APCC PRO upgrade from Standard

Keith Olsen
 

I don't know where else to ask this question so I came here.

Is the APCC Pro upgrade a new seperate application or does it overlay the Standard version and keep the settings from the Standard Version?

Thanks,

Keith


Re: Has Notification Started?

Karen Christen
 

Hello Larry and all,

We have not yet started the notification for the second run of Mach2s.  At present we are focused on making final edits to the Mach2 manual, updating the Keypad manual with a variety of new functions, taking orders for a run of 130GTX scopes, and assembling and shipping the last few mounts in the first Mach2 run.  Fear not, however, as mount-making progresses.  Since June 1 our production staff has been hard at work moving the second run through the process so delivery of these mounts will be delayed only by the 10-week Illinois coronavirus shutdown.  To answer a question that was floating out there recently – all first-run Mach2s were offered to people on the old Mach1 list.  We have not yet started on the Mach2 list that begins 4/4/2019. 

We love and appreciate your anticipation.  Please hang in there.

Marge, the first of June you said that you expected to begin notification for the next production run of Mach2's later in June.  Has that started?  The reason I ask is I thought I was close to the top of this list and if you had started notification and since I have not heard anything then perhaps I am not as high on the list as I had hoped.

Writing back just to close the thread on the resolution of my issue. I've found a solution but just reporting back to minimize the rebuilding of wheels for anyone else is having issues.

I picked one of the images that Platesolve2 wouldn't solve during the APPM run the other night and loaded it into different programs. 

1. Astrometry.net (nova.astrometry.net) - image solved 
2. Stand alone version of ASTAP - solved in less than a second
3. Stand alone version of PlateSolve2 - solved in a bit over a second
4. Opening the image in SGPro with ASTAP solving (right click on image) - solved, about a second
5. Opening the image in SGPro with Platesolve2 solving - solve failed

I created a profile in SGPro using ASTAP as the default plate solver for APPM and the mapping run completed in nearly half the time needed when using PlateSolve2.

The same folder as the logs. BTW, when APPM is collecting data if the image has been saved you can double-click the failed line in APPM and the FITS image will be opened in the default FITS viewer on your computer.

Usually full-frame results in better accuracy than 1/2 or 1/4 in my setup, but I'm not sure if that is universal. Using 1/2 or 1/4 center may or may not speed up plate solving as there might be 4x or 16x as many spiral plate solve attempts, and the max solve count for PlateSolve2 may be reached sooner.

I used platesolve2 for a long time as my plate solver in SGP.  As a result of a forum discussion (here as I remember)  about using ASTAP, I have switched to ASTAP (it was easy) and found that I can plate solve much faster and I think it works very well with APPM, returning points faster.    I like it better than platesolve2.   Consider switching to ASTAP if it seems slow with platesolve2.

Thanks for the post Greg, I should have started reading at the bottom.   Someone else recommended ASTAP and I think I need to finally try it.   
I usually get solves on the first plate in platesolve2, after my first solve, but still it's slow.   I find that during normal imaging, the whole efficiency with SGPro and my ASI camera seems to be a lot less than optimal.. I seem to loose a lot to overhead with an ASI1600 camera.

Ray, have you tried using SGPro and platesolve2?   I did not get 2-3 points per minute.  I was maybe getting 1 per minute average.   This accounted for the fact that some points (maybe meridian) needed to be solved multiple times (twice only I think).   So while each solve likely took less than a minute, with the central points that needed to be solved twice, it averaged out to 1 per minute.   
 I always shoot at 1X, but have do have usb3 download.  One of these days I'll try binning, but I've never thought binning on a CMOS camera did anything at the camera for efficiency.

SatelliteTracker was sold back to the original developer/owner and renamed to SkyTrack.
SkyTrack is now under development with an ascom connect.
$9.00 license
I ordered SkyTrack today and have not received license and have not tried SkyTrack
 
I still use SatelliteTracker v2.51 direct connect pc to CP3 on Astro-Physics 900GTO

I think you should record a PE curve and turn on PEM. Nothing to lose, but possibly something to gain. Even though you're getting decent results now, why not use PEM to potentially improve things, even if only slightly.

If things get worse, you can always turn off PEM. But at least the curve is in the mount, ready to use.

Re: Should I record a PEM?

Roland Christen
 

Yes, definitely record a PE curve and then turn PEM ON. You can record it with your main camera on your scope, and you will be accurate, even at your short focal length. Don't record the pE curve with a short guide scope or finderscope.

Subject: [ap-gto] Should I record a PEM?

I'm successfully using APPM in the early evening to map 23 points or so. I have to say, not having the autoguider makes everything so much more reliable and fast. There's no need to "plate solve and center" on a new target -- it's always center of the frame in SGP. I'm also in a very forgiving system with a wide field and old camera.

