The DC connector on the CP5 is a round 2 pin Hirose connector. You received a power supply cord with Hirose connector on one end and power poles on the other. The 24 volt AC-DC supply that came with

Thanks for everyone's suggestions, but humbly I have no idea what a Hirose connector is, and can't find them. The connector on my 24V supply that came with the Mach2 seems to be a standard red/black

Best not to cut the 12 or 24 volt cords because DC at that power level loses voltage for every meter of length added. Best to use an extension cord on the AC side where you can go 100 meters without

My concern is if people cut their power cords to extend them over greater distances to just make sure they don't set themselves up for future problems. -Christopher Erickson Observatory

The Mach2 power supply does not use Anderson power poles. It uses Hirose connectors. This 24 volt supply should never be used to power anything else, no matter how tempting. It is ONLY to be used to

Woops, replied to wrong post. Rolando

I have seen it before where bad PEC data causes all kinds of guiding grief. The manual PEC training function in the hand controller, combined with a transient user was the culprit. -Christopher

And MAKE SURE that you use a different style of connectors for the 24V power supply and 12V supply. You don't want to connect 24V to your precious camera or other 12V devices. Anderson makes powerpole

One of my observatory partners has an AP155 EDFS with the 2.7" focuser and are going to put it on the Mach2 and try some unguided imaging with it with my small pixel ASI1600MM CMOS camera. His

If the encoders are turned off, then yes, you will have PE. Drift is not something the encoders can fix. We have a utility that allows you to turn the encoders on or off. Also you can do it in APCC.

Hello Roland, Thanks a lot. That is interesting. So I guess this is PE with drift. I do have encoders on the mount though. Is it possible that encoders are not working? Regards Hemant

By the way, the majority of the tracking error in your images is drift due to polar misalignment and the fact that you are not using a model. For such a large scope and long focal length you really

Classic periodic error. Every mount has that to some extent (except for encoder mounts), is well known by imagers. Can be mostly eliminated with periodic error correction using a program like PEMPro -

Hello all, I am using a Meade 16 inch f/8 (FL - 3250 mm) on AP1600 GTO with AE. I am seeing some weird tracking artifacts in my images. I cannot go beyond a minute or so unguided. A couple of nights

Call AP and they will tell you, depending on which keypad you have. Rolando

Thank you Konstantin, I will definitely incorporate your suggestions. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin -

Yes, the pier is permanently mounted with the Mach1/Mach2 mounting plate screwed on to the permanent pier. However, I can't just drop the mount on the mounting plate and get the same position. I

Cost? (Asked in the subject line.) --- Mike

The batteries can be purchased from us, and they have the connector attached, so all you do is unplug the old battery and plug in the new one. Rolando
