Hi Liam,

 

Oops, got it figured out. I read where TheSky X had drivers for the 1100GTO, so I didn’t select TeleAPI selection, selected com port 5 (virtual), and corrected the time on my computer to match TheSky (I had deselected DST and was thinking of going to UTC), and was able to connect. 

 

The only question now is if APCC uses comport 3, do other programs an devices like Maximum DL, cameras, and focusers, need to have their own dedicated com port (virtual)?

 

Thanks,

Don

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?

Just FYI, I used TSX with my 1100 (no encoders) for years. When I added my Mach2 (with AE of course) and set up for remote imaging I quickly learned that TSX was (1) unnecessary and (2) created a potential source of problems. My routine now is to use APCC to initialize the mount, start up SGPro to slew the telescope to the desired location (preset), then do a platesolve for final positioning and camera rotation, and then start the imaging sequence.  No need for a planetarium program.

Re: Back Focus Troubles #Absolute_Encoders

Don Anderson
 

Hello Andrew
I have been following your thread on this with interest since I went through this exercise some years ago when setting up my imaging train on my Tele Vue NP127is refractor. The concepts can be difficult to get and keep straight in ones head and it is very easy to get confused especially when adding correcting optics and allowing for filter refraction. Mike gave a very good description of how to handle correcting optics such as reducers and field flatteners that are introduced downstream of the focuser.
As you and Mike discussed, spacer tube selection is not necessarily critical when setting up for native F/L imaging or for imaging with correctors in the train as long as one has lots of back focus to work with. However, most scopes have limited back focus capacity and now a days astro-imagers are trying to cram more gear into their imaging trains. Further, scopes other than premium ones have focusers that are not as robust as one would like and can not handle even moderately heavy imaging trains without significant draw tube sag if the draw tube is racked out a significant distance. For these and even for really good focusers, it is best to limit the drawtube extension when at focus to as little as practical to minimize sag.
I have a Tele Vue NP127is refractor with the Tele Vue stock 2.4" focuser. My imaging train consists of a Starlight Xpress SXVR H-694 camera attached to an SX filter wheel. I can image at native (660mm f/l) using spacer tubes or I can image at 580mm f/l using the TV NPR1073 .8X FR using appropriate spacer tubes to meet the 55mm reducer BF spec as well as the necessary spacer tubes to bring the sensor into focus. Tele Vue recommends setting up the imaging train so that the draw tube extends out no more than 25mm at focus. I started by detersmining the scope back focus from the back of the rear lens cell (The NP127is is a Nagler-Petzval design) which for the NP127is is 278mm (10.96"). Using the rear of the lens cell as a datum, I calculated all spacer dimensions from that datum point. I made sure for all setups that I selected the spacers that would position the draw tube 12-19mm (1/2"-3/4") out from a fully racked in position when the sensor was at focus. I have attached a drawing to illustrate what I am talking about. Another setup which I have yet to try, is imaging with my 2X Powermate (1320mm F/L). This should be easy since the back focus distance behind the Powermate is pretty flexible. I just need to fit within the 10.96" overall scope back focus.
I hope this is of interest.
Regards

Update: I mentioned in my original post that I hand contacted a Telescope and Eyepiece manufacture and got two different answers to the following scenario.

 

Assume there was correcting element that moves with the focuser that requires 50mm of fixed back focus and the imaging chain had a camera and filter wheel (with no filters) with a physical length of 25mm. In this configuration a 25mm spacer would be required to achieve back focus. If a 3m thick filter that adds 1mm of back focus is installed in the filter wheel, what would be the length of the spacer needed to achieve the correct back focus?

 

One person told me 24mm, another said 26mm.

 

This discrepancy is what led me to post the question here. I am happy to report that the person who told me 24mm tracked me down today and changed their answer to 26mm. They explained that adding the filter to the optical path increased the total back focus of the system. Introducing the filter increases the total back focus of the correcting element from 50mm to 51mm. Therefore the length of the spacer required to achieve the correct back focus for this scenario would be 26mm (50mm native BF + 1mm BF from filter – 25mm physical length of other components = 26mm spacer). I have to say, I was really impressed that the company would take the effort to contact me to correct their mistake. This is a rare thing.

 

This correction helped validate my initial thinking that adding a filter that adds 1mm of back focus changes the total back focus of the system as the starting point for the spacer calculation, before subtracting the physical distance of other components in the imaging chain. It is easy to get this backwards and add the 1mm to the components that are subtracted from the native back focus of the correcting element. This is the mistake the person made who said I would need a 24mm spacer.

 

I found this explanation helpful so thought I would pass it along. It also demonstrates how easy it is to make a mistake that would lead to a 2mm error in the calculation.

 

If adapters are ordered 1 – 2mm shorter than required and shims are used to achieve the correct back focus as described in Dale’s post then this mistake is easy to correct. If adaptors are ordered to the exact calculated length as I use to do, this can be a cost mistake to correct. After talking to the person yesterday who told me 24mm, I thought I was going to have to order a bunch of new adapters because I had ordered them to exact length and if what he told me was correct, it meant that all my adapters were 2mm to long. Thankfully, it appears I might be OK if I ignore the tolerances. Ordering them shorter than needed is definitely the way I plan to go in the future.

 

I hope this was useful.

Re: Planetarium software

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

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.

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.

Re: Planetarium software

ap@CaptivePhotons.com
 

  • 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”.

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.
