| Comment : | This photo is taken with my earlier Canon 5D camera, a bit noisier but otherwise not too bad. But one problem and that is I have a lot of dust and dirt on the sensor. I still have very big problem to keep the sensor clean. |

| Comment : | This is the oldest photo I have on the M106 galaxy. It was taken with a big camera lens, a Pentax 500 mm f/4.5. Compare this lens with the new TS APO triple lens with field flattener. The new one has much better color handling and almost no vignetting (on full frame sensor) which was heavy on this Pentax lens. |
