IWLOP #135 - Lacroix & Southwestern Limb Region

Observation 1:
Location: Home
Date: 2025-10-04
Time: 10:35 PM ADT
Equipment: 10” Meade SCT
Eyepiece: 10mm (SvBony 10-30mm Zoom Eyepiece) + x2 Barlow
Magnification: x500
Seeing: Very Good (2)
Transparency: Excellent (1)

R1: Lacroix was very small but seen well despite the slight turbulence. Numerous irregular-shaped craters in the area. Lacroix J seemed deeper, certainly smaller and obviously was formed later as it impacted the Lacroix wall. The crater Piazzi was an interesting one nearby.
R2: The numerous craters in the area seem to be infilled, appearing smooth on their crater floors and some even had degraded walls.

No wind but high thin clouds from time to time affected the ability to see details.

C1: It took a while to locate the crater Inghirami and a while later to identify Vallis Inghirami. The crater appeared elongated, and had a strange structure on its wall; not sure if it was an impact crater or an area created from slumping. Its central peak was slightly off centre. Then I noticed a long, flat area going north from the crater that was almost the full width of the crater.  Initially, there was no wall near the crater but as the Valley went further away, the walls became steeper and terminated in high-walled point containing a impact crater, creating a shaded area (refer to sketch).
     Vallis Baade also took a while to locate in the rugged terrain adjacent to Inghirami. The Valley, very much thinner than Vallis Inghirami, was almost parallel from beside the crater to almost the end of Vallis Inghirami.
