Unguided imaging with 1100 mount

I spent the last 2 nights testing the AP 1100 mount (non-encoder) with unguided imaging of M57. The exposures were 600 seconds, no guiding, with a focal length of 3708mm. Seeing was very good with images of 1.1 to 1.3 arc sec FWHM.

Here is a screen shot of the guider graph and star size of one 10 minute exposure.

Hi Roland - As always, a quality mount. I am going to take this opportunity to go off on a tangent. When is the next batch of telescopes going to be coming out, and will you consider making the 160mm refractor ever again ? I am representing a legion of interested refractor fanatics. Thanks.
