Awk! I can't type any more, and apparently I can't proofread either. The diminished typing ability is due to a 2007 stroke, so I usually proofread things three times to compensate. Missed big-time today!

My guide scope is 60mm aperture @ f/5, and the imaging scope is 130mm @ f/7.

Thanks for the heads-up.

Re: APCC and APPM - just wow

 

wrapping up first light, I apologize for the rather terrible reflections and total lack of any calibration frames, but for 20 mins of lum integration (@ 60 sec/image) and the crazy polar misalignment (due to lack of tech ops time at the site) i have to once again say APPM is pretty magical for correcting this, and super easy as a first time user


now we just need to hunt down those reflections (any ideas anyone?)

Just for laughs I auto-ran APPM "small" model to see if I could correct that, hoping maybe we could pull a first light that had at least sort of round stars and not just a smear. Never used that part of the program before, but 20 minutes later, it successfully completed

i'm doing some quick images, but we have round stars, and the offset it's correcting is pretty egregious:

Re: help with AP900 guiding via ASIAir Pro

Roland Christen
 


maybe reversed pins?)
Reversed pins are not going to reverse the commands to move. I assume that you are using ASCOM to control the mount via the USB connection. The move commands are software commands so they are not hardware related. If the mount is getting the commands, then it will move. I would try PHD2 for guiding, and once you see that the mount does what it's supposed to do, then you can try your other guide software.

thanks Rolando...I'm going to have a closer look at the guide logs to see if that is what was happening.  There does not appear to be a function in ASIAir to reverse the move commands as far as I know.  I'll be trying a new USB-RS232 active cable in hopes that it is a cable connection issue (maybe reversed pins?)
I also tried to get PHD2 going instead of the ASIAir, but having trouble connecting to the mount.  I'll try that again as well.

Re: Mach1 Grease kit were? is it hiding on the site?

Roland Christen
 

Yes, and I managed to break a cable on the Mauna Kea Visitor center 1100 mount doing a "regreasing" without thinking about the Dec encoder cable inside the mount.  Christopher was there watching me do it, but fortunately had all the tools and soldering iron in his truck for a quick repair job.

WARNING TO ALL REGREASERS!

Consider removing any cables going through the mount before regreasing operations. If you forget and spin one of the axes more than 360 degrees, you could damage your cables.

I share this warning from personal experience!

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.

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? 
--
You can set up the model ahead of time, during twilight, and do it on both sides of the mount. I set up my model 2 hours before sunset using Ha filter on my camera with exposures of .03 seconds. I could easily capture stars down to mag4.5. I would not take up precious clear sky imaging time to establish a model at night.

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?

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

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

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?
