dither every few exposures

[Wei-Hao Wang]

Hi,

I apologize if a related topic had been discussed before.

I just wonder if PHD2 can implement a function to dither every N frames,

instead of dithering after every exposure.  This is very useful if the

photographer is conducting many short exposures (lucky imaging, for

example).

Generally speaking, this should be a function of the imaging program.

The program that controls the camera can issue a dither command to

PHD2 after every N exposures.  But the truth is, not every imaging program

has this capability.  We may of course insist that this is imaging program's

responsibility, for sure.  Or, we may do something in PHD2 to enable this

even if the imaging program does not make any change.

I think a possible method is for PHD2 to ignore the 1st to (N-1)-th dither 

commands (or simply send a signal back to indicate that dithering is done, 

although actually nothing is done), and only actually do the dithering for 

the N-th dither command, and so on.  This way, PHD2 can have the capability

regardless which imaging program it is (as long as it has the basic 

dithering capability).

Cheers,

Wei-Hao

Hi Wei-Hao.  This really isn't the sort of thing we want to do and I think you'd be better off finding a more capable sequence manager app.  There are plenty to choose from, all of the ones I'm familiar with can do this, and NINA is free.

Good luck,

Bruce
