Okubo Heavy Industries @okuboheavy.bsky.social · 25/09/2026I’m heading to Tanegashima next month to hopefully watch the launch of JAXA’s Martian Moons eXplorer (MMX) mission. I built this little countdown timer to monitor the launch (and use this cool HCMS 2911 display I acquired). 🔭 #jaxa #mmx 151
Okubo Heavy Industries @okuboheavy.bsky.social · 15/09/2026Live Cloud Globe V2. Now with ISS and ISS pass predictions. I also made a custom PCB for it. I have a few extras if anyone wants to make their own. Based on a QtPy ESP32-S2. All the code is up on GitHub - github.com/OkuboHeavyIn... 🔭 052
Okubo Heavy Industries @okuboheavy.bsky.social · 13/09/2026Can anyone link me to a good tutorial for astro stacking using a Mac a small dobsonian and an iPhone. I’ve made a few false starts and I just can’t seem to figure it out. 🔭 011
Okubo Heavy Industries @okuboheavy.bsky.social · 03/09/2026I found an orange HDSP-2530 display for my Sky Sentinel overhead satellite tracker that I’m developing. Swaps right in for the HDSP-2531 (yellow) that was in before and looks lovely! 000
Okubo Heavy Industries @okuboheavy.bsky.social · 03/09/2026My 11 year old son is crazy about the JAXA MMX mission. I’ve been able to book the two of us a trip to Tanegashima for the launch. This will be our first rocket launch. Any tips for a newbie and any other fun stuff to do on the island whilst we are there for a week? #mmx #tanegashima #jaxa 🔭 🚀 160
Okubo Heavy Industries @okuboheavy.bsky.social · 07/07/2026Kayak build day 50: Finally got the deck closed up and started prepping the cockpit. #kayak 000
Okubo Heavy Industries @okuboheavy.bsky.social · 23/06/2026Day 40 of my Night Heron Sea Kayak build. Working on adding cedar strips to the deck at the moment. 000
Okubo Heavy Industries @okuboheavy.bsky.social · 21/06/2026Happy Summer solstice! 4 Solargraphs I set around Kutchan in Hokkaido, Japan at the Winter solstice and just retrieved this evening. Pretty happy with how these turned out. You can see Mount Yotei in a couple of them. 🔭 ☀️ 🌞 0143
Okubo Heavy Industries @okuboheavy.bsky.social · 25/05/2026Day 20 of the Night Heron kayak build. 020

Okubo Heavy Industries @okuboheavy.bsky.social · 28/04/2026I’ve started building a Night Heron Greenland kayak. I’m posting daily updates on my IG feed. If anyone is interested I can post updates here too. #kayak #boatbuilding 010
Okubo Heavy Industries @okuboheavy.bsky.social · 28/04/2026The gibbous moon over Mount Yotei this evening. 🌖 010
Okubo Heavy Industries @okuboheavy.bsky.social · 28/04/2026Frogspawn and salamander spawn in a big puddle near my house. Hokkaido, Japan. 010
Okubo Heavy Industries @okuboheavy.bsky.social · 19/04/2026ISS transiting the Sun here in Hokkaido a few hours ago. Pretty happy with this considering I used a telescope I made with mostly junk and cheap AliExpress parts and an iPhone held up to the eyepiece. 114mm Newtonian Dobsonian. Couldn’t have done it without transit-finder.com. 🔭 ☀️ 0164
Okubo Heavy Industries @okuboheavy.bsky.social · 16/04/2026Blink and you’ll miss it. Tiangong, the Chinese Space Station, passing in front of the Sun this afternoon. Once at full speed and then slowed down to 1/8th speed. (It’s very small, you might not be able to see it on a small screen. Moves horizontally right to left just below center of Sun. 🔭 ☀️ 260
Okubo Heavy Industries @okuboheavy.bsky.social · 16/04/2026Our local star. I bought a cheap solar filter from AliExpress. I don’t trust it with eyes but I do trust it with my iPhone. 114 mm Newtonian dob, 40mm eyepiece. NASA picture on the right for comparison. 🔭 ☀️ 2100
Okubo Heavy Industries @okuboheavy.bsky.social · 14/04/2026An iPhone picture snapped through the eyepiece of a homemade 114mm Newtonian telescope of Jupiter and the Galilean moons compared to the calculated image from thskylive.com. Isn’t science amazing! This picture was taken about 40 minutes ago in Hokkaido, Japan. 🔭 🧪 070
