Hi,

to avoid Ekos asking you confirmation, best route is, in INDI control panel, "Manual Fiter" tab:

1 - set your filter
2 - press button "Filter is set"

Provided that in your sequences, the filter is the same you set at point 1, you'll not be asked for confirmation anymore.

Hope this helps

Doug, my English is propbably bad. I didn't say pixel size is necessarily part of the equation: given that you can find CFZ equations that take pixel size into consideration when sensors are involved, I only said that, if needed we know pixel size; the whole point was to say that CFZ should be calculated automatically by code, not entered by the user (maybe you already said that and I missed it). If that equation is better than another one, I can't say and I won't debate about it.
About microns per motor step, we agree. Again, I was only saying that user should be encouraged to measure the focuser travel over the highest possible number of steps, to minimize the inevitable measure error.

Since f/ratio is known, "Critical focus zone in micron" could be calculated automatically (also with ccd-corrected formulae since we know sensor pixel size too). So only needed parameters are "Microns per motor step" and "Step size (CFZ units)". For "microns per motor step", I think the best approach for non technical users is to provide them with two fields: "maximum focuser travel (mm)" and "maximum steps (for total focuser trave)" and let the code do the division. This suggests the users to measure the max travel and not, to say, the needed steps to travel 1 cm, which is useful to reduce impact of inevitable measure error.

My 10 cents.

Maybe you already know, but if you need to establish exposure time to reach target ADU, you can use the "Calibrate" button that enables when you choose "Flat" for image type in capture tab.Then Ekos will automatically find correct exposure before taking your flat sequence.

Hope this helps.

Saw same behaviour with my GEM45. I will check again, purging saved driver configuration and restarting from scratch.

I think "Out step multiple" set to 2 is too few: you have only two shots on the right-hand side of the V. Have you tried with a value of 3 or 4?
My two cents.

I use an iOptron GEM45 with the iOptronV3 driver and it doesn't need any alignment to be fully utilized from Ekos.

Hi,

you can uncheck "Remember job progress" in Ekos Scheduler Configuration  

 and maybe check Timestamp in images file names to avoid the need to remove images from the folder.
Hope this helps.

Hi,

Radek did the same thing inside its "Astroberry-DIY" drivers collection. You can find it here: github.com/rkaczorek/astroberry-diy and look in astroberry_relays .h and .cpp.
Hope this helps.

You're right: those serial cable components are vital. A remote trigger is nothing more complex than "closing a switch" (in fact you can do it with your finger tip :D), something than a standard PC is "electronically" not capable of, at least without a dedicated circuit. In particular, USB signals are totally different animals.
DIY guys use a pre-made USB-to-serial cable (that's not simply "a cable", since it contains a small circuit inside itself) to obtain a simple "on/off" signal at one of the serial "pins", that can be driven through some softwate instruction; then add the necessary circuit (the components you said) to let it become a "switch". Eventually it becomes a "software controlled switch", that's exactly what's needed for a shutter release command.
Luckily, those additional circuits are very simple, and can be realized without a PCB, needing only some soldering skills.
Lacking the skills, I understand that could be scary, but not impossible.
Otherwise, you could find someone near you that's able to help you building it.

Sorry to carry the bad news, but hope to have helped you clarify things a bit.