I'm sorry I didn't buy APCC Pro back when I had a discount offer with a new 1100GTO. I didn't think it would serve any purpose when I'm not in a fixed observatory. I was very wrong!

I've been shooting a Messier survey from home in Los Angeles County. Not because my shots are interesting or especially good, but because I can. :) Doing this has given me tons of experience with the entire process from set up  to final image processing, by repeating it frequently. I've captured 47 Messier objects in the past two months, about 30 minutes of imaging time on each, with an old one-shot color SBIG camera.

I have two setups: My small system is a very old (first run) Mach1 GTO with an AP Traveler 105mm f/6. The big beast is an 1100GTO with an AP 180EDT. I haven't been using the big one so often because taking it down involves waking up my wife at 2:30 to come out and help me lift it off the rings and stow it. She's been very willing for the most part, but I save that for special occasions.

The Mach1 has a few enhancements, like the updated Alt-Az base, and adapter for the RAPAS scope. I've upgraded the CP3 to the V2 chip, so it works beautifully with APCC Pro. It does NOT have levers to disengage the drives from the gears, so I'm not able to do a delicate balance on the Mach1. But the system is light enough that it doesn't seem to be critical.

Since I upgraded my CP3 controller chip, I've been running with PEC OFF.

Finally my question: This system is very forgiving, with a huge wide field, and 2.45 arc-seconds per pixel. That's a little bit high compared to the recommendations for recording a PE curve in PEMpro.

Should I bother?

Re: Should I record a PEM?

Christopher Erickson
 

Roland and Ray will certainly give you the best and most useful answers but I'll throw in my two cents because I am in a sharing mood right now.

On lights of exceptionally-bad seeing, I have experimented with PEM training runs, just for fun and self-teaching.

My experience has been that running about 7 to 10 worm turns results in pretty good and even excellent PEM training, in spite of the bad seeing. Exactly like combining a lot of subs to minimize noise. This success is certainly partly due to how smooth the RA worm gears and wheels are my Mach1 and 1100. Cheaper mounts with sharper changes in periodic and random tracking errors might not give the same good results. Make that WILL not give the same good results. LOL

Joe,
I too had to clean a TV remote control with this problem. Thanks for the photo.
There with the AP keypad I went there quiet. I'm not sure I have exceeded 95 °F (35 °C).
It was not a thermal stripper and I think the problem may return.

Re: North Keypad button problem

Joe Zeglinski
 

Dominique,
 
    Don’t want to scare anybody about this problem  – but I would be VERY careful – with using a hair dryer on your expensive AP Keypad. 
If it helps momentarily by cooking the oil, perhaps bubbling it away from the carbon contact, then it might also do the same for the rubber button tops. Those are very thin skinned rubber tops, which you don’t want to become stretched, floppy, or torn.
 
    Whenever I took a “marginally working” keypad membrane out of some misbehaving “remote controller case”, the circuit board pads were “quite slimy”, almost dripping, when I got it on my fingers.
 
    For example, zoom in very tightly on my attached  picture of my old Panasonic Cordless phone circuit board cleaning, when one of the keypad digits wouldn’t make a good contact for me to dial out. You can see fairly large, round drops of oil at the far left edge of the circuit board, especially next to the FLASH key pad,  and “puddled islands of oil”,  where pressing the other buttons, squirted  away some oil between the circuit pads in other places. Since we hold such devices “upright” during use, I think the oil eventually accumulates more toward the bottom edge, as seen in my picture – and this one wasn’t really bad yet, with just one button losing connection.
 
    The dark backside (buttons) of the membrane itself is a bit harder to see how wet it was, but it was all a big mess. It is NOT an “intended” button lubricant ! – I have seen circuit boards & keypads  bone dry, on newer devices I have taken apart to check.
 
    I haven’t needed to wash the oil from my AP-900 & 1200 Keypads yet, since I rarely use them, so I can’t speak about any difficulty of doing the same procedure there. But, this will give you some idea “what really goes on, under any”  of our common household Remote devices. Most people aren’t aware of such things, and simply throw away the device, and (hopefully) can still buy a new  phone handset, TV Remote, or a substitute etc.
You don’t want to do that for the AP Keypad, and nobody warns us about this “common” problem.
 
Joe Z.

Hi,
It may only be part postponed,but if they were oily structures stuck on contacts and preventing the activation of the button, one could think that a dose of heat could thin the thing. So with the screen and the buttons down, with a hairdryer, I moderately heated the "N" button, for 1 to 2 ', 2 to 3 times, and then I tried again and on the 2nd press on the N button the Dec axis started to move. After several tests the button remained operational.I will therefore follow its functioning on my next outings and I will inform you of the situation.
