My less than a year old G11T in my observatory (climate controlled) has been idle for a few weeks. Its just been too cold for me. So the other night I was ready for some imaging. Everything started

Paul, I moved the CW after the flip to keep the east bias.? I did not do that last night, I did it the night before.? I have the log but the guiding was just as bad.? What do you think I should

Thanks, Tom. You can use PHD log viewer to review the results of this log. When you say you adjusted it, what did you do? The weight needs to be re-adjusted after flipping to the other side of the

Thanks for all the advice.? I really appreciate it.? The asiair does provide a PHD2 guide log.? I am completely unfamiliar with it.? It is a text file with a lot of text.? I will attach it.?

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
