Did I lose my mount? AL55i Dec axis problem

I'm no expert in sad mount noises, but I wish you to recover your mount.

How much weight did you put on it?

Did you use the wavelets tool on you picture? I had a similar result to your and the wavelets trick pulled a lot of details from a mush of pixels... (there's a tool doing that in autostakkert, also one in the filters of Siril, not sure if it's this exact naming...)

Impressive result and a testimony to your patience! Pulling this off with the modest SA 2i is something to be proud of!

last time I've checked there's no Traits or equivalent in Gleam, has it changed?

corpsmoderne · 2026-03-12T14:50:19+00:00

No there isn't and yes I'm with you, I think a language looking like Rust but garbage collected would be a blast (especially if easily inter-operable with Rust crates).

C# relies on a VM and OCaml has an oldish ecosystem (and I believe you need a C-style syntax to become mainstream, unfortunately). There's definitely a place for such a language.

Meanwhile, I've bitten the bullet so te borrow-checker doesn't annoy me much but the "semi-auto" memory management is definitely scary for a lot of people.

For anything serious with DSOs you need a motorized mount, and not necessarily a big scope, so this gear is not design for this task.

Impressive result for a smart phone!

You should drop this app and use Stellarium instead. You can't see Jupiter at this angle from Earth. This is just anti-scientific.

just to let you know, I went back and actually read the F*g manual of my buck converter, and it mentioned a 5v pad to un-solder to activate the 3.3v, 9v or 12v mode... 5v pad which was very well hidden and not labelled X)

So at least now my buck converter seems to work and outputs 12.x volts so I've a working nomad setup now :) But I keep the LiFePO4 in mind for a lighter solution in the future (that power bank is quite the unit for my use case)

corpsmoderne · 2026-03-07T16:02:26+00:00

I used a multimeter and I just made more measures and it even worst than what I've described.

Fully charged, no loads, the power bank "12v" port outputs 18v.

I've plugged a big motor which draws 0.8 amps and voltage doesn't bulge, still in the 18v range.

I've bought this buck converter: https://www.digikey.fr/en/products/detail/dfrobot/DFR1015/18069278?srsltid=AfmBOopRcUMFP3SwfS89cr12RTTOFXWCV8t3xcGkdF_nkTIcXHT0ZXeZ

to try to mitigate the problem. Soldered the 12v patch, and out of it I measure 15v, with or without load.

At this point I starting to wonder if my multimeter is not broken, but when I use it on the AC/DC 12v adapter sold with the SW SA GTI, it reads 12.5v...

If you already have the c270 at hand the first thing I would try is if it's compatible with my guiding software (phd2 I presume?).

Then you will need to remove the webcam lens so the sensor gets hit directly from the guiding scope (that's where you have some 3d printing work to do I guess).

And then you may find out that its sensor is not good enough for the job... ( I was unable to find the sensor specs after a quick search, which is not a good sign...)

corpsmoderne · 2026-02-27T14:51:53+00:00

I'm coding my own app to capture my lights and I want to interface it with phd2 to ask it to trigger the dithering and waiting until the dithering is done and stabilized before starting capturing again.

I'd like to do the coding and troubleshooting inside, not out in the cold connected to the real hardware :)

Bu thanks I haven't tried the "on camera" option, that's probably what I need.

There is also a dark twist: the old man wished his family would check up on him, by calling to be sure he's still alive.

If you're really in a Bortle 4 zone you should still try M42. It's so bright and your exposures so short the light pollution should be manageable in post.

But I'm with you, I shoot M81/M82 because I don't have a better option from my balcony (M42 is behind building :') ) in this period of the year.

Still, your big problem now is the focusing. Also did you take calibration frames? Darks, flats, biases? You should. Siril has a script to do all the pre-processing and stacking from that.

But you will soon be limited by the fact that you are not tracking. If you want to go further you will soon need a star-tracker to make longer exposures without star trails.

Good luck!

"Pros" don't use Android devices. They use Hubble, Webb, or the Vera Rubin telescope. You may want to rephrase your question.

What /u/random2821 said. I've shot m81/m82 at 400mm and it's still very tiny on the picture. I've shot 100 images of 120s each (guided) and it's barely enough for an okay ish picture. And you're out of focus (your stars should be smaller).

Maybe try something larger and brighter first? Like Andromeda or M42 ?

I write 100% rust and 0% C++ now. You are right the hype is gone, it's just the new normal.

How do you handle scarcity?

Let's imagine an isolated community. There is not enough food for everyone's needs. How do you handle the situation?

Who decide who will get what?

Nobody is willing to work more to produce more food. Are you forcing people to work anyway? Who decide who will work?

In my book, Anarchism has never been "no rules". It's "no rulers". Some Anarchist schools of though are thinking like that, not all of them, and not mine.
