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.

I bought a solar scope a few weeks ago (Coronado Solarmax III Double Stack) and one of my objectives was to capture a solar transit in Ha. My first attempt was not so successful as my frames were blurry and not really in focus. After reaching out to a few people on Instagram I went out and captured what I was able to. I definitely need a mono cam if I want to be more successful.

The chances of capturing this transit were looking bleak with the high clouds that were overhead. The sun was fading in/out and it was difficult to get a good focus let alone figuring out the right exposure. With less than 5 mins to the transit, I still hadn’t really figured out a good exposure because the clouds were ever changing the brightness levels. You’ll see in the video that clouds were rolling by and I was freaking out that I wouldn’t get anything so I jacked up the exposure to be able to capture at least something going by. But then the clouds started to thin and I was seconds from the transit happening. I furiously was moving the exposure slider in real-time watching the histogram and desperately trying to keep it at ~2/3rds exposed. The transit lasts only 0.73 seconds so you have no room for error. My heart was pounding and my hands were shaking. Luckily, at the exact moment, the clouds thinned, I dialed in the exposure, and the ISS flew by! As soon as it happened I cheered out loud to myself where I was set up in a local grocery store parking lot. I’m sure people thought I was crazy. By the way, as usual, the clouds thinned way out and as I was all packed up 15 mins following the transit, the skies were clear! ARRRGH! Why do we do this hobby?

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.

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).

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.

This is the composite showing the ISS path across the Sun. I took that on the afternoon of April 26th using my Explore Scientific 127mm refractor with a 2″ Lunt solar wedge and ZWO 174MM camera. When there are high, thin clouds, a white light telescope will do better than an H-alpha telescope. It also showed a nice but very small sunspot group. This particular transit was nice because it was only five minutes down the road from me.
Was the taken on the afternoon of April 17th – in the thickest part of the COVID lockdown here in Colorado. I had to drive an hour to see this transit. How locked down was it? One of the signs I passed just a few miles from the observing site read: “Chaffee County is closed to out-of-county visitors”. Thankfully the pull-off I’d selected from a satellite view was almost perfectly empty. I took my images and went home straightaway. This image is an H-alpha view of the Sun and transit taken with a Lunt 100 H-alpha telescope and ZWO 174MM camera. It was a quiet day on the Sun – no activity on the surface but there is a nice little prominence at about 10 o’clock.
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
