This is really nice. I'm also having some success with the Star Adventurer and my far more expensive $39 200mm Fujinon lens. Does precise tracking and powerful digital image processing trump great optics?

All important. I think that great optics makes digital image processing a bit easier. You can use Gaussian approximations without bothering to measure real point spread functions. This image doesn't have any deconvolution though. I did step down one stop. Not sure that I needed to, because I just cropped down to the center. I ran out of darkness, but ended up being glad I spent the time on the meteors.
