Description

The moon age was 8 days, 15 hours and 30 minutes to be precise, phase 68%, elevation 45°, 10° of azimuth prior to meridian transit at around the middle of the early evening session. The current favorable libration in longitude brought Mare Humboldiatium into full view.

The transparency of the air was good this evening, but we had two layers of clouds one coming from the east the other from the west (east meets west) both apparently with different temperatures causing air turbulences.

First light through the new Sightron IR640nm pass filter which arrived today. The exposure times were about half of that required when using an IR742nm pass filter because the ASI290MM's response is much higher at shorter near-infrared wavelengths. This is quite a benefit when the air is dancing the night through. Teaming up, short exposures (faster fps) and infrared both help reduce the impact of unfavorable seeing.

The final image is a stack of 600 frames, 2ms, gain 100, 172fps, a three-panel mosaic, FL=750mm.

The exposure time of all image stacks of 600 frames each in the revision is below 8ms at gain 200 and 140-170fps, FL=1500mm.
