Re: AP1100GTO Guiding Irregularity (changes with CW arm position)

Roland Christen
 


Guiding is normally a function of your guider software settings and also a function of the seeing at any particular time. To judge the seeing effects just turn off your Dec guiding so that the Dec axis stays still and does not move. Then record the Dec RMS value and you will have the seeing component of your guiding error. Check also that your guide star is well focused and reasonably round. A guide star that is comatic, astigmatic or defocused can ruin good guiding.

Subject: [ap-gto] AP1100GTO Guiding Irregularity (changes with CW arm position)



I've noticed that my guiding is not uniform and changes depending on the angle of the CW arm. So, if I'm guiding with the CW arm at a 45 degree angle (like the angle when in park 3) my guiding numbers are usually around .4 or .5 RMS for RA and Dec.

But if I am guiding with the CW arm more or less parallel to the ground (kinda near the position of a meridian flip) the guiding goes to around .7 or .8 RMS for RA and Dec. 

As the night progresses I can watch the guiding improve as the CW arm slowly goes above the parallel position.

Is this normal behavior or is there something amiss in the gearing?



Re: Balancing AP1100 Gto

Woody Schlom <woody@...>
 

Vince,



It’s current you want to look at. Current is measured in watts or amps. “V” stands for volts. Maybe somebody will correct me, but I don’t think it really makes much difference which side (Source or Load) you read on current. But given a choice, I’d read the “Load” side.



If you’re using a decent power supply, I don’t think volts should change. Voltage “should” be regulated and remain constant.



But watts or amps will change when you slew. You’ll see one low constant reading while the mount is just tracking. Then when you press a motor move button (at highest slew speed – that will show the greatest current change), current drain (amps and watts) will go way up for a second (spike), then settle down. It’s the settled down current reading while slewing I look at when balancing – not the quick “spike.”



And the actual numbers aren’t important either. All you’re looking to accomplish is to get the meter current numbers (amps or watts) to be the same in both directions. That means the motor is working equally hard in both directions – which means the mount is balanced.



Current draw will be greatest when the CW’s are parallel to the ground. So when I balance using a current meter, I start the move with the CW’s below level. When I first press the motor move button, the current spikes (goes way up) because the motors are working very hard getting the mount moving. But once the mount is moving at slew speed (less than a second), current drain will level out. That’s when I look at the meter’s current load (amps or watts, doesn’t make a difference – but pick one and always read the same one) and write it down.



Then I press the reverse motor move button and do the same thing – wait a second for the “Spike”, then write down the current load (same one you observed before) and write that down.



Until the mount is balanced, these two numbers will be different. The higher number (amps or watts) means the motor is working harder because there’s more weight the motor has to lift in that direction. So move the CW’s slightly (1/4” perhaps) to take weight off the side where the amp or watt readings are higher – and repeat the process.



After moving the CW’s slightly, you should notice that the amp or watt number in the higher direction has gone down, and the amp or watt number in the lower direction has gone up. It the opposite happens, you moved the CW’s in the wrong direction.



Keep doing this until the meter reads the same number of amps or watts in both directions. And there’s no need to get the numbers exactly the same – just close.



I hope this helps. If necessary, I can unpack my meter and one of my mounts and give you more detailed instructions, but I’d rather not have to do that as that would take me a couple of hours all told.



Woody

Hi

I have purchase and installed a Powerwers meter but all the numbers seem to change when I power the motors so I am not sure which number I should be looking for.

On the Source side I have A and WH

On the Load side I have V and W

Which of those number should I be looking at. I don't know a lot about electric so I just want to make sure i am doing the right thing.

many thanks for your help.

Re: APPM/APCC: Enabling the cooler of an ASCOM Camera?

Ray Gralak
 

Hi Karsten,

I connected a camera in APPM via its ASCOM driver, which worked really well. However, I noticed that APPM does
not allow me to set a cooler temperature, or to enable the cooler of the camera. Maybe something to consider in a
future release? Unfortunately, the properties dialog of the ASCOM camera driver does not allow me to define a TEC
temperature. Thus, the camera runs uncooled if I would choose to control it throught the ASCOM driver, and not a
3rd party program.
The plate solving applications ignore background noise in images so there is usually no need for cooling.

Hello everyone,

 

Spring is struggling to find a foothold here this year and in many parts of the country. It is time to be inspired to get out with your scope and hone your imaging and processing skills.

 

We hope to see many of you at the NorthEast Astro Imaging Conference (NEAIC) April 19 and 20 (next Thurs and Fri) and the Northeast Astronomy Forum (NEAF) April 21-22 (Sat & Sun).

 

Stop by to see us at both venues. Roland, Marj, George, Howard and Karen will be there  and we’d love to show you a few new goodies that have been developed.

Hi Andrew,

If it solved your issue, I'm optimistic that it will also work for me.

Thanks for offering to print one for me! Whenever it's convenient, please leave it at Starizona and I will pick it up from them. Thanks again!

Re: CP4 Not Connecting to Local Network

Thanks Robin. 

I don’t know if it would solve your wifi issues but it will give you more signal to work with. Whether that will be enough, I don’t know but it’s worth a try.

I would be happy to print one for you. You could pick it up from my place, we could meet at Starizona during an observing session or I could leave it at Starizona for you.

Thanks George and Ray for your replies.

Although was you said is totally true for Win7, it is less true for Win10, has Microsoft is now doing dynamic scaling
to support variety of display contexts (e.g. dual monitor with different DPI).

I believe it's a valuable goal for application developers to support it as well.

My need for changing the display scaling came to do the panoply of applications we use in astrophotography.
APCC is certainly one of the more readable and the layout is excellent.. but it doesn't cope well with changing of
dot pitch.

I don't think Microsoft will go back to the former Win7 strategy. Apps need to adapt to this new reality.

Re: APCC UI not adjusting with Win10 display setting change

Ray Gralak
 

APCC is built "DPI Aware" but the actual rescaling of elements is done by Windows and not the application. As I said earlier this is a known issue on Windows including Windows 10. It can only be fixed by Microsoft at this point. :-)

George, won’t this make the text too small to read on a high DPI display?
APCC's main window can be resized and the text will scale larger (no windows scaling necessary! :-)

As for other not so lucky applications, you can click on the Windows start menu and type "Magnifier" and bring up the Windows magnifier gadget. Using Windows magnifier you can have all that Windows desktop real estate *and* still read the tiny text.

Hi there,



I don't know if it's the right place to report an issue in APCC or not. Just tell me if I'm the wrong place.



I noticed AAPC UI is not scaling in sync with the Win10 display setting. When set to 125% or back to 100%
from 125%, the captions and text elements are not positioned correctly. I need to close/reopen APCC to get the
correct UI scaling.



Thanks!
