Bear in mind it was a tape measure stuck through and hooked over the top of the azimuth adjustment.  I'd far more trust someone with a caliper.

But the main message I had was, if it's about clearance or something, it's not round -- the CP4 side has all sorts of stuff sticking out above and (with the CP4 bracket and CP4 mounted) below.


APPM and ASTAP

Hi,
I just installed APCC.  I was planning to use ASTAP for plate solving, but it does not appear in the dropdown menu in APPM.  I have ASTAP installed and working on my computer.  I checked and confirmed that I have the latest version of APCC, ASCOM, and ASTAP.  The Help file shows that ASTAP should show in the dropdown menu, but it doesn't appear in mine. What am I doing wrong?

Thanks!

Hi Greg

I measured about 9.60 inches diameter with a certainty of + 0.005 inches on my 1100 mount using a spring caliper. If you need closer than that (to the nearest 0.001") I can make that measurement with my vernier calipers the next time I take my mount down. Probably in another week or so.

Linwood's measurement of about 9 inches makes me wonder if Astro-Physics has changed this dimension.

Ignore this note if you need precision.    It's about 9" or 9.125" as best I can tell.  I don't want to take it apart, and this is a tape measure suspended about an inch or so above the base to pass over the azimuth control in front, so the angle is misleading I think on the dimension, I think it is a bit over not under 9".

Real rough measurement, my caliper will not go nearly that large. 



Assuming that's the dimension you mean.

Bear in mind on the other side there's a flat surface, so the azimuth controls (below showing only the left one) extend well over, but immediately above the ring.   There's also the mount for the CP4, that here I have extended out 1/4" or so for clearance and cables.    By default it is flat against the flat area on the ring.

Hi Tom,

It would be nice to just slew to a certain alt az coordinate to do the recalibrate at the start of a session.
APCC's Goto/Recal tab has a slew to Alt/Az position, which can be saved and later recalled. Also, the AP V2 ASCOM driver can do a similar action.

Is that what you need?

Re: Pegasus Pocket Power box not available to APCC

ap@CaptivePhotons.com
 

I'm on APCC 1.9.2.3 and Pegasus Astro Observing Conditions Driver 1.5 9 (kind of old maybe a newer one is out there) and Pegasus switchbox 2.3 software and I can see it, and it tests.  I tried it both through the hub and direct. 

Are you sure you installed the ASCOM driver not (just) the powerbox software?   On the Pocket version (and I think others) it is two different installs.

Pegasus Pocket Power box not available to APCC

Joseph Beyer
 

I just built a new NUC for imaging and it appeared all the software was working except I'm not able to connect APCC environmental conditions to the Power box.  The NUC was loaded with the most current version of Windows 10 Pro and latest versions of ASCOM, Pegasus driver, APCC and V2 driver.  When I loaded APCC Pro I didn't see the black screen flash as it usually does at the end of installation.  

Typically the Pegasus box is available through the Observation Conditions Hub when it's installed and connected but it's not available as an option on the new build.  Everything else in the imaging train and software is working as expected.

Any suggestions?

Re: Flexible all-weather USB3 cable?

Woody Schlom
 

Christopher,

 

Yup, I found the same specs myself.  Interesting that the shielding is aluminum braid.  That alone might make these cables more flexible.  And also interesting is that the cable jacket is PVC – which usually stiffens up a lot when it gets cold.

 

At least for me, I NEVER intend to use the cables at -20° C.  My fingers don’t move at those low temperatures any more.

 

Thanks for your help,

Woody

You made me dig but I found it on their international website, oddly:
Lindy 36663 USB 3.2 Gen 1 A-B 5m:  24 AWG power and 28 AWG signal, 85% braid, 5Gbps bandwidth, 2.2" minimum bend.  Under Technical Details:
https://www.lindy-international.com/5m-USB-3-0-Type-A-to-B-Cable-5Gbps-Cromo-Line.htm?websale8=ld0101.ld021102&pi=36664&ci=800504

Yes, it was shipped from the UK and took a couple of weeks to my memory.  The cable isn't small/tiny.  The connectors seem pretty good and not cheap.  I'm happy with mine so far, but again I haven't pushed it lower than -12C so far.   I use it for my QHY5III290C video/guider camera.  No drop outs or issues noticed at high video speeds when I tried planetary work.
Yeah, not a $10 cable, but it feels better than any of the regular/basic USB 3 A-B's that I had lying around, and the final price was cheaper delivered to me in Canada than the L-Com cables were after UPS surcharges (bleh).  I think you should be happy unless you push colder than its -20C rating.

