I (not so recently) acquired an ASA DDM60 Std and Berlebach Planet tripod setup back in Nov and only now have made an attempt to set it up properly. Despite having owned Vixen mounts (GP-DX, SXP, and AXD), the ASA is simply just a different beast which, for now, to me has a huge learning curve.
I've got the most fundamental basic problems (even with the Berlebach where the clamps don't lock down the leg adjustment but just "slides" back to the shortest position), to iPad with RD Client RDPing into my NUC and the Move-Controls virtual keypad doesn't work but other buttons in the Auto-Slew buttons are fine.
So for the Berlebach, that's fine as I'll just leave it as shortest and find other ways to adjust bubble level. And for the iPad RDP can't control the virtual keypad, I can workaround with a laptop RDP which does work (go figure).
Using the ASA AutoSlew manual, I'm good with the Servo Setup and Balance. But the next part I'm stuck with which I need help with are :-
1) GPS dongle - Device Manager doesn't complain, but doesn't seem to pick up any satellites. So can I can ignore the GPS dongle but just :-
a) input my latitude/longitude manually. What about the elevation? Is it in metric of imperial?
b) my NUC is connected to my home WiFi so I can time sync with the my ISP's NTP server. Is that good enough? I don't see a date/time in Autoslew and assume if my PC's date/time/TZ is correct, that's good enough?
2) Homefind - I set my scope to point to zenith and my CW bar pointing to West. It seems to set it correctly (at least the DEC, the reading on the RA OTOH looks off), but I save that Park1 position anyway (but I don't Set new Homeposition as I've not done any PA, nor actual star position sync - which is the next problem #).
3) I use the virtual keypad to roughly point to a star, then I go to CdC select that same star in the planetarium. I then go ahead and sync in CdC.
However after that whenever I use the virtual keypad to move the mount (especially in the N/S) it seems to be in reverse! The E/W movements on the other hand seem correct.
For some reason the alignment seems to think I"m in the Northern Hemisphere with the DEC values increasing instead of decreasing when I try to point the scope to SCP.
The RA is sidereally tracking the correct direction for the Southern Hemisphere however.
'cos I can't even get the mount movements to the correct rotation orientation, I've not even tried PA-ing.
Anyone with ASA DDM experience is able to provide some guidance?
