Message William, Just go back about three weeks in the posts here and you'll find probably twenty messages regarding the two greases AP recommends. Woody

Message Ya know, I think this thread has just about worn out and snapped. If you haven’t learned what you want or need to know about these things by now, you probably never will. One poster has been u

Message Joe, 1) In my system I measure (and set) nominal 12v voltage at the END of the line -- at the RIGrunner and then double-check at the device, both of which are mounted on the scope. So this aut

Message Joe, I don't know how it accomplishes voltage regulation, but when I vary the input voltage to my 150 watt DROK -- output voltage remains rock steady where I set it -- to within 1/100th of a v

Peter, I see that you’re using a QSI camera. At the bottom of page 11 in the QSI 500/600 operator’s manual is this NOTE. I underlined the key sentence regarding what happens when you increase camera v

Message Don, You're correct. I just went back and looked at my message from Jeff and he indeed did say 13.8v would just generate some additional heat, but the higher voltage should be OK. He wasn't th

Message Gregory, I think three of your messages have successfully posted here in the past few minutes as well as on another Yahoo Group. It's working! Woody

Message Gary, Don't take my word for it, take a look at QSI's paper on camera input voltage. It's available on their website. Yes, they've put in voltage regulation circuits so their current line of c

Message Christopher, I assume this is addressed to me, and that the tests are to the 150 watt DROK I have. And once again, I'm not an electrician or engineer, so please bear with me and understand I m

Message Actually I believe Roland was referring to the Powerwerx variable output PS which AP also sells. That's the one the thread was discussing. I've had two Pyramid power supplies. The latest one t

Message Joe, When I touched positive voltage to the EN terminal, that apparently flipped an internal switch that then enabled the higher power output. And once I did that, the switch has been thrown a

Message Joe, I too wish there was documentation other than their crudely worded (or translated) Q/A posts. But the I/O terminals are clearly labeled on the actual device. The only thing I wasn't clear

I think I did my watts to amps calculation incorrectly. This Drok DC to DC Buck/Boost converter is rated at 150 watts. 150 watts at 12v = 12.5 amps. That “should” be plenty of power for your cameras a

Yes, this looks like the same one I bought through Amazon. Woody https://www.ebay.com/itm/DROK-DC-DC-6-32V-to-0-8-28V-150W-15A-Adjustable-Boost-Buck-Voltage-Regulator/152764675691?_trkparms=aid%3D5550

Message Here’s a link to the 150 watt Drok Boost/Buck I purchased through Amazon. https://www.amazon.com/gp/product/B00C9UAE28/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Woody Do you have a link to t

Message Joe, Roland's recommendations are for his AP mounts. "Most" other astro equipment really wants to see something closer to 12.0v - 12.4v -- particularly cooled astro cameras. Even if they say t

With all the discussions regarding power and power supplies in observatories, I'm continuing to refine the power system in my mobile observatory. My latest plan is to go back to the manufacturer's sup

Message CG As I recall, my RAPAS came with initial alignment instructions inside the box. It think it's just a single sheet of paper. If you can't find it, I'm sure it's available from AP's website. O

Message I've found that aligning my Mach1 using the RAPAS is plenty good enough for imaging -- even unguided. HOWEVER -- the RAPAS needs to be aligned to your mount the first time. After initial align

Message Dave, So your EN terminal is always connected then? If mine somehow shuts off, I'll try that. Otherwise, I "think" it's working fine now. I cycled power several times and each time, the light
