Another escarpment. This one famous because it cuts a straight line!
Observer Comments
| Target Description | What's there to say? "Yep, it sure is straight!" The fault has a length of 110 km -- roughly 1/4 the length of Rupes Altai. It's typically 2–3 km wide, and 240–300 meters high. It appears to be a vertical cliff but in fact delivers a relatively shallow grade. |
| Image Capture Description | Technically, this is the best lunar observation in this submission (at least so far). It takes advantage of the EdgeHD at full 2032mm focal length and 294 camera. This was my first experience with SharpCap's real-time lucky imaging. I had turned to it out of desperation because wildfire smoke had ruined multiple observing nights for much of the summer. Smoke turned the original image bright yellow (I converted it to grayscale). Despite the poor transparency, the combination of much longer focal length, lucky-image stacking, and wavelet sharpening delivers a much more detailed image than any of the Seestar captures. |
