Here are the images: 15 seconds at 2000 ISO with 10mm eyepiece and eyepiece projection. Sirius B is the ragged streak hard up on the left hand side of Sirius. You will see that it is really there because the squiggle of the streak is different in each image and matches the other stars confirming that it is Sirius B. I have since ‘trained’ my drive and hope to do better next time. I have also included an image of the refractor, one of the common, garden variety, cheapie 150mm F8’s.