Okubo Heavy Industries @okuboheavy.bsky.social · 07/04/2026Disappointing to hear astronauts promoting Bronze Age superstitions about magic sky fairies whilst using advanced science and engineering to travel safely around the moon. #artemisII 🔭 262
Okubo Heavy Industries @okuboheavy.bsky.social · 03/04/2026This is really hard to see but I captured the Chinese Space Station passing in front of the moon this evening. I used my budget homemade telescope and an iPhone. The video is slowed down and is inverted so the space station moves from bottom left to top right. 🔭 010
Okubo Heavy Industries @okuboheavy.bsky.social · 01/04/2026I just finished building my cedar strip canoe and so today was launch day. Design is the Solo Day by Ashes Still Water Boats. Beautiful warm day at Lake Toya in Hokkaido, Japan even though there is still snow on the surrounding hills. #canoe #woodenboat 020
Okubo Heavy Industries @okuboheavy.bsky.social · 30/03/2026Single day Solargraph. This was an experiment in using a slightly larger pinhole. Trees are less in focus but the path of the Sun is very clear. 🔭 ☀️ #pinhole 0233
Okubo Heavy Industries @okuboheavy.bsky.social · 29/03/2026Two week Solargraph made from a Danish cookie tin pinhole camera and ILFORD photographic paper. Hokkaido, Japan. 🔭 ☀️ 0194
Okubo Heavy Industries @okuboheavy.bsky.social · 03/03/2026Worst lunar eclipse ever! Almost total cloud cover. This is the best shot I could get. 🔭 021
Okubo Heavy Industries @okuboheavy.bsky.social · 02/03/2026Despite 95% cloud cover, sub zero temperatures and strong winds, I just watched Regulus disappear behind the moon with my homemade telescope! 🔭 050
Okubo Heavy Industries @okuboheavy.bsky.social · 01/03/2026I took a picture of Jupiter and the four Galilean moons earlier this week with my homemade telescope. I can see two cloud bands on Jupiter and maybe the Great Red Spot if I squint? 🔭 0141
Okubo Heavy Industries @okuboheavy.bsky.social · 01/03/20261 week Solargraph in Hokkaido, Japan. I’ll try to set another up in this location for a year. This was made with an empty Fanta can, pinhole, ILFORD photographic paper and black tape. 🔭 ☀️ 🌞 0273
Okubo Heavy Industries @okuboheavy.bsky.social · 21/12/2025Pinhole Solargraph. 4 week exposure leading up to the winter solstice using an old aluminium Fanta can as a camera and ILFORD photographic paper. Hokkaido, Japan. #photography #art #pinhole #lofi 0183
Okubo Heavy Industries @okuboheavy.bsky.social · 21/12/2025Pinhole Solargraph of the 4 weeks up to the solstice. This is the best one yet I think. Looking forward to seeing the six month ones I’m setting up right now. 🔭 1133
Okubo Heavy Industries @okuboheavy.bsky.social · 18/12/2025Almost finished building a cedar strip canoe. Still need to finish making the seat and varnish everything. 020
Okubo Heavy Industries @okuboheavy.bsky.social · 07/12/2025One week Solargraph next to Hangetsu lake, at the base of Mt. Yotei, Hokkaido, Japan. Really happy with how this one turned out, especially the reflection in the partially frozen lake. It’s great we were able to leave it undisturbed in a place where so many people visit. 🔭 ☀️ 0204
Okubo Heavy Industries @okuboheavy.bsky.social · 01/12/2025The moon a few minutes ago from Hokkaido. 🔭 424223

Okubo Heavy Industries @okuboheavy.bsky.social · 30/11/2025The moon, Saturn and the International Space Station lined up between the trees just now. Hokkaido, Japan. 🔭 417014
Okubo Heavy Industries @okuboheavy.bsky.social · 30/11/2025The moon is looking beautiful this evening. 🔭 1193
Okubo Heavy Industries @okuboheavy.bsky.social · 25/11/2025New pinhole Solargraph! This one was in place for a week. Had a few really sunny days and then lots of cloud. Am I going to do a month long and year long one? You’d better believe it! 🔭 ☀️ 2408
