Free Logbooks for AL Observing Clubs
These are home-brewed observing logs I whipped up for the Astronomical League’s Galileo, Lunar II, Messier, Binocular Messier, Deep Sky Binocular, Urban Observing, Double Star, and Binocular Double Star clubs. The blank NGC log sheet contains no data, but has fields for everything you need if you’re working on the Herschel 400, Herschel II list, or another NGC-based project. Everything is in PDF format, click on the links below to download it all for free. Don’t worry, the downloadable versions don’t have my name on the cover. Please let me know if you find any errors.
Please note that there are two versions of the Messier logbook: a long one (41 pages) with entries in the same order as the AL list, and a short one (21 pages) with entries arranged following Pennington’s Year-Round Messier Marathon Field Guide. Please be aware that the AL does not accept marathon observations for the Messier Club; the Field Guide order is still a useful progression through the Messiers, at whatever pace. Even the 21-page logbook is probably too cumbersome for a Messier Marathon – for 4-page and 1-page marathon checklists, please see my page of Messier Marathon tools.
Also, I’m making these freely available, with no strings attached. But I have one request: if you use one of these logbooks in completing an AL observing club (or a Messier Marathon), I would be most grateful if you would let me know, either by leaving a comment below or by e-mailing me at email@example.com. (If you’re really grateful, there is an easy, free way for you to support this blog.) Clear skies, and good luck!

Binocular Double Star Logbook (22 pages) Newest logbook, includes coordinates, chart numbers for both Cambridge Double Star Atlas and Pocket Sky Atlas, and a small sketching field for each target. Table of contents lists overlaps with regular Double Star Club and Urban Observing Club.
Binocular_Messier_Logbook_v3 (21 pages) Identical to the Messier Marathon logbook below, but with a binocular-themed title and cover image. New version has coordinates, better data fields, and a table of contents.
Deep_Sky_Binocular_Logbook_v2 (12 pages) Includes coordinates, Pocket Sky Atlas chart numbers, and data fields that are more logically arranged and easier to use. New version has a table of contents.
Double_Star_Logbook (19 pages) Includes coordinates, PSA chart numbers, and a small sketching field for each target. Table of contents lists overlaps with Urban Observing Club.
Galileo_Club_Logbook (9 pages)
Lunar_II_Logbook (49 pages)
Messier_Logbook (41 pages) Original version with big description fields, no chart numbers, and entries arranged following AL list.
Messier_Marathon_Logbook_v3 (21 pages) Slim version with small description fields, chart numbers for three popular atlases, coordinates, and a table of contents.
Urban_Club_Logbook (19 pages) Table of contents shows which objects (80 out of 100!) overlap with Messier list and Deep Sky Binocular list.
Blank NGC log sheet (1 page)
Collinder Catalog v2 (16 pages) This one isn’t my work; as explained here, all I did was convert to PDF form a list that Thomas Watson labored mightily to get into useful form. It also isn’t the subject of an Astro League club, at least not yet. But it’s an observing list and I didn’t have a more convenient place to archive it, so here is goes. Version 2 is based on Watson’s updated observing checklist, which corrects some minor errors in the first version.
Concordiem Australis by RA (4 pages) This one is only barely my work; it’s a merging of the AL Southern Sky Binocular, Southern Sky Telescopic, and Caldwell (56 most southerly) lists, with duplicates removed. The title may seem familiar; it’s an homage to Stephen Saber’s Concordiem Borealis.
Concordiem Australis by Constellation (4 pages) Same as above except for object order.
Finally, for want of any other place to put it, here’s a blank sketching form: Blank sketching form
