That sounds like a last resort, but if that works I guess I can set it all up again. Thanks for the reply

Jim created a new topic ' Built in guider won't calibrate' in the forum. 2 days ago

Most recent kstars/ekos bleeding on both ends. Mount is a NUC that has been running INDI for quite some time, both running Fedora Linux.

When I click the calibrate button, the first image is captured, and it says it is drifting RA forward, but it does nothing after. No new images are captured and it just hangs.

Logs attached.

I operate over wifi with a 16Mbps camera, and it is not just phd2 that has the issue. The built in guider is subject to this pause as well. I get around it by storing the images locally to the scope computer, as mentioned. I then use rsync to bring the images across to my computer in the house where I do any processing (where it is warm!).

One thing of interest, .fits files are very compressible. I use the compression flag on rsync, and I am able to transfer complete batches of files with rsync while normal operations are still under-way. Compression takes cpu power of course, so not sure how it would run on an early Pi, but the newer multi-core machines should be fine. Would it be possible to add an option to compress the stream with gzip or equivalent? This could make everyone's downloads 3x-4x faster on bandwidth limited connections. If stream compression can be achieved, the receiver would uncompress the stream and use the data as normal.

Here is an example file to show compression:

Jim created a new topic ' usability: Please remember the filter in use on the CCD tab' in the forum. 7 days ago

A small request. Ekos does a nice job of remembering the camera configuration to use when switching to the Solver tab. It switches to L filter, binning, exposure time, etc. Saves a lot of time. Please also do this for the CCD tab. The CCD tab does remember exposure time, but does not revert the filter. Last night I ended up capturing 5 minute L exposures many times when switching back to the CCD tab. They don't work so well when you were hoping for Ha. :whistle:

I realize this is my fault with being new to automatic filter wheels, but it would have saved me a lot of time, so maybe could save somebody else too.

Thanks!

btw, Ekos/INDI/kstars works flawlessly all night long last night. It was a wonderful experience.

This is probably a kstars request,.

Does the option exist and I have not found it?

On the subject of changing the exposure settings for live video, when you make a setting change, you then have to first do a preview before the live video will pick up the settings. I think I posted about this some time back, but since I found the work around, it wasn't high on the list to look at further.

Jim replied to the topic 'Re:Are there situations where polar alignment does not work?' in the forum. 4 weeks ago

That is what I do. I have a pier now as well, but I do check it now and then from the comfort of my house :)
I have seen on occasion what @anofeles is seeing where after running back the other direction, the mount is off about the same distance again. Is this just an iterative thing and I should do another round of aligning in the other direction? When it does this, it is off 2-3 arc minutes. I usually just chalk it up to my mount being a lesser expensive model and go on about guiding, but if I can get it closer, I would sure want to.
@knro how close to 0 does your EQ8 get you?

Jim replied to the topic 'Re:Align tab mount model 2nd star captures too quickly' in the forum. 4 weeks ago

That is both good and bad. Good because that is how we would expect it to work, but then what is going on with my setup I wonder. I will have to see when it is doing the capture. Is it capturing before it starts to slew because it has a successful timer expiration (from the first slew)? Or is it at the end of the slew in which case, I should try an even longer settle.
I cannot try tonight, but looks like tomorrow night might be good.

Jim replied to the topic 'Eqmod alignment' in the forum. 4 weeks ago

I guess if you want to call voltage shifting TTL an electronics box, you would be correct. It is more than just a simple pass-through. One such provider that I have used with great luck is Shoestring Astronomy: www.store.shoestringastronomy.com/index.htm - there are others, just a happy customer. It is still simpler than a full hand controller with its extra connections.

Jim replied to the topic 'Re:Align tab mount model 2nd star captures too quickly' in the forum. 4 weeks ago

It is indeed a great tool. It does exactly as it is designed to any my go-to ability after using it puts things on both sides of the meridian right where they need to be. It seems like this might just be a simple request to not attempt the capture until the the settle time has expired after a slew? This might just be a missing function of the module?

Thanks for putting it together. Very handy.

Once I got the cable, I safely packed away the hand controller in a box and put it on a shelf as a backup if my cable were to ever go bad. I did use it before the cable arrived, so I know I can use the synscan interface as well, but there is nothing to be scared of with replacing it with a good quality cable. In complex setups, one less piece of electronics and cable connections is not a bad thing.
