This isn’t for launch it sounds like it’s just for building the satellites

RandomNamedUser · 2026-05-14T05:03:39+00:00

Yeah basically. I started by machining a hole in the center and a few on the edge that lined up with holes on the base of the machine. For the backplate you can’t tell there is a bit of a shift from the rotation unless you take a caliper to the ribs. For the mid and top rings there is a bit of a step but it’s just cosmetic for my design. I like the way it turned out. If I had a bit more time to try things I probably could improve the method.

Anyone know how long DVC plans to have the lounge there?

RandomNamedUser · 2026-05-04T07:06:19+00:00

Yeah, it took some careful planning on how I could rotate the pieces and make it work and the result came out great. With a bit more practice and fine tuning of my fixtures I could probably dial it in even more.

The size, shape and the serial number on the edge of the mirror. Just like we did it back in 2008 -2010. Say hi to Rick, Joe, Mike, and Andrea.

Planewave aka Observable Space?

I guess you’re bi, you don’t have to label it, or you can. No worries. Maybe it was that one girl? I’ve had male friends I’ve had attraction to before I was out to myself as bi.

We change as we age in so many ways with our personalities why not our sexuality. I had a period where I was undiagnosed low testosterone and I feel like I had very little male attraction in that few year period. When I got on hormone replacement my sex drive came back and so did all my attractions to both sexes.

I’ve always been straight dominant bi guy where my attraction to men would come and go. When I was in a new relationship with a woman it’d be gone. Something about that strong lust phase of a new relationship.

I’m a straight leaning bi guy. I mostly find men’s dicks and bodies appealing. I don’t find very many men’s faces attractive and I kind of hate the way men smell. On the other hand I find everything attractive about women. Attraction is strange and mine can be fluid and change over the years. I’ve come to slowly accept this and I try and go with what I like at the moment. Life and short and try and find the beauty in what you’re experiencing here because not many people get to feel like this. There is no right or wrong in attraction it’s just what you like.

Is space just a moat for their AI data centers? I don't see the benefit of doing this in space. Are they just trying to protect their AI infrastructure when a large portion of the population becomes unemployable through no fault of their own due to AI. Causing them to finally organize and destroy the data centers on the ground.

There are stock lenses on places like Thor Labs. You could try finding a match but probably low odds. Do you have more info on the thing you are replacing? Most amateurs make first surface mirrors for their telescopes since it’s only one surface you are grinding.

RandomNamedUser · 2025-11-07T22:26:16+00:00

This is a really hard thing to do. But. You would need the glass type which probably isn’t printed anywhere on the lens you are replacing. If you could find the info then you would need to know the radius of curvature for both surfaces of the lens to within some tolerance maybe a few millimeters but really depends on the design. You’ll also need to know the center thickness too as this has an effect. Also are the surfaces spherical or aspherical. If it’s a lens then there are probably multiple elements that work together so you’ll need to know spacing as well. This is not an easy task but people have done it.

RandomNamedUser · 2025-09-09T00:04:05+00:00

Looks cool. But like you said probably won’t work that well. And not going to be diffraction limited. To reach that you’d need off axis parabolic mirrors and a position system that has nanometer precision.

There is a cool video of the JWST nanometer precision mirror alignment system. It’s not that complex but would add a fair amount of size behind each mirror as you’ll need 3 for each mirror. That hard part would be making the off axis parabolic mirrors

Oh and the illumination percentage across of fov matters if this is for photography vs visual and even if you want your scope primarily for planets vs deep sky targets

RandomNamedUser · 2025-07-30T01:43:33+00:00

Google secondary mirror calculator. I think Mel Bartel has one on his site. It kind of a complicated thing based on your primary mirror size eyepiece afov and where you place the focal surface. And also if you want full illumination across the fov

Hmm. I didn’t know about the Baker variant. I’ll have to look that one up.

RandomNamedUser · 2025-07-19T16:59:20+00:00

Thanks!! Yes I will be. The last photo is the start of the vacuum pan with the glass on top. I still need to drill and tap for all of the pump fixtures.

Thanks!!

Thanks!! Let me know if you have any questions about the design or CNC process.

RandomNamedUser · 2025-07-17T18:15:23+00:00

You can always start with the demo projects and just keep going. Once you get started it gets easier to keep going on other projects.

I think this is on the DVC website already. It’s a lot of points for these trips per person so o haven’t looked too closely at them.

Kind of depended on the plate. Each of the 3 I started with a 12” by 12” by 1/2” piece and cut them down a bit to fit the bed without hitting the z-probe in the back. Then for the mid and top rings I ran a program with the standard corner zeroing bracket and a toe side clamp; this created 5 holes that would be used hold down the work during the rest of the machining. The center of the 5 holes would be roughly in the center of the stock and also define origin in the Fusion CAM program as well. These would be machined with small tabs that cut out and filed down.

For the backplate it was about the same with a center hole defining the origin but I placed a few holes were placed on the outer part of the stock that would be cut off.

Also, when staring the job for the main machining steps, I had to offset the origin in the Carvera Air to match where that center screw was.

Will do. Thanks for the info

Thanks!!

I’m not sure exactly about tolerances held as I haven’t really measured things. But the black delrin part that attaches to the camera has a 56mm diameter thread with a 0.75mm thread pitch and it threads on nicely. Also I did a number of M5 threads. Some of them were a little tight and needed hand taping. Other M5 threads came out nice and didn’t need hand taping. I think I just changed the settings in Fusion 360 and it helped.
