Deep Sky Imaging with the ETX 125

Last night was an excellent night for astronomy.  The moon rose late and skies were dark and the seeing good.  I mounted the ETX 125 in polar mode to see how it would perform on deep sky imaging.  The answer is as I expected.  GOTOs and tracking are excellent, from a visual point of view.  However, the gears are just not built for long-exposure imaging and even 30 second exposures showed stars as streaks. I'll just have to wait until the 14 inch comes back before I can do more imaging work.
