Here’s a my image of an ISS transit last night. This was taken at 11:59:12PM in my backyard in Elk Grove, California. ISS Angular Size: 59.78″ Moon Phase: 96.9% Waxing Gibbous Transit Duration: .47s This was captured using a reduced EdgeHD 800 with an ASI1600mm running at unity gain at .6ms which captured the ISS along with the luminance data (2000 frames of R), then 100 frames in each R,G,and B filters to draw out the color. The ISS was captured in 6 frames out of 2000, which were separated, stacked, sharpened, and overlaid back onto one of the areas captured in the pass, which was overlaid with a LUM layer created by taking the rest of the 2000 frames of the moon in the red channel. The moon wouldn’t quite fit in the field of view, so the full size image is a 2 panel mosaic.

All circumstances were perfect for a good ISS lunar transit, I didn’t even had to travel at all and ISS were only 465km away from my location. I got my transit predictions from Calsky, charged the batteries on the night before and I was ready for the challenge. The sky was clearing nicely after sunset despite the cloudy forecast, so I hoped this might be my night. I used a Skywatcher 150/750 newtonian telescope on EQ3 mount and a Canon 1200D in prime focus.I took a few test shot on the 99% illuminated Moon, expo time at 1/1250 and ISO 400. I was considering video over single shot, eventually choose the latter. Then hesitating between shooting in raw format, but due data jamming I didn’t want to risk missing it so I went for jpeg format.I started taking photos in continuous mode 2-3 seconds before the predicted transit and when I found two of my shots had ISS on it I was very happy.

I used the Transit Finder website to plan the shot a couple of weeks ago. I set up my gear 2 hours before the transit to let the scope acclimate. The clouds cleared just an hour or so before allowing me to refine focus on the Moon and capture some Lunar data. I actually called my wife and daughter outside to watch the ISS rise and pass the Moon. They were impressed! I captured the transit as a section of the whole image which was pieced together as a mosaic afterwards.

Full solar disc image – The International Space Station transiting the Sun as seen from Wimbledon on 18th June 2017. This is a composite of the with the Sun consisting of a 6 panel mosaic and the ISS extracted from the individual AVI frames and then blended in darken mode with the full disc solar image. The camera dropped some frames towards the end of the transit, hence the lack of a full sequence.

58″ transit on November 10th, 2019. Transit duration across the whole moon was 0.57s. The surface of the Moon is stacked. Equipment: Celestron NexStar 8SE, Orion Atlas EQ-G, ZWO ASI224MC, ZWO ASI183MM-Pro, Baader 610nm Near-IR Filter.
A single frame in Hydrogen Alpha out of about 500 when I captured the ISS transiting the Sun on April 20, 2020 at 8:00:27 PM UTC time. I was on the very edge of the transit path so there were just 4 frames captured. Currently there are 3 crew on the station; 1 astronaut and 2 cosmonauts (Chris Cassidy, Anatoly Ivanishin, and Ivan Vagner). Equipment used: Coronado SolarMax III (single stack only) Celestron AVX mount Grasshopper GRAS-50SM iMac running Astro IIDC and Photoshop 6

Daylight Lunar Transit – 8-23-19 This was at 8:15am in the morning, sun came up at 7:06am, last quarter 50% moon. Transit-Finder.com info: ISS angular size: 59.08″ Az.: 204.4° ; Alt.: 62.8° Transit duration: 0.61 s Angular separation: 2.21′ Celestron C6 with Canon 5D IV, 4K video mode, video frames aligned and stacked in Photoshop, edits in Lightroom. This was my first time using the Celestron C6 for a transit, and also my first time attempting a daylight pass. Luckily, this wasn’t far away from where I work, and didn’t cause me to be too late on a Friday morning. Very happy with the results from this. I have had bad luck with the weather on most lunar transits lately, so it paid off to keep trying.

Two International Space Station transits within 5 hours! What was special about this event is that the two centrelines (lunar and solar transits) were crossing each other. So I did my setup at the crossing and waited for both transits from the same location. First the lunar transit happened at 4:06am which was followed by the solar transit 8:57am. Location: Hungary Time/date: 05.07.2018 4:06am and 8:57am Equipment: Skywatcher 150/750 newtonian telescope, Canon 600D Composite shots
