Yes, this "bias frames open shutter" issue is still there in the newest version as well. Not too bad to work around using dark frame type, but would be nice to have it fixed too, just got bitten by it, fortunately noticed it after a couple of frames and remembered this. Also for example PixInsight detects the frame type so it would be easier if it was correct in the fits file.

Thank you, this is very informative as I just received my ScopeDome 2m dome yesterday and am writing INDI driver for it. I think I'll have enough problems without these math issues too :)

In case someone else is interested as well I made a simple Python 3 script that converts CSV format observing list exported from DSO Browser ( dso-browser.com/ ) to an Ekos schedule. It takes a sequence file, a template schedule file and the CSV and outputs a schedule with all the targets. The template schedule should have one job which will then be duplicated for each target. The script can be downloaded from s2.org/~jpaana/csv_to_esl.py

I've used pretty much every version from 1.12 to 1.23 so far, the difference might be that we are using ARM driver on Raspberry Pi and you seem to use Intel. I had similar issues with Cloudmaker's USB Focus V3 driver, which didn't work on ARM but worked fine on Intel and it looked like uninitialized variables or something as the settings were full of garbage. Could be that the frame type isn't always properly initialized on ARM so it doesn't quite work until set to a different value and back. Just a guess though :)

I've had similar problems for a while as well that the camera doesn't always open the shutter then taking light frames. The workaround that has worked pretty well is to take one dark frame at the beginning of the session and it usually works fine after that. Ie. set frame type to dark, take 1 second exposure, switch back to light frame type. Not ideal especially with Ekos scheduler, but better than nothing.

Jarno Paananen replied to the topic 'Image counter for flats not counting' in the forum. 5 months ago

I think I had something similar with light frames as well recently where the first frame was being overwritten due to the counter not incrementing. When I added time stamp to the file name I could get all the frames but they are all numbered 001 like this:
Light_OIII_0.500_secs_2017-05-17T00-24-54_001.fits
Light_OIII_0.500_secs_2017-05-17T00-25-08_001.fits
Light_OIII_0.500_secs_2017-05-17T00-25-22_001.fits

I had the same issue earlier in the spring and just made a quick hack for my setup and commented out this part in 3rdparty/indi-gpsd/gps_driver.cpp around line 194:

    // adjust offset for DST
    if (local->tm_isdst)
        offset -= 1;
I don't know what the point of this code is as the offset is what it is with DST included.

Looks like SD card corruption, Linux remounts the file system read-only if it encounters errors on the card, running "dmesg" command should show if that is the case.

I've recently played with ASUS Tinker Board ( www.asus.com/uk/Single-Board-Computer/Tinker-Board/overview/ ) which ticks some of those boxes (dedicated GigE, 2GB DDR3), unfortunately it's only USB 2 and the OS support is still fairly bad. The official supported OS is Debian Jessie, though I've upgraded to current unstable to be able to compile KStars on it. More memory and faster SD make it feel quite a bit faster than RPi 3 so I hope to be able to replace it at some point.

knro wrote: No that makes it wrong. "-00h 00m 02s" is 2 seconds, not 2 arcseconds, but is equal to 30 arcseconds. It is 33 because the dRA display rounds it off, it is in fact "-00h 00m 02.2s".


Ok, then it's just that the RA in simulator has much larger errors as the code calculates both in the same way with degrees and the / 15 made the error more symmetric. EQMod simulator seems to have slightly smaller error so it passes with defaults. As said this is only with the simulator but I've had the similar issue on my scope as well that the slew to target routine tries to make miniscule changes even though the target is spot on in the center already. I increased accuracy tolerance to 50 and it seems to do it less often. Could be my mount or something, but I'd think HEQ5 is pretty accurate in that sense. Then again I'm at fairly high latitude (61.5) and quite often imaging near NCP where plate solving seems to be more challenging.
