Yes. I have many decades experience designing, building, and using electronics, and I am familiar with DMMs. I just wanted to confirm that the Mean Well supply still works correctly if the negative

You can use a DVM or digital volt meter to check any power supply as long as the power supply voltage does not exceed the meter rating. Make sure the DVM leads are attached to the DVM properly, ie

Joe, please call us at Astro-Physics. 815-282-1513 Just ask for me.

Yes. I bought this 15V 7A supply for $20 on eBay:

Can you link to this power supply, are you referring to their little switcher power supplies in the perforated metal cases?

Yes, the negative terminal is always the ground terminal which is also connected to the case. Roland

Make sure that your hand controller is set to EXT so that it does not send time, date and location to the mount when power is applied. EXT allows the mount to be properly initialized by the ASCOM

A week or two ago, Roland stated that the Mean Well works fine with A-P mounts. I bought a 15V model, and have a question. The AC line input ground terminal is connected to the metal case, as it

There's no part two video but it's not necessary anyway. Part 1 video is more than enough. Peter

Okay, great. Yes, parking to Park 4 will work okay. -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apcc Author

If you plate solved the coordinates that would result in an absolute RA/Dec sky position. If you were off by one hour then you could plate solve and sync (probably all-sky). Rememeber to temporarily

Using APCC Go To After plate solving I moved the mount via APCC back an hour and found the Crab and centered it by imaging, then incremental movements. All mount control is done via APCC pro. At this

Yes. Hint: There is very good information in the help file. Clicking the "?" button in many of the control group boxes in APCC will bring you to the relevant section of the help file. -Ray

I have my hand controller plugged in but it is ALWAYS initialize from APCC. No changes were made SITE information. I am using APCC pro 1.7.1.1 Right now I am imaging the Crab Nebula at RA
