Make use of the Moon
« on: December 27, 2017, 11:30:51 AM »
Just a tip for beginners. I know some people don't bother to set a scope up when the Moon is bright. Why not? It may wash out a few faint fuzzies, but not all. Plus it's the Moon! The Moon is one of the most detailed objects we can see. Use it! Throw on a ND filter and pick a spot on it. It's bright so crank up that magnification and start sketching. Just sketch a "small" area. Afterward check a Moon map and identify the features you drew. Next time pick a different spot and do the same thing. After a few sessions pull out your sketches and see how they fit together. You will be amazed how they fit together and that you remember detail names after just a few sessions. Plus its a lot of fun! So next time the Moon is bright break out the scope and sharpen some pencils, then settle in for an enjoyable evening.

There are a lot of double stars, star clusters, and the planets that can be viewed when the moon is up too.

One day, I wanted to know how good my scope was so I tried to find the smallest crater I could
resolve. This involved looking at small craters, finding them on a moon map then getting their name, then using the web to find their diameter. If you want to do this, I recommend looking at small craters at the edge of the seas. That way you can accurately determine what crater you are looking at.
If I remember right, I think I saw a few 4 kilometer craters.

I never paid too much attention to the Moon until a past article brought the "Straight Wall" to my attention. I just had to find it. Only seems to be visible for a few days when it's near the terminator.Interesting that when the Moon is waxing, it's a black line, and when waning, it's white. I have since moved on to the Plato Craterlets. No luck yet. Like the Straight Wall, I guess timing is important. Surely a more difficult target. But, it gets me outside.

Try Virtual Moon Atlas. If you choose to download, please note the updates on the download page.

I've been trying.  At least you can really see the moon, and all your equipment.

There's so much to check out on the moon. Even after 20 yrs I am still finding new things to look at. Vtornado- I'm going to try that. Willie- I was not aware of the color change of the straight wall. Gonna look for that. Thanks for posting y'all.

Another way of "making use" of the moon... I like OLD observing books, and some time back ran across a couple of books by William Frend named "Evening Amusements, or the Beauty of the Heavens Displayed." He put one out every year for quite some time, and these are 1804 and 1805. The text describing the night sky is pretty easy to understand since it obviously changes very little over the centuries. However, when as Mr. Frend puts it, "when the moon comes to our assistance," he uses the moon to describe the positions of the various stars and planets. A reasonable thing to do normally, but when reading the books 212 years later, this gets confusing. I finally solved the problem (with help from others in this forum,) by dialing back the date on Stellarium to the dates and times mentioned in the book and using London as a location to get such things as lunar occultations of the Pleiades to work right.
ANYWAY, this guy used the moon as a pointer in a living planetarium show.

You want a difficult target only briefly visible? Try the rille in the bottom of the Alpen Valley.
It's visible in an 8" (maybe smaller) but only when conditions are *just* so with regard to light.
I've seen it, but never on two consecutive days.

Here is a site for all you lunatics:http://higginsandsons.com/astro/
In case you wanted to see what could be seen on the Moon from the earth.
I believe he uses an 18" scope.

And here is a Lunar Orbiter shot of Tycho's central peak:http://www.nasa.gov/...le_full_0_0.jpg
Note the boulder on the peak and the nearby lines that indicate it once rolled downhill.

Another challenge : Armstrong, Aldrin & Collins. Note that they are approx the size of meteor crater in Arizona.

Alpine Valley? Just found it on my map. Looks interesting. It's now on my list. Thanks!

Currently enjoying Luna using 14"f5.1 dob (coated primary), and Carl Zeiss binoviewer using around 350x, also 25"f3.81 and 33"f4.1 dobs with uncoated primaries. Enjoying craterlets in Clavius and Plato, a 'whole world of experience' in exploring just these two systems. The two larger scopes (when conditions allow-moon at a high altitude, and seeing average and better) exhibit more intricate detail than the 14" (like going from a 12 mega pixel to an 18 mega pixel definition). I really think our 'nearest neighbor' is absolutely an amazing candidate for visual exploration.

Earlier I posted a link to Virtual Moon Atlas. If many of you are unfamiliar with the program, I'm attaching a screenshot. The procedure of finding craters and then searching the web for diameters is really tedious. With Virtual Moon Atlas, life is a lot easier.Attached Thumbnails

Use the moon in the macro sense, perhaps like Frend (mentioned by bumm) did. Allow it to test your true levels of knowledge of the workings of space. Example: we all passed the paper tests on moon phases and their causes. Go outside with naked eye or binos awaiting moon rise at any particular phase. Predict where exactly on the horizon it will appear and its orientation. I'll bet you miss both...

Ask yourself why the moon phases that get marked on civilian maps like new, first quarter, etc are chosen for mention. Let the moon teach you how each named phase can be said to occur at specific minutes that differ each month, even though the moon's appearance changes too slowly to notice without high power viewing along the terminator. (I don't want to give away the answer.)

Let the moon's passage near landmarks like Aldebaran and the Pleaides guide you, again like Frend (gotta find that book...).

Anticipate and plan NOW for where you will be on Monday, Aug 21, 2017 when the moon covers the sun for those fortunate enough or lucky enough to be in the narrow path (approx 70 miles this time) of totality. The spectacle is GUARANTEED to turn even the most DSO-crazed observer into a Luna-loving fool.

(For those of you friends worried about me and my recovery- I just woke up for a snack before going back to bed, taking my wife and dog Cassiopiea with me for a much-needed re-calibration of normal. Good night.)

No moon for me. If you look at that thing too long you become a lunatic. And then, of course, there's the full moon and you know what happens then. No, no, when the moon is out I'm inside watching repeats of I Love Lucy. For your personal safety I sdvise you do the same!

I have more runs during full moon. But I wear a hat so Moon crazy bats don't get tangled in my hair, lay eggs, then I go crazy!!!!!! CRAZY!!!! HAHaHa
