Hi Barry,
Good to hear from you again, but sorry to hear that 10 is giving you grief. I’m still with 7 and dread the day I have to go with 10. My suggestion is to send a log to Jared and Ken of both successful 7 and loser 10. Auto center has been working well for me with 7…I know that the UAC in 7 had to be turned off, but not having 10, I don’t have a clue as to what might be happening… CS and Happy Trails, Jerald
For some reason my GM1000HPS refuses to flip after the meridian has been passed. I haven’t investigated this further, as there is an easy workaround. Everything works correctly when I flip ten minutes prior to meridian – I don’t wait for meridian since my lights are usually <= 10 minutes.
As far as I understand it, the 10Micron firmware will only permit an auto meridian flip to happen before the meridian is passed, hence the suggestion to set the minutes passed meridian figure in SGP as -5 (minus five), that is to flip 5 minutes before the meridian is reached. To enable this in the handset you have to set the Flip Slew Tolerance and Flip Slew Guidance parameters accrodingly.

Hi all,
have updated 10 micron to the (beta) Version 2.14.4 as suggested above.
Mount still does not flip.
Could you tell a little more detail on the settings that are needed for the mount per your knowledge?
Our Settings are:
Flip slew tolerance: 5°
Flip guid tolerance: 6°
Should we disable the “wait for merdian” in SGP?
If anybody can help, would be great!
We are gong to bed now. frustrated again.
Something appears to be amiss with the driver (or settings in the driver). This log statement:
[07.09.2016 23:55:17] [DEBUG] [Pier Flip Thread] Meridian Flip: Telescope failed to perform meridian flip
means that the pier side before and after the flip were the same. Following this, it usually means the mount was issued a slew command and it decided it did not need to flip. Unless your mount can perform a meridian flip in 6 seconds, it looks like the mount did not attempt it…

We would need to see the mount logs to be sure. They would probably provide further insight… your mount reports it was indeed past the meridian, but did not feel inclined to flip.
Here’s some of what I posted on 10 u forum:
Seriously though Jari, I can’t thank you enough. Here are my present settings for the daytime run that worked three times and resulted in successful meridian flips:
SGP: set to -5 minutes in auto meridian flip
HC on 10u: flip slew tol = 3 degrees
flip guide tol = 5 degrees.
I also have wait for meridian checked. Most important of all is to display the LST on the hc and make sure that it is not locking up at 12 00 00. This would usually happen when I would do daytime testing. I would shoot one image b4 the meridian crossing and the flip would work but at night, after one or two images b4 the meridian, LST would lock up. Firmware 2.14.4 solved this problem…Gunny
Hi Gunny,
what is LST?
Local sidereal time. Under the display button on the hc. Set the hc on that and see if it is locking up…
Hi all,
thanks for your answers.
Tonight, the mount did perform her first pier flip. We are very happy!
For all haveng similar problems, these are our parameters:
Mount: 10Micron GM2000
Firmware: 2.14.4
Driver: 10Micron Mount
Flip slew tolerance: 0
Flip guide tolerance: 1
Software: Sequence Generator Pro
set to -5 min for pier flip and ,wait for flip’
thanks to all, hope it will work all nights now.
best Anna
Great.
Similar to the EQMOD guide we posted in the help manual, I would like to do the same for 10u mounts. If anyone has screenshots and advice for compatibility with SGPro, please post them here and I will try to cobble them together to add a section in the help manual.
Hi Ken,
Today we wanted to use same settings as yesterday, because they did work.
But today, we got an error telling us that we can not use -5min in SGP because the mount dies not support that. SGP told us using 0min.
Yesterday we could use -5 min pier flip worked good. We did not change anything.
Do you have an idea what happened?
Thanks,
Anna
Yes, SGPro does not support early meridian flips for mounts that do not support the ASCOM defined ability to set the side of the pier the mount should be on. In your case, your mount only supports flips via “slew” when you are pointing at or past the meridian. If you were able to set it to -5 before, it is likely because you did not have a telescope object selected or connected. In this case SGPro was not able to determine the type of mount you had (its properties) and let you enter whatever you want.
Is there a reason you want to flip 5 minutes before the meridian? Is 0 not sufficient?
Hi all,
Last night the mount again did not perform the pier flip.
We started everything with exactly same settings, but SGP gave an error message and did not allow the -5 min setting, telling us the mount would not support flipping prior meridian. We tried using the 0 min instead, but the mount did not flip.
It is really anoying.
Anybody has an idea what we could try?
Best,
Anna
When I had a 10u mount I recall there were two flipping parameters - giving you a window in which to flip. To early or late means that one side or the other will be outside the allowable area. My mate has a GM2000 and when I’m next round there I will check out a few things.
@Moosmann - which ascom driver are you using? I have been using Per Frejvall’s ascom driver and I have had a half-dozen or so auto-meridian flips and everything works well with the settings Gunny outlined:[quote=“Gunny01, post:10, topic:4098”]
SGP: set to -5 minutes in auto meridian flip
HC on 10u: flip slew tol = 3 degrees
flip guide tol = 5 degrees.
[/quote]
Also tick the box ‘Wait for Meridian’ option in SGP.
After my first auto-meridian flip with my GM1000HPS (I have only had the mount 3 months or so) I tried using the 10 Micron ascom driver and I too had an error message generated by SGP and a subsequent re-set of the Minutes to Meridian Flip from -5 to 0 by SGP. I never tried the flip and quickly reverted to Per’s driver.
Not sure if you have posted on the 10 Micron Forum but I know ChrisLX200 a UK imager has the GM2000HPS and automates his sessions with SGP - perhaps he will share his settings.

