Re: Ap1200 / TheSkyX jog runaway

Allen Gilchrist
 

Ray,

Thanks for taking the time to respond.  Mike summarized your message for me, and I was able to get the ASCOM driver to work this afternoon.  Unfortunately the run away after a Jog command from TSX still occurs.  I'll have to wait on a fix from Software Bisque.  In the mean time, I now have the option of using either the native AP1200 or the ASCOM methods of connecting to my mount.  A friend has recommended PHD2 for autoguiding, and there may be some advantages in using ASCOM for the mount connection with that program.

Re: 2 Pier Observatory Scenario for Mach2 x2

@mmalik
 
Edited

Thanks for the feedback; much appreciated. Actually 8 ft. square is just the wooden deck, observatory itself is 7 ft. circle made of prefabricated plastic panels (SkyShed Pod).

As far crammed space goes, I feel that should be manageable in a primarily imaging setup (...I do see the need for space for visual observing though). I don't intend to have desk or other setup in there and most of the computing will be compactly mounted on the pier/s. FYI: I don't intend to guide with Mach2, my stated goal for all imaging in future. Following is the best case scenario I have come up with so far, at least on paper. Regards

Note: There will be bit more space on the wooden deck for other activities while imaging happens in the POD


1/2 the Radius Rule (for PODs)...

What I am proposing is putting piers at about the half-way point of the radius. This probably will be the simplest and safest approach as far selecting the pier center/s goes. Rest (latitude, scope size/type/number, etc.) will have to fall into place within certain limits. Regards

Note: Of course I'll be able vert it all out once I have all pieces in hand especially Mach2

I wanted to circle back and document how this ended in case anyone has the same issue.

I set the mount and scope up, verified balance and verified that it would park at positions 1-4. Once this was done, I tried to get it to park at Alt Az, and had the same issue as before. Then I aborted the park, manually went to what I wanted Alt Az to be, commanded it to park at current position. Once parked, I set Alt Az. Now it repeatably parks at Alt Az. 

I can only assume that the last time I set Alt Az, the mount was not actually parked at that position where it needed to be.

What is the current status for Linux / Mac support via INDI or similar?

Henry Kwok
 

Although I have been using Windows / ASCOM. I am really keen to make a move to Mac/Linux. Software like CCDCiel and Ekos are maturing quickly and more importantly they are much less resource hungry and therefore can be run on low power device like a Raspberry Pi. I am particularly fond of CCDCiel and would like to make it my main imaging software. However the lack of reliable support for Astro-physics mount via INDI and Linux / Mac is preventing me from making the move completely. Specifically, the latest version of the INDI driver for AP mount appears to be problematic for some time.

Is there anyone who is using INDI in linux / Mac with an AP mount? I have a Mach 1 with a GTOCP3 box and V2 firmware, and I am from the Southern Hemisphere if it matters.

Thanks

Re: Ap1200 / TheSkyX jog runaway

After you choose ASCOM under telescope setup you have to open Settings in the Mount Setup menu and choose the AP ASCOM driver. Make sure that the correct COM port is selected and you should be all set. This needs to be done only once.

Re: 2 Pier Observatory Scenario for Mach2 x2

8 ft square looks too small for 2 setups. I have a 22ft x 12 ft roll-off roof observatory with 2 piers. Has just the right amount of space to move around in. Room for benches/tables, small cabinet for things like accessories, computer hardware, observing chair, etc.

How viable would be a 2 pier scenario in a SkyShed Pod observatory housing TWO Mahch2s. Some assumptions, payload configurations, and observatory dimensions are as follows.

Assumptions
 
  • Red lines in the diagram are the maximum/safe lengths of scopes in neutral position, not necessarily the park position but clear of dome rotation and/or dome closure
  • Green circle is the moment arm for counter weights/shaft clear of the wall insides
  • Intersection of RA/DEC axes at or couple of inches above the wall edges
  • Extreme positions of scope/s can extend beyond wall and dome demarks in a PZT (...a platform where entire top dome section can be pushed out of the way) and/or one operational scope (...at any given time) scenarios
 
Payload (... to be optimally distributed between TWO Mach2s given the tolerances diagramed below)

Desired scenario may be to load 180ED on one and StarFire+85ED on the second?

Epsilon-180ED
Clear aperture: 180mm (7")
Focal length 500mm (19.6")
Focal ratio f/2.8

Diameter 9.1" (232mm)
Weight 23.5 lbs. (10.7 kg)
 
StarFire 130mm
Clear aperture 130 mm (5.1")
Focal length 819 mm (32.2")
Focal ratio f/6.3
Length 28.5" (724mm) [Retracted]

Re: 2 Pier Observatory Scenario for Mach2 x2

While interesting, the POD internally is very small.  I found it cramped for space with my Mach 1 and FSQ, with minimal access to the sky unless you push the dome completely off.  You must account for the counterweight bar and OTA swing radius very carefully in all potential combinations.  If you are going to spend $20K on mounts and accessories, consider a new roll off roof configuration.  - jg

Re: My Mach2 first light

Roland Christen
 

I like the Apple logo on the gearbox Smile

To align the RAPAS, first you need to do a polar alignment with another application (Drift method or Polemaster). Once the mount is polar aligned, you can then align the RAPAS with the 3 push-pull screws until Polaris is placed at the proper point in the 24 hour reticle. Once you do that, you can re-create the polar alignment using just the polar scope.

Subject: [ap-gto] My Mach2 first light

Hi,

Our Mach2 arrived last December. We made a tripod adapter to put it on a TAK wood tripod, and a counterweight shaft adapter to use our existing counterweights. Now it’s ready to go.

We are having some excellent weather (which is rare) this weekend. So I took the Mach2 to a dark place. The scope that goes with it is a TAK TOA-150, and the camera is Pentax 645z. I attached two photos. One is our Mach2 with TOA-150. The other photo has two TOA-150, and ours is the one to the right. The one to the left is my friend’s TAK EM-400. The Mach2 is shorter, much more compact, and also much lighter.

Now it’s slightly passed midnight. I am continuously imaging. The Mach2 is solid, stable, trouble free, and very easy to use. I can’t say the same for our previous mount. So I am extremely happy now. 
For polar alignment, I initially tried the RAPAS. It’s very easy to use, but somehow I got a large alignment error. Later I align it again with a PoleMaster. Now PHD2 rarely needs to issue correction commands. Even when PHD2 does issue correction commands, I suspect that it’s just chasing the seeing. The tracking is very good now. And I will study why my first attempt with RAPAS failed. I really prefer using a polar scope rather than PoleMaster.
Will show you the images I take after a few days. I have one more night to go, and it will take a few days to process the images.
Cheers,
Wei-Hao

ASCOM with AP1200 GTO and TheSkyX?

Allen Gilchrist
 

I tried to post this last night, but I don't think it got through.  I have not been able to get ASCOM to work with my AP1200 GTO and TheSkyX (TSX).  I downloaded ASCOMPlatform65SP1.exe to my Windows 10 observatory computer, and installed the ASCOM platform.  Then I downloaded Astrophysics_V2_Setup_5.30.10.exe and installed the AP1200 GTO driver.  I was able to set up the mount in the setup program, and then connect to the mount with the Jog program.  I could move the mount around and test many of the functions.  When I opened TSX, and tried to connect to the mount from there, however, there was no listing of AstroPhysice GTO V2 Mount under either the ASCOM or Astro-Physics tabs.  I did find something on the web about a special driver for TheSky, but the post it was several years old, and I think the current versions of TSX should work without it.  I'm missing something.  Can anyone help?
