Oregon Star Party 2019 and Beta Drifter

It’s been a while, so there are two big things to cover. #1, showing off the beta Drifter at Oregon Star Party. #2, yes the beta Drifter is born–what’s been changed and how does it work? Oregon Star Party 2019 came and left quicker than Oumuamua but what an incredible weekend! Analog Sky set up…

Drifter Alpha Short Takes

Here in Western Oregon we are in the cloudy part of the year when observing sessions are few and far between. This gives rise to arguably the world’s most innovative telescope making scene, but also makes it hard to test prototypes. Still, I’ve had a few great sessions that taught me a lot. #1 Dew-Session…

Analog Sky Drifter Prototype 1 Notes

So it’s been a while since I updated this blog. That’s because the Drifter prototype 1 was finished 8-12 months ahead of schedule, in time for Oregon Star Party (OSP) 2018. I was too busy building it to post any updates. Many thanks to Jerry Oltion for helping me out of three or four jambs,…

The first is a fixed-height ring that uses grub screws the same as the existing products on the market. 3d printing these is still cheaper than purchasing retail. The second is a little more radical:…

Second, finger holes at the top to help with screwing/unscrewing filters. Third, pattern on the triangular corner to help with grip and distinguish cartridges (and therefore filters) in the dark. Cartridges will…

The Russ Rule

I’ve already mentioned the Russ Rule in one post, so I thought I’d better explain that. Russ was my neighbor for several years. At the time of writing, he’s 100 years old. Russ has lived alone for decades, but lives a full life with minimal help of family and friends. Up until last year, he…

Filter Cartridges

Have been working lately on the filter cartridge design, since it affects the position and design of the focusers. Filters are a pain to use on a dark night. They are delicate, fragile, and easy to smudge, scrape, or drop. So you keep them in cases that snap or screw tightly, which are difficult to…
