Observing Log

This is a good idea.  When I did the H-400, I got a 3 ring binder with plastic sheet covers for AL forms which cost much more than $15 not counting time and effort.


The Herschel 400 Club is meant to be an advanced project for amateur astronomers who already have a fair degree of deep-sky experience. Anyone just starting out should first complete the Astronomical League’s Messier Club before beginning this project.

The Herschel 400 Club
Just Got Easier!

Description: The Astronomer's Herschel 400 Journal is an 8.5x11 inch soft cover, spiral-bound book with many attractive features.

The Herschel 400 Journal consists of 40 log pages containing 10 of the objects on the Herschel 400 List on each page. The Herschel objects are listed in order by NGC number.

Each listing is already filled in with the essential information on each of the 400 Herschel objects listed in the Astronomical League’s Herschel 400 Club. This information includes NGC Number, Right Ascension and Declination, Visual Magnitude, the Type of Object, and the Constellation in which it can be located. Right Ascension and Declination have been updated to Epoch 2000. There is plenty of space in each entry to be filled in by the user with a brief description of the object when it is observed.

Each page is printed on heavyweight paper to minimize “see through” characteristics, contains defined fields of entry, and provides generous space for the observer's notes and additional information on the object.

In addition to the log pages, we have provided three versions of the Herschel 400 list: 1) by Season, 2) by Constellation, and 3) by Tirion Sky Atlas 2000 chart number. In this edition, we have also included Seeing and Transparency tables to help you as you make your observations. There is also a section on Astronomical Note Taking to help you make better observations.

This book will provide you with an easy way to log your Herschel 400 observations, and will make it easy for you to keep track of your progress as you work through the program.

The Astronomer's Herschel 400 Journal is a book that any amateur astronomer pursuing Herschel 400 Club Certification will benefit from. We all know the virtues of writing down what you see and keeping accurate records. The Astronomer's Herschel 400 Journal makes it that much easier to successfully complete the Herschel 400 Club in an organized and economical way.

Clear skies! Good Observing! Fight light pollution!

Essential Tools for Serious Observers

Start Keeping an Observing Log

One thing that I have come to realize in regard to this hobby that we love is that I haven't always developed the good observing habits that I should have. Foremost of the habits I "should have" developed is the practice of keeping a log of my observations. This is one habit that I now intend to develop, because of the huge benefit that this one thing could have done for me as I become more advanced in amateur astronomy. Because I taught myself this hobby from childhood and did not have a mentor to help, I missed out on learning to use this fundamental tool. If I had kept a log all these years, I would have had 35 years worth of notes on all of the objects that I have looked at. What an asset this would have been for my efforts as president of my club, and as contributor to its newsletter. When I write the 'Constellation Close-up' articles, how nice it would be to have such a logbook, rather than just my memory, to rely on. And now that I am supposed to be the "mentor," I find myself encouraging others to do something that I have not done (but I am going to start doing). Therefore, I am going to get a copy of the Astronomer's Herschel 400 Journal to help me start doing just that. Please learn from my mistakes, and don't end up years later regretting that you "should have," like I do now. - DK
