>>>Another AP900 user in Europe has been using the ASIAir for guiding without any problem...so it seems it can be done. maybe get in contact with that user and see what are the working settings? --

No, I'm using a USB to RS232 serial converter cable (Keyspan is the make) that is plugged into the AP900 controller serial port. (I also tried the simple RS232-USB cable that came with the

Well, then start without ASIAir. Just connect PHD2 directly to the mount. make sure you set up the ASCOM driver in PHD2. Make sure also that your mount and guide scope entries are correct and you have

The same one that is included with the ASIair? I don't think that will work for the Windows machine. I use a USB to serial converter and the serial cable is then connected to the controller box. --

Yes, found the Cal file - I've attached. The guide star is lost at the start of Cal, so Cal does not get completed. When using PHD2 for guiding, I have the mount connected directly to my PC via the

This indicates clearly that the guide pulses are being sent, except they are being sent backwards. So instead of correcting, they are adding to the error. Every guide pulse is then sending the mount

Also, I see that the mount control is through INDI. The INDI mount compatibility page indicates that the AP controllers aren't supported across the board so it would depend on which controller you

Steve, OK so I don't think that I am quite up to speed with you here. If you are testing your guide camera out with your Windows computer running PHD2, then how are those guiding commands getting to

thanks Dean and Bryan.. - guide camera (ASI290 on a WOGS61 guide scope) is connected via USB to the ASIAir (or to my laptop when trying PHD2 directly) - mount is also connected to the ASIAir USB port

Yes, how is the guide camera communicating with the mount? Are you plugged into the guide port or are you relying on the RS232 connection that the ASIAir is using to slew the mount? The ASIAir looks

Hi Terri, I still have a doubt about this case that I had detected, because with my mach1 GTOCP4 that I had before I always had the keypad plugged in and I think that (Like the PC) was enough for

Place the mount manually (clutches loose) to Park3 position. Cycle power. Then resume from Park3 and you should be ok. Slew to a known bright star and the scope should be pointing close. Use the

I wonder if there is conflict between tracking and PHD2 over COM ports. How do you have everything connected? Be specific...it's hard to diagnose without detailed info Guide camera to ASIAir...best

Set up my new-to-me Mach1 CP4 last night and thought I was off to the races, but I seem to be hitting some kind of "limit" that prevents me from slewing west. The mount is also reporting CW up when

I tried using PHD2 natively to guide the AP900 and I get the same result: the AP900 is tracking fine until I initiate PHD2 calibration or guiding. Within 2-3 seconds of initiating PHD2, the

Maybe this is possible already with APCC? For those of us without a permanent mounting or observatory, we setup and break down our mount (hoping a mach 2 before too long) each time out under dark

Hy Bryan, thanks for your response. I use platesolve2 as my base, but have a local copy of astrometry.net for blind solving as well. I have not tried Astrometry.net outside of using it with

Konstantin: That is good to know. Terri: I have use of a permanent pier at a roll-of-roof observatory 100 miles away at the club's dark sky site but I tear down the mount and bring everything home.

Thanks Dominique, have you gotten any feedback from A-P or Simulation Curriculum? I was wondering if it's normal, per past correspondence I've read about needing some initialization. I know Sky

Terri Which of the plate-solving options within SGP are you using? I know the APPC Pro manual suggests PlatSolve2 form Planewave, but ASTAP is much faster. A local install of astrometry.net is
