Re: Mach2 Unguided testing continues
I haven't figured out yet how I could take advantage of this and still be able to dither frames.
You can dither all you want. That does not affect the custom rates that are calculated and applied to follow the actual sky motion above you.
Think of it this way: If you have Sidereal rate set, but it is slightly too fast and causes stars to streak in a time exposure, you could theoretically slow the rate down so that it matches the motion of the stars that you are imaging. Dither moves the next frame over a few pixels but does not change that tracking rate that you have set. The next exposure will still have round stars but they will be offset slightly from the previous one. That's how dither works - it has nothing to do with the tracking rate.

Very impressive... amazing actually. I am really looking forward to hearing more about this. It is definitely something I could use.
I am among those who have cameras that require that I dither my frames. I haven't figured out yet how I could take advantage of this and still be able to dither frames.
