Today - A study in contrast.
More and more I become aware of the impact of contrast of the sky with the object being observed. Today, I was out in the yard trimming and planting. I looked up and there was the moon. Humm, maybe I can get in some daytime viewing.
Finished with the yard. Around 5 pm I pulled out the Mead ETX 80 for a little daytime viewing of the moon. I have done this before but as I gain experience I notice new things.
The moon is normally so bright that I like to use a moon filter. Today it must have been as bright as usual but the sky was so bright, being daytime, that there was no need for a filter. And I noted that the normally sharp features of the moon were somewhat washed out.
The moon was the same and so was the scope. But the sky was different and the contrast between the moon and the sky was very low so the moon's features were soft and washed out.
Let's just call today's observation "a study in contrast" or lack thereof.
Clear skies to you all.
