前回の金星内合(2017年3月)はお借りした17.8㎝ED屈折望遠鏡で撮像しました。日中の撮像にはS/N比が上がる屈折が有利、無理やり赤道儀に乗せて。晴れた日に必ず撮りました。太陽には接近し弓のように細い金星が素晴らしかった。また金星の背面の円形撮像や、地表模様が検出出来ました。今回は西空が見えず残念!

The previous Venus (March 2017) was imaged with the borrowed 17.8cm ED refracting telescope. Refraction with a high S / N ratio is advantageous for daytime imaging, forcing it on the equatorial mount. I took it on a sunny day. The Venus, which was close to the sun and was thin like a bow, was wonderful. In addition, a circular image of the back of Venus and the ground pattern could be detected. I’m sorry that I couldn’t see the west sky this time!
