Drifter

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,…

Drifter Dream Views #1: Lagoon & Trifid

Back in the 80’s they used to sell telescopes by surrounding a studio shot of the scopes with various full-color astrophotos of the objects you could see with each one. The implication–at least to my 8-year-old brain–was that these astrophotos represented the view through the eyepiece. Two objects from those ads stood out to me…

Tertiary Housing Beta 1

Imagination. Reality. Here’s a completed tertiary housing. All the pieces connect well. The mirror mount works very well. The focuser works in the housing. The filter cartridges still need some tweaking. Using a screw for a friction fit doesn’t work since the cartridge just pops out from the pressure. However, using the screw in a…

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…

Focuser Modifications

I was able to brute force the screws through the too-small holes in the drive plate, so the focuser came together for testing. Looks like we’ll call this one v0.1 as 0.5 was a little optimistic: So far, it only works with a gravity assist, which I believe means the drive plate in standard Onyx…
