Hi Jasem,

I do not know how to apply that routine for my use case. I understand that you use a motorized rotator? I have to rotate manually, i.e. loosen the clamping of drawtube or camera, rotate and tighten again.
Ekos ideally should prompt me how to rotate, let me acknowledge when finished, check against a new capture and reiterate until within a given deviation.

Here is the procedure SGP implements using a Manual Rotator as a device: www.mainsequencesoftware.com/Content/SGP...o.html?Rotators.html

It is 1.

Or even simpler: add another edit box which displays the difference in degrees between the last image that had been solved using "load and slew" and the last image that has been taken by the alignment module (as there is no way to prevent another image taken anyway when using "load and slew").

The other way would be to add a radiobox "solve only" so the user can just load and solve, without ekos trying to actually get there. That at least would remove the timing component out of reading the rotation.

I have just been looking at the alignment module code, it seems there is support for rotators, so I guess it would also possible just to have an INDI-driver implementing a manual focuser, prompting the user to rotate?

Hi,

I think rotation with regards to (re-)framing could be improved upon. What I am currently doing:

- Solve an image in the alignment module
- Watch for the resulting angle to appear in the rot field
- Quickly take note before it gets overwritten by the solution of the next capture
- Subtract the values and rotate my imaging train/cmaera by the resulting amount

Sequence Generator Pro and N.I.N.A. both offer a manual focuser, which upon solving and determining the current FOV, prompts the user to rotate the camera by the correct amount. So basically what I am doing manually.

I could do without the prompt , but having the difference in rotation of a solved image and the current FOV in a more permanent fashion would be very nice. I am sitting in front of the screen like a hawk, waiting for the solution before it gets overwritten by the next capture ;)
The same goes for the KStars windows where the solved FOV is only displayed until a new capture is solved. Being able to have a permanent FOV indicator for the manually loaded and solved image woudl be nice, too.

Or is my approach wrong and the information I am looking for is somewhere else? At least I didn't get any replies on my query here: indilib.org/forum/general/5933-re-framing-and-rotating.html

Thanks

If you don't like KDE or think it is too sluggish on the PI (and I agree), coinsider using something else. For the adventurous, and I explicitly do not recommend this for anyone not knowing his or her way around Ubuntu or Linux in general:

sudo apt install mate-desktop-environment

There's basically every desktop environment or windows manager available... Stellarmate seems to be based on KDE neon which is based on some Ubuntu LTS release.

I found neon not to be particularily suited for productive use (I used it before for non-astro-related tasks), it is the KDE showcase distro, and IMHO the only thing it has going for it is an up-to-date KDE. Anyway. Before trying anything, make a backup of your SD card.

freiform replied to the topic 'Wrong gain in FITS header.' in the forum. 3 weeks ago

As this is a new camera and it was the first image with on a new target (IC434) that is containing a bright star (Alnitak), I cannot judge the gain of image visually. Well, I suppose the background might give it away. I'll look into that.

To the question when to actually refocus, I think if you realign before each step of a sequence, either do the alignment at the end of the last step, i.e. the last filter is still in focus, or before aligning with the new filter, and you can then use this focus for capturing. Although this might cause problems if a sequence is aborted/stopped and resumed at a later point and woudl have to be caught programmatically, i.e. 'always focus on teh first step'.
If align is disabled, you can just focus after a filter is changed or a certain time has passed, or temperature changes (is this implemented?) or HFR runs away.
Theoretically, I do not think that refocus should be mandatory for every step just because it's selected globally in the sequence tab. Consider bright cores of galaxies or nabulae with high dynamic range where one wants different expsure lengths for the same filter. Why refocus? It certainly won't hurt, and the time lost really is of little to no consequence, but making this conditional probably adds unnecessary complexity in both programming and usage. Just considering whether or not to, you just might want skip between certain steps.

Another thing is that I do not think of EKOS' focus functions as especially robust, so I personally would not want to have unnecesarry focusing runs that might or might not cause problems, potentially ruining an unattended imaging run ;)

I configured the sequence so that after each filter change an autofocus should be performed: I had Focus selected in the Scheduler tab and activated Auto Focus for each filter in the filter settings.

freiform replied to the topic 'Wrong gain in FITS header.' in the forum. 3 weeks ago

Hi Hy, my sequence contained three filter changes with AF after each change. I use 3.3.6 pulled likely before Oct 5. I normally use 200 for narrowband exposures, 0 for luminance and 335 for AF.

So the gain in the FITS is the actual gain used for the exposure? There goes 4 hours of data :(

Hi,

last night I used the scheduler for the first time. I created a sequence fir IC434 consisting of various narrowband captures and used that sequence in the scheduler. everything worked flawlessly, but the FITS headers of my images show a gain of 335 (which I use for auto-focusing) instead of the 200 I configured for the light-frames. Looking at the esq-file, it says

<OneNumber name='Gain'>200</OneNumber>
for all entries of the sequence.

This looks like a bug, or am I doing something wrong?

Oh, that problem can be easily solved. If you have a proper router (I use it on a FritzBox), just set up a VPN. This let's you login into your home network and have full access, just as your local devices. I use it to access e.g. my NAS when at the office or on the road. I also understand that the Ekos Live Service also lets you access your gear from anywhere, I have never tried it, though.

I only saw your initial answer, not the second one with the video. Anyway, I have seen the video and it didn't answer the questions I was asking. It just covers setup and basic capture.

freiform replied to the topic 'Stellarmate App - What can it do?' in the forum. 3 weeks ago

Hi, thank you fo the detailed answer, much appreciated. Unfortunately not quite on point ;).

I was asking about the mobile app. I am already using a custom INDI/EKOS installation on my Laptop, and I suppose that StellarMate doesn't expand EKOS base functionality beyond what I already have.

I have an EQMod enabled Vixen GP, an ASI183mm pro, a small guiding system with an ASI 120mm, the ZWO filter wheel and a custom focuser. All of which work with my current INDI/EKOS setup.

My question was with regards to how much of EKOS' functionally is exposed through the mobile app? How much of my setup can I control? How do I select targets? How does it interface with mobile planetarium apps? Or is it just a fancy interface that let's me check if everything is still running smoothly from my couch?

freiform created a new topic ' (Re-)Framing and Rotating' in the forum. 3 weeks ago

Hi,

I often want to revisit an object to gather more data or just continue capturing after having modified or changed the optical train for whatever reason.

Getting to same position is working good using Solve & Slew, but how do you handle rotation? SGP and N.I.N.A for example offer a nice interface to a manual rotator, i.e. they calculate the angle difference and prompt you to rotate the camera manually by a given amount. You acknowledge you input and the process loops until the frame is within the specified range.

How can I do this reliably with EKOS? There is the Field Rot in Solution Coordinates in the Solver/Alignment Module, but this doen't seem to indicate the actual angle relative to the angle of the solved image.
