I have a question about slew rate in TPPA. I have a Losmandy G11T using the updated Gemini 2 driver. When using TPPA the scope slews to the first position at what ?think is a normal rate. However when slewing to the second and third position the slew rate is so slow it often takes 10 minutes to move to the next position. Anyone know if there is a TPPA or Gemini setting I should change.

Thanks, Frank

I believe the TPPA defaults to 3 degrees per second. That triggers the Centering Rate with the Gemini Slew. Change the "Telescope Move Rate" to 4 degrees per second and that should fix it.

?

Let us know if it works.

The reason is that the gemini does not have intermediate rates. You have Guide (generally 0.5x sidereal), center (maybe 20x sidereal) and slew (800x) sidereal.?

Slew is 3.342 degrees per second... if NINA tells it to slew 3 degrees per second... it tries the next slower speed... which is centering... if you ask it to do 4 degrees per second, it will go as fast as it "can" according to your settings... which will be slew speed.

Thanks Ryan, I'll give that a try.

I changed it to 5 and it worked perfectly. Thanks again Ryan!

Great to hear! Glad it worked. Enjoy your celestial alignment. :)
