TOPIC: remote solver | unable to solve

remote solver | unable to solve 1 week 2 days ago #27268

I have amended the solve-field attributes with -d 31-40 and it solves much quicker. However, how can I possibly know this value on new pictures?

from the solve-field man page:

-d, --depth number or range
Number of field objects to look at, or range of numbers; 1 is the brightest star,
so "-d 10" or "-d 1-10" mean look at the top ten brightest stars only.

Should be there in minute or so. The NEW file is the one with PIXSIZE added. The normal file is the one from SGP. You'll notice they use different header data for pixel size. Y and X.


So I investigated the FITS file generated by SGP and it was using a non-standard FITS keyword (SCALE) that is not officially defined by the standard. WIth the scale keyword, it's possible to use the "app" parameter in astrometry. So long story short, I added support for SCALE keyword in KStars in the next release.

I’m also having almost no luck plate solving. Is their anything else settings wise we should be doing to improve the chance of plate solving working?

What's your problem specifically? log? The above fix was for solving specific SGP generated FITS files.

It's just timing out and not resolving. Attached is some screen shots of the astrometry configuration and a log file that. The log file is big though, what "text" should I be looking for?

Under Logs, enable the following: INDI + Mount + Align + CCD.

If the file is large, zip it first or post a link to it if you cannot attach it. Is your FOV indicated as 0x0 or already have your correct FOV value?

I think I hit some size limits and the screen shots and logs didn't upload.....

I have had some success as I had the chance to test some other settings on the weekend. I have a pretty wide FOV on my current setup (8" EdgeHD with Hyperstar with a ZWO 1600MC Cool Pro) and I had a *lot* more success with plate solving when I set the binning to 2x2 (from 1x1). It completely flipped my results around to solving pretty much every time I tried it. So it must have been related to sending an image with too big a FOV. At least, that's the only setting I changed that made an immediate difference, and it improved the results considerably.

Does that sound right?

PS Also, while I've got Stellarmate, I'm setting it to resolve remotely on my laptop and not on the Stellarmate itself.

Here are some of screen shots from when I having problems consistently plate solving as an FYI.

Here is a link to the screen shots and the logs in Box as I can't seem to attach screen shots in the forum

app.box.com/s/6ztprhy5vw36yeoaqracfbq0ecc1tjhz

While I'm having more success now, it'd still be good to try and get to the bottom of what I was doing wrong to help others and myself in the future.

Thanks in advance, Craig

There isn't enough in the logs to say why it failed. I might make Ekos try to ekos the maximum binning by default for new users. I use 4x4 all the time on my QSI583

Ah, thank you, that's good advice Jasem. I hope to have the scope out in the next day or two and will test 4x4 as well as 2x2 again. Sounds like 2x2 as a default setting is a good place to start at a minimum. I'll add that to my checklist.

One question, there are tons of settings in EKOS. Can I just take a snap shot of them all and once connected have them applied, including the devices themselves??? For example, in my ZWO camera, every time I connect I have to go in there and remember to set it to 16bit and not the 8bit default. I lost a whole night's data because I forgot this setting on my 1st time out. Binning settings would be something similar here. So along with the base profile you create in EKOS, be able to store *all* these settings in one place and have them re-apply when you are connecting devices and other settings in the focuser/solver/equipment etc.

The other plus, for support, is that I could simply then create this settings file and it'd make troubleshooting issues considerably easier too I am thinking.
