AP 1200 won't unpark via APCC

Dan Simpson
 

I've been enjoying good results using my older AP1200 (ser. # 1200410) for a year or so now. I upgraded last year to a CP4. I generally use ACP for automation and am using APCC and the V2 driver. The problem reared up starting last week while using ACP as I began to have trouble with plate-solving errors. The scope/mount wasn't pointing anywhere near where it should have been. First thing I did was to simplify and take out all of the complications so all of my recent troubleshooting has been manual, no ACP. 

I think I'm up to date with both APCC (Ver. 1.8.0.9) and AP V2 ASCOM 5.30.09.

The problem shows up on startup. I power up the mount and then open and connect APCC & AP V2 without problem. But when I click the Unpark button the scope using APCC  the APCC screen does not show the scope as Unparked. The Park button remains grayed out and the Unpark button remains active - but no matter how many times I click on the Unpark nothing changes. The weird thing is the scope is indeed tracking, it is visibly moving at a tracking speed. Also, the bar across the bottom shows the scope is tracking at sidereal and the yellow tracking/parked/stopped info display in the Telescope Position section shows as Tracking. However, I can't get the scope to move using the APCC buttons in the Move Scope section.  I've pasted a screen shot of APCC and V2 at that point. 

One other piece of information is that the keypad continues to function. I'm able to Unpark and Park as well as do Goto's to objects in the the keypad catalog. I did find I can use V2 to send the scope to all Park locations (but not using APCC) however the scope does not actually Park as it then continues to track out of the Park location.  

I know I'm forgetting some details, I was up all night working on this. I am certainly open to any all suggestions.  
Thanks in advance,
Dan

The 400GTO was a super little mount.  I have  friend that used an AP Traveler with a SBIG ST-8 on an AP400 nearly 20 years ago.  It was a nice portable setup.

To which we effectively add an encoder for RA and on which the RAPAS is installed. If she weighs around 20 lbs (without CP bar) and she carries 30 lbs it would be great. It should be remembered that the Mach1 with these 29 lbs is indicated to carry 65 Lbs.

I've got an AP40GTO for my travel setup. All I can say is, "It sure is  a nice mount!" The AP literature says it can handle a 5" refractor, I've got a 4" refractor on it. I read somewhere it has a payload of 18#, which seems a little light. I have 28# on it all set up ready to go, and it acts like there is nothing on it! Love it!!!

I would agree with your comments above, maybe with an additional option that I took.   And this is to donate it a scope to your local library for checking out.   Now it all depends on the size and dedication of the staff at your local library as well as the complexity of the scope.   I recently purchased a 4.5" Star-Blast and performed some modifications as defined by, I think a Canadian club, and donated it to our library.  I  trained some of the staff at an outreach event.  Until covid-19 hit, it was being checked out continuously.  The only problem is that we had one overly-inquisitive person take apart the zoom eyepiece and put a big silver fingerprint on an internal lens,  which required me to take it apart and clean it.   Other than this, it's gone well.    Not sure this kind of program could apply to something as complex as an A-P equatorial mount and scope.

Use of Dielectric Grease for Mount Connections

M Hambrick
 

I have read a lot of posts where corrosion in the various cabling connections has been mentioned. Given the possibility of heavy moisture accumulation on the equipment from dew, what is the conventional wisdom on using dielectric grease on the connections on the mounts; specifically for the motors and keypad, and (if used), the RigRunner connections. This material is widely used on the various electrical plugs under the hood of your car, and it seems to be pretty effective. Any specific recommendations from the A-P folks or other forum members would be appreciated.


Re: Which to Choose; Absolute Encoders or 92 mm Stowaway

Joe Zeglinski
 

Hi Michael,
 
    Yes, I’m Canadian. Although long- retired,  I never was a scout, but for the past 17 years, I did help a senior, who volunteered as Editor, in the Polish Scouts organization. It was fun to help with photo editing and PC support, in publishing their semi-annual magazine. I sometimes suggested to her, that the boys and girls, scouts,  who contributed articles, should get more involved in actually producing their magazine, to earn an “Editing Badge” for their hard work. Maybe it could lead them into Journalism some day. But, I was informed that “creating any new badge”, requires permissions of the International level “Baden Powell” organization, in London (?), so it is rarely done. I hadn’t heard that there even is an Astronomy badge. Perhaps those here didn’t either. But, I’ll pass this on, in case they aren’t aware of it either.
 
    However, I am very glad to read that there is a badge for Astronomy. The tasks you outlined are impressive.
Thinking about having scopes, and earning badges, in such organizations, reminds me of the quote: “ The mind is not a Vessel to be filled, but rather a Torch to be lit ”.
 
    And so it would be for the kids becoming interested in Astronomy and other science & maths skills.
These are the new generations, for whom ... “Outward Bound”, may have an entirely new meaning some day.
 
Joe Z.

I had a similar dilemma a couple years ago when I posed a question to George whether to get a better mount (I was using an A-P 800 at the time), or to get a better camera. He advised me to sell my 800 mount and get the 1100. That was very good advice and I have never regretted the decision to get the mount.

