Description

It was a lot of fun to work on this series of images. Especially this month (May) was quite busy. Due to bad weather forecast and the altitude of Venus now becoming too low, I will not be able to image further pictures this week. So the series is now done. All tracking was done manually, which was quite painful with such a small camera sensor paired with 3810 mm focal length.

- Explore Scientific 3x focal extender -> 3810 mm focal length

Description: In the new revision, I increased the sharpness a bit using the "multiscale linear transform" process in Pixinsight.
