For a change the bad weather is leaving us alone and we are having some great conditions for imaging.  The images of this week are probably the best of this year for me.  I hope the streak of seeing continues. Saturday evening I tried my old Celestron Barlow Shorty Plus, which gives me an F/20.  the light reaching the chip is a lot less and need to reduce the exposure time to 1/15sec. and the frame rate running the 640×480 image went down to 10 fps.