Hi all,
we used Pers driver tonight. We did set to -5 min in SGP, with Pers driver that is possible.
unfortunately THE MOUNT DID NOT PIER FLIP.
We do nit know what to do now.
Anybody any idea?
Best regards,
Anna
It’s still not clear to me why you need an early meridian flip… equipment collision issues possibly? What about 1 or 2 minutes past meridian instead of 5 minutes before?
Also, @Gunny01 is trying to post some screen shots of his setup so we can create a sort of guide around 10U mounts.
Hi Ken,
Equipment can go till about 7 below meridian.
But in one of the ealier posts, we learned that the mount will only pier flip prior to meridian. That seems unlogical, but it seems to be a true statement. That is why we use -5min.
Tonight the pier flip did work again. We are not sure why. Possibly because we declined in the SGP settings an external control. Or because we terminated the link to the planetarium program. We will try again to be sure it doesn’t again work just once. We could not really good read gunnys screenshots as the resolution was low.
Best regards,
Anna
I tried yesterday to post the screen shots, but they did not go thru. Here’s another try. Also, you do not want to have external control enabled in SGP from what I’ve seen. That is designed for ipads, ect and it did screw up my results when I had it checked.
Well, I see the image resolution is poor, but you should get the idea. If someone has a better way to improve the resolution, let me know. These sized images have always worked well on other forums.
LST is NOT something that you have to wait until midnight for. It was the time that locked on my hc when pier flip did not work. This was due to a problem with the firmware.
Daytime testing for the pier flip can be done. Just make sure you turn off focusing, plate solving, auto center, ect. I’ll try to find a link to the daytime testing procedure and place it on this forum.
You’ll have to take several images b4 the meridian flip with the camera shutter closed and I would recommend using the Ha filter and cover the scope aperture to prevent sun damage. I used 4- 10 min. exposures b4 the flip and observed the lst on the hc. Hc should show the lst and SGP should show a count down to the pier flip. If it shows time to meridian flip only, you’ve got a problem. When this happened to me you could clearly see that the lst had locked and the flip did not occurred.
The -5 min setting to meridian flip was recommended to me by a fellow on the 10 u forum and CN. I’ve seen times set from -5 to -15 minutes. I have no idea why this works, but obviously it does.
Caveat!!.. This is what has worked for my equipment. Use at your own peril, and read the manuals before you attempt this and understand the procedures. This is not the time to take short cuts ( I learned the hard way ). Until you’re comfortable with this procedure I would recommend being by the “Kill Switch.”
Hi Gunny and all,
Thank you so much for your help.
I think we know now what went wrong. Somehow, the ascom driver switched by itselfe from Pers driver to the 10Micron Mount driver. Doing so, the -5min were automatically changed to 0 and pier flip did not work.
We deinstalled the 10Micron mount driver and tonight pier flip did work. We are very happy!
unfortunately, the plate solver moved the object to the wrong position. We did try that as a dry run (as we always do) and it worker about 3 times in a row very well. But, as usual, not at the real test. At the moment, we are unsure why that did not work after the Flip.
Maybe someone has that problem too? (We use astronomy.net local server)
Best regards,
Anna
