I use Cartes du Ciel (CdC) for GoTo.  CdC integrates well with ASCOM to A-P ASCOM Driver and APCC. 

With CdC, I use a similar process to Roland for centering elsewhere from the desired object.  Particularly handy for multiple objects, e.g. galaxy clusters.  I just pick a star at the desired center point, slew, and plate solve with local version of astrometry.net.  I write down the star ID and I can use it multiple sessions. 

CdC and AN are both free and robust

Go with George's recommendation.

The TSX ascom driver can be found on the bisque site, if you choose TSX. Use this link to download it  https://www.bisque.com/wp-content/x2standard/

I can connect with APCC to the mount with the 15 ft serial cable which came with the mount, using Serial Port 3. I think this part is working because I am able to control the mount with APCC, driving it from point to point works, and I can park it.

The problem occurs when I try to connect to the mount in TheSky.

I follow the instructions in the text box pop up during the TeleAPI driver installation.  When I get to step 6: “Again go to Mount Settings and this time choose Settings. This time the ASCOM telescope chooser will appear.” When I do this I get the pop up “A necessary driver was not found. Error =217.” When I went to the ASCOM home page to download the TeleAPI drive, it says do not use with TheSky X. It was TeleAPI v5.04 specified in the AP ASCOM instructions, but I wonder if that could be a problem?

I recently received an 1100GTO with AE,  and I am a new user.  I’m trying to figure out the best way to configure it for remote imaging, and would appreciate your help. 

Seems like you need a method to drive the scope to the desired target, then APCC Pro takes care of tracking with help from a guide scope for long exposures. 

Also, I’ve read on the forum that Roland uses TheSky X (I assume for target selection), and Maximum DL (I assume for camera , focusing, and guide scope control).  Did I read Roland’s post correctly?

I purchased TheSky X Pro, downloaded and installed the TeleAPI v5.04 driver, but have been unable to connect. Can anyone help with this issue.

Don,

 

You will not use the TeleAPI driver, as it is for an outdated version of the Sky.  

 

Go to our Software Updates page and download:

  1. FTDI driver
  2. Java
  3. ASCOM Platform
  4. AP V2 ASCOM driver

 

https://www.astro-physics.com/software-updates/

 

Do the above before plugging in the CP4.    Call me with questions.

 

Regards,

 

George

I have been using TSX on my AP1100 regularly. What is the TeleAPI v5.04 driver? I have used the Ascom driver for TSX which you can download from the bisque site. You first have to fire up APCC (if you have it) then fire up the AP1100 ascom driver authored by Ray Gralak and then you configure TSX to connect to the AP asom driver and that should do it.

Without plate solve how do you go to the same place over multiple sessions?

Re: Planetarium software

  • Just want to remind those who use MaximDL. They have an easy centering routine that I use when framing an image. Instead of doing a plate solve and centering an object, sometimes I want to frame the object away from the center for composition purposes. In MaximDL you simply point to the place in the image that you want centered (Point Here), and the mount automatically centers on that position. There may be nothing there to plate solve on, but you can center your image anywhere you want.

 

One of my favorite aspects of NINA is you can do that inside of NINA, it will load images from various internet sources (or just annotated maps if you are offline), and then you can frame on top of them, moving the center AND the rotation.  Then it has a “manual rotator” so that when it centers the mount, it will prompt you to rotate the camera by saying “turn 30 degrees clockwise” and iterate until you get it to whatever level of accuracy you want.  So not only can you get good framing from real photos (without trying to take a sub – that might not really show much detail), you can replicate the position AND rotation night after night.

 

The integration of both a planetarium (i.e. generated star maps) and actual sky survey images is awfully handy when you are trying to frame things nicely if your field of view is close to the target size (sadly I often have tiny tiny targets and a great wide field of view, but that’s another story of aperture envy 😊 ).

 

Honestly I would take the change as an opportunity to download trials of all the key contenders and experiment a bit, see what you like best.  There is no single right answer.  It’s kind of like asking “what’s the best food”.

I already use APPM for my AP1100GTO. Once I get my AP Mach2 (hopefully soon), yes, I will have two licenses then.

there are things like closed-loop slews (as TSX terms it, others just call it centering) that will fix any post-slew pointing error.

Correct me if I'm wrong, but T-Point will not give you tracking modeling when using it with a non-SB mount, correct? Point modeling doesn't really amount to much in astrophotography when there are things like closed-loop slews (as TSX terms it, others just call it centering) that will fix any post-slew pointing error. You do want tracking modeling, however, and s far as I'm aware, only APCC+APPM will give you that with A-P mounts.

I'm a contributor to NINA so it's obvious where my personal preferences lay and what my likely suggestion is going to be. But whatever you choose to use, I *highly* *highly* suggest using APCC+APPM over T-Point now that you've moved over to Astro-Physics hardware. The good news is that you ought to have two licenses for APCC Pro if you purchased your two mounts new from A-P or one of their dealers.

Re: Back Focus Troubles #Absolute_Encoders

Seb@stro
 

I always wondered what the impact would be on these systems when a Crayford focuser is used and the primary mirror is locked at a specific focus position, effectively swapping the variable and fixed portions of the optical chain. 

I too had that question on my mind for quite some time for the EdgeHDs (I own the C8). 

From my readings, my understanding at this point is that with a crayford-type focuser in the optical chain, the backfocus spacing from the last optical element still needs to be pretty accurate (to < 1 mm) to optimize the field flatness over the entire sensor area / illumination circle. 

Hence, with a crayford on these scopes, the focus point needs to be pre-set with the primary mirror focuser prior to locking the clutches and should then only be fine-tuned by the crayford (auto)focuser to microns precision. The backfocus spacing tolerance for field flatness being an order of magnitude or so greater than that of focus point, field flatness should not, in theory, be impacted (much) by the change in backfocus spacing from the crayford reaching the focus point.

But as I said, this is my understanding only. If someone has a better explanation, I'm very interested in hearing it too.

Sébastien

Re: Planetarium software

Andrea Lucchetti
 

Shailesh,
That’s quite interesting.
With the PMX you can use direct guide in skyx.
As you probably know the setting are very different from normal guiding but when done usually works very well. I used to ha e a Tec 140 with FF @1016mm, and in 10 years I’ve never had a guiding issue. But I am happy you found an alternative that works for you. Andrea 


Re: Planetarium software

Shailesh Trivedi
 

Hi Andrea,

My experience is positive for camera addon and Tpoint addon, but autoguiding is a bit hit or miss at higher focal lengths; for example when I use it with Astrodon MMOAG on my TEC 180FL at 1134mm focal length, even if I find several stars and with perfect polar alignment of my PMX on a permanent pier, the autoguiding performance was suboptimal and the star would be lost often. When I switched to PHD2, I got consistently better star shapes, with no star lost issue, and hence better overall images.

ap,

Thank you for that explanation. Using a focuser to correct or compensate for these changes makes sense in a standard SCT without any correcting elements in the light path. Moving the Primary Mirror or moving camera sensor should have the same net result.

I think this becomes more complicated when using an Edge HD system due to the glass correcting element in the baffle or adding the .07x focal reducer. 146.05mm is a very specific number. I always wondered what the impact would be on these systems when a Crayford focuser is used and the primary mirror is locked at a specific focus position, effectively swapping the variable and fixed portions of the optical chain. It is not something i necessarily need an answer to as I no longer own and Edge HD, but just curious.
