M51 and M3 are old favorites. M94 and M109 were new targets for the
night (3/11/16). Scope used was Celestron 8 mounted on AVX mount. Optical train
included Celestron 0.66x field flattening focal reducer stacked with
Antares 0.5x focal reducer. Two star alignment with 4 calibration stars and Celestron "All Star Polar Alignment" was use to align with true celestial north. Images were acquired with 25 15-30s
exposure frames in FITS format. Post processing was with Fitsliberator
using the ArcSinh(x) transform to TIFF format. Red, green and blue
layers were colorized and recombined using Paintshop Pro 9.
