Always loved this one. Last three nights were clear, and we added 4 hrs of H-alpha to what we had from 2015. Then the Gremlins found out that we were trying to do astrophotography. The middle night we lost all data due to stupid finger trouble. Then last night the generator inlet valve failed for the second time, so we only added 2.5 hrs of OIII. Auuugggh.
But we now have 10 hrs of Ha and 9h30 of OIII. The weighting is 50/50 old and new.
For the one of us who is colourblind, the HOO mapping produces an apparently grey (monochrome) image. Consequently, for all those colourblind chaps out there in astro-land, we present the image as HHO. Purists can effortlessly produce their own HOO version with a couple keystrokes.
North is on the left. The thumb is cropped to the Good Bit. The
uncropped high-res image shows more faint extensions. The full field is approx 36 min arc across.
Combo of cameras: Aspen GC16M and FLI PL16803 (same chip). Scope: 20 inch PlaneWave CDK. All robotics aquisition and processing as always using our own country-comfort software.
We're sick and tired of generators failing, and are looking to get a pair off Made-In-Australia 200 AH lithium idiot-proof charger-manager-inverter combos plus solar panels.
