Issue installing Starnet++ on Linux Mint Una on Dell N5040

Are there no linux experts in this forum -
They are all at default settings

How’s my imaging coming along
AstroMuni replied to Jjmorris90's topic in Getting Started With Imaging
Thats great progress indeed.... I find that the hard part is learning how to use the various software tools to bring out the best from your images and that takes time. I would suggest you try processing your older image and see if you can achieve better results with what you have learnt so far. -
If you see even the hubble images its not very colourful. Its filled with these dark areas and your image captures those well. 👍 You may wish to crop the image so you can bring out the salient features better.

In a nutshell the lens or mirror is bringing the light gathered through the various portions of the lens/mirror into a small circle. This is what you see depicted in the various science papers. So think of it as a collector of light, hence the larger the lens the more the light gathering power. Here is the basic science as explained in BBC bitesize https://www.bbc.co.uk/bitesize/guides/zt7srwx/revision/1 If this is too basic then let me know To make it more complex, various wavelengths of light bend at different angles so they will not end up in the same point in the small circle. And this is where comes the need to use multiple lenses to correct for the various errors you hear about (coma, chromatic aberration etc.)

In a nutshell......If you are using a driver such as EQMOD you dont need the Synscan in between, as it has all the functionality built into it. So folk (like me) who have switched to using the laptop to control the mount via RPi dont use the Synscan at all

Check out this video, which might answer some of your questions ......

Need help. The kstars crashed on my MacOS and I had to reinstall. Now for some strange reason the star sizes when using alignment tool (in simulator mode) are so tiny that its hard to spot them. Is there a setting for this?

How to schedule automatic photos through the night
AstroMuni replied to cmitran's topic in Getting Started With Imaging
As others have already said Astroberry (free) is the easiest way to start off on RPi. There is also StellarMate OS which sells for around $50 which also does the same. Stellamate is run by the developers of INDI, Kstars, but the software is also available for free. I use Astroberry on the RPi. Ekos has a scheduler that allows you to automate the tasks of startup, align, track, focus (if you have autofocuser), guide, capture and shutdown once the object of interest is out of view. It can then restart the following day to continue where it left off. There is plenty of documentation available online. And ofcourse there are plenty of users here who can help too. -
I am struggling to install TensorFlow that is pre-requisite for getting Starnet++ to run on my old Dell N5040 with 3GB RAM and running Linux Mint Una. The laptop does not have NVIDIA hence tried to install the GPU version with no success. My CPU does not support AVX instructions hence proving to be a challenge. I am not a Linux expert so will need detailed step by step instructions. Any help is appreciated.

Ekos plate solving. No go?
AstroMuni replied to Steenamaroo's topic in Imaging - Tips, Tricks and Techniques
On the days platesolving hasnt worked for me its generally due to very high level clouds that reduce the number of stars its able to recognise. They are hard to spot but when comparing images from a previous night, its obvious. In my case I use the ASI224mc as my main camera on a 130/650 scope. The guidecam is ASI120mm on the Astro essentials 32mm guidescope. I prefer using the internal Ekos Stellarsolver to external ones. I run Ekos from my Linux based laptop and the RPi just runs the INDI server & drivers. As your problems seem to have started after a software install, I am guessing some config has changed in that process. What would help us is if you post the solver settings esp the Options profiles that you have chosen eg: 4-ParallelSmallScale. And I am guessing you have downloaded all the recommended Index files for your FOV onto your RPi. -

AstroMuni replied to Steenamaroo's topic in Imaging - Tips, Tricks and Techniques
Next time try doing platesolving with main scope as well to see if it has the same problem. -
Ekos plate solving. No go?
AstroMuni replied to Steenamaroo's topic in Imaging - Tips, Tricks and Techniques
Are you platesolving with guidescope? What is your main scope? Per se there is nothing wrong in doing it this way IF both guide and main have been aligned to same point. Using guidescope for PA should work even if its not aligned with main, but when it comes to actual imaging, it could lead to the main object not being correctly positioned in FOV. -
Astrophotography Laptop Specs...
AstroMuni replied to Ian McCallum's topic in Getting Started With Imaging
I use ZWO cameras as well and primarily capture DSOs. My laptop is an old i3 with 3GB RAM and 256GB HDD running Linux Mint. I also use an RPi as it gives me the luxury of being able to sit inside my house on laptop without having to run wires to scope etc. The RPi runs the INDI server and drivers and comes with 2 USB3 ports + 2 USB2 ports. I changed to Linux when my laptop was struggling to run windows 7, 8 and I couldnt be bothered to buy a new laptop. Ref long exposure times most of the hardwork is being done by the camera and it only calls upon computer resources when it saves the files. I tend to use a combination of 30s and 120s exposures as my camera is just a good old uncooled ASI224mc and I figured out that light pollution in my area anyway contributes a lot, so I can get away with short 30s exposures. See the video by Robin Glover on optimum exposure. -
Can you recommend a good UV/IR cut filter for planetary?
AstroMuni replied to StuartT's topic in Getting Started With Imaging
Have you considered the filter from ZWO? I use that with my ASI224mc -
Awesome picture. So many galaxies in one shot

You are correct, but its a bit deeper than that. So its referring to the location of INDI server which then looks for local or remote device drivers. So you could potentially have the INDI server running on the RPi but the devices connected to another machine, in which case you would specify the location of the drivers in the Remote text box in Profile editor. @Ian McCallum if you hover over the the Local or Remote buttons you should see a popup with help.

Beautiful sights 👍

I give up - skywatcher 9x50 raci finder
AstroMuni replied to Starslayer's topic in Getting Started Equipment Help and Advice
Absolutely agree. I remember trying to figure out how to read the SW polarscope as my manual shows the constellation view whereas the scope has a clockface -
Here is my poorer cousin image of same object taken over 2 nights in Jan. Taken using the ASI224mc attached to the Celestron 130 scope on a EQ5 pro mount.

Great image. How many exposures is this? EDIT: Ignore Saw the info on the image

ASI294MM Dark frames quality measurement
AstroMuni replied to barbulo's topic in Getting Started With Imaging
I have searched on the internet for examples of amp glow from ASI294 and all show just one spot from which amp glow is emanating. So worth checking that the rest are from camera or stray light. -
ASI294MM Dark frames quality measurement
AstroMuni replied to barbulo's topic in Getting Started With Imaging
Thats quite a few amp glow areas on the Master. Generally I have seen only one and its fuzzy not having starry lines. Perhaps someone with more experience of your camera can comment
