Dear All,

Over the Summer I collected 19 hours of data on Pickering's Triangle using the AP1100GTO with a 10in Newt. Today my image was selected as image of the day on Astrobin! 

This Summer I built an observatory in my backyard and have now a Mach1GTO (soon to be replaced by a Mach2) and an AP1100 on two piers. Not having to set up every night I image has been such a huge step un in quality of data and life! 

The high resolution image with full acquisition details is on astrobin: https://astrob.in/xm1fcn/0/

Happy belated Thanksgiving!

Re: 130 EDF Starfire Field Flatteners

Roland Christen
 

Most likely our standard GT/GTX flatteners will work on TMB scopes. However, these flatteners require the Feathertouch 3.5" focuser with our AP dovetail adapter. It might be difficult to cobble together a suitable adapter for your scope.

The EDF field flattener only fits the 2.7" focuser that came standard with the 130 F6 AP scopes.

A question from a newbie on flatteners....

Will this flattener work on a TMB-130SS 130mm f/7 APO?

I have a Feather Touch focuser attached to the OTA with an AP #A1008
2.5" extension tube from the focuser to a Pyxis rotator.

Thanks for all information.

Re: 900 mount spurious RA motor slewing and stall

Roland Christen
 

You may have a failing motor encoder or bad connection on the cables going to the axis that is running away uncontrolled.

You can try this: plug the RA cable into the Dec axis motor, leave the Dec cable unplugged. Then push East and West buttons and see if the motor moves properly. If that motor also runs away, you probably have a failed Y cable. Check the wiring on the cable connectors to see if any of the wires are broken or frayed. Check the connector pins also for any oxidation which would cause bad contact.

If you cannot do these tests or can't find the problem, call George on Monday and he can run you thru a couple of tests that will determine what the problem is.

Whenever a motor runs away it is because the controller is not getting a signal from the motor encoder that the motor is turning. The controller then sends more and more power to the motor (which causes the motor to run faster and faster) until the software decides that there is an open loop from the encoder and it shuts off power to the motor. It usually gives the motor loop about 2 seconds before shutting the motor, in which time the motor will run at uncontrolled speed for a number of axis degrees, as you experienced.

Subject: [ap-gto] 900 mount spurious RA motor slewing and stall

Hey everyone, longtime AP900 user and lurker, with a problem that just cropped up.  I'm the original owner of a 900 mount for around 20 years now, and recently upgraded to the CP4 (with new motor cables and new 2-pin power cable).  It's been working pretty flawlessly with the CP4 and APCC pro for months, but all of a sudden is giving me a motor movement and stall problem.  Yesterday it would slew East/West OR North/South fine, but when both motors slewed together at any slewing speed, the motors sounded strained and sped up and slowed down in a jerky fashion.  Sounds like a power problem I thought, so I moved to a different power source (Powerwerx 30 amp supply, nothing else plugged into it, volt meter showing 14v output).  Same problem.  Today, it's much worse -- as soon as I boot up APCC Pro and click Initialize, the RA axis slews 10-15 degrees (OTA moving to the west) and the motors stall.  So I unplugged everything from the CP4 except for the motor cable, and pulled out my old AP hand controller, to make sure the problem wasn't coming from an external source. 

The first message on the controller is to select my location and then press go-to.  As soon as I press the goto button, the mount slews in RA by the same 10-15 degrees, and  again the motors stall.  DEC axis does NOT turn, only RA.  The next controller screen shows the options on how to unpark.  If I choose unpark from current location, I get to the main menu -- but the moment I press ANY direction button, the mount slews another 10 degrees in RA. If I choose 'new setup' and resume from park 3, it immediately does the same thing - slewing 10 degree in RA into a motor stall.

I have the APCC logs here to show the motor stall upon initialization: https://www.dropbox.com/s/m73pia2yv4grc6t/ApccZip-Ken_Sablinsky-2020-11-26-212842.zip?dl=0

But since it happens with only the hand controller connected to the mount, could there be a problem in the CP4 or one of the motors?  I don't have another 2-pin DC power cable to rule out a problem cable. Any ideas as to how to pinpoint the problem?

Re: 130 EDF Starfire Field Flatteners

I would buy 2 of them, Roland. 

I have a 130 GT at one home, and a 130 GTX at another..
We have flatteners for the 130F6.3 GT and GTX.
The scope that we ran out of was a much older 130F6 Starfire, which had a different optical design and will not work with the newer GT/GTX flatteners.

Re: AP Driver V2 5.30.10

I can't think of any reason that a change in the driver would affect guiding. PHD2 is not a simple program, so any settings error can cause guiding issues.

I have one, an f/6, and would like a field flattener for it.

Happy Thanksgiving, Roland.  Definitely add me to the list of people interested in the flattener for the 130EDF.  I have a late model from 2002 or 2003 (S/N 421), the version with the FeatherTouch focuser.  I keep thinking that this scope calls out for a larger-sensor camera if I can get a good-quality flattener.  Thanks for not forgetting about us.

Re: 900 mount spurious RA motor slewing and stall

Actually, I had a similar issue happen with my Parallax 250 mount which uses the AP GOTO system.  Auto-slews upon resuming from Park and/or touching any handl paddle buttons or with SkyX.  After much time with George and Joe (Parallax) on the phone (bothe were very helpful), and swapping the RA & Dec motor/encoders around, it turned out to be a failed RA motor/encoder.  The fix was easy, a new motor/encoder with AP installing an anti-static circuit board too.  Trouble is it took a couple of months to get the servo motor from Maxum, routed through Parallax to AP then back to Joe then to me.  Both shops were great!  The swap out took all of 5 minutes, then everything worked fine.  Certainly not a cheap fix but a straight forward one.  It's been a few years but, as I recall, the bum motor/encoder also messed with the DEC.
