MinMo in PHD2 is set in pixels (or fraction of a pixel), so will vary depending on your guiding image scale. And RMS in PHD2 is reported in both arc-seconds and pixels, though sometimes people seem to

Guiding was definitely a lot better than before. This is using the 115mm, right? To understand whether your guiding is seeing limited or not, and to help determine what MinMo settings to use, you shou

Just one comment on your GA run: You only collected 19 samples - that's not a lot. You can either reduce the sampling period (say, 2s) or increase the time you let it run. Basically if you want to use

@Nicolas, to clarify: The GA run shown here was done through the main scope, not the guide scope? So the guide scope connection is not the cause of these DEC jumps...? Of course, guide camera connecti

>in case you are wondering the GA was from the main imaging scope but now guiding is being performed w the small guide scope For these tests it really is best to keep everything the same (i.e. don't s

When you do Shift + Guide you will see PHD2 enter calibration mode and perform a calibration. There really is no confusion on whether it is doing a calibration or not. Try it and confirm for yourself!

>Yeah that sounds like the method to use and likely would have worked last time had I calibrated correctly rather than using the calibration restore function. Correct. So were you able to gather data

>yes I was considering the 115 my only concern is I wanted to see how the mount operates with a little more stress of the larger refractor. What do you think? Ultimately you will want to grab logs for

No. Please just do the following: - Make sure PEC is disabled on your mount - Point somewhere at the intersection of the meridian and celestial equator - Nudge the mount North until the guide star mov

Both of the logs you posted on the CN thread showed actual GA runs (it shows the GA findings in the logs at the end of the run). Did you also disable guiding in the brain? Did you reenable it later? A

This obviously doesn't disable guiding, and if there is a spike movement greater than 20 pixels, or the guide star drifts more than 20 pixels during the test then PHD2 will still issue a guide correct

Yep, it looks like the guide cam was rotated since the previous calibration run and prior to running the second GA session you posted the screencap of.

Brian, unfortunately that run was also likely bad (using bad calibration data from a previous calibration run)

Hey Nick, The Mach1 does break down into two smaller parts. If you are finding the weight to be too much you might consider splitting it and mounting the RA base on the tripod first and then adding th

Thanks Konstantin - will give that a try!

Hi. It looks like I need to reload the image in my Mach-1 keypad - I'm getting the "Object Below Horizon" error message, but only for non-stellar / non-solar system objects. I did a search but could o

Well I'll be the contrarian :) No one knows these mounts better than Roland. Empowering him with tools like PHD2 log viewer so he can see the issues people are reporting seems like it can only help th

Hey Ray, Roland asked for screenshots, which imho, is an inefficient way to share data. As a lot of people post their actual PHD2 logs whenever they are having problems, having access to the PHD2 log

Here's the same screen grab as an attachment (rather than an image) Roland - might be time to download the PHD2 log viewer - simple to use and will let you see all of the guiding data: https://openphd

Here's a section of the graph showing some of the large excursions in RA and DEC.
