Recently while browsing Chuck Woods recent LPODs, I noticed he has assigned an informal name to the western rim of Mare Crisium near C. Swift - the Wasatch Mountains. Wood's description is: "Although basins are the biggest impact features on the Moon, on the nearside we get to see relatively fresh rim segments only at the Altai and Apennine mountains. At other basins the rims are much reduced in height or virtually gone altogether. . . . The [Crisium] main rim  which lacks a name so I henceforth call them the Wasatch Mts  rises 5.4 km above the nearby Mare Crisium west of Yerkes and 5.0 km above the mare west of Swift (Peirce B)." Wood, C.A. 2/3/2006. Sunset on the Wasatch Mountains. LPOD http://www.lpod.org/?m=20060203 Crater Swift is 10 km diameter crater at 19.3N 53.4E. See Rukl Chart 23. - Canopus56 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
Hopefully the IAU will agree with Wood. Catchy name. --- Canopus56 <canopus56@yahoo.com> wrote:

Chuck, sometime ago you mentioned that you were studying Solidworks. I don't know if this is the same software, but this LPOD features an amateur astrophotographer using Solidoworks to produce a flat image of the lunar limb: http://www.lpod.org/?m=20060317 - Canopus56 __________________________________________________ Do You Yahoo!?

I got my Solidworks certification last fall, and yes it does appear to be the same 3D program. "Flat" isn't really the best descriptor, "non-foreshortened" is closer to the mark. The low-tech approach that we used 30+ years ago, and it produces results almost as good as the Solidworks modeling, is to project the limb image onto a tilted surface, to compensate for the foreshortening. If using a lens with a sufficiently-long focal ratio, the difference in focus along the tilted surface is minimal. It could be done with a slide projector, or an enlarger for a printed copy. I think Patrick showed me this technique, but memory is sketchy on that detail. Thanks for that link, very interesting! --- Canopus56 <canopus56@yahoo.com> wrote:
