The PHD2 manual states that their latest interface allows the imaging application software to specify the dither settling to a specific pixel accuracy for a specific continuous period. "If the app uses the latest PHD2 server interfaces, it can specify a settling requirement that might look like "guiding errors must be less than 1.5 pixels for a period of at least 10 seconds." I believe adding this type interface would be a nice improvement in BYE. I'm using BYE version 3.1 with PHD2 version 2.6.6.

Is it possible to dither when I am not auto-guiding? I want to use this during wide field imaging on my Losmandy StarLapse mount between subs. I don't use ASCOM. Thx Jim

I tried Ascom dithering during two night, but without much success. My idea was to use dithering without guiding for wide fields with a camera lens. My mount is an AZ EQ6, using the Ascom Celestron driver (not Eqmod!). I enabled Ascom dithering in BYE, which happily shows the ditthering between exposures. But the result is that the mount moves in somewhat constant steps of ~+30 ... +40s in RA. See below for an excerpt of the log file. The "Dither settled to ..." values don't seem to be correct, the new mount position as shown on the control display and in BYE is the one shown in the log as "Current ..." of the next dithering step. Same thing in 3.1.8 and 3.1.11 (.11 BTW is *way* slower in starting the program!). Any ideas?

I use dithering off and on and use the default values. Can somebody explain... - Dither Aggressiveness 1-5 value - Settle Dither At 0.10 to 1.00 What exactly do these two parameters do? Jim Phoenix, AZ

Hi. Any chance to dither without guiding software/guiding scope? It would be useful for a function such as that of APT (Auto dithering). Thank you. Giancarlo.

I'm trying to use the DSLR processing procedures presented by Tony Hallas to the SCAE and recorded for Youtube. To do this, dithering should move "two to three star diameters". I'm not sure how to accomplish this. Is this something that can be done in BYEOS or should I be doing it in PHD2? Al
