[Atmob-discuss] Observing the Straight Wall

[Steve Beckwith]

Dear ATMoB Members,

As mentioned in last night's monthly meeting,  the "Straight Wall" on the
Moon, can best be when the moon is eight-days-old.  This is due to the low
sun angle casting a nice dark shadow that highlights the wall. As always,
the key to seeing the Straight Wall is having a clear sky and it appears
that might be the situation for some of us tonight.   

 

Log into the ATMoB website (www.atmob.org <http://www.atmob.org/> ) and link
to the galleries and you'll find posted, an excellent picture of the
Straight Wall taken by John Blomquist.     I've also pasted in a link to a
map that will help you find the Straight Wall in which it is listed under
its official name of  "Rupus Recta".    You'll find it on the right hand
side of Mare Nubium (near the small crater "Bert").   The approximate lunar
latitude and longitude coordinates are -20, 10W.

 

I've always found this a fascinating object and as mentioned last night, my
interest in it was stoked by the wonderful photograph that Tal Mental took
through one of his hand-made reflectors.  He shared it at a club meeting
some  twenty years back when Tri-X and Pan-X were the medium of choice.
It might be interesting to do take images, make drawing or take notes and
then share them via the website or one of the upcoming monthly meetings.  

Good Luck,

- Steve
