Dew Test and Dark Nebulae

Happy Autumn! Drifter observing report,  9/21/2019, Eagle’s Ridge (912m), SQM 21.2: Saturday was the first dewy night for the beta Drifter. Since I don’t have active dew heaters installed yet, this was a good chance to try out an idea that’s been kicking around in my head: Shove some chemical hand warmers into the cavity in…

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…

The Moon, Updated Focuser and Tertiary

I had an observing session last week where we got clouded out pretty quickly–however it was still a transcendent experience due to the fact that we were approaching first quarter of the Moon. I trained the Drifter on the Moon as it approached the horizon. An opaque cloud cut straight through the middle, its edges…

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,…

Primary Mirror Linear Bearings

There has been progress with the second round of focuser prints, but I’m going to take a moment to sidetrack to the primary mirror linear bearings. This is for adjustment of primary mirrors to make sure the images merge into one stereo picture rather than two side-by-side. Up to this point, I’ve been planning to…

Custom 1.25″ Parfocal Ring Prototype

It’s hard to wait for 3d prints in the mail, so in the meantime, I designed two different parfocal rings. 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:…

Filter Cartridge Progress

While waiting for focuser pieces in the mail, I’m working on the filter cartridges: A few new features. First, chamfers around the edges. 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…
