Gory na polyuse Luny
Poyasnenie:
Vsya oblast' yuzhnogo polyusa Luny predstavlyaet soboyu dramaticheskuyu kakofoniyu
iz kraterov i pikov. Ekstremal'nye rakursy i ves'ma peresechennaya mestnost' delayut
etu
oblast' ves'ma trudnoi dlya navigacii. I vse eto tol'ko dlya zemnyh nablyudatelei, a
predstav'te, kakie problemy po navigacii vstanut pered staratelyami po dobyche l'da
v budushem! Segodnya u nas velikolepnaya novaya fotografiya obrashennoi k Zemle chasti
pripolyarnoi oblasti Luny. Nachinaya s kratera Moreta (
Moretus),
diametrom v 114 km, i
dalee na yug i nemnogo zapadnee
my
vidim perekryvayushiesya starye kratery s ploskim dnom i dve gory na gorizonte, sredi
vysokih lunnyh pikov. Esli sledovat' nomenklature iz klassicheskoi karty 1954 goda
Yuena Uitakera (Ewen Whitaker) my nablyudaem na perednem plane pik M1, otbrasyvayushii
ten' na krater Kabeo (Cabeus), i M3, nahodyashiisya nemnogo pozadi i vostochnee kratera,
pochti na otmetke v 90° yuzhnoi shiroty. Uitaker predpolozhil, chto M1 vozvyshaetsya
na
20000–25000 futov (6–7,5 km) nad obshem urovnem poverhnosti, a M3 neskol'ko
nizhe i
vozvyshaetsya na vysote v 15000–20000 futov (4,5–6 km). Srazu za polyusom
lezhat eshe
dva dovol'no krupnyh pika — M4 i M5, kotorye podnimayutsya do vysoty primerno
v 30000
futov (9 km) i horosho zametnye pri horoshem osveshenii vo vremya
libracii
Luny. Eti piki nazyvalis' gorami Leibnica (Leibnitz Mts), poka IAU ne uprazdnilo
eto nazvanie
(
prim. perevodchika: seichas na Lune ostalsya tol'ko krater Leibnica). Vse
eti piki
yavlyayutsya chast'yu oboda basseina kratera Eitkena (Aitken) na yuzhnom polyuse Luny —
odnogo iz
krupneishih obrazovanii obratnoi storony Luny, inogda vidimyh s Zemli.

Tehnicheskie detali:
3 September, 2004. One of our first pictures taken with our new 14" f/4,5
Maksutov Newtonian telescope (Observatory Radebeul). We have taken 2000 raw images
with the Philipps ToU-Cam Pro for each of the 2 pictures of the mosaic and added
these raw images at a rate of 4% with Giotto. The 2 resulting images were processed
with Fitswork. To reduce the seeing we used a Schuler IR-Filter. Martin Fielder.
