Re: Does Howard's email at astro-physic actually work?

Have you given AP a call? You won’t find better Customer Service then at AP. You may find that with conditions these days a bit different but they are very responsive and there is George as well. Just saying.

Hi
I did discuss this on this group as well as on the pempro site and was told I have to connect Howard.
Contacted twice and have heard nothing yet.
So is this how AP operates these days? Support on forums and that's it? What if they have no answers and AP doesn't have support personel available?
I spent considerable money on an upgrade to a CP4 and since it's an older mount it seems I cannot get support.
So why say the CP4 works with all the goto mounts? If I would have know this up front all the better. I wouldn't have bought it.

Re: Strange behavior doing center here SGP and APCC/Meridian Zones #APCC

Michael 'Mikey' Mangieri
 
Edited

I am using a pointing model.  Just a few minutes ago I ran a quick slew and reslew to see if I could recreate the problem.  Here is what I did:
1) From the Park 4 position, powered up and slewed to Jupiter
2) Mount correctly determined I was in the safe zone and slewed on the east side, CW up. Jupiter was centered.
3) I then commanded a new slew without any other changes - I use Stellarium Scope and Stellarium.  What I mean here is that I have selected Jupiter (which is already centered) and requested a slew.
4) The mount now decides to flip and acquire Jupiter with CW down (west side).

This can be recreated.  I've done it twice this evening.

I've attached both the SGP log and the APCC log links as well as the Meridian tab pic:

I contacted MainSequence Software (SGP) and Jared had the following to say about the issue:

If your Sync Behavior is set to “Sync” in SGP, then the coordinates are not “new”, but the same ones we just sent the mount as that is where we actually want it to go. I don’t really understand the “Safe Zone” or how it’s implemented here. But it seems odd that asking the mount to slew to the same location would result in different behavior.

Jared


I have verfied that 'Sync' is set.

Recommendation for CP4 firmware update for remote telescopes

david w pearson
 

I have a remote AP 1200 mount with CP4, version 11, connected to the computer by serial and ethernet.
I use the serial connection to communicate with mount during my sessions.
I tried to update APCC Pro 1.8.0.9 to a later version and it told me that i needed firmware 14 to be compatible.
the CP4 firmware update document says to use ethernet to load firmware and to disconnect all other cables to cp4.
can i have problems that can't be recovered if i leave the serial cable connected while firmware is updating.  meaning if there is a problem while loading firmware that i can just keep repeating the firmware load until works or I basically may have only one shot to make it work?
What do all the other remote users do;    wait until a maintenance cycle or update with one additional cable between CP4 and computer?
thanks
dave


Re: Mach1 play in RA Axis - did not adjust out with Gear Mesh adjustment

John Davis
 

Wanted to circle back and provide some closure on this thread, so that if anyone comes on it searching for something similar - they will see the resolution of the issue.

The last 2 nights I was able to get out and image with this new-to-me Mach1 - still with the very slight play in the RA axis.

The conditions were clear, average seeing, below average transparency.  I had a 4 1/2 hour session the 1st night and a 4 hour session the 2nd evening. The first evening my PHD guiding averaged about .43" rms and the 2nd evening about .53" rms.  Both very good by standards of my previous mount.  There were one or two small glitches over the night - but I do not thing they were related to any play in the RA axies.  There were some fast moving small clouds moving through on the 1st night and that may explain the glitches.

So I do not think there is any issue in this mount despite the tiny bit of play that remains.

Thanks so much to Roland and others who helped me troubleshoot this issue!

Along these lines of the "low temp" encoder...   Is there any disadvantage to the low-temp encoder?   (other than the additional cost?)

Thanks Sébastien,

The reason I asked was I have ordered a Mach 2 through a dealer and the dealer had told me when I placed the order that the standard encoder was good to -20C, which would probably work for me (I guess I'm a bit of a wimp), but I did see on the Renishaw website that the Standard encoder has an operating range of 0C to +80C.  I have sent an email to my dealer asking if I could change my order to the Low Temp version.

Re: Satellite Tracking

Dean Jacobsen
 

David, I do all of my slewing to targets with TheSkyX Pro connected through the AP ASCOM driver's virtual ports while running APCC.  It works great.  No problems there.

I will check out what TheSkyX has to offer.  The AP Horizons program that is included with the APCC Pro bundle provided with the Mach2 looks to be a nice way to go too.  I just haven't been out to the observatory to try it out yet.

Re: Satellite Tracking

Just to be clear, I am running SkyX Pro, I don’t know what the other versions can do. In the Pro version, you can go to Input: Satellite: Import from Web: Amateur Radio Satellites.

I have a Mach2 on order. The SkyX can connect directly to a Mach 1, so I don’t know if it can connect directly to a Mach2, or if it can, how robust the connection is.

Thanks David.  I run TheSkyX through ASCOM so I will check it out.  I am primarily interested in amateur radio comms satellites and using the Mach2 as a tracking platform, so I will investigate what I can do with TheSkyX.

SkyX will download any satellite you want (the easiest way is the download of the 100 brightest satellites). You can then track the satellite with your mount. SkyX has a direct AP connection or you can go through ASCOM.

I will take a look at my copy of TheSkyX.  Maybe I can use it to at least track track the satellites that it has its database.

I don’t believe the site gives you the TLE/Keplerian data. I use SkyX. In it you can download satellite elements and then use it to track the satellite across the sky.

Thanks David, that is a nice resource.  I like the "pass details" map that it gives you.

Do you know if the site also gives you TLE/Keplerian element data for the satellites that they track?  I haven't found it yet in their satellite database.

I have also found this site: https://www.n2yo.com/?s=25544

The website heavens-above.com. will tell you when the ISS (as well as many other satellites) will be observable from your location and will even plot its path across the sky for your location. Try it out, it is a nifty site.

It was probably six or seven years ago, but I once tried using Horizons to track a comet with my Mach1GTO.  Yes, I could track the comet.  But the resulting images weren't tracked precisely enough for my taste.  There wasn't anything that I would want to send to S&T or Astronomy.  I wish you better success than what I experienced, Dean.


Re: Satellite Tracking

Dean Jacobsen
 

Hi Ed, the directions in the AP Horizons manual are excellent so I think I am set to go.  I am going to try and get a video of an ISS pass just to see if I can put all of the parts together correctly.  The ISS is listed in the JPL Horizons target list and I will find a time wen I get a favorable pass.