It gets to small digits plus or minus F° or ~ -20C a couple nights a year. So I would love to see a review on these cables. Usually some of our clearest nights.

Re: Flexible all-weather USB3 cable?

Woody Schlom
 

Christopher,

 

Thanks.  I’d already found them on Amazon and just blindly ordered a couple purely based on your recommendation.  So if I don’t like them – you may hear about it.  Can you live with the pressure of that recommendation? 

 

My initial reactions to the order are:  VERY expensive, and even though Amazon said they were in stock, they’re apparently coming directly from the UK – and the delivery estimate is first week of Feb. at the earliest.

 

I couldn’t find any detailed specs on the Cromo cables – such as wire gauge.  Based on the photos, the cable itself looks relatively thin to me (thinner than many of my L-com cables with the larger wire gauges and double-shielding).  So I’m guessing the wire gauge for the Cromo cables is probably 30/28/28.  Not the greatest for CMOS cameras that need all the voltage they can get.  My stiff PVC jacketed L-com cables are 28/26/24, and one of them even has #22 power wires inside.

 

Oh well.  I guess the proof is in the pudding and I’ll find out how well the Cromo cables work sometime next month.

 

Woody

Sorry, I should have provided a link to purchase sites for the Lindy:
https://www.amazon.com/LINDY-36664-Type-Cable-Cromo/dp/B07F6WHVLH/ref=sr_1_1?crid=1472ZRARBF8FH&keywords=lindy%2Bcromo%2Busb%2B3&qid=1642120850&sprefix=battery%2Bcapacity%2Bmonitor%2Caps%2C272&sr=8-1&th=1

at -12C both the Lindy Cromo cables and the L-Com cables becames noticably stiffer than when at room temperature, but not rigid.  I was not afraid of them cracking in use or when packing up in the morning.

Cheers!

Re: Flexible all-weather USB3 cable?

Woody Schlom
 

Christopher,

 

Thank you for all the detailed information.

 

I’m currently using several various L-com cables, but all the ones I have are made with PVC jackets.  And the double shielded, large AWG ones in particular are even stiff at 50° F.

 

And thanks for explaining TPE, PU and PUR.  I saw that L-com has some TPE cables both made up, and in bulk.  And I wondered if it was more pliable in cold weather.  But I’d have to make my own as the ones they offer made up are too short.

 

I’ve never heard of the Lindy Cromo cables, but will look them up.

 

Thanks again,

Woody

Look for TPE (thermoplastic elastomer) or PU or PUR insulated (jacketed) cables, which is are industrial cable insulations rated to -40C and colder.
PVC is typically consumer grade and gets brittle in the cold, as observed
I have made DC power cables from silicone insulated wire of the type used in model airplanes, cars etc, but it is easily nicked and cut, so I protect it with braided sleeving or other.  Silicone wire insulation also doesn't seem to be UV protected so is not recommended (by me at least) for a permanent installation.  I saw a friend's install for his portable RV solar panels go bad in one summer season when the insulation bleached and cracked.

L-Com has high flex TPE insulated USB 3 cables in this series but they are all short:  https://www.l-com.com/usb-usb-30-high-flex-type-a-male-to-type-b-male-cable
They also have PUR insulated high flex USB 2 cables in this series:  https://www.l-com.com/usb-high-flex-usb-20-cables-polyurethane-jacket-type-a-b-connectors
And high flex outdoor rated TPE Ethernet in these series:  https://www.l-com.com/ethernet-cat5e-rj45-tpe-utp-continuous-flex-outdoor-industrial-ethernet-poe-patch-cords

Be warned if you are out of the US that L-Com ships via UPS and UPS did line by line brokerage charges that ticked me off.  $67 in brokerage fees alone for a US$170 order of 5 line items.  Grrr.

Another alternative is Lindy Cromo USB cables available via Amazon.  They are a fancy audio cable maker from the UK and their Cromo line seems pretty nice.  Officially rated -20C to 50C operating range.  eg:  https://www.lindy.co.uk/cables-adapters-c1/usb-c449/0-5m-usb-3-2-type-a-to-b-cable-5gbps-cromo-line-p11357

Personally I have sets of USB 2 and 3 Lindy Cromo, as well as the aforementioned L-Com PUR and TPE insulated USB2 and Ethernet cables, but I have only used them down to about -12C before the skies tanked here for the season (Calgary AB). 

As for making your own, I have heard of people doing it but not tried it myself.  Connectors can be purchased from the likes of DigiKey.  Ensure you get the appropriately rated cable, too, and have good soldering skills as you will be soldering fine wires to small pins in close proximity and you cannot do a sloppy rats nest of bends at the connector as it could impact the signals.

All the best