As you mentioned in your previous post, it often turns out that the financial controller releases more funds later on. This is exactly what happened before. I bought the 1100GTO mount, and then about a year later she let me upgrade my camera.

Good Points Joe.

Are you Canadian ? I ask because you mentioned Scouting International.

Anyway, the Boy Scouts of America offers an Astronomy merit badge that the scouts usually take at the summer camps. The requirements are pretty comprehensive. To name a few they must:
  • Describe the different types of telescopes including those that observe light beyond the visible spectrum, explain the purposes of at least three different types of instruments used with telescopes, and describe the procedures for cleaning and storage of telescopes and binoculars.
  • They have to identify in the night sky at least ten constellations including four that are in the zodiac.
  • They have to identify eight conspicuous stars, at least five of which are magnitude 1 or better.
  • Identify at least one red, yellow, and blue star and explain what makes them different colors.
  • They have make two sketches of the Big Dipper with the North Star at least four hours apart showing their orientation in the sky
  • List the five most visible planets in the night sky and note the ones that can be observed in phases. Look up (internet / book) to see when they will be visible.
  • Sketch the full moon and show at least five each seas and craters
  • Sketch the phase of the moon on at least four consecutive days at the same time and place.
  • Visit a planetarium or observatory and make a log book of what they saw.
  • Plan and participate in a three hour (minimum) observing session using binoculars or a telescope. List the objects observed and find each on a star chart
  • Investigate career opportunities in astronomy.
This is just a sampling of the requirements, but I was pretty impressed with what they were asking the scouts to do. You would have to agree that these activities would be a lot of fun to a scout who has an interest in astronomy.
Unfortunately, many of the summer scout camps are nothing more than merit badge mills, and even more unfortunately most of the counselors that the camps hire for the summer are just college kids looking for summer jobs, and they know little or nothing about the merit badge classes they are teaching. This is where the adult leaders (i.e scout's parents) come into the picture. The Boy Scouts have always tried to get the parents of the scouts engaged in the activities of their children's scouting activities, but unfortunately again there are far too few parents who will do this. Most just drop their kids off at the scout meetings and go out for a dinner. They see the week long summer and winter camps as an opportunity to take a vacation away from the kids. It is really sad.
Some of the scout camps get some extremely generous donations. At the first summer camp my son (an Eagle Scout by the way) attended they had two complete Celestron telescopes, a C8 and a C11 ! Unfortunately, the counselors had no idea how to set up and operate the scopes. Luckily I was there for the week and I was able to help them out, and I think the kids had a really good time on their observing nights. For the other seven weeks of camp sessions, the camp might have been lucky enough to get help from a knowledgeable adult leader for maybe one or two of the sessions at best.
Scouting has gotten a really bad rap in recent years. Some of it is deserved, but it is getting harder and harder for Boy Scouts to compete with the other things that kids are into. I think that a lot of this is the parents fault.
Sorry, but I kind of rambled on with this.

Very well said, Chris,
 
    I never thought of it, but you are right-on.
Besides, an excellent scope and mount,  like those from AP, will eventually pass from hand to hand – as teachers retire, or the kids move on to more advanced equipment as it comes along.
 
    In the same vein, wouldn’t it be grand if Scouting International, established a special ASTRONOMY Badge, rather than something just relating to “outdoors and camping”. Maybe in the future they might concentrate less on finding their way through the forest – probably just streets, when we run out of woods -  than on travelling on pathways through the skies, as man’s journey inevitably reaches even farther afield, for our next generations.

Personally, I believe that we should...  
 
NEVER GIVE TELESCOPES TO SCHOOLS.
 
GIVE TELESCOPES TO TEACHERS OR STUDENTS INSTEAD.
 
If you give it to a school, it inevitably ends up being controlled by school middle-management bureaucrats and spends the rest of its life in the back of a crowded supply closet, never to be seen by kids ever again. The tax write-off for giving it to a school will end up being next-to-nothing anyway.
 
If you give it to a dedicated teacher, that person is much more likely to learn how to use it properly and take it with them throughout their teaching career.
 
If you give it to a dedicated student, that person's life will be changed forever.
 
If it is a big, expensive, complicated telescope, consider selling it to another astro-nut who will love it, or work to establish an NPO in a local community to operate it, put it in an observatory, and perform outreach.

That is a great suggestion. I have also thought about donating it to a local school. Only bad thing is I kept the pier to use with my 1100 mount.

That's probably just unwinding the cables.


I think you could take a series of pictures of polaris for several days at the North Pole.

Won't the motor trip a fault and stop if it hits with the clutch tight?  I think I remember that happening to me once when my meridian flip time was off a little bit. 





Thanks,
Charles

Good to hear. But my clutches are snug tight with a key. I am getting in tonight to see what the fall out is if any.

Did I do any damage?
Probably not. Especially if your clutches were not super tight.

I left my Mach2 running all night last night, forgot to turn off power. This morning the scope was up against the pier. Nothing damaged except my self esteem. ;^(

Hi All,

It happened while I was sleeping and it was tracking on its target. I think it crashed maybe 5-10 min before I intervened. Did I do any damage? It scope is at a remote observatory 2100 miles away and can't get there to investigate.
