略有進步的阿爾卑斯月溪，仍要微調一下後期處理參數，細節會再好一些。當時天文台開了天窗一整晚，望遠鏡主鏡開動了電抽風系統，完全熱平衡了，拍時月亮處於中天最理想位置，所以整體視寧度很好。我很喜歡這相機的2um像素，跟這鏡的f/11焦比很匹配，取樣度絶對足夠。

The slightly improved Alpine Valley Rille, still needs some fine adjustments to the post-processing parameters for better details. At that time, the observatory opened the shutter for the entire night, and the telescope's primary mirror activated its cooling system, achieving complete thermal equilibrium. The moon was in the ideal position at zenith, which resulted in excellent seeing. I really like this camera's 2-micron pixels, match well with the telescope's f/11 focal ratio, ensuring sufficient sampling.
