Dobsonian Telescope: First Light

Tonight was my first night out with my new 10-inch Dobsonian telescope. My first target was The Moon. The scope produced a very sharp image with a 24 mm wide field eyepiece.

My second target was Jupiter. I was able to resolve the four Galilean moons: Io, Europa, Ganymede and Callisto. Also, I could resolve two bands on Jupiter. I switched to a 17 mm eyepiece for a slightly closer look, and the bands were clearer. The view was similar to this image.

The tracking function worked well and kept Jupiter in the field of view. Jupiter was also low in the sky from 9 to 10 PM, and there was some thin cirrus clouds, which would account for the fuzzy periods. Jupiter will be higher later this year.

For my next viewing opportunity I will need for clearer, darker skies to align the Go-To function. Also, I need to try using my reading glasses. Also, I will try my camera attachment, connected to my laptop. I am looking forward to viewing Saturn and Mars.

    Saturn is amazing. I fell off my chair when I first looked at Saturn. I have a 6 inch scope.