Okubo Heavy Industries @okuboheavy.bsky.social · 24/11/2025My best picture of Jupiter yet with my homemade 114mm Dobsonian telescope. Also Europa below and Io and Ganymede above. So cool to see cloud bands on another planet! 🔭 190
Okubo Heavy Industries @okuboheavy.bsky.social · 16/11/2025I made a pinhole solargraph with an aluminium drink can, some black tape, a pin and a sheet of ILFORD photographic paper. This image shows the path of the Sun over the course of a day and the trees in front of my house. 🔭 🌞 110423
Okubo Heavy Industries @okuboheavy.bsky.social · 12/11/2025I very luckily captured a shooting star as I was taking a picture of Orion with my iPhone! 10 second exposure, iPhone 16Pro. Hokkaido, Japan. 🔭 0201
Okubo Heavy Industries @okuboheavy.bsky.social · 05/11/2025My first picture of Jupiter and the 4 Galilean moons with the homemade telescope and some moon pictures. All taken with the 17mm eyepiece and 2xbarlow. 🔭 090
Okubo Heavy Industries @okuboheavy.bsky.social · 05/11/2025The moon a few minutes ago taken from Hokkaido, Japan with my homemade budget 114mm Dobsonian and an iPhone. 🔭 0172
Okubo Heavy Industries @okuboheavy.bsky.social · 04/11/2025Tonight’s moon grabbed between clouds with my homemade budget telescope and an iPhone. 🔭 0151
Okubo Heavy Industries @okuboheavy.bsky.social · 30/09/2025I built a ¥3,000 (US$20) solar projector telescope with some cheap lenses from AliExpress and some scrap ply. My image of the Sun isn’t quite as clear as the one from the NASA SOHO spacecraft (3rd picture in case you weren’t sure) but it was much less expensive! This was a fun little project! 🔭 🌞 1110
Okubo Heavy Industries @okuboheavy.bsky.social · 22/09/2025I got to see and photograph the Pleiades last night with my homemade telescope. I was able to match up all the stars named in the free version of Stellarium and captured a bunch more too! I think the purple spot is a reflection from the eyepiece of the iPhone laser rangefinder. 🔭 030
Okubo Heavy Industries @okuboheavy.bsky.social · 19/09/2025I’m so happy to get this image of Saturn a few minutes ago with my homemade 114mm Dobsonian and an iPhone 16 pro held to the eyepiece! 🔭 0212
Okubo Heavy Industries @okuboheavy.bsky.social · 12/09/2025I got this Obi-Wan Kenobi 20 Years of LEGO minifigure along with another purchase on eBay. I didn’t want to take it out of the bag but I did want to build it so I put it together in the unopened bag. The lightsaber was the hardest bit to get in place! #lego 000
Okubo Heavy Industries @okuboheavy.bsky.social · 11/09/2025This evenings moon from Hokkaido, Japan. I’m still blown away with how much I can see with my budget home made telescope. I used the night cap app instead of the normal camera app and I think it gives better results. I also got my best ever view of Saturn but it was impossible to photograph. 🔭 0123
Okubo Heavy Industries @okuboheavy.bsky.social · 08/09/2025A while back someone posted an image of Popular Science magazine from January 1928. I was able to find a copy online (for a crazy price!) and it’s just arrived. It’s even more beautiful in real life and there are some fascinating articles! I don’t remember who posted about it but thank you! 🔭 170
Okubo Heavy Industries @okuboheavy.bsky.social · 08/09/2025I didn’t stay up to 3am to see the lunar eclipse last night but I did get to see some lovely views of the moon before I went to bed. 🔭 090
Okubo Heavy Industries @okuboheavy.bsky.social · 05/09/2025Help me Astronomy people. Has anyone ever used a live remote telescope to give a talk to school students? I’ve never used a remote telescope before but I thought it would be really great to show live views even though it’s daytime where we are. Not sure how feasible this is? 🔭 221
Okubo Heavy Industries @okuboheavy.bsky.social · 02/09/2025My new 3I/ATLAS t-shirt just arrived! 🔭 💫 070
