Is it possible to use integer multiples of sidereal rate for slewing the mount? I have an application where I would like to slew between 10x and 18x sidereal rate. But I think the only possibilities are 8x and 20x with the current ASCOM driver.
ZWO ASCOM driver supports any rate in range of 0.25 to 1440 sidereal (approx. 0.001 to 6 deg/s). Try MoveAxis(axis, rate) command. See ASCOM Platform 6 -> Help and Device Interface Standards, search index for Move Axis method. Note that "rate" parameter is in deg/s so You must convert sidereal to angular, ie 10x sidereal is 0.0417805556 deg/s.
Ceat Yes, we support 0.5, 1, 2, 4, 8, 20, 60, 720, and 1440 rate of sidereal speed in ASCOM and AIR.
With the recent firmware updates, I heard it might be easier to chose other slew rates than the default 8x and 20x. Does anyone know if this is true? What's the best way to, for example, move the mount at 15x or 18x ?
ASIMount@ZWO it would be awesome if the drive supports variable rate for both RA and Dec axis. This would enable true satellite tracking that I had been asking for a while.
kaiyung For now, RA and DEC should be the same rate. But your suggestion is very useful, we'll think over the requirement. Thank you for your support.
I would also like to have some additional slewing rates between 8x and 20x sidereal rate, for a spectrophotography application which requires slewing across the target of interest (usually the Sun).
