Hi Bill, If you have a CP3 it's best that you stay with 1.8.0.9 until the next release. In 1.8.1.x a change was made to make the sign of the tracking rates consistent with what external programs

I have been using APCC Pro 1.8.0.9 with V2 5.30.10 on a AP1600-CP3 mount. I have a pointing model and have been running with Enable Pointing Correction and Enable Tracking Correction. When I updated

Yes Roland, understand. I did go out and measure the length of my own setup and estimated a 180mm at focus. I don't think it's fair to include the dew shield in a length calculation of weight unless

I totally agree with Bill Long and Roland. For many years I used the AP 180 F/7 EDF on my 1200 mount. By the time I added all of the accessories for imaging, including guidescope, I found the 1200

You can tighten that nut without causing any problems. The bearings will take up to 15 inch-lb of torque. Heavy vibration during shipping might loosen the nut. Put a dab of RTV at the periphery of the

Hi guys, I did what Rolando posted in the instructions below. I could actually turn the nut by 1/4 turn! I didn't have a spanner wrench and so I made a fixture to fit into the two holes. I first

Roland, I am the OP (I am assuming it stands for Original Poster). This is very encouraging as I am very much interested in the portability of the Mach2 GTO and want an option to be able to image it

I am guiding and doing unguided imaging with an AP160 scope (27lb tube) which has 1200mm focal length. The scope is quite robust with a heavy 4" focuser. Overall system length with extended dewcap and

An FLI 16803 camera, CFW5-7 loaded with filters, MMOAG, along with all of the other dressing for automated imaging is going to be big, bulky, heavy and really long. Now add the 180mm refractor, and

If you have very low dec backlash and/or absolute encoders, lowpass2 is the preferred algorithm Brian

Unless I'm reading it wrong, the OP is suggesting 50" and 52 pounds. The A-P literature says the Mach2 is fine for 60 pounds at 50" of length, and assume the A-P literature isn't defining a point of

Pretty cool that GA now does that as well. I should probably run that sometime... 😉

I should have clarified also that my 1100 does not have AE. Also, it did guide better after I clicked for it to change to Lowpass2! Thanks, Charles Sent from mobile device.

That is what I use as well. If you use the PHD2 New Profile Wizard, they added a checkbox for high precision encoders. If you check that, it will change to Lowpass2.

Charles, the same thing happened with my Mach1GTO CP4 a couple of weeks ago. The GA recommended Lowpass 2, so I gave it a shot. It hadn't done that before, but it gave me the best guiding I've ever

I have used Lowpass2 and it works quite well. Rolando

Also, if you run the guiding assistant for a while (10 minutes+) it will recommended a different algorithm if it thinks a different one might be more appropriate than the current selection. Last week

Try them, see which one works best for you. I have not had skies good enough for much imaging, and when it is clear I am usually testing other functions (modeling, unguided imaging etc). If it's clear

Excellent, it sounds simple enough. I use PHD2 now so the guide scope is set up. I was also wondering about Mount Guide Algorithms for both RA and declination. Last summer you were comparing

By the way that's set in milliseconds, so should read 2000 to 3000msec in the setup window. Rolando
