Observing Targets
2019-04-07
You've got a nice crisp, clear night. You've hauled your equipment to your favourite dark sky site and you're all set for a few hours of observing. What are you going to look at? Astronomers often arm themselves with catalogues such as the Messier List, the Herschel 400 or even the New General Catalog. Astronomy software provides access to these lists and more at your fingertips. For me, I like to have a list of objects that I've either observed, or would like to observe. This is that list! I've sorted the targets by constellation, as that makes the most sense to me (ie: I know what constellations are best positioned for observing on a given night, so I want to see all the interesting targets in them). If you see anything interesting that I might have missed, let me know! Download an Excel copy if you want!
