New moon EAA

I did not go out yesterday despite clear skies because astro weather sites said seeing would be poor.

Seeing was predicted to be a bit better, so I decided to setup early for some EAA. I was also hoping to see meteors from the Tau-Herculids meteor shower.

Inspired by D's experiments, I decided to use only flat and bias calibration frames. Darks only matters for long exposure. And since bias and flat are not exposure dependent, I can pick any exposure time I want. So I did a lot of 2.5s exposure and tried 4s (with mixed results).

Observations:

M13 Great Hercules Cluster (sky were still pretty bright)
M92 Globular Cluster - Hercules
M3 Globular Cluster - Canes Venatici
M53 Globular Cluster - Coma Berenices
M64 Black Eye Galaxy - Coma Berenices
M5 Rose Cluster - Serpens
NGC 5846, NGC 5850 Galaxies - Virgo
NGC 5774, NGC 5775 Galaxies - Virgo
Polaris - could not separate Polaris A from B
C1 Polarissima Cluster - Cepheus
NGC 5906 Splinter Galaxy - Draco
M102 Spindle Galaxy - Draco
M101 Pinwheel Galaxy - Ursa Major
M57 Ring Nebula Lyra - without FR
M13 Great Hercules Cluster - again, this time without FR
M101 Pinwheel Galaxy - again, this time without FR
Tau Herculids - meteor shower - caught a nice one while stacking but hit revert frame, waited some more and caught another one (see below), also saw one with the naked eye - not easy to catch meteors given the small field given by the camera
C27 Crescent Nebula - Cygnus
M56 Globular Cluster - Lyra
