Wayne, yes you can and should leave tracking rate correction on. You might be able to track ISS but the computer time has to be perfect and ISS not have changed course after you acquire coordinates

Ray would I still leave tracking correction on while using Horizons? Just tried Horizons for tracking the BepiColumbo mission. Got it to work but would have to cut down a number of trees and

Yes, would have to as it would override the lunar/solar setting. A better option is to use Horizons (the application included with APCC) to get the dual axis motions of the moon or sun. Then tracking

Wayne, Have you tried turning down aggressiveness? You may be chasing the seeing. Also, have you tried back to back switching between model on versus model off? It could be seeing was worse at that

Hi Max, Have you tried configuring Passive mode in APPM's Dome Settings? -Ray Gralak Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of PEMPro V3:

I was trying to using POTH with APPM It is not longer aligning with the dome. Worked fine with APPM in 2 months ago It looks to me like the dome thinks it is on the wrong pier side. The scope driver

Yes, that works. Roland

What I'm doing now is hand-tightening all clutches as hard as I can, but I will make sure I keep them consistent

That's a question for ray Gralack, but I would assume that you would set the tracking rate to lunar or solar and the model would automatically not apply corrections. Roland

Also another thing - on the Mach2 make sure that all 4 clutch knobs are equally tightened, especially in Dec. If you have only one or two snugged you may get slightly longer reversal delay in some

PS another model related question - do you turn it off when doing lunar or solar imaging?

I will check that delay setting, although I'm sure I didn't have a delay set in MaximDL. Yes definitely spiky! Roland, I'll give it another try tonight and check in with you tomorrow, I don't want

I just made that entry. Anxious to see the difference in guiding when the skies clear. Thank you so very much!!! Phillip

Under "Camera Settings": Time Lapse (ms). Set it to 3000 for a 3 second delay between exposures. Rolando

Absolutely, with an encoder mount you will want to have a delay between guide pulses. The reason is that it takes a moment for the axis to fully respond and reverse in Dec when a command comes in. In

Hi Craig, Yes I do see the spiking as you described. Could you please tell me where to find the setting to have a delay? I did not see it when looking under the Brain in PhD2. Thank you, Phillip

I came up with a removable handle to safely carry and mount the 92mm Stowaway refractor. https://www.youtube.com/watch?v=wyZPFgAQ0iQ tony

Phillip, Is your auto-guiding graphc really “spiky”, flipping back and forth over the centerline? If it is, then you might try introducing a short delay after each auto-guiding correction. I

Hi Wayne, Recently, I upgraded to APCCPro and used the pointing model as well. While tthe PhD2 guiding graph did improve t(flatten) he RMS value remains around 1" like your experience. I would be
