It might be said that there are as many good websites as there are stars.

Richard Dibon-Smith Website

This one has not been maintained in about five years. I stumbled upon it while looking for information about binaries.
Shortly after it was launched in 1995, Richard Dibon-Smith's CONSTELLATIONS website won a mention from the Griffith Observatory for its fine work.

It seems to have started out as a guide to constellations with folklore, maps, etc. However, it grew beyond that. Among the tools I found is a key to the abbreviations of discoverers in the Washington Double Star Catalog. It is under the Binary Database: http://www.dibonsmith.com/bin_data.htm
His Messier and NGC Lists are tied directly to the constellations with their folklore. So, they may not be convenient if you are chasing those. On the other hand, it does make a convenient guide for the beginner looking for Deep Sky Objects and not relying on a computerized drive. The Table of 150 Binaries with their separations could be a help.

The Star Data Tables (http://www.dibonsmith.com/data.htm ) are, again, organized by constellation. Within that you will find the Hipparcos catalog number, magnitude, distance, parallax, and a graphic of the binary's orbit. (if one is available).

All in all I found this to be a noteworthy effort. I bookmarked it as an aide in targetting binaries.

Thank you Mike! I saved it in my phone!
I especially like the graphic images. So many times when chasing doubles, I look in the lense, rub my chin and mark it off as a “maybe.”

That really is a fact filled web site!

Saved to bookmarks.

Thanks Mike.

haha! I just ran across this post and remember hearing about this guy a few years back. Just make sure you don't use any of his stuff without permission. Check out this part of his site. http://www.dibonsmith.com/plagiarists.htm

One of my favorites is Telescopius, whose creator I believe is one of our vendors.

Here are a few references that I've utilized at various times, in no particular order. I also utilize Telescopius as Michael mentioned.

Check out Fourmilab: https://fourmilab.ch/

Lots of astronomy resources there, like: https://fourmilab.ch/yoursky/

It's mixed in with hundreds of other programming, scientific, and linguistic projects of the author. The owner of the site is the co-author of an extremely valuable piece of software in engineering, known as "AutoCAD" which has been a cornerstone of technical drawing for about 30 years.

Here are some valuable resources from Larry McNish. I consult them when planning an evening observing session.
