The controller follows networking standards, which means the address can be assigned either via a static address (human set), a DHCP (IP address) server (home routers sometime do that), or via Windows stupid idiotic inane random address generator.  It all depends on details of your setup, and what you did the first time you used it.

 

So yes, it can change.

 

There’s a rather lengthy discussion on the subject in the “Astro-Physics GTO Servo Drive System Model GTOCP4 Operating Instructions” manual starting on page 12 and page 56 (at least in my version).  My recommendation is use ethernet (not wifi) and the first time you use it enter a static IP address and it will stop changing.

PEMPro comes with a comprehensive help file. Have you seen the section for the steps for PEMProV3 supplied with an Astro-Physics mount? Here is an online link to the same section:

Small galaxy Arp 28 in Pegasus

Took a quick snapshot of Arp28 in Pegasus with the 12" Mak-Cass when the clouds cleared:

https://www.astrobin.com/full/ufbzia/0/

The skies were super murky and still being affected by smoke from the western wild fires. Hope that the skies this winter will clear up and get back to their rich deep blue. Normally we have great transparency but this years it was not to be.

Re: Rookie Question

If useful to the below, here are some photos after the AP1100 did a hard night’s work.

 

Top view showing screw placement and saddle placement on the DEC plate.  The two bottom screws old the PPBAdv (and notice they are not quite straight across so there is a slight twist, not terribly noticeable, but not worth me drilling new holes although there is plenty of room to do so.

 

 

One of these screws needs to be short to avoid the bracket screws, also no room for a normal castle nut (I said earlier it was avoid a cable, sorry, bad memory, it was the bracket itself).

 

 

Here’s the real issue to be aware of: there is plenty of room to clear the motor housing on rotation, and by “plenty” I mean “not much at all”.  The bracket is holding the PPBAdv off the saddle maybe 1/8” or so (and is stiff enough it stays there despite only one bracket).  But you cannot do anything that increases that spacing much or it’s going to hit on RA rotation, same with any bracket that goes over top of the PPBAdv (or under-top in this orientation).

 

But despite being a bit of a hack, this works exceptionally well, all the wiring I need for the back of the OTA – camera, FW, focuser, guide, etc. is right there at the back, cables can be really short.  Only wire running to the OTA front is the dew heater.   And while there’s room for a dozen cables thru-mount, this keeps it down to only two, 12V and USB3.

 

The covered holes is because this is a PPBAdv first generation, and that top right USB (in this orientation) will not work with USB3 ZWO devices, or any USB2 device, so … basically nothing. The other is a variable 12V hole that exactly aligns with the 12V input power supply on the other side – I got inverted and plugged in the wrong one and smoke came out once.  Don’t do that.  (Pegasus repaired it quickly and relatively inexpensively though).  So the tape is to prevent a sleep deprived human working in the dark from doing it again.

  • How did you attach the powerbox?  I was thinking 1 screw and velcro?

It’s the pocket powerbox, I’m not sure if the larger ones would fit as the RA axis rotates.

 

I used two 1/4x20 screws, and one of the two brackets it came with (or maybe it was extra I do not know, but from Pegasus).  The bracket does not quite fit a 1/4x20 screw, so I reamed it out (it only takes a very little bit and plenty of metal).

 

I found two 1/4x20 holes, one was for a socket head, one for the countersunk angled head, and these happen to line up (I think there’s only two that do on one end only of the 16” saddle).  It is not quite straight but pretty close.  You have to slide the saddle back a step also.

 

With nuts on the bottom tight it holds the PPBadv straight enough I did not need anything else; I had planned thick double sided tape near the end, but didn’t use it.  If I recall you need a specific length for one bolt or it sticks up and blocks the temp probe connector.

 

It’s outside working for a living right now (and not doing well, it’s attracting clouds!) or I’d send a photo, but can tomorrow if that doesn’t make sense.

Re: PEMPro connection

This appears to be an Astro-Physics PEMPro V3 license, so to activate it on your computer you need to connect PEMPro to an Astro-Physics mount with a GTOCP4 or GTOCP3 with a V or later chip.

To me that tornado looks like an interplanetary wormhole structure from an advanced extraterrestrial species... ;)

Seriously, I always find these very pleasing to see that zoomed-in. They are interesting objects as well. Supposedly created by newborn stars accelerated ionised gas going through dense nebulas.

Sixteen years ago, using a C9.25 SCT @ f/5.6 and an ST-8 camera, I
imaged that same area in Ha, and came away with a much different
impression -- the larger region looks like an erupting volcano. So much
so, that I colored the image in Photoshop, and named it "Hydrogen
Volcano." Here's that image: <http://astronomy.mdodd.com/nebulae-05.html>

BTW, the pelican Nebula is indeed known as IC5070, but I believe the
small region we both captured is IC5067.

Smooth and sharp in all the right places!  It really does look like a hammer.  
What I wouldn't give to wander the halls of Astro-Physics and see the treasures therein.  :)  Or better yet, get a chance to use them.  What fun it must be to pull out a scope and think, "I wonder what this scope is like" and actually be able to play with it.

Testing out an older 12" F12.5 Mak-Cass which we built about 15 years ago but never put to use or sold. The mirror and corrector lens optics were made by Intes Micro when they were still operating. They are zero-expansion Sital. The rest of the mechanical parts were fabricated here. The tube is carbon fiber.

To take the image I added a CCD67 telecompressor in order to get a larger field. I took it in one night with just over 2 hours of H-a narrowband. It really needs longer exposure.
