Meade ETX-80 Images from Winter Park Colorado
Post date: Feb 27, 2014 1:32:26 AM
I was on vacation in Winter Park, CO with my family and took several images through my Meade ETX-80 (400mm EFL, F/5) using a Nikon D5200 camera. The conditions were partly cloudy with occasional gusty winds at 0C. The skies were dark enough to see the winter Milky Way and M44 by eye. The images are unfortunately not focused well, but I was pleased that the very compact little telescope could produce reasonable results. To take the images, I attached the ETX-80 on a modified LX-90 wedge, and bolted the wedge to the ETX-80 field tripod.
Because the images are un-guided, and because of the wind, I used high ISO settings to keep exposure times short.
