Should PHD2 still dither Dec if Dec Guide Mode is not set to Auto?

[mj.w...@gmail.com]

Hi,

PHD2 Guide Log attached

In Log Section 4, with the Dec Guide Mode set to Auto, there are two instances of dithers on both axis. As you can see the Dec performance was poor, due to stiction on the axis I believe, so I set Dec Guide Mode to North.

In Log Section 5 I realised I should be guiding Dec South, so I switched Dec to South at 23:42 and Dec guiding improved. Note however that in North and South modes  the dithers are only in RA.

In Log Section 6 all the dithers are in RA only except the last, where I tried setting the Dec Guide Mode to Auto a few seconds before the dither command. I was lucky to get that one in, because the clouds then rolled in and I packed up for the night.

(Note the dither commands are initiated by PHDMax software - it detects a new Raw file arriving in the Save folder and commands PHD2 to dither)

Thanks

Hi Michael.  To answer the question in your subject line, PHD2 may temporarily switch to bi-directional Dec guiding in order to perform a dither.  But that will only be done if the client application has specified settling parameters and RA-only isn’t set as a dithering constraint.  We’d need to see your debug log file to see what command PHDMax sent – it may not be sending settling params to PHD2, perhaps handling settling on its own.

 

Regards,

Bruce

The Fail log wouldn't go with the Debug log

[bw_msgboard]

Hi Michael.  Judging from the debug log, PHDMax is using the old-style server interface, the same as the one in PHD1.  That interface doesn’t provide any way for the client app to specify settling parameters.  So as I said in the earlier message, that means dithering would be RA-only unless Dec Mode is auto.  I just looked quickly at the PHDMax web site, and my impression is that it’s quite old and probably hasn’t been updated to stay current with PHD2.  Depending on what other software you’re using – notably which imaging app – you can probably find a better solution for dithering.

[bw_msgboard]

Just for future reference, this isn’t actually a log file – it’s an automatically generated capture of your guide image when the PHD2 auto-select of a star fails.  We do that to help with product support.  So you may find these in your logging directory but you can ignore them unless you’re having ongoing problems with auto-select.  They will be automatically removed on a scheduled basis so they won’t consume much disk space.  In this particular case, it was a very noisy image with a high background level, so the SNR was probably too low.

 

Cheers,

Bruce

Thanks Bruce

Well I usually guide with Dec in Auto, only last night at low Dec (M17) was the mount unhappy.

There's DitherMaster too, but I haven't come across any other free software that dithers or incorporates dither - Canon Utilities takes care of the imaging.

Yes the SNR was low at the start of the session last night, the sky appeared clear but there were sneaky little clouds spoiling things.

"You can't win, you post a guide log and no, they want a debug log......."  :->

Seriously, wonderful service from you guys.

Michael

[bw_msgboard]

You might want to take a look at Sequence Generator Pro, it does a very good job of using PHD2 for guiding.  And there is a free “Lite” version that probably handles everything you’re doing now.  Or if you use an imaging app that is capable of running a batch or script after an exposure is completed, you can use the PHD_Dither package from our web site.

 

Have fun,

Bruce

Hi. OK, so if I set DEC guide unidirectional and I'm using APT to dither, will PHD2 dither both axes? IOW, does APT send the required information to PHD2 for a 2 axis dither?

TIA

Hi Steve,

PHD2 will ordinarily dither both axes when you have un-directional dec guide mode selected (North or South).  The exceptions would be if a) you selected the "dither RA only" option in the brain, or b) if APT explicitly tells phd2 to dither RA-only. I doubt APT would be doing that, but we could tell for sure by looking in the PHD2 Debug Log.

Hi Andy
Here's a Debug Log *EDIT: Can't upload the complete debug log ATM. Is the snippet enough to tell?

The reason I ask is that the last discussion we had -I was getting streaking as a result of RA dither only with unidirectional DEC- was when I was recommended Bruce's Dither app as the only way to dither both axes with unidirectional DEC.

 You advised, 'PHD2 knows not to dither Dec when dec guide mode is North or South; it will only dither RA. When Dec mode is Auto dither will be in any direction unless you have the "dither RA only" option checked.'

That was in December 2016. Has the behaviour has changed since then? I have 2.6.3dev7.
TIA,
Steve

Here's a Debug Log *EDIT: Can't upload the complete debug log ATM. Is the snippet enough to tell?

yes, that is enough to show that the app is using the old PHD1-style interface which has no way to indicate RA-only, so the only way you'll get RA-only is if you have the RA-only option selected in PHD2, but see below.

 You advised, 'PHD2 knows not to dither Dec when dec guide mode is North or South; it will only dither RA. When Dec mode is Auto dither will be in any direction unless you have the "dither RA only" option checked.'

That was in December 2016. Has the behaviour has changed since then?

There was a change in 2.6.3 where PHD2 will dither both axes and switch to bi-directional guide mode until the dither settles. However ... this does not apply for apps like APT that are still using the old PHD1 interface because with those apps PHD2 has no idea when settling is done and does know when to switch back to uni-directional guiding. So unfortunately for those apps PHD2 does not dither both axes and it dithers RA only always when dec guide mode is N or S.

Hi Andy,

I'm one of the authors of APT. Implementing native support for PHD is in our plans. However I'm wondering if PHD2 knows when the dithering is finished? If it knows it will be good automatically to switch back to uni-directional guiding. This will give possibility to all programs that still use PHD1 protocol to be compatible with the new features of PHD2 :)

Regards,

Ivo

Hi Ivo,

PHD2 uses the criteria passed in by the imaging app to determine when settling is done.  The imaging app tells PHD2 to dither, and includes the settling criteria in the request (settle is done when guide error stays below P pixels for T seconds).  While settling, PHD2 sends status messages to the app, and when settling is done it sends a final status (success/failure).

Feel free to contact me if there is any other info you need regarding the PHD2 interface, or if there are any missing features in the interface that would be useful for APT.
