Mercury and M45
The Moon has moved too far east to be in the same frame as these two now. So I slapped the 300mm lens on and took a bunch of pix. There is a fine line between digital sensor sensitivity and noise: low ISOs give the cleanest image but the faintest stars for a given exposure. Whereas high ISO give the noisiest images but with the brightest stars. After playing with them all in post-processing, I decided that ISO 400 with some wavelet denoising was the best compromise. Taken April 27, 2009.
