Re: Getting Files from Remote Systems

Mark Striebeck
 

I use Google Drive in a similar manner: map my imaging directories to Google Drive directories and they get backed up automatically. I also keep my local machine that I'm processing the data online, so the next morning all images are locally available.

I also have a "Staging" Google drive directory where I store all my images from objects that I'm still working on. On my local machine, I go through the files, delete the bad ones and move the good ones to Staging. While I can now process them there further, this will also delete the files on telescope computer making sure that it doesn't run out of harddrive space.

And all the file transfer stuff happens in the background, i.e. I never have to wait. And the files are automatically backed up in case one or both machines die.

Re: Guider exposure times?

Mike Shade
 

Thanks for the input on this.  As we are now in the heat in SE AZ, there is a bit of ground heating during the day, in spite of my tree planting 20 years ago.  I did notice with the shorter guide exposures, the error graph in Maxim looked better, smoother and there was significantly less variation.  I did a series of tests last night pointing the scope at various elevations and doing a 1 minute unguided shot.  I was testing for some sort of sag or flexure in the optical components.  The results were interesting.  I shot at 85, 75, 65, 55, and 45 degrees elevation, pointed E, W, and then S.  In a series of several at the same location, the stars were all sorts of interesting shapes...round, ovoid in one direction, ovoid in another direction.  As there was no guiding, the only "live" axis was RA and the deviations were not tracking errors as they were not in line with this axis.  Interesting demonstration, at least to me of the effects of seeing variations.

Curious as to what people have for guider exposures for various systems.  Was having some issues guiding my 1600/CDK 17/Maxim 5.18/STL6303E (guiding with camera) in that the stars were not always round...almost but not quite, just a few pixels but enough to oblong the stars.  Always had somewhat longer guide exposures (7"-10") to try and even out seeing variations (which can be quite large with a 17" telescope).  The system can go unguided with reasonably round stars for the 382" worm cycle near zenith but guided images were a different story (I do need to guide the system).  So last night lowered the guide exposure to 2", aggressiveness to 5 and round guided stars.  What I think might have been happening is that with a longer guider exposure, there would be centroid changes between exposures and the system was reacting to these.  With a shorter exposure, this is not happening as the "deviation" is not allowed.

Re: Diagram of (top of) Eagle Pier

fd@...
 

What a coincidence.  I am designing a top for my Eagle Pier so I can mount a tracker on it.  Now that my Mach1GTO is on a permanent pier, I want to put my Eagle to good use.

I based my design on the drawing of the ADATRI adapter that fits on a pier and holds my Mach1GTO. 

Mechanical drawing of what I came up with so far:

I decided to 3D print the part so I made a couple changes to dimensions, for example the three side holeshttps://imgur.com/0bcY90Zhttps://imgur.com/0bcY90Zhttps://imgur.com/0bcY90Zhttps://imgur.com/0bcY90Z are bigger to accommodate barbed brass inserts.

I think you are trying to download using the wrong link on the CCDware downloads page. There is a link just above the PEMPro section to another download that is susceptible to getting virus check errors.

 

The link for the PEMPro download is below the PEMPro section, not above it. Here is a screen shot:

Re: Guider exposure times?

dnakic@...
 

I have AP 1600GTO with PEM training running around +/- 0.74.  I have a 14” Edge HD @f11 and imaging with STXL 11K and guiding with its SXTL filter wheel/guider.  I use Maxim DL with 8/8 X/Y aggressiveness.  Guide calibration is 4 sec and 4 sec for guide exposure.  My guiding is +/- .5 arcsec when watching the guiding trace.  My imaging with narrowband is typically 20min in duration.  Early on I noticed my STXL fan was creating vibration and causing oblong stars.  I now run with fan off, but it does go on when it reaches a critical point.  You may want to try running with fan off too.

I’m enclosing a sample of what I’m getting with this setup.


Re: Guider exposure times?

Dean Jacobsen
 

My experience has been that guiding camera exposure times will vary according to how steady the sky is.  You want to have exposures long enough to average out the seeing so you aren’t chasing a false centroid calculation by the guiding software.  For me, I want to keep my guide exposures as short as possible because I dither the guide star every one or two exposures (for better pixel rejection during stacking, “walking noise” issues with my camera, and because I frequently use drizzle integration) so I want to minimize the settling time before the next exposers is started.

