Waiting on the Sun

Image
I am all set up to do some solar imaging but I am now waiting for the sun to clear the trees.  This time of year, the sun travels very low across the sky so I only have a relatively short window of opportunity to observe or view the sun.   I plan to start with some white light observing and imaging of the sun's photosphere.  My solar wedge solar filter includes a Continuum filter as well as the usual IR/UV Cut, Neutral Density and Polarizing filters which has always worked fairly well for me.  I've observed and imaged this way before so there is nothing new with this configuration.  I plan to do something new today too though.  I now have a narrowband 3nm Calcium K filter inside a different solar wedge filter that I have yet to try so that will be part of today's plan.  This should produce nicer results.   The one "different" thing about this filter is that this Calcium K filter is not an observing filter.  Actually, my eyes should see nothing through this filter.

Solar System Observing

A fter a mostly sleepless night the night before last with some health issues that kept me in the bathroom and seriously cut into my sleep, I managed to get some sleep yesterday afternoon for about three or four hours in preparation of a clear night last night.  Clear nights around here are few and far between any time of year but especially in the November through March timeframe so I don't like to waste these rare nights, if possible.  This meant a relatively rare opportunity for viewing some objects in our solar system.   As the sky darkened to a deep dark blue, I set up a new telescope of mine that I have been evaluating as an option for beginners.  I had three eyepieces on hand;  a low power wide eyepiece, a medium power eyepiece, and a high power eyepiece.  I also had my Sony a6000 camera ready to go with a nosepiece on it so I could slide the camera into the diagonal in place of an eyepiece when I felt the view was worthy of recording.  Facing the back end of our backyard in
