hi Rene,

the ideal exposure time depends on many factors that are not known by INDI/Ekos. Mainly SQM and some feature of the camera like QE, dark current, read noise, FW depth have impact on the optimal length of the exposure.

I would rather use simulators that available online or as excel file.
I even tried to write one for myself but my personal experience is that, despite the theoretical model being perfect, the uncertainty on some inputs is affecting the results so much that an empirical approach based on trial and error is more valuable.

hi Wolfgang,
to me it makes sense.
I'm thinking of a use case where the weather gets bad (warning) and the sequence is stopped and the shutter is closed but the cooler still on and mount not parked. If the weather gets worse (Alert / danger/*) mount is parked, camera warmed up and INDI stopped.

Are you thinking to place the logic (the steps) for suspend / resume and shutdown / start up in the Observatory on in the Scheduler? as you know i'm in favor of the Observatory because it could be used even if one is not using the Scheduler. For example if a standalone Capture is running.

* somewhere else in INDI / Ekos it has been used 'Danger' or other words instead of 'Alert' (e.g. in Weather interface). I think any word is fine but it should be kept the same all over the place.

hi Wolfgang,
I was wondering if the observatory status is useful also as a command to activate the whole observatory.
For RoR, it is redundant, they already have unpark to get the same result.
For domes, it could be dangerous to issue two commands (open shutter and unpark) at the same time. Actually would be more dangerous to do the opposite: close shutter and park.

I would leave the observatory status issuing no action, just showing the status. Any action should be managed by a more complete procedure that is customizable. Like: first unpark dome, wait 10sec, open shutter.
Again, this approach would make more sense in case of a shutdown than wake up.

hi Wolfgang,
Using Weather Watcher. But I can't recreate the status icon issue anymore. I will let you know if I understand the condition for this to happen.
Ferrante

PS: sent you a personal message on a related topic.

hi Wolfgang,
tested the latest version, attached a screenshot.
The park delay on Warning / Alerts works just fine and it's great! thanks.
Minor issues:
- on startup the Weather status icon is not shown (see picture). But when status changes the icon is back.
- If the dome doesn't have shutter, the shutter controls on the right shouldn't be visible.
- I rather prefer a delay in seconds.

I'll write you a PM later.

hi Wolfgang,
I've a roll of roof, and yes, Observatory works as expected with mine: unpark opens, park closes (*).
Moreover, opening is inhibited if weather is not ok.

(*) as you know there was recently a discussion whether or not this was the right approach.

hi Sterne Jaeger,

I cloned the repository and installed in my remote observatory and can confirm it works with 'real' devices too.
Weather status is read from weather station and changes status accordingly.
Dome (roof in my case) parks and unparks. Attached a screenshot when roof was unparking / opening.

Good job! thanks.
Ferrante
