Due to the bad images obtained of M51 on the last session, I targeted it again tonight, but the light over in that area of the sky is just too much. Forget Ursa Major until I am out in a dark area, such as the Nielson observatory. Anyway, here is another shot of…

The ring is 50 images at .77 sec. Vega at 4sec. with Photo Shop saturation maxed. Notice the absense of spider vane effect in the image of Vega, due to the design of the Schmidt-Newtonian – a corrector plate holds the secondary mirror instead, giving a sharp image. Whispy clouds started to roll in when these exposures were taken.
