Rimae Petavius aka Petavius Wall
Two significant rilles on the crater floor.
Observer Comments
| Target Description | Rimae Petavius (aka Petavius Wall) is a system of two major rilles, plus a series of minor ones (The latter invisible in my image). The largest rille connects the wall of the crater to its central mountain complex. The two major rilles are just visible in my capture when I adjust the gamma. It's unfortunate I couldn't have used my EdgeHD (for reasons explained) as I undoubtedly would have imaged a clearer view of them. |
| Image Capture Description | This capture took place on the same evening as the conjunction of the crescent moon with the Pleiades (M45). So this image was taken "between" stacking of this cluster as part of one of the optional exercises in this program. The good news is that I had time to use the real-time lucky imaging and wavelet sharpening built into SharpCap. The bad news is that I could only use the Askar V configured with reducer to 384mm focal length, in order to be able to image all of M45 and the moon in the same frame. All that said, it is a useful image and substantially better than the Seestar would have delivered. |
