Re: APPM plate solve failure and then APCC stopping working

jypeng@...
 

Hi Ray,
Thank you for pointing out the ASCOM version. So, ZWO screws up us.
I followed the ZWO install driver web page's instructions two weeks ago, Now ZWO wants their customer to rollback to SP6.4 SP1.
I rollbacked the ASCOM to SP6.4, and restarted APCC pro. The data showing the Pointing Model are looking fine now. 
However, I did see an error message pop up a few times during the APCC pro startup. "Precess.J2000ToNow: Error...." See attached images.
It seems to me that ASCOM 6.5 having Precess.J200oToNow compatible issues.
I will re-run the pointing model when the sky is clear.

Thanks,
Jian Yuan Peng

On APCC's rate settings tab you can enter a custom tracking rate which the mount will continue to use until you change it or stop tracking.

Re: Going Unguided With a Long FL Scope?

I have been able to un-guided at least up to 15m with the following.  I have not gone beyond that...do not expect to need to.

A-P 1100 / CP4  (non-AE, no HC)
APCC Pro / SGP / APPM Pointing and Tracking models (150 points)
14.5" AGOptical Corrected Dall-Kirkham...f.l. = 2500
Canon 6D full frame (Image scale = 0.55"/pxl)

Median Eccentricity (using PixInsight) across one image was 0.4552 - guided and 0.4921 - unguided
Median FWHM = 5.1 - guided and 7.4 - unguided

It took effort to move up the learning curve on the software.  Getting a good PE curve was also important.

Re: Last night tracking with Mach2

Dean Jacobsen
 

Roland, you are doing this modeled tracking with the keypad application, right?

So if the path of my object will cause my scope to hit my pier a half an hour or an hour after the meridian, I could set up a modeled tracking run up to and maybe slightly past the meridian, then when the mount tracks across the meridian I could take a few more minutes and set up another run for the object's movement into the west.  Correct?

A shot in the dark here.

I see that the screenshot with big values is at RA Rate=0 and Dec Rate = 0.   Can't tell if tracking was at sidereal or a custom rate, but it would not matter since the delta rates are both zero.  However, the screenshot with reasonable values is at a custom tracking rate

Last night tracking with Mach2

Roland Christen
 

Hi Astronuts,

I was busy yesterday testing mount software in our AP observatory. After dusk I noticed the sky was very dark - very low humidity, and good seeing. So I captured a number of unguided images of the Ring Nebula just for fun. 160 EDF refractor on the Mach2. Below is what I consider a successful imaging session.

For those needing an explanation of the pix below, I modeled a path for the object by measuring the position of 4 stars along the path. Took about 1 - 2 minutes per star to center them and add it to the model in the CP controller. The image shows how the RA axis moved over a 1 hour time period, starting when the object was approximately 3 hours from the meridian. This motion of the RA axis is a very close match to how the object actually moved across the sky. The difference or error in that 1 hour exposure was approximately 2 pixels. I took a number of 600 second exposures during that time with results as you can see in the image below.

What would have been the difference between modeled tracking with the Mach2 versus guiding? The main difference is in the smoothness of the tracking. Guiding would almost always impart a back and forth sawtooth motion, which can be very small on a premium mount, but can be several arc sec P-P on a lesser one. With fast optics and modern astrocameras, it's getting so that 10 minute exposures are plenty for even the faintest stuff. And for that you can model with a minimum of points along the object path.

Re: APPM plate solve failure and then APCC stopping working

Ray Gralak
 

Jian,

All of the solved RA and Dec positions in your screen shot are almost the same which I don't see how that could happen unless the PNT file is corrupted or has been edited. When I load your PNT file I get the attached screen shot.

Which version of Windows are you using? Also, it looks like you may be using a beta version of the ASCOM platform?

0000029 2020-06-10 21:16:58.635: Info, ASCOM Version, Major version: 6
0000030 2020-06-10 21:16:58.635: Info, ASCOM Version, Minor version: 5

I doubt this is the problem but you should back off to ASCOM SP6.4 SP1.

Re: help with AP900 guiding via ASIAir Pro

Roland Christen
 


Therefore the guiding graph shows DEC and RA just running away off the guide chart.
My first thought is that the guide directions that the mount is receiving are opposite to what is needed. The calibration is backwards. In other words, when the mount is slowly drifting North, it should receive a South move command. Instead it is receiving a North move command, which causes the drift to increase rather than decrease. I'm unfamiliar with ASIAir, but in any other guider program you can reverse the move commands if they are going in the wrong direction.

Hi,
I recently purchased a used AP900 (Goto2 panel, with upgraded Goto4 handset chip) and have it up and running and  linked to an ASIAir Pro.   Everything is functioning well (Polar Align, Plate solving, slewing, gotos are accurate..) EXCEPT for guiding..
I can't seem to get the mount to respond to the guide commands...you can see the pulses being sent to the mount but no guide corrections are being seen and the DEC and RA run away quickly.  Actually it seems that turning on the guiding routine from the ASIAir turns off the AP900 tracking altogether and I have to reset the tracking from the AP900 handset after stopping the ASIAir guiding function.  Therefore the guiding graph shows DEC and RA just running away off the guide chart.
Very strange..
I have the ASIAir connected to the COMM port on the AP900 via a USB - RS232 cable.  Just a dumb cable; doesn't have the active USB-RS232 module in it...does that matter?
The hand controller is set to "EXT" computer control.  Not sure if there are any other AP900 config settings that I should be employing...
 
Any thoughts or hints?
 
thanks...

I recommend that you seriously consider a separate guide scope, and do everything you can to minimize flexure.

I use a 300mm f/5 guide scope with ST-402 camera on a dovetail plate adjacent to my 30mm f/7 OTA. Initially I experienced some flexure, but got it under control. This link: <http://astronomy.mdodd.com/flexure.html#FlexureTable> describes what I did.

And this image: <http://astronomy.mdodd.com/flexure.html#GoodNews> is a 30-minute guided image that exhibits no flexure. I'm very pleased that my efforts paid off.

* a new camera with minimal backfocus (the ML16200 I'm using eats up
21mm - maybe the ASI6200??)
Will your C11 fully illuminate the full-frame sensor in the ASI6200? I definitely would confirm that before investing in a new camera.
