The Inner Planets - 22nd December 2018

Technical card

Resolution: 2480x1564

Locations: Home property, Wattle Flat, NSW, Australia

Data source: Backyard

Description

I had quite good seeing to image both Venus and Mercury this morning. I set this image to their relative actual scale. Mercury would have to be about half the size of Venus in this image to be to scale in a telescope eyepiece.

The Venus image is an RGB capture and there is some subtle banding. This was more visible in UV, but comes through to a certain extent in the blue channel and thence to the RGB composite. The planet has an apparent diameter of 29.9 arc secs and is 41.2% illuminated.

The Mercury image shows more surface features than my previous image, including some dark craters near the terminator. Mercury is now only 5.9 arc secs in apparent diameter and 77% illuminated.
