Hi Linwood

Actually, Astro-Physics offers a set of plastic covers for all of the connectors on the GTOCP4/5 and the mount motors. You will have to call them to order a set. The interest in the metal covers is because they are more durable, and they will stay put, but as a minimum you should get a set of the plastic ones. I think they run about $15.00.

Re: APPM model how many points portable?

Jim Grubb
 

I have the 1100 with encoders and have found a very successful very quick workflow using ASTAP-SGP-APPM.  You can turn off blind solving and it will very quickly move to the next point if it fails.  This is useful as I have the same issue with my horizon map not being perfect.  When the scope is pointing at the trees or the house, it just fails and quickly moves onto the next point.  This only happens for me near the horizon.  ASTAP is by far the fastest solver I have used and usually solves in under a second so you can turn the "Max Solve Time" parameter way down and it will fail very quickly.  I currently have mine set at 10s and am sure I could lower it to 2 or 3 seconds with no issues at all.  You may need to do a blind solve when you first set up the scope before you begin the pointing run.  [Screenshot: APPM - Plate Solve Settings Page]

On to the topic of how many points.  If you are only going after one target in an evening, you can run a narrow line at the declination of the target you are going to be imaging.  I typically use two lines spaced close together.  Here is an example of an 88 point model which covers 7 degrees of declination.  I can run this model in 1/2 hour.  And this is overkill, way more points than needed.  [Screenshot: Pointmap 1 example]

If you pull back on the RA spacing and tighten up the dec so that it only runs a single line of points at the exact declination of your target, you could get this down to 27 points, which on my rig will run in about 10 minutes.  [Screenshot: Pointmap 2 example]

Good luck!
Jim

As you experiment with different spacing, you will start to get a feel for what works.

Hi Steve,
Dave asked me to write the response.  I have attached a simple drawing in a PDF that he provided.  The good news is that the 6 perimeter holes are NOT through-holes.  The only 2 holes of possible concern are highlighted in the drawing.  I'm guessing they were covered by your plate.  For cleaning the holes out, he suggested using a 1/4-20 tap.

Hello Howard,

Here are links to the Hirose covers. 
I suppose the two small ones would also fit the CP5 (keypad and power), right ?

What model would you recommend for the RA and DEC threaded connectors as well as those one the Mach2's back panel ?

Hi Shailesh

I am joining this conversation late, but I thought you would be interested to see a picture of Roland's 175 EDF at his Hawaii observatory on a 1600 GTO mount that is stored in the Park 1 position (counterweights horizontal with the scope facing north).

My family rented their house for a vacation a couple of years ago, and he was gracious enough to allow me to use his scope to do some imaging with the specific instructions that the scope and mount absolutely had to be in the Park 1 position in order to close the roof of the observatory.

As someone waiting for a mount, I’d love if I could just add a package of “covers for every opening” covers to the order, even if they are resold at a markup, it would be very convenient.

Re: Strange behavior with Mach 2 and MaximDL auto pier flip #ASCOM_V2_Driver #Mach2GTO #Guiding

Hi Brad,
I can't help much on the Maxim side, but regarding the AP V2 driver, I'll mention two things:
  1. I'm sure you are aware, but just in case, the pier side is displayed on the driver's window just above the direction buttons.
  2. You can verify in the log files with a search for   :pS#    (tell the search to match case).  The response is coming directly from the GTOCP5, and will be what the driver reports to all other software.

platesolve2  IS very slow.  Use  ASTAP.  Try  NINA and ASTAP combo. solves are always under 2 seconds for me.

I have a RAPAS on my 1100. I run lots of wires (around 6) through the mount and no issue. There is a plastic segmented "separator" that comes with the mount that allows you to run the cables through and keep them clear of the RAPAS. The reason I have so many cables is I have two interchangeable setups....one for a 6" APO refractor and another for a 11" SCT equipped with Hyperstar so one set is used for each to make it faster to switch setups without rerouting wires. I also have  wires for wireless focuser power. Of course you can also run external wires like I do on my 900 mount if you run out of room. For a permanent setup internal wiring makes it neater but for a portable mount it takes longer to run all the wires through instead of just hanging them off the mount and restraining with Velcro ties.

Re: GTOCP4 Caps

M Hambrick
 


What a coincidence ! I also ordered some of the caps from Mouser yesterday. They must think there is a run on the Hirose connectors. I checked the Digi-Key web site that Howard provided the link to, and it said that there was zero stock of the RM15TR-C(71), and also that they were obsolete. I checked Mouser again and they had both types of caps in stock, so I ordered several of each. The last time I checked the Mouser site, they were also out of the RM15 caps, but were expecting a shipment in June. The shipment must have come in early.

Unless someone knows of another manufacturer of these caps besides Hirose, it would be a good idea to grab some up from Mouser while they still have some in stock.

I would still like to find some caps to thread onto the RA and Declination gearbox motors on the mount. I have not had much luck finding anything.
 
I expect that Astro-Physics' master machinist could easily fabricate whatever caps we might ever want, and I would happily pay for them.

Don,

 

When I purchased the original pair of lifting columns from Linak, I was over the engineering department of the local public works department in New Orleans and we did a lot of custom fabrications for all of our facilities.  As such, I was able to have them sell me two 1000 Newton columns and the associated controls.   Since I was already an established customer, I was able to get an upgraded set of 2500 Newton columns and associated controls last year.

 

I do not think Linak sells to the general public.

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.

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.
