Re: Automating Meridian Flips with APCC Pro and with Sequence Generator #APCC

I am researching setting up automated meridian flips with Sequence Generator.

I have set up a one hour [15 degree] meridian delay in in APCC for point mapping and then for imaging past the meridian.

What I am wondering is whether the information concerning my APCC defined meridian delay is accessible to SGP and is is used by SGP in calculating the modified meridian position?

I can't find any information on this in the documentation.
Dean, I use SGPro and APCC very successfully with the Mach2.      I set my meridian limits using the editor and enable those limits.   After doing this, and picking a target that is within those meridian limits (early flip area - bring weight up or imaging past) it works with SGPro sequences.  IN fact you can test it prior to actually imaging, just pick a target in the early flip area to see that it starts weights up.    I've never had to change a thing in SGPro.   I do have the box checked on the meridian tab to send limits to SGPro.

I've tested it to the limits to where it goes to my target, in some cases almost 3 hours before a normal meridian flip.   Works great.

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.

I think what you're explaining is your new hand controller SW for the mach2, can you say when it might be available?    I'd like to be able to use the hand controller at some point, even if it doesn't have all of the fancy features enabled yet.   Right now, always teathered to my PC.  I don't want it before it's ready, but is there some outlook?


Thanks,

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

Christopher Erickson
 

If I remember correctly, although I was just assisting Roland, *I* was the one who spun the axis around and tore the cable in half on the hard plastic cable guide that comes with the 1100/1600 mounts.
 
I also don't use the hard plastic cable guides any more either! I now have two of them that live in my spare parts bins.

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.

APCC and APPM is amazing

Finally had a night with decent (not great – 2”) seeing, and this is part of a run with my 1.6 meter focal length very long refractor (AP206).  1600 mount with encoders.

 

Large APPM model I did back in February, which now works better with the latest APCC.

 

It wasn’t this perfect all night, but no guiding was needed at all during this interval:

Re: Going Unguided With a Long FL Scope?

Mike Dodd
 

You've accomplished a remarkable recovery. :)
Sorry about the stroke - good to see your still at it!
The interesting thing is, the scope arrived while I was in the rehab hospital, so one of the first things I did after coming home was to install it on the AP1200 with the help of my wife and daughter. It was a bit scary mounting a 130mm APO with only one good arm and hand!

I've recovered about 95% of my left-side functionality.

Thanks for the good wishes, fellas.

If people are using FITS Liberator to import photos into Photoshop for processing, it defaults to: mirror image (or some language to that effect) and you have to uncheck it most of the time (unless you know for sure your images are flipped). Maybe?

Hehe,

Yeah...I was wondering about a 130 mm guide scope :) Sorry about the stroke - good to see your still at it!

In the end I went and ordered an Optec TCF-Leo which should allow me to use an OAG with the C11 Edge - if I want too.

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.

I'm impressed! Your guide scope is ten times the aperture of your
imaging scope! I'm sure you meant something different. :)
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?)

doing our first light remote, and the technician did a very rough polar alignment. the stars were visibility moving across the screen every 10 second exposure, despite having an AP1600 with absolute encoders. 

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!

Gease kit was already SHIPPED today that was fast!   Here is my current steps.  Looks okay, I don't see crud... but I suspect a hair or shaving of metal can bump it.  I have some snaps and a video just disassembled. Grease to come monday UPS.

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: Last night tracking with Mach2

Is the Astro-Physics PEC Processor an "in-house" only application?
Yes, we use it for multiple test and setup sequences on our encoder mounts.
