In so doing, they corrected many of Herschel's recording errors. All of those errors went into the New General Catalog, and there have been many attempts through the years to correct them.
Fortunately, Herschel and his son were consummate writers, where descriptions were concerned.
So, the question I have is: "Did Bratton use the corrected positions to identify and view the Herschel objects, or did he simply skip over the hundreds of objects with mis-plotted locations?" Because a text that has all 2500+ Herschel objects without those corrections would, while historical, not be as valuable to the observer.
After all, the Herschels themselves would want any errors they made to be corrected, as any meticulous observer would.

That makes this an exciting book!

And regarding the NGC/IC corrections - there are many objects that will remain lost and many that people will have different opinions about. For example in some of the cases the modern corrections made by Wolfgang Steinicke surpass those of the NGC/IC project.

I'll stop there. If I stated 0 sketches it doesn't mean there aren't images and of course there are plenty of images in each constellation.
The quality of the sketches aren't bad, it just seems they lost some of the translation in the printing process. Jake S. I think you'll find them ok, as they reminded me of some of your sketches and some of your fellow observers/sketchers up in Finland. I have to admit that when I spent some time going through my copy in many ways I thought of the NGC/IC project and that it duplicates that though replacing Steve G. with Mark B.'s observations. Am I glad I got it? Yes, its a nice reference for the shelf or desk. Am I happier it was a gift? Yes, as I think there are some other book I am glad I purchased around the same time first.
One thing that is missing in a Herschel Project is not perhaps including sketches in a book, but having the references and then granting access to a website that has a lot or many sketches of the H400 or the H2500. That though is a tremendous task to undertake. It is fun though.
I do like O'Meara's book but in the end, as I finished the H400 and am doing the H400 II I am finding as many have, that the best thing is to observe it on my own, to figure out my own finder chart and to enjoy the experience myself. I enjoy the books, and they add enjoyment during those cloudy nights, but nothing beats going out and bagging these items myself. I think that is what Bratton's book does, it provides some motivation to go out and observe and then compare one's observation with his and others. His enthusiasm comes through in his descriptions and that is also another plus, one gets to see how someone else views these objects and their enjoyment. For me, I have enjoyed his descriptions most of all.
