Hi knro:

How about using the exposure time, read out time and delay time settings to estimate the time to meridian, though this method still has its limitation as download time cannot be predicted.

Hi knro, looks like many people came across with this problem, is there any plan to solve it ?

Do you plan to implement the waiting feature in the next version ?

I agree that the imaging data on meridian is quite important. I do photometric work and know that the data from meridian usually has the best quality due to a lower airmass.

However, I will still be grateful if you can add an option to flip immediately and pause the exposure if the duration is longer than the time to meridian. Since I am working with a remote telescope, I must keep the telescope in a safe position as much as possible.

In addition, shooting a target with a exposure duration longer than 600s is quite common for me as I use Strömgren u filter to measure the Balmer jump, where the light flux is quite low in near UV (due to the Balmer jump the stellar flux is significantly lower and the atmosphere absorb more light in NUV). It is necessary to get a longer exposure to achieve the same SNR with those broad band system.

starrybird created a new topic ' Abort current exposure when hour angle is greater than 0' in the forum. 4 months ago

Sorry I not sure where to post a feature request. So I post another one here.

The original one: www.indilib.org/forum/development/3531-a...-greater-than-0.html

Last night, I tested the meridian flip in Ekos and found a problem.

I set up a series exposures with duration 900s and the auto meridian flip was enable, then I chose a target which was near the meridian. When the hour angle was greater than 0 (this is the default value) , the scope would not flip automatically until the current exposure was finished.

In my opinion, the current exposure should be abort and dropped when hour angle is greater than 0, then perform the meridian flip immediately and restart the exposure which has been abort before. The reason is that if an exposure is very long (For example 3600s or more, my CCD can do such a long time exposure), the scope cannot track accurately when hour angle is greater than 0. In addition, the scope is in dangerous position and it might hit the tripod.

Based on my view, I urge that to stop current exposure and perform meridian flip in Ekos when auto flip is enabled and telescope hour angle is greater than 0. Then restart the exposure which has stopped before.

Does anyone come across the same problem with me ?

starrybird created a new topic ' Add python script execution when auto guiding is failed in Ekos' in the forum. 4 months ago

Some of the softwares such as SGP supports notification via email when auto guiding is failed. I think this feature is useful when you set up an automatic observation during the night. My way is much simple: just add a python script execution when auto guiding is failed. Then I can write my own script to notify me something went wrong.

Moreover, it will be nice if script execution can be added to other modules (focus, capture, alignment etc) when things go wrong. For an autonomous observation, anything goes wrong should be notified to the observer asap. This will help the observer to deal with the problem immediately without wasting the time.

For the script execution, I think it can be implemented in schedule module next to the "steps". For example, if guide module is activated and a script is applied, when auto guiding is failed, the script will be executed.

Any view on this feature?

starrybird created a new topic ' Problem with PyIndi client' in the forum. 4 months ago

I am writing a simple client to control my mount via pyindi-client and I just encountered 2 problem.

Problem 1 is I don't know how to obtain the info message generated by driver?

Problem 2: When I test my client with EqMod Mount and the limit is enabled (goto, track and slew), however, the mount will not stop event if it is out of limit and warning can be seen from EKOS's INDI menu. It seems that the TimerHit function is not called but I don't know the reason for that.

Hope someone can give some help with these 2 problems.

I noticed that his settle time is the delay after dithering and before guide resuming. My expectation is the delay after guide resuming. I am not very sure that settle time is the delay after guide resuming.

Currently Ekos supports setting settle time in align module, but there's no similar setting in guide module.

After guiding is started or resumed from dithering, it is better to wait several seconds before capturing the next light frame. So I hope that there is an option for this purpose in guide module: a settle down time setting in guide module. When settle down time is greater than 0 s, a delay should be added before capturing the next light frame after guiding is started or resumed from dithering.

Though I can set a delay in capture module, I think adding settle down time setting in guide module will make things more clear.

Hi knro:

Thanks for adding the support in the mount control menu.

You mentioned that the J2000 stuff would ONLY be visible in the mount control panel and no where outside that, can you tell me the reason for that?

starrybird created a new topic ' Add J2000 coordinate supoort in Ekos and INDI' in the forum. 6 months ago

From this topic I knew that both KStars and INDI use JNOW coordinate. However, many catalogs and online databases provide J2000 coordinate of an object. The only place I can use J2000 coordinate is in schedule module. For normal telescope slewing, I must enter JNOW coordinate in mount control menu. One possible way is to add an option for user to select which type of coordinates are entered. Is there any plan to implement J2000 coordinate input in mount control in Ekos?

JNOW coordinates are displayed in both INDI and Ekos, I wish there's an option to select which type of coordinate to display (J2000 or JNOW). Is it hard to implement such feature?
