Trouble staring APCC on second computer

Geoff Smith
 

I tried to install APCC on my Fitlet2. All seemed to go OK until I tried to start APCC and then I got the attached message. Any suggestions as to where to go from here?Does the same license key work on different computers?

Ha, no, although I do sometimes call her “Little Miss Muscles“, because as a French bulldog, she really is a little bundle of muscles in her legs. The “Mr. Muscles“ I was talking about is my burly son, whom I can always count on when my no longer youthful strength won’t get the job done.

Re: knock on direction reversal #Guiding

Yup. I get that. I just hit this noise situation after adjusting the worms for backlash.

I think I figured it out though. The worm adjustment was too tight. When I loosened it up a bit (by turning the spur with the worm lock slightly loosened) the noise went away.

Subject: [ap-gto] knock on direction reversal #Guiding

I've been trying to isolate some issues guiding my C11 on AP900 that look like might be backlash (strangely... in RA).

I just re-seated my RA worm (I did this 5 or so years ago). 

I just noticed that when I reverse directions at maximum slewing speed, there is a significant sounding 'knock' from the gear box. I don't remember this before, but maybe I'm just paranoid. 

Should this be quiet or is a noise on reversal ok?

Re: knock on direction reversal #Guiding

 

Hi Pete

I don't have an answer for you on the knock sound, but generally backlash is not an issue when guiding in RA. it's tracking in sidereal, so the axis will slow down or speed up in response to guide commands, but never reverse.

If you have a guidelog that may shed more light on your problem?

What do you have on your 1100/Planet?
The biggest at present is an AP1100 with a C11.  With it sitting flat it is very stable, the actual worst part is when it is empty, just the mount, as the mount's weight is a bit off center, so if I am loading the tripod + mount onto a handtruck (which I do every morning) I need to make sure I do not tip it too far when raising the light leg.  Or more precisely, I try to always have the mount's heavy side highest, so I lift it first, and lower it last. 

But imaging it's great, fairly low (the top of the C11's dew shield is probably still almost 6.5 to 7' up so hardly low). I wouldn't like to use an eyepiece with with the ota aimed high, but the camera doesn't mind being near the ground.  

I'm a big fan of that planet, very light and portable but still dead to vibrations and strong.

Re: FrankenScope Stage I Step 3

Howard Ritter
 

I’ve been thinking about the height because I’d like to, as you suggest, preserve the stability of the tripod and have a lower lift to deal with when assembling and disassembling. Though I plan to do this cycle only twice a year, once here and once in FL, it might be that I’d want to put this 155 back on from time to time for imaging purposes, and I’m sure both my back and my son would appreciate the lower height when we’re wrangling the Meade 16” OTA, which is the whole purpose of this project. 

The more I think about it, especially with the 16” in place, I think this height should be workable. It might require using a chair for observing objects high in the sky, but for imaging it’s irrelevant.

Speaking of the 155, if inflation ever deflates and the stock market zooms up again (!), I’d like to put it on an 1100. It now sits on its original 600E mount on a (replacement) Planet, and I was wondering whether that tripod would handle the mount. I guess you’ve answered my question. What do you have on your 1100/Planet?

The main problem I see is that the sled dog you have ready to tow the mount into position may be a little outsized by the load.  :) 

Incidentally, and a bit more seriously, why extend the legs when you get out in the field, isn't lower more stable, less wind, easier to lift stuff up to it, etc.?  I keep my planet all the way down (with an 1100) and proportionally it looks about the same height, maybe a bit taller.

But that is one beefy tripod, that's for sure.

Thanks you, I will give that a try and get back, it's going to be a couple days before I can make it out to my observatory though.

Re: APPM - Dome Settings - Offset Question

Ray Gralak
 

Or have I missed something in how to use the "Passive"
option? Thank you!
Unfortunately, the ASCOM Dome API is very low-level and does not provide any support for telescope offsets. You might try installing/enabling the legacy "POTH" in ASCOM which can act as a hub to allow multiple applications to connect to a dome's ASCOM driver.

Re: FrankenScope Stage I Step 2

Hi, Chris—

Do you mean you have just the Meade OTA, and that’s why you need to find a tripod? I can’t imagine they’re very plentiful on the used market, unfortunately.

If you get lucky, you’ll be glad to know that the bolt holes in the A-P Flat Surface Adapter nicely avoid the cast structural webs on the underside of the tripod head when the FSA is centered and the N is aligned with one of the legs.

Good hunting!

Rehabilitation of the Meade Giant Field Tripod is done except for the cosmetic removal of surface rust on the legs.

The A-P Flat Surface Adapter is mounted with 8 socket-head bolts to holes drilled in the top plate of the tripod.

The 1600GTO sits on the carpet, observing the proceedings as it awaits its ascent to the throne…

…which will probably have to await a visit from my son, who has muscles. Maybe tomorrow.

Re: AP900 CP4 with ASIAIR - need some guidance

Kevin Cook
 

Hi Dan - I don't know if this will help in your situation, which is a little different than mine. I am using a Mach 1 mount with the CP3 version.  The mount is connected to my ASIAIR PRO via an RS232 cable (on the CP3 side) to the ASIAIR (regular USB connector).  When it works, it works like a charm for polar alignment, plate solving, and guiding.  Where it gets squirrely seems to be when I power up the mount first, then power up the ASIAIR - that is when the mount motions go seriously astray, sometimes starting with that first polar alignment rotation of the RA axis.  It seems as though the ASIAIR does not know when the home position (Park 3 for me) is, so all subsequent motions are out of whack. Things go much better when I power up the ASIAIR first, make sure I hear it beep that it has set up its little local wifi network, then I power up the mount and open the ASIAIR app.  No guarantees it will resolve your issues, but give my recommended startup sequence a try.

   Hi everyone,

since yesterday I am a happy owner of an AP900 with CP4 upgrade. What a beautiful an impressive mount! 

Coming from a Skywatcher AZ-EQ6 driven by an ASIAIR using EQMOD, I tried to use the AP900 in the same way.

I connected the ASIAIR to the CP4 with an USB cable, an turned everything on. After choosing "Astro-physics CP3/CP4" in the mount menu of the ASIAIR, the mount was instantly recognized and reacted to the arrow buttons on the phone screen. So far so good.  I then tried to simulate a full imaging session.  Everything eventually worked but there was some oddities:

  1. When I ran the polar alignement procedure, after the first plate solve the mount moved in RA (as it should) but the displayed angle stayed at 0° and the motion stopped then midway. To remedy this I had to first point the mount away from the pole, take a picture, sync the mount, come back to park 3 position (all with ASIAIR), before launching PA.
  2. I sent a GOTO command with the ASIAIR to M13, which was then 1h30m east of the meridian. However the mount moved in the "wrong" direction and ended up counterweight up (fortunately the scope cleared the mount - but not by much). I sent after that another GOTO command to M51 (which was about 2h west of the meridian) and this time the mount was in the standard position, i.e. counterweights down.
  3. I tried to calibrate autoguiding. The West steps were as they should (small), but when it reverted to East, the mount made a very large motion (enough to put the guide star out of the FOV). I tried then to enforce guiding speed 1x with the GTO keypad first, it worked but only to some extent (the star was lost but eventually found).
I managed to take few autoguided frames and the results are very encouraging - significantly tighter stars than with my previous mount. 

I am wondering whether there are extra steps or settings that would make the dialog between the ASIAIR and the CP4 smoother ?

Thanks for your help,

Dan
