I will try to submit logs soon. Thank you.


Micheal Fields created a new topic ' Could not connect to focuslynx & my focuser not listed' in the forum. 3 months ago

Last night I was setting aside a bit of time to learn how to use Ekos and Indi. I made some progress but one piece of equipment didn't connect. That was my Focuslynx controller.

On A PC with Windows it occupies COM3 and connects without issue using the focuslynx controller software. However I could not get Indi to connect when I switched it over to my raspberry pi 3.
I did a scan ports and it found a port but I don't understand if there was something else I was supposed to do? Everything was "green" except the connection bubble. When I clicked connect it tried for a few seconds and then gave me an error asking me to make sure it was plugged in and turned on. Which of course it was.

Also just as an aside here, my specific focus motor is the Feathertouch Direct Drive motor. I have it highlighted in the attached screenshot.

Sounds really exciting. I look forward to the future.


Micheal Fields replied to the topic '10Micron Mount Modelling' in the forum. 3 months ago

I am going to let Michel answer you in more detail but essentially yes. The 10Micron has two states. Syncs refine a model and syncs update a model.

Starting with 3 base points which 10Micron mounts need as alignment points, much the same way that Celestron has 2 initial alignment points before you can add any more, but every point beyond the initial 3 counts as refine points. You can have up to 100 total where 3 are base points and 97 are refine points. The mount does the math internally where something else like T-Point does it externally in software on your computer. This allows the 10Micron mount to be fully modeled with nothing more than a cross-hair eye piece or DSLR with live view + cross-hairs and the hand controller.

So what these 3rd party modeling programs like Michel's does is automate the process so we can go have coffee. It slews to a base point, takes a image of the sky, plate solves it, and syncs. Since you select Syncs refine in the mount, it adds it as a new point. When you are done with lets say 45 you have chosen, you have a 42 refinement and 3 base point alignment. This is used by the 10Micron to adjust tracking. The 10Micron has absolute encoders and can make changes based on what it detects during the model. Anything that repeats can be modeled.
Sync align mode is for shifting/correcting an existing model. So if you have 40 points from the night before but maybe you rebalanced and moved your OTA in the saddle, you choose sync align and do one single plate solve/sync and it shifts/corrects/updates your existing model.

So what I am missing from the StellarMate and/Ekos etc is this ability to slew/solve/sync on a generated field of points. Where the following is necessary:
1) Software must tell the 10Micron if it is a refine point or a base point.
2) Software must tell the 10Micron if to set syncs refine or syncs align so it knows if it should be refining or updating.

Somewhat related the mount can also adjust its model and tracking based on refraction which can change when temps drop or raise. So some of these automated modeling softwars like Michel's have a way to interface with existing sources of weather information and time/gps updates and put that in the mount too. As having the correct time is important too.

With modeling and the ability to dither without a guiding I would be super excited about using this ekosystem :)

Sounds like its a maybe!


Micheal Fields replied to the topic 'Ask for non-guide dither setting in Ekos' in the forum. 3 months ago

If you consider the way Sequence Generator Pro handles this you will see it is under guiding set up where guide type has a selection called "Direct Mount Guiding" which essentially indicates the mount handles guiding itself. Then there is a dithering option that shows how much dithering you want to deal with.

Here is what it looks like. youtu.be/84UKgZs_VRA

I have been trying this out the last week and it is working perfectly.

My intention is to have all this installed on my Raspberry Pi 3 where it does everything I need so I don't have to bring a laptop. I have a light weight, low power method of imaging. Right now as it stands there are two things that are stopping me from going all-in with Ekos. 1) I need a way to do mount modeling which I am being told is being worked on currently YAY! and 2) dithering without guiding which you say you will work on at some point. Once both those things are accomplished I don't think I will need any other software to do it all.


Micheal Fields replied to the topic 'Ask for non-guide dither setting in Ekos' in the forum. 3 months ago

I would like to jump on this bandwagon as well. My 10Micron mount does not need guiding. SGP, CCD Auto Pilot, TSX all have the ability to do unguided dithering. Having the ability to do this and also set the amount of dither would be excellent. Low, medium, high, ultra-high or set by pixels or arc-seconds manually.


Micheal Fields replied to the topic 'StellarMate Astrophotography Gadget' in the forum. 3 months ago

Well the interesting avenue to persue is using Python. The Mount Wizzard modeling program is written in Python and I was just reading about INDI / Python and the Rasberry Pi. www.indilib.org/support/tutorials/166-in...on-raspberry-pi.html

So maybe the easier way to go about this is to have Michel, the developer of Mount Wizzard, put them together in some way where his Python program talks to Ekos and INDI.


Micheal Fields replied to the topic 'StellarMate Astrophotography Gadget' in the forum. 3 months ago

Unguided imaging is where it is at. That is why I have a 10Micron. To do unguided imaging you need to do a model of the sky. For very fast optics with a higher image scale you can get away with doing maybe 25 points. The max is 100 points. The way it works now is a 3rd party application communicates with SGP, MaximDL, TSX pro and perhaps others and it slews the mount all over the sky doing plate solves and syncing the image. Each sync adds a model point. Since it does it automatically you can go have coffee or do some observing while your mount models. When it is done you can do unguided imaging.

If you are in an observatory with a mount and OTA that will remain in place for a very long time this is not an issue. You would only need to do a model once and occasionally do a single sync to update the model. But if you are portable like I am then you do a model each time you set up. Therefore it is a bigger deal.

The only way I can see doing this without automation would be to manually slew to a star using Ekos then center it with the arrow keys and then do a sync. But if I did lets say 75 points to the model that will take quite a while.

Here is a newer 3rd part program written by someone else in Python. github.com/mworion/mountwizzard Here it is in action: www.youtube.com/watch?v=JMAfZoq8rBI

Thanks! I ordered the image file today and looking forward to using it. Thank you for taking the time to chat with me today. As soon as Amazon delivers the Raspberry I will dive in.

We talked a bit about 10Micron. I am happy to hear modeling is being discussed. That is really the only thing that will be a show stopper for me. I would have to use Windows/SGP/Model Creator to make the model but I need a windows PC to do that which defeats the purpose of the StellarMate and the Ekos system. I could do it manually but that would be very long and boring. I need automation :)
