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.
