Hi Lee,
Thank you for taking time to share your first impressions with your new telescope.
I am glad that you found optics to be very good, and it looks like you can successfully image with your camera without a flattener (although using one will probably make all stars in the corners perfectly round.).
I hope you will be able to adjust the focuser so it will work reliably. I actually expected that focuser might be potentially the weakest part of this scope, but as you said, it is still too early to say that with certainty.
I will be looking forward to your new, sharper, showing more faint detail and thus more beautiful images
