Yes indeed, most L filters filter ou UV and IR. See some measurements here :

RGB filters automatically block all UV, so adding another doesn't do anything. Secondly, adding any flat piece of glass before any filter will set up multiple reflections between the two glass surfaces which will result in multiple faint halos that are not centered on the star, and will probably show up nicely around every bright star. It's like being in a hall of mirrors and seeing yourself multiple times off into infinity.

I recall reading somewhere (maybe Ron Wodaski's book  "The New CCD Astronomy") that some imagers have a common UV-IR filter in their imaging train so that even when they are imaging through the Red, Green, or Blue filters, they are also filtering with the UV-IR to block out light pollution. Is there anyone doing this ?

Re: Satellite Tracking

Welcome to the group Brent. 

I will definitely be following your progress on your satellite tracking interface.

The software bundle that comes with the Mach2 contains a program called Astro-Physics Horizons.  If you haven't seen it yet, here is a link to Ray's help files for APCC and the Horizons program is at the bottom of the table of contents.

https://www.siriusimaging.com/Help/APCC/index.html

I haven't yet actually attempted any tracking with the AP Horizons program yet.  I have been just doing manual tracking of the handful of FM AMSATS that my FM UHF/VHF radios allow me to contact.  I need to upgrade my radios to be SSB capable on the UHF and VHF bands that the AMSATS with linear transponders operate.  However, based on my manual tracking, I am convinced that the Mach2 is plenty fast to track the satellites that I am interested in.

Anyway, I hope to be able to at least try out the AP Horizons program on a favorable ISS pass and video the pass this next new moon cycle when I am set up out at our club's dark sky site.

Yes, I guess the tricky part would be at the point that the object passes the meridian and dealing with a mount flip.  However, passes for my objects are frequently on one side of the meridian for most of the pass.  So I guess I will find out how that detail is handled in the AP Horizons program.  :-)

I just joined the group tonight and came across this thread.  I am the original author of the satellite tracking program and the "resurrected" software that Robert spoke of.  I recently joined the wait list to purchase the new Mach2 and intend to develop a specific interface for it for satellite tracking.  1000x sidereal is fast enough for the majority of passes, so no problem there.  The Mach2's ability to slew well past the meridian is a huge advantage as the satellite's closest range is usually near the meridian and it is frustrating when tracking ISS at its closest point and the mount does a flip. Very few mounts support variable rate tracking through ASCOM so at this point I am only doing "leap frog" style of tracking with ASCOM. (Celestron and some Meade mounts are able to continuous tracking through a "legacy" interface using their command language but not their ASCOM drivers). I look forward to when I get my new AP mount as without a doubt it will be a great mount for satellite tracking.


Re: How does one perform a factory reset of APCC.?

Ok, then what is your question?
Did the screen shot of the Driver Setup help?
The ASCOM Driver can initialize the mount all by itself in the simplest possible setup. Is this not clear?

Rolando, 

       This seems to answer one of two questions I have about the initialization  process.  the settings from APCC are loaded into the controller at the time of startup initialization and are not persistant within the controller.

You can set things up either super easy or super complex, depending on what you want to accomplish. Before adding complexity I would first set things up with just a planetarium program and use that to slew around the sky and get familiar with the way the mount points and tracks. Bring up the AP ASCOM Driver Setup as shown below and uncheck APCC Virtual Port. Then just bring up SkyX, and connect to the mount. The ASCOM window will come up and show tracking at sidereal, and you are good to go. Now simply click on an object, press Slew and the mount will go there. It's so easy, I can get a duck off the street to do it.

(In fact, you don't even have to first connect SkyX to the mount - if you simply click on an object and press Slew, SkyX will automatically connect itself to the mount via the ASCOM Driver, and then proceed to slew to the object)

Once you have mastered this very basic setup, you can go back into the ASCOM Driver setup, re-check the APCC Virtual Port and begin using APCC to do more complex control functions. BUT please read the instructions first!

I received my new Mach2 GTO, and while exploring APCC I have somehow gotten my mount unable to slew to the East of the Meridian nor south of the Celestial Equator.

So much for imaging  Mars tonight.

Is there a full factory reset for APCC? on the GTO CP5 controller?

Any assistance will be appreciated.

Without APCC running, you could rename or delete the settings file located here:

C:\ProgramData\Astro-Physics\APCC\Settings.apcc

But, before you do that, you should try homing the mount. On the AE tab in APCC Pro, you can click "Find Home", which will slew the mount to the home position (Park 3 position) and sync the mount to that position.

Also, please make sure to install the latest version of APCC, which you can download from here:

Hi All,

Not a "go-to" question. Looking to see if anyone by any chance has (and is willing to sell) or can point me to where I can find a field flattener compatible with an Astro-physics 130mm F6 EDF (780mm focal length scope). AP do not sell them anymore.

Thanks
