It's summer here in the Southern Hemisphere and I'm learning how the modeling works in my Mach2. Two nights ago the temperature at night was high, around 20ºC and in almost all the frames of that

Aloha Steven and Deonb, Yes, I have been using the Sharpcap polar align tool and really like it. And I understand what all is going on now with the az and alt (ie 2 star) drift alignment. I'm

Is there an atmospheric refraction calculation happening? If so, then the difference would be about +- 1/2 degree from one side to the other. Rolando

The RA axis actually visually move. Not by a lot, but much more than can be explained by sidereal. I don't rely on the camera for anything yet since I can't rationalize the mount movement yet. I've

Great looking setup and exquisite detail in the image. Rolando

The original keypad has only the meridian delay feature. You can move the meridian flip point either east or west so when you enter the object again and press GoTo, the mount will flip around and

This weekend, I updated to the latest APCC version. when using Maxim DL6.26, and an updated Win10. I live in denmark (EU), and have learned early on (around 2014ish, I think) that in order to make

If you have the original keypad software then yes, the meridian flip feature is accessed by pressing button 9. I was under the impression that you had the latest software, which places it under the

Does the RA axis actually move, or are you relying on where the camera is aiming to detect RA movement? If it is the latter and the camera is not orthogonal, then a 180-degree flip will not be exactly

Hi, I am happy to share my first picture with the mount. I hope it is not off topic, but please tell me. After years running an observatory I came back to a nomad set up and I have chosen the

Hi John, I just wanted to follow up with you on this issue. Did turning off pointing and tracking rate correction fix the issue? I am guessing the data for the pointing model you are using may have

That's great to hear! BTW, it would be nice to also post on CN that the issue has been resolved. -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command Center):

Hi Ray, It is easy to automate the flip point. You can do this using the AP V2 ASCOM driver (or the hand controller). You can configure the flip-point so that the mount will flip at the necessary

Hi Mark I measure the OD of the threads at 1.083" with a thread pitch of 14 tpi. This is definitely not an ANSI standard thread. Maybe Roland, Howard, or George can comment on the reason this size was

Steven, I’ve used Sharpcap in the past and have done so with the Mach2GTO as well but I’ve recently discovered that my Sharpcap and Polemaster alignment disagrees with each other by over 4

Hi Chris, I appreciate your feedback, but nope, I am not new to astrophysics mounts. There are many brand mounts out there that have a meridian flip feature. You hit one or two buttons and she flips.

There must be some communications failures going on here. I currently have seventeen mounts/scopes using nine different GOTO systems and AFAICT, not one of them has a "do a meridian flip" button or

Not sure whether or not I should post the resolution back here, but Roland was able to help me out, and it works great now without any oscillation.

Hi Roberto, I don't think that is what Rolando was referring to. That is a work around that tries to trick the mount into thinking it has hit the meridian. Your settings also may cause the mount to

Raymond Read the manual: https://www.astro-physics.info/tech_support/mounts/keypad/keypad-manual.pdf Page 59 has specific instructions for the Meridian Delay feature. Roberto
