Hi Ron,

The horizon data that is currently in use is saved in the AP Settings file but you can export it from the Horizon's tab by clicking the Edit tab.

Can't access GTOCP4 again ?

Ron Kramer
 

Every so often the new CP$ seems to check out.  I no longer see it on my routers "connected devices" listing and I also can't seem to connect to it's IP,  or it's Ethernet connection. I've powered it down and up - and no change. I had this a few weeks ago and - it came back somehow with tinkering around. well it's gone again and a day of tinkering hasn't found anything. 


My sky safari use to connect quickly to  192.168.1.13  (and no longer does).

I suspect there is no way to enter a IP to get back inside to see the setup?


Then that means connect a ethernet cable (I believe one is plugged into the new Nuc) but looking in the manual, I can't seem to find a IP that works. 


ACPP (clicking the  FIND GTOCP4  ( IP/mac address etc) feature reveals nothing. 


Also the manual speaks of a WIFI POLL untility. (link doesn't work) or asks for a pw?

And mention of a java util - with same problem.


I suspect this poll util will help me find what's in the dome...  and help out.  please advise how to get back into the CP4 so I can confirm it's setup is the same. 


I not see a GTO network listed - so I suspect it's still in client mode.  What is the default ethernet IP address that allows access? 


 172.31.0.1 doesn't work, but I think that's only in server mode.  How can I get back into it?


I see this:


Ethernet Port The GTOCP4 introduces Ethernet connectivity to the Astro-Physics GTO Servo System. The interface is the standard RJ45-8 receptacle for Cat 5 and higher cables. Ethernet (LAN) can be point-to-point (aka. peer-to-peer) with a computer, or networked without user configuration. Simply enter the IP address into the browser URL and gain access to the GTOCP4 Web interface. An IP address takes the form: xxx.xxx.xxx.xxx where xxx is a value between 0 and 255. A typical IP address on your home network might be 192.168.0.101 


Problem is - the example IP is just an example.  What is the actual IP?

Hello All,

Is there a recommended interval to regrease AP mounts or it’s based on conditions? I would not expect less than 5 or 8 years unless the mount is frequently exposed to moisture, dust, etc.

Re: APCC + SkySafari?

SkySafari 6 pro was just released a few minutes ago.  Special intro price 19.95 - I've been beta testing it for the past several weeks. (months?) 
ODDLY - today I could not connect SS to the mount.  I'm a gluten for trouble. All was well, but I picked up a intel Nuc and have to reinstall all software
and drivers over to that machine. (Which I will leave in the dome even in these sub zero winter months). Having trouble connecting to the CP4
wifi at all as of today.

Hi Hemant,

Although that's one way to do this, there are a couple other ways that have been planned to handle this:

1) We will embed in APCC a server that SkySafari can directly connect via wifi as if it were the mount.
2) We will provide a ReST API to allow other applications to connect and use APCC.

I expect these features to be available by the end of this year if nothing major comes up to affect progress.

NGC 247 – Interesting void within an intermediate spiral Galaxy


NGC 247 is an intermediate spiral Galaxy located in the constellation Cetus. It is a member of the sculptor group and is located approximately 11.1 million light years away. The most striking feature of this Galaxy, the void, contain stars that are different from those around. They are older, redder and colour, and much fainter. This suggests that the star formation within the void has been arrested. It is believed that star formation slowed a billion years ago.  We are still unsure how the void has formed.  Recent studies suggest it might have been caused by gravitational interactions with another galaxy, or even a recent interaction with a nearly dark subhalo that collided with the disc. 


The centre of the Galaxy is visible as a bright whitish patch surrounded by mixture of stars, gas, and dust.  Silhouetted against the background of stars the dust and gas has formed interesting filaments.


The best month for viewing NGC 247 is in November when it is at its highest altitude.  It has an apparent magnitude of 9.9, and an apparent size of 21'.4 × 6'.9.  NGC247 is also known as ESO 540-22, C 62, IRAS 00446-2101, MCG -4-3-5, PGC 2758, UGCA 11.

Re: Guiding Issues with Mach1 GTO

Rolando -
Thanks.  I will follow your steps down to the letter on the next clear night.  Thank you for taking the time to provide all that information.  I will update my results.  Thanks again.

Tom


Re: Guiding Issues with Mach1 GTO

Roland Christen
 

This is what I would suggest for anyone who just got a new mount, whether it is an AP or any other brand. Do a simple analysis as outlined below so that you know what you are starting with:

First pointer is to turn off all backlash compensation in PHD. Then set your guide speed to 1x. Next is to get a good accurate calibration at the celestial equator near the meridian.

Polar alignment is desirable so that Dec does not drift more than about 1 arc sec in 5 minutes. If uncertain about polar alignment, turn guiding off initially and watch the drift in Dec on a star near the zenith. Adjust the azimuth until you get no drift of the Dec axis (best done near the celestial equator, but works at the zenith also). This also will give you a baseline error component due to seeing that will be the minimum level that you can expect to achieve during guiding. Watch the guide star as it slowly drifts away from the Dec line and turn guiding on with aggressiveness set to the absolute minimum at first. Increase aggressiveness slowly until the star moves to the zero line, but don't go any further. You want stability rather than setting it to 100% and hoping for the best. It will probably head towards the zero line at between 50 and 70% aggressiveness.

Next turn off RA guiding and watch the graph for about 6 - 7 minutes with PEM off, and let the guide star drift up and down and take an image of the result. The peak to peak should be under 10 arc sec and could be below 5. If you have any drift in RA, you would need to subtract this from the peak-peak drift of the periodic error to get a good idea of how well the worm gear is tracking. Of course it would be nice to have no overall drift, which could be achieved with proper altitude alignment (polar RA drift align).

Once you have the baseline RA tracking error curve, turn PEM on. Do the same test again, this time with the RA axis. Since this is a used mount, it could very well have a totally hosed up bogus curve in it, courtesy of a previous user who did not know what he was doing. So, if the PE data is good, the result will be a better tracking graph than the PEM-off data. If it is not better or is very much worse, then you have two choices: 1) use the mount with PEM set off, or 2) create a new PE curve, load it in and run the mount with PEM on.

The above steps will allow you to characterize the mount and give you all the information you need to determine how well your mount actually works and will allow you to make good settings to your guider program. You will also be able to communicate this info to others in the user groups to help determine what may be preventing the mount from guiding accurately. Just showing a guider graph is not helpful without a complete understanding of the mount's actions.

Rolando

Subject: [ap-gto] Guiding Issues with Mach1 GTO



Hi.  I have recently (2 months ago) purchased a Mach1 GTO that was made in 2007.  This mount was basically unused in all that time and sat in the gentleman's closet for 10 years.  It looks to be in great condition and sounds perfect.  I have it mounted on a pier in my observatory and am confident of excellent polar alignment.

That is all the good news.  The bad news is that I cannot get consistently good guiding no matter what I try.  I have tried with a guidescope and an OAG, I have tried with PEM turned on and off, and I have been very specific about my settings in PhD2 (never had problems using it before).  Nothing seems to help and I'm sure this mount is supposed to provide very accurate guiding.  I am going to attempt to attach a picture of my guiding results from the other night as example.  Any help or pointers would be greatly appreciated.

Thanks,
Tom
