing challenge for beginners. The list of objects - star clusters, nebulae, galaxies and more - are graded from easy to very challenging. They are all visible from Northumberland with binoculars (and in many cases - with no optical aid).
The complete list with details for each object is given in the Excel spreadsheet below.
Here are the lecture notes (PDF) from Adrian Jannetta's introductory talk about the NB75 challenge at NASTRO on July 28th 2021:
