So the stars remained better fixed over the 5.5 hours of shooting. In the second clip from January 20, taken with a quarter Moon lighting the sky, the mount was autoguided, using an MGEN3 auto-guider. Clouds pass through the field during the shoot. The field also drifts north due to slight misalignment on the pole. So the stars wobble back and forth slightly due to periodic error in the mount. In the first sequence from January 18 the equatorial mount, an Astro-Physics Mach1, is left to track on its own and is unguided. The camera was a Canon 6D MkII at ISO 3200 on January 18 and ISO 1600 on January 20 in the brighter moonlight that night. The William Optics RedCat 51mm f/5 astrographic refactor.Įach exposure is 30 seconds long, taken at a one second interval. Both are made from hundreds of frames taken through a William Optics RedCat astrograph at f/5 with a 250mm focal length. The video at top contains time-lapses shot on two nights: January 18 and 20, 2021. TECH DETAILS FOR “TRACKS OF THE GEOSATS” VIDEO: For a video of that phenomenon see my video shot in October 2020, below. During flare season around the two equinoxes geosats can become bright enough to be seen with the unaided eye. The satellites are visible because they are high enough to reflect sunlight even in the middle of the night, as the sequences each end about 11:30 to midnight local time.īut in this video the satellites are not flaring - this is their normal brightness. You’ll also see some flashing or pulsing satellites - they are likely tumbling objects, perhaps spent rocket boosters. You’ll notice some satellites travelling diagonally - they are not geosats. From a site in the southern hemisphere the geosat belt would appear north of the celestial equator. So parallax makes the geosat belt appears south of the celestial equator in my sky. That’s because I live north of the equator of the Earth, at a latitude of 51° north. In this video, however, they appear about 5° to 7° south of the celestial equator (which runs through the famous Belt of Orion off frame at top). The green box is the field of view of the telescope (shown below) that I used to take the time-lapses. This chart from SkySafari shows the belt of geosats through southern Orion with the satellites identified. The region of sky in Orion below the Orion Nebula (the object at top) lies south of the line that bisects the sky into northern and southern halves called the “celestial equator.” Most geostationary satellites also orbit in Earth’s equatorial plane and so appear along a belt near the celestial equator in the sky. But in reality, it is the stars that are in motion behind the satellites. What would normally be satellites fixed in one spot in the sky (after all, they are called “geostationary” for a reason) instead trail into short streaks traveling from west to east (right to left) in the frame. Install LRTimelapse via the provided installer, this will install LRTimelapse and all needed Lightroom Addons automatically.The camera is on a mount that is tracking the sky as it turns from east to west, so the stars are staying still. System Requirements and Technical Details High performance video rendering engine for high quality videos in up to 8K resolution and in MP4/H.264, ProRes (even on Windows), H.265 and MJpeg. Seamless integration with Lightroom CC Classic, 6, 5, and 4 with the powerful LRTExport plugin. This gives you the best quality possible. Make the “Holy Grail” of time lapse photography – (day to night transition) really easy – either by just manually adjusting your camera when shooting or by using a ramper like qDslrDashboard or others.ĭeflicker with one click – do this based on the look of the developed images without having to leave the RAW-workflow. You can use the full potential of Lightroom / ACR for color grading and even animate Graduated-, Radial- and Paint-Brush-Filters Features of LRTimelapse ProĪnimate and Keyframe Exposure, White Balance, and any other Lightroom editing tool over the time. It allows keyframing and grading of time lapse sequences in an all-raw-file-based workflow, utilizing the Adobe Camera RAW develop engine implemented in Lightroom (CC Classic (7), 6, 5 and 4) and Adobe Camera Raw. LRTimelapse is being used by most known time lapse producers and many amateurs. Free download LRTimelapse Pro 6.0.1 full version standalone offline installer for Windows PC, LRTimelapse Pro Overview
