It looks like it would place the eyepiece upside down if you mounted on the left.


Possible to install the RAPAS + RAPM2 on the left side of the #Mach2GTO RA axis ? #Mach2GTO

Seb@stro
 

Hello everyone,

I was watching Tony's (aka Harley Davidson) latest and much useful videos about his new Mach2 (lucky guy, mine is scheduled for delivery in January) and one of them (ref. https://www.youtube.com/watch?v=d-Ltoqabn8k) made me wonder if it was possible to install the RAPAS+RAPM2 on the left side of the RA axis with the same adapter or say a left-sided version of the RAPM2.

I would find it more practical and comfortable to use my right eye when polar aligning (me being right-handed as well). I therfore wouldn't have to rotate the scope 90 degrees prior to PA, saving a few seconds / minutes more while I setup (I'm mobile most of the time).

Anyway, I think it would be a nice additional feature to be able to choose which side suits you best if it isn't already possible...

CS!
Sébastien

Re: New Solvers for APPM?

Marcelo Figueroa
 

Does that mean that it will no longer be necessary to use an external program such as SGP to capture images for modeling? 
 
Not a problem for me, I use SGP with ASTAP as my imaging program and also with APPM without any problem so far. But it would be a good way to simplify things.

Going a step further, given that NINA is open source the thought occurred to me to cobble something together for NINA.

Hey, a NINA dev here :)

I've considered the same - just making a wrapper program that listens on the SGPro API server TCP port and speaks the commands needed to solve an image via ASTAP (or other solver). This plus ASCOM Camera in APPM itself would decouple APPM from requiring a large surrogate app like SGPro or TSX (which is what I've been using to build models).

Users of 10um mounts are in a similar situation, only their modeling program can call ASTAP directly, it does not talk to cameras in any way - it also relies on having SGPro available to it to operate a camera. One NINA dev has such a mount and he has implemented a subset of the SGPro API in NINA to service this purpose. I am in the process of adding the API endpoints that APPM needs (the solving parts) to it. But....

But with Ray's announcement here that direct ASTAP support will be in the next major release of APPM, that makes APPM a self-suffiicient app that doesn't rely on "heavy" external software to do any part of its imaging or solving, and we can now just have APPM and ASTAP installed, and that's it! Good news. Not sure if this means I'll finish my SGPro endpoint work or not, as the NINA devs are unanimous in that we would rather put such API energies into our own design.

Well, I see that 5 minutes after I posted this that Ray says ASTAP will be supported in the next version of APPM.  So I guess for all practical purposes my question is moot.

Although I do think it would be nice for ASCOM to eventually have a plate solving interface.

Re: Meridian management

Dale Ghent
 

Hi Kevin,

As others have pointed out, you manage this by specifying a slightly wider "window" of flip time in your sequencing app so that it orchestrates the flip prior to the driver's programmed limits being hit and it either stop tracking or initiating another response, usually one that is incompatible with your imaging ;) In this case, you can think of the driver being a safety stop for your mount - if the sequencer fails to do the flip for some reason, the driver will force it when the mount sails into its limits there.

Amongst the NINA devs, we have been toying around lately with the idea of meridian and horizon limits, a la what you would find in APCC. I think this kind of tight integration between mount driver and sequencing app is important. In the case of horizon limits, it would allow the sequencer to manage a "gappy" session for a target. This is useful in the cases where the target might be obstructed temporarily by a tall tree or other object and guiding and imaging must be suspended while the object is occluded, or if you want to image something up from or down to the horizon, but the horizon line at your site is very irregular. In the case of meridian limits, the app would be able to optimize exposure times around the meridian based on the clearance map that was specified, allowing a flip to be done within a varying window of space rather than a hard set limit no matter which orientation the OTA is in.

This is all in the conceptual phase at the moment, but once a design is settled on, I would like to be able to get APCC hooked into that, via published API or other means. We'll see what the future brings once we all figure it out :)

I now have my Mach2 humming along pretty well. I have set up APPC Pro with horizons and meridians and a pointing and tracking model. Where I am stuck is with meridian behavior. I know that my mount can handle tracking past the meridian up to a point depending on where it is relative to my safety limits. My question is, with NINA or even SGPro, I have to tell the software, how long past the meridian to wait to flip so how do I predict this based on the Dec position of object I am imaging? Am I overthinking this? Should I just pick a relatively safe time, like 45 minutes, and flip there for all objects? TIA

APPM Plate Solving Alternatives (again)

Xentex
 

I have read the prior threads and believe I understand the state of affairs with APPM and ASTAP (i.e., still in the exploratory stages).

I expect a Mach2 in my hands this month and the plate solving approach that seems to make the most sense to me is SGPro (using ASTAP).  I already use ASTAP (mostly through NINA) for my existing plate solving and am very comfortable with it.  It's already on my imaging PC.  (I don't recall ever having a plate solve fail that wasn't truly unsolvable because of clouds, etc.)

After installing SG Pro and looking at it a bit I see that SGPro uses a REST interface for the API.  It also appears to be documented pretty well.  But I don't know whether 1) this is the only API SG Pro offers, and 2) if that's how APPM is communicating with SG Pro to do the plate solves.

That made me think, if the REST API is how APPM is doing plate solves through SG Pro, I don't actually need SG Pro.  I can just create a REST wrapper for ASTAP that uses the same protocol (which SG Pro documents well enough).

Has anyone else ever looked down this path?

Going a step further, given that NINA is open source the thought occurred to me to cobble something together for NINA.  That might be more trouble than it's worth since my understanding is I'd probably have no other reason to run APPM and NINA at the same time.  But to the extent anyone else wanted to benefit from this approach, they wouldn't have to install a separate wrapper written by some random dude on the internet.

My goal is less about about the money than the unnecessary complexity of using SG Pro as nothing but a simple wrapper to ASTAP.

PS:  I don't expect any kind of APPM or AP support for this approach.  The idea is that APPM wouldn't know the difference.  It would look exactly the same to APPM. I think that's the value of using REST APIs.  But if there's a reason it won't work (like APPM isn't using the REST API) then that would be helpful to know.  By the same token, if APPM doesn't have to know what's on the other side of the REST interface then any imaging program (NINA, Voyager, APT...) could add APPM compatibility.  Dare to dream, maybe an ASCOM module some day (since I understand ASCOM supports REST).
