Does it matter if you start up eqmod as the first driver or the last driver from commandline ??

Those figures seem to me be RA or DEC readings not temperature.. Just my 2 cents..

I just checked the fitsheader and it seems like the green square is at correct place, and I also checked with Stellarium and it is indeed correct.
I'm using a EQ8.

Hi there..
I've had it like that for a long time now but I never really cared about it but of course it would be nice to have it corrected.

Hi guys,
I just tried my SX cameras and none of them did connect, after downgrading to previous version it worked again..
So I think you can wait until next build or do a downgrade like this :
sudo dpkg -i /var/cache/apt/archives/indi-full_1.4~201703192003~ubuntu16.04.1_i386.deb
sudo dpkg -i /var/cache/apt/archives/libindi1_1.4.1+r2992~201703192155~ubuntu16.04.1_i386.deb
sudo dpkg -i /var/cache/apt/archives/libindi-data_1.4.1+r2992~201703192155~ubuntu16.04.1_all.deb
I'm not shure this is a correct way to do it but it worked..

Hi Jasem,

I just noticed that there is no difference between 0.001 or a 0.090 seconds of exposure ?? that is while using my SXVR-H9 cam.

Markku Siitonen replied to the topic 'Fitsheader format..' in the forum. 4 months ago

After some testing and googling I found that CRVAL1 , CRVAL2 , RADECSYS , CTYPE1 and CTYPE2 must be there.. maybe something more.
I hacked a bit with Python and set RADECSYS="FK5" , CTYPE1="RA---TAN" , CTYPE2="DEC---TAN" then SAOimage seemed to understand the sexadecimal coordinates but with a really strange aspect of space :) and that lead me to think that maybe CRVAL1 and CRVAL2 is also needed.

Yes, strange but true, and I couldn't find any explanation to this strange behavior of SAOimage..

Markku Siitonen created a new topic ' Fitsheader format..' in the forum. 4 months ago

Hi Jasem,

I just noticed that SAOimage doesn't understand the decimal format of RA/DEC so I wish there could be a choice of getting the sexadecimal or decimal (oldstyle / newstyle) format of the fitsheader somewhere in the fits configuration tab in KStars.

Hi Jean-Luc,

Now I know the reason :)
Thank you for explaining that, I'll do some more testing when weather permits but so far everything is working just fine.

Hi Jean-Luc,
As usual I thought I did something wrong :)
The RA PPEC works as it should so no problem there, but I'm a bit curious about why DEC PPEC is'nt working, according to HC manual there is only RA PPEC so why not for DEC ? my guess is that there is no need for that if the mount is correctly aligned but correct me if I'm wrong..
Thank you for your hard work!!

Hi Jean-Luc,
Sitting right now and testing :) Well, I don't see the "Worm period" changing at all, it just shows RA Period 439 all the time but if I switch off the Directions control in RA I can tell there is improvement.
One thing I noticed is that the "Aux. encoders, RA Steps" do change ? maybe that is normal because things get a bit worse when enabling the Aux. encoders.
Is is ok to have the DEC guiding active and just disable the RA guiding and still have the RA PPEC doing its stuff ??

Hi Jean-Luc,

I did some testing last night but how can I tell the difference between using RA PPEC or not using RA PPEC ??
It should be visible in the guide window but I could not see a big difference because the window timespan is a bit short.
Anyway, I post 2 images to show what it looks like.

Hi Jean-Luc,

That will be a really nice addition to Ekos :)
It looks like the weather will be good tomorrow night so I'll give it a try and see how it works.

Downloading the PPEC table could be useful for checking how good or bad the worm is and maybe also if there is a way to clear the PPEC table ??

Thank you for a great work!!
