Hi Dale,

Thanks for the log files! It looks like the problem was that the site name that was selected was not found in the driver's site
database so it could not lookup a latitude/longitude value to set.

That was just what I found with a quick scan of the logs. If you think that should not have happened I will look a little deeper to
see if I can figure out the specific site name it was trying to find.
It shouldn't have happened, as I configure the driver's list of sites via the Setup Telescope tool and was just using this very same site (labeled "HALO") just moments before, prior to this kerfuffle. You'll see it specified in the driver screenshot I linked in my earlier post. Strange.

Underneath the hood, does the Setup Telescope tool write out to an intermediary settings database (ini file, or other?) that the ASCOM driver then reads from and sends the appropriate commands to the mount upon it starting up? Could this file have been corrupted in some manner, perhaps?

Thanks for taking a look at this, though. I haven't been back out since that evening so I have no idea if the problem will persist, but your explanation does shed light on why programming the location with the keypad worked when doing it via the driver didn't.

Re: Pelican with 130GTX

Roland Christen
 

Hi Guys,

While testing mounts in the observatory i get a chance to image, but because of severe light pollution most of my imaging is narrowband. The Pelican is up there nicely and I can get a few shots every evening. Although my night sky is not mountain-top quality and seeing is rarely better than 2 arc sec, notice the resolution of the 130 GTX at its native focal length (a bit longer at F6.6 with the field flattener).

I see lots of images posted with those 100mm F5 scopes imported from Japan, China etc, but to me they all lack resolution. Sure wide field is fine but sometimes we get so carried away (like when using 60mm short astrographs) that we really never reach what the skies can really give us. For me, the 2 arc sec threshold allows an almost perfect match with the 130 F6.6 focal length. And that is not the lower limit, since I have gotten 1.5 arc sec on rare nights when the sky is just pristine and nothing moves. By the way, this image is just a small portion of the full size, which I will post at some point when I get a few more subs together. All the subs are 30 minutes long, some guided, some unguided.

For the guided images all are under 0.2 arc sec rms. Some of these subs were take unguided and the tracking is around 0.5 arc sec rms, mostly due to very slow drift in RA and Dec. I did not use any modeling, just zeroed out the drift with alt and az adjustment and that worked just fine for this object for an area of 4 hours centered around the zenith. I am using both Mach1 and 1100 mount for this testing.

Re: APCC Questions

Ron Kramer
 

I use SGP. It flips at the meridian and does a plate solve before and after to make sure it's still centered on the target. 
It the meridian is 9 minutes away and the next exposure is 10 minutes long. It will pause the exposure and wait for the flip before it proceeds with the next exposure.  Happens every night without error. 
When or how long past the meridian would have to do with your rig and mount. (when if the camera end makes contact with the tripod or mount). That will vary from setup to setup. 

How long will the Mach1 track past the meridian before it will do a flip?  Last night, as I was packing up, I thought I would just track a star and watch a meridian flip. (Never let my previous mount do this.)  The star crossed the meridian and I let it go for nearly 25 minutes.  The Pier Side indicator changed to CwUP, and it kept on tracking.  After 25 minutes, I needed to get to bed, so I stopped the mount and did a park.  No flip.

In that regard, I agree that the AP V2 driver documentation and user feedback should be more clear. The only
place that you can
change Lat/Long is in the AP V2 setup dialog, which is usually run when the driver is not connected. And in the
help section for
"Initialization Setup" it states that most of the options (including "Set Latitude/Longitude") apply only when the
mount is
initialized. I think a more straight forward statement there is needed.

https://www.siriusimaging.com/apdriver/help/initialization_setup.htm
Yeah it essentially says that, but it could be clearer for sure.

However your thought about applying Lat/Long from a "known" parked position may be possible. I will talk this
over with Howard to
see if there is a "safe" way that this can be done.
If you two could make that happen, it would certainly push me (at least) over the edge on making the CP3 (Rev
O) -> CP4 jump. Due to living under a light dome and having poor sight lines to the sky around my house, I'm
stuck having to be mobile for any viewing/imaging except for solar. Between the different club sites or places I go
camping, any improvement in flexibility and ease regarding Location setup would be a big deal.

The subject must have released the gremlins, as just this past weekend I spent an hour trying to figure out a
location issue that my CP3/Mach1 started experiencing after I had to switch batteries, which of course meant the
mount had to be powered down momentarily. When I brought the CP3 back online with the new battery, the driver
could not change the lat/long *at all* and the mount was stuck at 0/0 for its lat/long:

http://i.imgur.com/eKA8Xqd.png

After an hour of repeatedly power-cylcing the CP3 and trying to get the driver to initialize the it with the right
lat/long for my site's preset, the problem persisted. Eventually, I gave up and dug out the hand controller, inputted
the site's lat/long into a location slot and was able to set it that way.

Thanks again for the feedback, Dale!
Thank you for looking into this!

Re: APCC Questions

mogollonobs
 

Hi Darrell,

AP mounts don't have a built-in flip. I've imaged for 8 hours straight without one if the object was far enough north or south to not cause an accident with the pier. You have to set it in your imaging software to flip sometime after crossing the meridian if you need one.

If you are visual, or manual AP for that matter, and using the keypad or another device, just re-issue the goto command to the same object after crossing meridian and the mount will change sides of the pier.

Enjoy!
Keith


Re: APCC Questions

Darrell Betts
 

Thanks.  Thats what I suspected, but wanted to make sure before I started changing things.

So just to be sure, Page 132 of the APCC-ST manual - 5.14 Meridian Tab.  I start from here and work forward.  At this point, I was not going to set any Horizon Limits.  I realise the manual suggests I do.

Will there be a problem if I do the Meridian Limits first, and later if required I do any Horizon Limits? Or have no Horizon Limits at all?   I do all my observing in a Dome and I am always there - I do no remote work.

Thanks
Darrell

Re: First light with Mach1 - a query

Roland Christen
 

Had the same thing happen at our remote observatory in Chile. The fans on the back of the CCD camera were not low vibration type and the stars were fairly large ovals even in a 1 sec exposure. As soon as we turned the fans off, the stars went perfectly round. We ended up replacing the fans with low vibe ones and problem solved.

It took me some months to achieve what I'm getting now.  Last night - It was a bit poorer, I was seeing smaller stars look like horizontal lines.. After 9 subs and much wondering - why I'd see a horizonal elongation, it HIT ME...  I forgot to turn off the dome fan. (fan used to keep condensation from forming on the mount/scope) once I turned it off I went from .55 to .35 simply due to no fan blowing on the scope.  Goes to show - how little 1 micron is. = )
