First image with recoated 10 inch mirror

Hi all.
Weather was horrible with wind and cloud but I was determined to star test at lleats, my newly recoated mirror (see thread in general chat). Well, some stars appeared, so I set it up and decided to forgo star testing and wach the modded 350D on after collimating the newly installed mirror. I got off a shot of the jewlbox a single shot of just 20 seconds at ISO 1600, no dark, flat or noise subtraction. Taking other test shots it looks like the sky background will be reached in 60 seconds @ISO 1600, and thats with the uv/ir filter, on a moonless night at my location. It looks like my rig will be able to pull in more photons per minute now with better contrast, shining a light down the tube reveals a perfectly reflecting mirror now, no blemishes

Note, I took the pic of the Jewlbox in breaks of cloud, it was being covered up again as I finished the exposure. Then I packed it in for the night.
