Lunar 100 resources

Recommended Posts

I thought, given the current interest in the moon, lunar X/V etc that I would post up some info on the Lunar 100.  This is something which I would love to complete, but do struggle with getting the weather/opportunity to coincide with the necessary phases. Must try harder! I need to document the ones I've seen already and move on from there, note to self!

Much of this info is on SGL anyway, I thought I would bring it together in one current thread to highlight it.

http://www.skyandtelescope.com/observing/the-lunar-100/

http://www.astrospider.com/Lunar100list.htm

http://www.salzgeber.at/astro/moon/L100.html

Then of course Doc's wonderfully complete descriptions after he completed the 100 with a 16 inch Lightbridge

One note of caution about the info contained at the end of the OTL100 document. Last night I tried at least to identify the location of Flamsteed P, mentioned as being at it's best on day 10 of the lunar cycle, which I believe was last night. When I checked, it still appeared to be in full shadow so do sanity check this info.

Otherwise, have fun, and do post back how you are getting on.

Good thinking Stu. I’ve not done the Lunar 100 either, but seriously mean to do so in a more concerted effort. Some will prove quite fiendish to see. For instance, in my book 21st Centurt Atlas of the Moon, on the section near Clavius, lunar no;94 is a crater right on the rim of the edge of the moon called Drygalsky (see 1st image below). After I took an image last night of that area I tried to see if I could see it, but due to the libration of the moon is was well out of sight as can be seen in my image from last night too (2nd image below).

Yes, it's surprising just how much effect liberation has and some of these can definitely only be seen at the correct time.

Will see how I get on, stock take of current tally required first, although it would be nice to start afresh.

Great info Stu.

As you say completing the Lunar 100 is quite a challenge, needing to get the libration right to coincide with a clear might.

I've been working on it for a goodly time and seem to be bogged down with a completed count of 85.5, the half is made up from only managing Armstrong from No. 90, haven't managed Aldrin and Collins yet but will keep trying.

Good luck to all of you with this interesting challenge.

Stu would it be useful to make the documents a sticky? If not they will eventually be buried deep in the forum.

Ok, will have a look at this and pull a sticky together. Thanks

Alan, I've done this now.

I've locked the thread so it remains clear, but if anyone has any more documents or links which would be helpful, just pm me and I can add them :)

Thanks for posting Stu. I like the Lunar 100 (only done less then half of it) but would warn anyone just starting on it about some of the odder descriptions, which caused me no end of confusion at first. Don't get put off it you sometimes just can't see what the accompanying text suggests - some of this is heavily summarised "points of interest" that you won't see. The description of Flamsteed P (an ancient crater caused by an impact) is the most confusing I've come across (I had to ask for help on here in fact!). The young volcanic crater it speaks of is not Flamsteed P but a tiny 100m craterlet embedded in it's wall, and well beyond the resolving limit of any amateur scope.

It's a great object list though; I find it gives my lunar observing a bit more structure and direction that it would probably have otherwise.

Billy.

Thanks Billy. I'm considering amending one of the documents to ensure accurate phases for the best time to view, and also additional help to be able to correctly identify the objects, which, as you say, are not always clear; the Schiller-Zuchius basin and Imbrium lava flows being two more!

Flamsteed P has caused me some confusion, I have assumed that it is the large, broken cirular crater outlined in the attached?  There was also a faint inner crater which I could see, concentric to the outer.

I also took Flamstead P to be the large broken structure, the Virtual Moon Atlas appears to agree.

Yep! In my book it is labelled as L68 Flamsteed Ring in square H2 below;

Love this book. I've just been through it and marked all the objects it has in the lunar 100 on the actual map so that I can identify them more easily at the eyepiece.

What is the book? Looks great.

Just looking at another of the descriptions to verify I'm correct. The Schiller-Zuchius Basin is not necessarily easy to work out from the notes. I believe the orange oval is correct, but there is a possibility, I guess, that the shallow basin outlined in red is it?

As per below Stu for title and basin;

Looks great, thanks for that.

I still don't think that makes it totally clear, would you say the orange oval is correct?

The way I see it it is as below, which is near as damn close to your original orange circle you highlighted.

Mick - @Doc did a great job on the Lunar 100 and I think he also produced his own Lunar 200. He did the job when he had his 16" Meade Lightbridge. I must admit that when I go lunar observing I usually look out for libration by viewing this website - https://svs.gsfc.nasa.gov/4605

Once I have established the area I use the book listed above - turn upside down because I only use a Newt now.

My Lunar 100 is nearly complete - Drygalski has caused me a few problems.

Crater Drygalski is very hard even when the moon is at it's greatest libration it's still almost impossible to get a good view.

From my notes I have writtren:

Number 94 Crater Drygalski

Found the crater Casatus with it's two internal craters J & C very easily through the 12.5mm ortho and if I look towards the limb of the moon I could make out craters A. K, and D and in the distance right on the terminator I could see a range of high mountain like objects, which I persume are the 11800 feet wall of the crater Drygalski. I made this asumption mainly due to the fact as Drygalski is the deepest/highest crater between the limb and Casatus so I must have been looking at it's rim.

As you can see I only caught the rim of this crater, I do remember trying a few times to get a better view but it's really hard.

Just read your original posting with the Lunar 100 Mick

Amazing bit of work there.

Its something i must have a go at.

I've just ordered myself a copy of the atlas.

I find the 21st Century Atlas a bit tricky at the eyepiece of a refractor as it is the 'right way round'. However I found a free app for the iPad called QuickFlip which simply flips images - simpler to use than some of the photo editing apps. So, take a pic of the page and flip it on the screen - bingo!

      This is a sticky for resources which can be used to help complete the Lunar 100. They complement the other sticky to Doc's fabulous descriptions from his observations.
      Additional links or material will be added when they are found.
      The following links provide useful material:
      http://www.skyandtelescope.com/observing/the-lunar-100/ - The original April 2004 article by Charles Wood, which started the whole thing off!
      http://www.astrospider.com/Lunar100list.htm - Useful list with images for most targets, co-ordinates and brief description
      http://www.salzgeber.at/astro/moon/L100.html - Another table with descriptions and also links to high quality images
      http://www.shoestringastronomy.com/lunar/lunar100.htm - This link has some useful annotated sketches in the links, not for all targets but quote a few.
      http://www.astrosurf.com/cidadao/moon.htm
      The OTL100.pdf attachment contains some useful info about when is the best phase to observe each target. I've tested some of these and they may be a day out, so use it as a guide rather than absolute fact!

      A beautiful sight greeted me as I walked through the door on the way to work this morning. The Moon was fairly low and illuminated by earthshine. I considered grabbing my 'scope and camera, but didn't have enough time. I wonder how long I'll have to wait before I get another chance at that shot and so can tick L2 off on my Lunar 100 spreadsheet!

      Hi All,
      My GF is the head at a primary school in Lancashire. The school runs various after school clubs/events, such as the MAKE IT club. Some pupils and teachers have expressed an interest in an Astronomy club.
      The question is are there any resources/grants etc. available for primary schools to call on in the Lancashire area.
      She is interested in ideas and resources to support this club. Obviously I have offered myself but I think she is looking for something a bit more formal than a bloke with a scope or 2.
      Any suggestions welcome.
      Thanks in advance...
