Hi
Three more images from the weekend of Lunacy!
Details are from Virtual Moon Atlas at http://www.astrosurf.com/avl/UK_index.html an excellent and free Lunar software tool.
PHILOLAUS - Crater
Geological period: Copernician (From -1.1 billions years to present days)
Dimension: 73x73Km; Height: 3400m; Height/Width ratio: 0.0479
Circular formation. Pretty steep slopes supporting Anaximenes G to the North-West, Philolaus C to the
South-West and the large crater Philolaus D to the North-East. High walls in terraces. Flat floor. Two symmetrical and separated mountains.
Longitude: 32.4° West
Latitude: 72.1° North
Quadrant: North-West
Name Origin: Philolaos, a 6th century BC Greek Astronomer and doctor.
GASSENDI - Walled plain
Geological period: Nectarian (From -3.92 billions years to -3.85 billions years)
Dimension: 114x114Km ; Height: 0; Height/Width ratio: 0,0169
Circular formation situated on the North bank of Mare Humorum. Steep slopes to the North gobbled to the South in Mare Humorum and supporting the couple Gassendi A and B to the North. Walls higher to the West and gobbled to the South in Mare Humorum. Very large flat floor covered by Rimae Gassendi. Internal mountainous ring. Double central mountain 1200 m high. Hills craterlets and lines of crest.
Longitude: 39.9° West
Latitude: 17.5° South
Quadrant: South-West
Area: Mare Humorum region
Name Origin: Pierre Gassend (or Gassendi) a 17th century French Philosopher and astronomer.
CLAVIUS - Walled plain
Geological period: Typical Nectarian (From -3.92 billions years to -3.85 billions years)
Dimension: 231x231Km; Height: 0; Height/Width ratio: 0,0204
Damaged circular formation. Steep slopes riddled supporting crater Blancanus to the South-West.
Very high walls ridden by Porter to the North-East Rutherford to the South-East Clavius K to the South-West and Clavius L to the West. Large flat floor with Clavius D C N J & JA on an arc of circle. Numerous craterlets whose a chain to the South-West. Lines of crests.
Position:
Longitude: 14.4° West
Latitude: 58.4° South
Quadrant: South-West
Area: Moon South limb
Name Origin: Christoph Klau (or Christophorus Clavius) a 16th century German Mathematician and astronomer.
Equipment used was my Vixen 4" f9 refractor, TeleVue x5 Powermate and Meade LPI. Due to the image drifting across the filed of view, I was unable to stack more than 20 or 30 images and the seeing was not quite up to the x5 barlow, so the results are a little noisy. The LPI sure is an easy imager to use for objects as bright as the Moon and the capture software is quite useful and competent.
Cheers
