阴天了三个月最近转晴,刚刚的週日真够累,午夜前用EdgeHD 14 + Hyperstar用冷冻相机拍深空,到黎明时则换上原来的副镜及另一个相机拍月面,最后一段影像完成时,其实离日出已不足半小时,天空都已鱼肚白了。这次算是满意,那条寛度不足1公里的阿尔卑斯月谷中央月溪都清晰拍下来了(https://the-moon.us/wiki/Alpine_Valley_Central_Rille),而直壁旁的伯特溪(https://www.skyatnightmagazine.com/astrophotography/moon/rupes-recta-straight-wall/)对今天的器材来说则是轻鬆目标,但已故的香港太空馆创馆馆长廖兴齐先生于1971年时用他的12吋卡反因为清晰拍下这条月溪而获得世界冠军。拍下弦月的好处是视宁度较好,但代价是很累。以下影像只作初步处理,稍后会再进一步处理出图。
It has been cloudy for three months, but it has been turned clear recently. Last Sunday was really tiring. Before midnight I used the EdgeHD 14 telescope with a Hyperstar and a cooled camera to image deep space. Then as dawn approached, I switched to the original secondary mirror and another camera to image the moon. By the time I finished the last video shot, there was less than half an hour until sunrise and the sky was already turning bright. I'm satisfied with the results this time. Even the Alpine Valley Central Rille (https://the-moon.us/wiki/Alpine_Valley_Central_Rille), which is less than 1 kilometer wide, was captured clearly in the image. On the other hand, the Rima Birt (https://www.skyatnightmagazine.com/astrophotography/moon/rupes-recta-straight-wall/) next to the Rupes Recta was an easy target for today's equipment, but the late Mr. Joseph Liu, the founding director of the Hong Kong Space Museum, won a world championship in 1971 by capturing a clear image of this lunar feature using his 12-inch Cassegrain telescope. The benefit of imaging the 3rd quarter moon is that the seeing is better, but the problem is that it's very tiring. The following images are only preliminarily processed, and will be further processed into final versions later.
