ASIAir PRo problems around Zenith/meridian?

Scruffy_the-janitor

Hello all,
I have an ASIAir Pro connected to an ASI1600MM with filter wheel, a Radian Raptor 61 and EQ6-R Pro. I am able to polar align fine and it finds objects perfectly, until I try for M101 (pinwheel). The galaxy is fairly close to the meridian at the time and up high in the sky. The only way the ASIAir will slew to it will make the camera knock into the tripod. I cannot get the mount to slew the OTHER direction so that it does not hit it the tripod. I know a meridian flip is only possible in auto run mode but I cannot even get to the target to run the mode. Any help to convince the ASIAir to change the slew direction around the meridian?

Here is a picture of the set up, at the time of the photo M101 was at 22hr20min or so in HA. I stopped the slew right before it hit the tripod so its not even pointing at the galaxy yet. Notice on the ground I had to even remove an AZ knob from the point to tri and get a little more clearance.

The pier side and whether to perform a meridian flip or not are determined by the mount and not by ASIAir. The only thing ASIAir does is issue a GOTO command and it is up to the mount to decide whether a flip is necessary or not.
This may indicate a date/time or location issue. Are you sure that you entered those correctly? Do you occasionally use the mount with the hand controller (you seem to be using an EQMod cable in the picture)? If yes, connect the hand controller and do a factory reset and see if that helps.

While it’s technically accurate that the AAP only issues a new goto and it’s up to the mount to choose how to handle that command (flip or not). The issue is he has an EQ6-R Pro which works best when the mount is set to “FORCE FLIPPING”, this setting is a one-time setting each night, and therefore the AAP should be setting the mount correctly before issuing the new goto command.

So to sum it up - it’s the AAP fault flips fail by not correctly configuring the mount, thus causing failed meridian flips.

This is same for Celestron mounts, where it should be set to “Meridian - Favor West”, the default is to NOT flip, so when a goto is issued the mount doesn’t move because it thinks “I can still see it, I’m staying right here”

the AAP is responsible for configuring the mount to support proper flipping, today it doesn’t do that

When goto, Mount's posture is determined by Mount himself. Try to check the lower zero position, time and place, etc.
