Observing The Entire Messier Catalog, But Please….Not In One Night!

The Astronomical League Messier awards certificate book, offers an excellent visual description of each of the entire 110 object Messier catalog, by two very experienced observers.   It includes many pencil sketches as well as some excellent images. The book can be purchased from the AL for only $10.00 plus shipping.  A great buy…indeed! 

Whether you are a beginner or an advanced amateur, this is an excellent book for either. The author’s, Kathy Machin and Sue Wheatley did an excellent job in documenting their observations with detailed notes, plus a lot of supporting information.

I like the following quote from the introduction: “We hope you will not rush through the objects, saying, yep, that’s one. What’s next? The Messier List is not a race.”

I continue to use my copy of the AL Messier Objects even after many years, and actually had the previous edition (the author used a 3.5-SkyScope reflector) before this update version.  Unfortunately, I gave the first edition to someone who I thought would use it, but never did.  I sure wish that I had it back!   Roger

With so many astronomy clubs sponsoring Messier Marathons on the weekend of the 21st, it would be a great opportunity for each club to promote the Astronomical League Messier Awards certificate.

As I’ve mentioned in published articles, emails, and presentations and other:  “Observing with a purpose” is seemingly the most important thing any amateur can do to continue with that passion we all had when we first started.

Glen Chaple quoted me on this in his “Observing Basics” in the March Astronomy Magazine.

What if only two or three amateurs in each of the clubs across the country, sponsoring a marathon would use the night for an opportunity to carefully study each object, making visual notes, and beginning a lifetime of serious amateur astronomy?  I’m betting that the number of serious amateur astronomer’s would increase dramatically!  

Maybe even using the night as a start for achieving their Messier Awards Certificate and pin, and finding their “observing with a purpose”  for many years to come.

M35 and NGC 2158 – Open Clusters In Gemini

FEBRUARY 2015 OBSERVERS CHALLENGE – NGC-2158  

M35 and NGC 2158 have always been favorites of mine.  Years ago when using a 4.5-inch reflector, it could be difficult, especially from my light polluted backyard at that time.  I often used NGC 2158 to determine transparency. 

M35:  102 mm refractor is extremely bright with the most noticeable feature being a curving star chain crossing through the center of the cluster.  The cluster contains mostly bright bluish-white stars.  NGC 2158 appears as a faint, mostly round patch of light without resolution, however, one brighter star (requiring averted vision) can be seen on the western edge.  

NGC 2158:  10-inch reflector at 256x will resolve about 40 or so faint stars.  Excellent seeing and high magnification is required to resolve this beautiful, faint and small open cluster.

The following is a pencil sketch using a No. 2 pencil, blank 5 x 8 note card with a 10-inch reflector at 44x.  Color inverted via computer and standard color sketch…
