That's coming along nicely Kevin. When I looked at your field of view I thought it was going to be a 4 inch scope or something similar. I too have an Esprit 100 and my shot of M83 looks much the same but I use a DSLR. Focus can be a tricky one with a refractor, a little bit out either forward or backward of the sweet spot can be hard to judge at times. Yours may not be a focus issue but just due to seeing conditions at the time of exposure. As for Alex's stray light baffles, a stubby holder over a camera lens works for me!
