One 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. 🔭 ☀️

New 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! 🔭 ☀️

My 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! 🔭

I 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. 🔭 🌞

I very luckily captured a shooting star as I was taking a picture of Orion with my iPhone! 10 second exposure, iPhone 16Pro. Hokkaido, Japan. 🔭

My 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. 🔭

I 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!

I 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. 🔭

I 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!

This 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. 🔭

A 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! 🔭

I 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. 🔭

This is the kit my son and I used. We used a 1 meter long 15cm diameter cardboard tube from the hardware store - the type used as forms for concrete pillars. Everything else is just scrap bits of plywood screwed together. Let me know if you have any questions! Good luck!

Tonight’s moon and Saturn. Not the best picture of Saturn you’ve seen but not bad for an iPhone held up to a homemade cardboard tube and scrap plywood telescope! It was amazing to see it through the eyepiece. Wish I could get a better picture. 🔭
