Music: Rendezvous With Rama by Stellardrone Last night I tracked ISS during an 83 degree high pass using my open source SatTraker software: https://github.com/AstronomyLiveYt/SatTraker A Starlink satellite (Starlink 1044) was caught on the finder camera flying by ISS, watch for that near the end of the video (the Starlink satellite was about 300 km higher than ISS). The main telescope video has been stabilized and stacked in a 5 frame rolling average using custom software which also encodes the time, altitude, azimuth and range of ISS on the video file based on my location, the video's metadata, and the orbital elements of ISS. ... https://www.youtube.com/watch?v=pHAXK8OJFnM

Manual processing of the raw STEREO heliospheric imager data. NASA's method of automatically processing the heliospheric imager data relies on using previous images to calibrate the current images. The tenuous heliosphere is not visible in the uncalibrated data due to glare from the sun. Processing the images based on the images that preceded it inevitably leads to processing artifacts from bright planets and stars. In order to process the raw data, I used PixInsight's dynamic background subtraction to remove the glare from the sun from each image using only the data present in that same image. This seems to produce a much clearer star field at the expense of some residual solar glare. 2 hour cadence for the month of September. Future videos will further refine the dynamic background subtraction technique by increasing the sampling of each image. ... https://www.youtube.com/watch?v=tVDoN4bpODk
