Details:
Venus in fast decreasing crescent phase May 26th 2020 from Tolovana Park Cannon Beach.
A Sony NEX 5R was tripod mounted over a Meade Super Plossl 32mm eyepiece producing 39x magnification, with a Celestron Nexstar 5i Cassegrain with equatorial tracking. The planet was low on the horizon over the ocean through atmosphere and clouds, as the distortions degraded the image considerably.
This near circle of light in seen to be enwraping Venus's circumference, was more so noted as observed in live real time observation through the telescope eyepiece.
*Yet the thin crescent is visible here, but more so the continuous atmospheric lighted circle of Venus' disc this when visible. It is much more difficult to photograph this event than it is to simply observe it, during this very short window of opportunity. To photograph it this must be attempted when the planet is the highest above the Horizon as possible. It is actually more attainable to photograph this event when the planet is still in daylight with the sun still above the horizon. So there are several conditions to be met which are difficult to manage, due to the constraints of the sun's intense light still being above the horizon. This can still be achieved in the next few evenings, but it becomes increasingly difficult as the planet nears the proximity of the sun's direct light in the sky. Needless to mention the dangers which must be advised against. As astronomers we are required to inform the public to never look directly at the sun's disk through concentrated optics, which are not properly filtered to view the sun safely.
The first time I've ever witnessed this. Tonight on May 26th 2020 I'll observe this again, from Portland this time, and possibly allow others to experience this live as observed through the telescope tonight, from a high hilltop somewhere in the Portland metro region.
Technical: Agressive processing was used to render the most details, although this also raised visual noise considerably.