I generally use 3 sec for calm nights but will use 5 sec for nights with bad seeing.

It is very instructive to watch seeing scintillation at longer focal lengths with an eyepiece and see how a star will move around.  Then you can easily see how short guide exposures will give you an inaccurate result.  Also, try taking a 1 or 2 sec exposure with your guide camera.  If the star is misshapen or elongated then you might not be getting an accurate position calculation.

Re: Guider exposure times?

Michael Hambrick <mike.hambrick@...>
 

It seems that I read somewhere that shorter guide exposures are better, but I am not sure where I read that. In any case I have always tried to go for 1 to 3 second guide exposures. I use Maxim DL-Pro and sometimes CCDOps. My guider aggressiveness is typically about 7 or 8.

I have never really experimented a lot with these parameters or taken the time to set up a PEC, but I suppose that I should.

Try setting the connection properties like this:

 

 

You don’t need to connect the ASCOM driver on APCC connect.

 

If this still doesn’t work check that you have two Virtual ports defined. If you manually defined them at some point then APCC may not try to change them, so you may need to define the virtual ports you want to use. You only need to setup the first two.

Re: Mach1 CP3 pier crash!! (Similar to CP4 crash in another thread)

Indeed. The only time my Pyramid shut down was in the summer heat. That week I placed a small fan to circulate the air around it and the problem went away.

Hi,
 
    You should be aware that under certain conditions, ANY Pyramid power supply, including the one sold through AP,  may NOT reset its “thermal breaker” after a dropout, for upto a half hour. So, you may give up and walk away too soon. Then all, is fine the next night, but the PYRAMID trips again. The Pyramid (old linear technology) supplies are not very efficient, but are generally well designed. Just heed their warnings and limitations.
 
    If you still have it, carefully read the Instruction Sheet.
Here is  Section #5,  which I transcribed from mine. Substitute “TRIP” ... for their word  “WORK”.
Yes, it does “work” as designed to do. The power supply breaker will trip,  eventually, even if there isn’t an immediate short circuit overload. So, any long duration or repeated mount slews, will eventually have the Pyramid protect itself, so you can take an imposed  coffee break, before going back to imaging :-)

 

(A-5)  WARNING / DEVICES.

 

THIS UNIT IS WELL BUILT WITH A WARNING!   SHUT DOWN FUNCTION.

THE WARNING / SHUT DOWN FUNCTION WILL WORK  -  UNDER THE FOLLOWING UNUSUAL STATUS:

 

1)    THIS UNIT IS USED OVER 15 MINUTES AT 100% OF RATED LOAD.

2)    THIS UNIT IS USED OVER 25 MINUTES AT 80% OF RATED LOAD.

3)        THE OUTPUT OF THIS UNIT IS SHORT-CIRCUITED/OVER LOAD/OVER TEMPERATURE

 

NOTES:

1) IF THE WARNING/ SHUT DOWN FUNCTION IS CAUSED BY THE ABOVE ITEMS # 1 AND 2 THEN THIS UNIT WILL RETURN TO NORMAL WHEN THE WARNING/SHUTDOWN FUNCTION CONTINUES TO WORK ABOUT 15-30 MINUTES.

2) THIS UNIT IS INTENDED TO CONTINUOUSLY WORK AT 70% OF RATED LOAD DESCRIPTION OF THE WARNING / SHUT DOWN FUNCTION:

STEP I.  THE OUTPUT SHUT SHUT DOWN.

STEP 2.  GREEN LED OF NORMAL OFF

STEP 3.  RED LED OF PROTECTION ON.

    Hope this helps explain the situation you had been having. Check you device power requirements.
When it happened to me, the overload eventually tripped the PYRAMID, and while I was away from the mount for a short while, the power supply cooled off and came alive – and the mount resumed its slew, right into the pier, before I could hit the main power switch. I wish the Pyramid would have stayed powered off, but it seems to have been designed to reset and resume without warning and “unattended operation” – NOT always a good thing.
