dithering time

[Krawler14]

guiding with PHD2, my dither time is a minute and a half (roughly) is this normal? seems like its eating up a lot of capture time on me,  also have another concern, which may or may not be a dithering issue.. but after 2.5-3 hours on the same DSO I notice my FoV drifting, example- a star near the bottom edge of my FoV in my first sub , will migrate out of my FoV in a few hours. is this normal?  ( PA and guiding are pretty solid btw )

 

thanks for any help! id love to get my dithering time down. a minute and a half seems like a long time

I believe that your issue is with PHD and/or alignment.  It is my understanding that BYE waits until PHD says that the dithering is complete and the guiding has settled.

 

With good PA and well-tuned guide parameters, you should be able to go for several hours (until a meridian flip, or the object drops toward the horizon) without drifting more that a few pixels, if that.

 

You may benefit from asking the PHD folks about your issue.

Looks like you have a guiding issue, balance maybe?

 

Could also be backlash... Make your gear is a tab bit east heavy.

 

PHD does the dithering, BYE simply send the command and wait for PHD to confirm when it is done. 90 seconds is not uncommon.

 

Keep us posted.

Please do pursue with the OpenPHDGuiding.org Support Group.

 

But, if you can tell us a bit of Info about your Equipment (Scope, Mount, AutoGuider) it may allow one of us to make some additional Insight or Suggestion.

Also, what did your PHD2 Graph look like during one of the Guiding Sessions where you had issues with some Stars drifting out of the FOV??
