M42 - Orion Nebula with Star Adventurer
Trying out the Skywatcher Star Adventurer Pro tracker.
Polar alignment with QHY PoleMaster.
I've fitted a ZWO miniscope and ASI120 mm s guide camera to the L bracket so will be able to guide in RA in the future. Didn't set that up for this image.
Fairly easy to adjust tracking alignment - some vibration and lost subs if I moved too close or walked near mount - may need a heavier tripod than my Manfrotto 055 - at least for backyard.
Taken with a modified Canon 80D with an IDAS D1 light pollution filter and a Samyang 135mm lens wide open at f/2.
40 x 50 second subs at ISO100.
Light pollution measured at 19.44 mag/arcsec2 - fairly poor for my site - maybe snow on the ground has affected that.
Session terminated by some cloud moving in - I like the idea of letting this tracker run for hours - my AstroTrac tt320x ag could only run for about 100 minutes before reaching end of timing screw.
