Converting an app that started per-client deploy, single-tenant, cloud-ignorant and mono-node to multi-tenant, multi-node, cloud storage and a cluster of a few nodes.

On one hand, I regret not having thought it could find a market and I now have to do this and plan a migration.

On the other, I saved a lot of time going to customers instead of building the boring side first... So I don't know what to think of it.

I find that most of the development work is now "ops" instead of user-facing features (either addition, removal, or polish) and am a bit perplex at this.


Here is a 6in f/5 travel truss dob kit by my friend :

Wallace, my 6” f/2.8 :

And my tiny but mighty 3” f/4 : https://www.printables.com/model/1475113-76300-pocket-dobson

Wallace is built, but Gromit, a 16.5” F/3, is under progress. Working on the mirror and CAD :)


Re : running relaxed, it is said that the real marathon is the training you put in, and the race itself should feel like a celebration. I am not anywhere near elite level but felt that for a lot of races. The hardships of the training enables a state of deep calm, joy and feeling like you are flying the morning of the actual race. Nights before races are often very bad, like a last storm before everything clears and your mind is finally empty when you get into the corral. Then, with a clear mind, you proceed to run with joy despite being physically tired by the training and sleepless night.


Hi, I could send you the link but as outlined in the post, this specific mirror was very out of tolerance..


I looked but AliExpress makes it impossible to locate even specific sellers, like BohrOptics, who I found to have consistently good quality (bought a beam splitter and fused silica ball lenses from them).


This article gives great impressions of what you can see with your eyes through various sizes of telescopes : https://www.deepskywatch.com/Articles/what-can-i-see-through...


This one is a bit of a joke with my telescope making friends, but ticks all the boxes of what I consider a real telescope. You can actually buy 76mm entry-level telescopes, but they often have an unstable mount and bad optics. Starting at 150mm, you already have a lot of punch under dark skies. Visual use, live digitally enhanced, or astrophotography are 3 different hobbies.


Small mirrors with a very low F-ratio are also something that you need to grind yourself. I have a 6" f/2.8 telescope and a 8" f/3.5 hyperbolic + ross telescope, and both aren't commercially available while being small mirrors !

Progress on my 16" f/3.2 is currently stalled though.. a multi-year project indeed.


Absolutely, second hand is the most direct path to getting a telescope.


Thanks, it's heartwarming. It's my current longest living attempt at a blog


This is the first time I've seen a build of the ABSDBS in the wild, thanks for sharing ! Sadly an 8" f/4 mirror has a very narrow range of acceptable optical quality :/. It's too bad you ended up with a bad one. Maybe refiguring it would be a great followup project though
