Lunar Eclipse 2019

This event just happens to correspond to first light with my new telescope, the Astro-Tech AT115 EDT refractor.  The first picture is through optical tube with the iPhone and the second is using a Canon T3i/600D modified.  The performance of the telescope is incredible.  I have never seen the the moon as sharp through the eyepiece.   In fact this is one of the few objects that despite all of the incredible and wonderful images that people have taken of the lunar eclipse, I like the eyepiece view the best.

The iPhone picture had no processing done on it and the DSLR image had very little - just a crop, a slight curve, and a bit lowering the red, but that is it.

Part 2
The second part of imaging the eclipse for me was getting a larger star field with a camera lens to combine with the detailed view of the eclipse. It would be cool to get this in one shot but it is quite unlikely as imaging stars blows out the moon so you have to combine it with a second lower exposure image.

The wide field image shows the bright star Pollux in the upper left side of the image and the Beehive Cluster (Praesepe or M44) on the middle bottom of the image.
