Star Adventurer guiding - failing calibration?

Recommended Posts

Hi boys and girls

Setting up my SA under a RPi3+ in EKOS using PHD2 as the guider and running into difficulties in getting it calibrated.

I have set it to RA guide only in the Global options, and set DEC orthogonal to RA - which I believe is the correct thing. I have the mount set to On Camera and I did a polar alignment with my Polemaster.

I am using a ZWO120mini on a ZWO Guider - and I have set the correct f/l and pixel size in PHD, but when I run the calibration it fails on the Backlash Correction steps with an error saying it has not moved far enough. The E/W movements are fine and it reaches the 25 pixels no problem, just this last bit falls over!

Am I missing something obvious here, if not, any insights on what I'm doing wrong!

 

Thanks :)

@daz Does the SA drive in reverse direction to correct backlash or is it waiting for the sky to 'catch-up'?

I *think* it does Francis, but not 100% sure!

Which backlash is it referring to ? mine normally only does the clearing backlash thing in dec.

I assume it means RA Dave as I had RA Only set in the global options... but it's only an assumption at this point!
