Re: Pier for 1100GTO #Guiding

"It looks like the sides were rolled to produce the shape."

Don, yes/no. I had a boiler-maker make it but there was no roller. A press was used to progressively make small bends to form the shape. I made a cardboard template with bends every 4" for him to work to. I do like the pier that results. On a different scope I replaced a pipe pier (8" dia, 60" long) with a similar tapered pier with great improvement. That one had a 16" base tapering to 6", 60" high but was asymmetric - the Nth  side was flat so the equipment C.O.G. was kept over the pier foot.

Made of steel these piers are quite heavy, but not intended for portability! Could be made of aluminium of course.

As mentioned a straight sided tall pyramid pier would probably be just as stable but has greater bulk higher up where it might affect a long scope.

Len,

Running APPM with CW up region for the first time.  It's funny, but I had to be careful walking around the scope that I didn't block it when it's taking images when CW up.  Haven't had that problem much before.

Ray,
 
   Just to be clear,  I think that was a user resettable option checkbox, so should confirm it anyway in the AP ASCOM  driver.

I forget to answer this. The driver will by default convert a TheSky6 Sync to a RCAL.

Yes, the link I gave is exactly the same information as in the driver help.

 

> But it's only a PNG image of a handset. How does one invoke an actual operational handset window?

 

If you scroll down, it shows you how to configure the handset window to open automatically when the driver is activated by an ASCOM client application. Is this not what you want to do?

 

Also, the first section in the “HandBox Window” folder is “System Tray Icon”. From there you can immediately open the handset window and perform other things.

 

Here's a screen shot. If this is not what you need, let me know.

Re: Starting with counterweight up in SGPro #Mach2GTO

Ray Gralak
 

I guess the more fundamental question is which does the Mach2 go to when asked to slew to these
positions where there are two choices? is it the nearest one?
If the East and West CW-up positions overlap and CW-UP is enabled for both sides, APCC will choose to stay on the current pier side.

When I ask SGPro to center on my target, how do I make sure it picks the CW up position?
You would have to map the East and West CW-up meridian limits to the same side of the pier.

Here is a short video where I show how to do this:

Now that I've gotten my pointing issue fixed (thank you for that), I want to try starting CW up tonight, and M104 is an
ideal candidate for this from my location. I do have a question about it. With meridian limits mapped out and
enabled, there are two possible ways to point at many places in the sky - counterweight down or counterweight up.

If I set up the dome/shutter for a clear shot in that configuration, can I do a Plate Solve and Recal (using that button)
at zenith , bring back the dome to the original position (180 degree swing), and then run the full modeling WITHOUT
checking the Recal Near Zenith at Start option? I assume that would be equivalent since I've just done a recal at
that point.
Yes, that would work.

Re: APPM Attempt Failed - Clearly I am doing something wrong #APCC #Mach2GTO

Ray Gralak
 

I don't see how I can change camera settings (cooler, binning) directly through APPM.
Marty, you can set binning on APPM's "Camera Settings" tab. However, you should setup other properties, like cooling temperature, in the manufacturer's camera control application or a third-party camera control. That being said, most of the new CMOS sensors are so clean that cooling the camera is not actually necessary for the purpose of plate-solving.

Thanks. This is my first attempt at platesolving with any camera. Still learning.

I don't see how I can change camera settings (cooler, binning) directly through APPM. So I assume the right way to
do this is to run (in my case) SG Pro, edit the camera settings there, and connect in APPM to SG Pro.


Re: APPM Attempt Failed - Clearly I am doing something wrong #APCC #Mach2GTO

Hi Marty,

As for #3 (Recal Near Zenith at Start) my dome shutter configuration made that difficult so I gave up on that. The
telescope is on the same side of the mount as the unopened part of the shutter. So even though the shutter is open
past zenith it still blocks about 1/2 of image. If I rotate the dome 180 degrees it would work.
Oh, okay, then you are right to disable "Recal Near Zenith at Start".

Thanks, Ray. This is very helpful.

I am getting big images (17MB) but I did check 1/2 subframe and Auto Dark Subtract was unchecked. The
computer itself is very fast (6-core Xeon processor at 2.7GHz) but I'll add time for the solution set.

I'm surprised at the need for the USNO A2.0 (I do have it downloaded) given the optical configuration and thought
the GSC11 would be enough. But I'll try USNO A2.0 tonight.
