M101 Test Image

This is a 60 second individual exposure of M101 at ISO600 with a 3x barlow screwed onto the nosepiece of my camera adapter giving me about 2.25x magnification and putting my 130p-ds at 1,462.5mm and f11.5. A lot of field curvature can be seen in this image due to the cheap svbony barlow.
