I'm pretty surprised about how well this one came out, considering that the altitude of Saturn was barely 20 degrees.
This photo was created with Plossl eyepiece projection. It seems that there's little difference between using a stock eyepiece and a several times more expensive Barlow lens. As a bonus, the magnification factor can be freely adjusted by changing the distance between the sensor and the eyepiece.
