One last point: Make sure the scope is pointed at least 30 degrees above the horizon in both orientations (pointing east, pointing west). That will take out any effects of refraction. Mark C

Thomas, *After* the merdian flip the DEC and RA behaviors were consistent, about 0.5 arc sec. That is what you'd expect - seeing limited performance. People pay thousands more than you did to get

I'm sorry to hear of these problems.? So your guiding problems started after the installation of new parts and the issue has been going on for months and so far nothing you have done since has

Hi Tom, You will need to connect a laptop to your mount to run PHD2. The guide logs then appear in the Documents folder, which is what is needed. The apps I mentioned will only work with PHD2 files

John, I have not used PHD2.? I've only used the asi air.? I don't know if the air produces a detailed log.

On backlash it makes no difference to how well the mount gets adjusted, the Losmandy mounts were designed with some slack in the system. It is just slack that needs to be taken up before anything

Hi Tom, How an ASI Air records the guiding data and how it could be used to diagnose RA errors is not something I am familiar with. However, if you can do some guiding with PHD2, that would provide

This is after the meridian flip.

Does this help?

Tom, i do see the jumps, but it's hard to see when or why they happen from a screen shot. Can you capture some autoguider logs (text) showing the position error, and corrections? Don't know if you can

Paul, I took a couple of screen shots of what is happening tonight.

Tom, how does the autoguider calibration look compared to before? Does it take RA and/or DEC more time to reverse direction? If dithering takes a lot longer now, I start suspecting increased backlash

Thanks Paul.? I had notifications off.? I apologize. Tom

John and Paul, Thank you for the replies.? Apparently I don't have notifications enabled so I just saw your messages. My balance is good and I do a new polar alignment and calibration every night

It has and you’ve already received a couple of suggestions: /g/Losmandy_users/message/83481

Hello, I was wondering if my recent question has been approved for the forum. Thanks, Tom

After making any mod like this you should do a new polar alignment, a new PEC curve (if you do that), and a new guiding steps calibration. Also make sure you are still balanced and redo carefully. The

Hi Tom, hard to tell what’s changed in your setup, but I’d at least check the balance in Dec and RA and make sure the additional hardware hasn’t affected the worm/gear mesh. Regards, -Paul

Hello, I bought an RA extension and 12" pier extension for my g11.? The goal was to improve meridian flips with my 130mm refractor. I checked all the screws in both components and they are
