Polar Aligment (mander.xyz)
submitted 1 week ago* (last edited 1 week ago) by xurxia@mander.xyz to c/astrophotography@lemmy.world

I'm thinking about an IoT Polar Aligner. The main idea is to use a Raspberry Pi W with the camera module to find and detect the North Star and display it on the mobile phone. The final goal is to connect it with servos so that it can automatically align itself. Does anyone know of a similar open source project?

You're right. In fact, in the place there are many more eroded stones with shapes that recall strange and ancient beings (or parts of them). Although the pareidolia will have a lot of the blame 😅

As always with these news it is still too early to draw conclusions: more analysis and tests are necessary.

I agree. It is more a curiosity thing than a real life project. But it helps to show the potential of this SoCs and it is a good practice for a lot of things.

I found this tutorial about how to use a raspberry pi to add a digital panel to old cars (canbus port needed)

Lunar Halo (mander.xyz)

It is a bad quality photo taken from a mobile. The circle that surrounds the moon is formed by the refraction of the moonlight when passing through ice crystals present in the atmosphere. At times surrounding the moon itself you can see a circular rainbow (they all are, but we see only half of the solar rainbow). This phenomenon is called a lunar halo.

Tonight, if the clouds allow me, I wanted to take pictures with my Skywatcher Star Adventurer mini. As I'm going to set up a small telescope (a Celestron C90) I need a very good alignment to the Polar so that I don't have any traces left. Tips to make an alignment as accurate as possible? Thank you

I think it is an ideal traveling companion... small, light but good enough to enjoy the night sky

Thanks! I am saving for a 9-10" newtonian with a EQ6 mount

My first photo with a telescope. It is not a incredible shoot but I am very proud of it.

Yes, you can. Python has Email package to manage email through STMP protocol. I use it daily in my scripts. Attached link is a tutorial of Real Python:

Yes, the idea is use in the future Output.status as a way to route to different pages depending of the model result. For example, when /list endpoint is called I could return 1 to show the feed list, and 2 to render a page with a message and suggestions when the feed list is empty. The same with negative numbers but for errors.

I have developed a project in #python to follow #RSS feeds and send an email with daily news. It is more an excuse to practice python, git and design patterns than a real project, but feel free to use it if you find it useful. Suggestions, opinions and feedback are welcome.

Fluent Python is another good book to learn Python. It is very clear and it has a lot of examples.

[-] xurxia@mander.xyz 3 points 1 year ago

Thanks! I will try it. I was an user of this sw but recently I have moved to Pyto as it has more libraries (OpenCV, etc), pip support and a newer Python version. Pythonista has its pros too.

I find it very interesting and I want to do one with my kids. The guide is good from a step by step point of view about how to make one, but I think a couple of examples about what kind of data can someone get with it and what can someone expect to "view" could be very helpfull too

After preview it will be a paid subscription additional to Office365, the same strategy as Office Copilot. I hate this policy of pay for a product then still paid for more functionalities... at the end of the year you will have paid a lot.

Microsoft says Python in Excel will be included in a Microsoft 365 subscription during the preview, but “some functionality will be restricted without a paid license” after the preview ends.

I fully agree with the post. Except for a fast prototyping or a short personal script where it could be not necessary, type hint is a must. The subject is not only to guarantee that the program now runs without errors, but it will be still working right in the future too, even after a developer (either the original or other) make changes to the code.
