Description

On the eve of new year, the clouds unexpectedly cleared for about three hours.  Transparency and seeing were fair, the air dry, but I knew it won't last for long, so, I surrendered autoguiding the Samyang 135 which had a 50mm lens piggybacked for parallel capture of constellations. Fair enough, the result were two sets of two images each:

1. M35/NGC2174 and the constellation of Orion (Dec 31 LT).
2. M44 and the constellation of Canis Major (Jan 1st LT).

As usual, the spectacle was ended by new clouds rolling in, however, since the forecast was everything else but hopeful, this little simple session was quite a bit of luck. This time with bias and flats since the wide open 135mm lens tends to vignetting. Humidity was no issue.

Dithering by foot eliminated need for darks. A tripod has three legs. If you kick'm one by one, then, after the third kick, the image assumes its before-first-kick position and all is good. The remaining dithering is merely 'kick at will'. My next e-booklet will be about Deep Space Imaging. Title:  Get the kick out of it!
