This is the first part of the bicolor version. The O3 data is coming soon. Due to the high ambient temperature the ASI1600 can´'t reach the desired -30°C even with 100% coolingpower. Two degree difference from the darkframes is obviously not a big problem and i lived with it;). This Ha version is nearly unprocessed; only some background denoising and some curve adjustments are made.
