I have a good problem. I have an ES EXOS2 mount loaded with a Orion 8" newtonian astrograph about a 25lb load. Running a wizard profile in PHD2 I can get between 1.0 amd 3.0+ rms. Anoter profile I have gets around .2 to .3 rms.
The first profile has the followin text in the guide log:
Guiding Begins at 2024-07-08 22:29:32
Equipment Profile = Orion Wizard
Dither = both axes, Dither scale = 1.000, Image noise reduction = none, Guide-frame time lapse = 0, Server enabled
Pixel scale = 6.45 arc-sec/px, Binning = 1, Focal length = 120 mm (this is correct from the wizard)
This is the second text:
Guiding Begins at 2024-07-09 00:40:14
Equipment Profile = Orion
Dither = both axes, Dither scale = 1.000, Image noise reduction = none, Guide-frame time lapse = 0, Server enabled
Pixel scale = unspecified, Binning = 1, Focal length = unspecified (This cant be duplicated with the wizard)
The 4th line of each differs, I created the second profile with the wizard but something must have gone wrong because the wizard won't let you continue without the guide scope info.
Lines 1-30 in the attached logs are with the first profile
Lines 31-37 are the second profile
This is a good problem because I have never had this awsome guideing before
The bad is I am afraid I might somehow damage or loose the second profile.

Can anyone figure what is going on here.
Thanks

Well, the problem with this wonderful guiding is that you are basically smoking hemp. :-) Without knowing the focal length of your guiding arrangement, PHD2 is effectively reporting results in units of pixels. Assuming the first profile is correct, your guiding is 6.45x worse than you are thinking. If you built the bad profile using the new-profile-wizard, you probably inadvertently fat-fingered the focal length field in Advanced Settings and set it to zero. So build another profile and move on from there...
Good luck,
Bruce

Thanks for the response Bruce. The "Bad Profile Orion.phd" without focal length is producing great images, pass the pipe :-). Using the "good" profile not even close, all over the place.
