Andrew Burwell replied to the topic 'Ekos Alignment module tries to solve dark frame' in the forum. 2 weeks ago

Is it possible to build a dark master for the guide scope, and save it to the proper folder for selection? Or, if there were a way to create the dark image from the settings menu instead of from the first time use of the guide scope? I think either of those methods might be preferable.

Andrew Burwell replied to the topic 'Flats not capturing???' in the forum. 1 month ago

I have the same issue on MacOS. Flats fail with automated ADU value, then after it captures the first one, EKOS crashes. Is there a way to grab the nightly for MacOS? Or publish the fixes to the next version. :)

Andrew Burwell replied to the topic 'Re:Resume guiding after clouds needs a plate solve action' in the forum. 1 month ago

I ran the scheduler last night to capture a set of frames, and for the most part it worked after clouds came by. However, it wouldn't wait for the mount to slew before attempting to capture and solve the current location. Since the mount was moving it would either fail, or think it was located somewhere it wasn't, and it kept screwing up the alignment. I had to reset the mount location, delete out the failed solves, and resolve to mark it's current position before continuing the sequence again.

I had never thought about using the scheduler like that and breaking up the session into smaller chunks. It's an interesting solution.

How about this possible scenario: What if when using the scheduler and guiding is lost, an alignment routine is run. That alignment routine will continually fail until the clouds are clear. It could continue running that routine until it gets a clear shot of the sky, and the mount corrects its position. Once it passes the alignment routine and is within the threshold of accuracy for alignment, it resumes guiding and capturing frames.

This might be a better option than basing the failure and alignment routine on an arbitrary amount of time.

I was only using the capture module.

I connected equipment. I had plate solved a few times to get the mount accuracy tuned in, picked a target and plate solved again, auto focused, started guiding, then added about 200 3 min frames to the capture module and started the process going for the night. Meridian flip went off without a hitch, plate solving re-centered the object. About frame 160 clouds rolled in guiding was lost for a few minutes on and off as the clouds passed. When it finally cleared of all clouds target was off center, and the rest of the frames were like this until I stopped the process in the morning.

After a full nights session, about 4am clouds rolled in briefly, during this time something happened to guiding when it stopped and later resumed. It picked up a new guide star, and the scope shifted a few degrees off for some reason. Because of this, I had about 2 hours of frames where my object was no longer centered. Is there any way to trigger a new sync and goto on the scope after it's lost guiding to ensure it resumes back in the same spot after the clouds go away?

Andrew Burwell replied to the topic 'What's next for EKOS?' in the forum. 2 months ago

I'm not convinced Trevor is the key to getting the word out. This community needs to be posting about their own successes on the various astronomy forums and their own websites. If people only post here, word does not get out beyond the community already using it. As people begin to see the successes others are having, they will be willing to give the software their attention.

As for documentation. A WIKI style system where users can contribute would be great. The wiki could be subdivided by EKOS panels, and then sections within those panels, and there could be another area which provides walkthroughs in setting up your equipment, first time use, recommended order of operations, remote operations, etc.

I've written a few articles on my own site, and would be willing to contribute this content where applicable.
