The good transparency of today's sky allowed this first attempt, using an IR filter.
Unfortunately, seeing degraded considerably during the day, and wind gusts were present. The planet's proximity of the Sun further influenced seeing. The image used a single 5min SER, from which only the best 50 frames were selected to stack (AS4). Exposure was 3.5ms and gain was zero. Sky background subtraction was performed in SharpCap.
