Re: AP1100 park position question

Jack Huerkamp
 

Christopher,

 

The company is Linak out of Kentucky and the columns I used were the DL2 2500 Newton rated.  My original ones were rated at 1000 Newtons each when used with a non AP mount.  With the AP1600 and 150# of equipment on the dual column setup, I changed to the 2500 Newton thrust each – 5000 Newton total thrust.

 

DL2: Robust lifting column for desks, workstations and kitchens (linak-us.com)

 

Yours truly,

 

Jack

Lymax columns. A lot cheaper to buy Lymax off of Ebay or wherever and make your own telescoping pier.

I have used Park 4 for several years for exactly the roof height issues that you are evaluating.  This is for a 1100 mount with a 14 CDK scope.  There have been no problems.

I have a PierTech height adjustable pier (http://piertechinc.com/telescope-piers/).  When I need to tinker with equipment, I lower the mount and move it to P3, where it clears the roof. To remove equipment, I loosen the clutches (older style 1100) and rotate/lower the OTA to a separate support table before loosening the dovetail.  I normally leave the pier at almost max height, in order for the roof to clear on opening.

The adjustable piers are actually from another company, but I have forgotten the name.  I think Chris Erickson has these.

I use Park 4 in my ROR and have done this for years. I did design the ROR so i can freely move the mount in any direction with the roof closed. Very helpful to be able to put it in Park 2 or 3 with the roof closed.

I have an ASI-1600MC Pro on a TMB130SS f/7 APO on an AP1200. I usually shoot 10m subs. For galaxies I often use Pixinsight's HDRMultiscaleTransformation to recover core detail. Here is my attempt at M81 and M82: http://astronomy.mdodd.com/galaxies-18.html

It's easy to get carried away with HDR. I've attached a screen shot of M81 where I went way too far.

Thank you your feedback Joe. This is exactly why I was asking this question. Stability also implies undue strain as you point out.

More APPM Results -- Can Someone Help Me Understand This?

mjb87@...
 

Running an APPM session with a f/10 (native f/15 with 0.67 focal reducer) Cassegrain on an 1100 using an ASI1600MC-Cool. Image scale is 0.26 but because this is a OSC at Ray's suggestion I used 0.52 for both X and Y scale. Other settings were generally standard except the max catalog magnitude was reduced to 12. (This seems to avoid a lot of checkpoint timing errors.)  This was during a half-moon almost directly overhead. Not ideal conditions. A bit of wind. I can't figure out how to manually set temperature, pressure and humidity so the default of 10 was used when it was closer to 18.

The run on the east side made sense. Most errors with a couple of dozen arcminutes. 



Things went crazy on the west side, reporting pointing errors of 10 or 15 degrees!



I installed this model and then pointed in the west and did a plate-solve and recal and got an error telling me the platesolve-based correction of 15 degrees was more than the maximum allowed. So something is wrong here.

The physical setup of the telescope on the mount seems appropriate -- for sure no 15 degree misalignment in orthogonality. The primary mirror is fixed. Collimation is good -- checked a week ago. The polar alignment is good -- ran a session with Polemaster yesterday and checked with RAPAS today.

Am I missing something obvious here?

In my experience, certain hydrocarbon fumes (both pre and post combustion) will damage many plastics and rubbers,  both natural and synthetic. The damaged hand controller cable is a hint.

Fumes related to diesel and kerosene seem to be especially hostile to cables and connectors.

Nice to have the new CP4 and new key pad. If you still have the old one, you can check to see if you have a bad connection or broken wire in the key pad cable or maybe a bad connection in the cable plug where it connects to the key pad circuit board.
The keypad has no effect on the operation of the mount. The keypad is normally silent and has no interaction with the mount unless you, the user, sends a command to the mount. If you send a slew command to the mount and the mount runs away, the keypad is not involved at that point. You can unplug it and the mount will continue to run away. This is strictly an internal controller issue where the CP3 is not getting encoder signals from the motor and is thus spurring the motor on in an effort to turn it on.

I do not know what happened with my older GTOCP3 and/or keypad, but it went crazy because it stared very fast movement of the mount in RA whenever I pressed ANY button, even STOP one... this was very dangerous. I checked all cables, etc., but nothing helped. In any case, I am very glad to have GTOCP4 now.

GTOCP4 Caps

Edited

I’m curious if anyone knows the sizes or if any AP personnel would post the sizes of the connectors used on the control box.  We use these in aviation to cover unused connectors, and I think I would like to try a few since the plastic ones don’t really stay in place.  The sizes listed on shopping sites are gibberish and mean nothing that I can discern.  Or does anyone have a good cap, or covers, they have found that work well.  I move my mount each time I set up and they tend to pop off.

yellow diode raised - motor stall although telescope was precisely balanced
Yes, all this will happen if the motor encoder is disconnected and not working. If new cable fixes this, then that is where the fault is located. If it does not fix the problem, then the motor must be repaired.

Unfortunately, I didn't use my mount mostly two years... due to our movement to a new house and building my new observatory.
Than, I found that keypad's cable black plastic tube completely fell apart, so I bought a new one. When I tried mount two weeks
ago after so long time, it worked as I already described and also yellow diode raised - motor stall although telescope was precisely balanced in both axis. Have to say, that mount was at home all the time when not used.

I also bought a new Y cable, so I will try a new setup probably tomorrow and let you know.

Thank you,
Jan

Nice job Kevin!  Other than the short exposures, did you have to do anything special in PI to avoid blowing out the core?  I've been thinking about getting one of those cameras...
