AP 1600 strange problem with centering slew..

aircrftr@...
 

I've talked to George at AP about this and we are both stumped.... I'm using the 1600 with CP4 controller and have the encoders installed.  This has all worked for me since the time the cp4 came out, but this problem just started the other night, doing the same thing, with the same software as usual.  When I go to slew to an object, the scope will slew just fine to the object, but when I go to slew just a little more (within the field of view) say, after a plate solve to get back to the center of an object I want to image, the scope will not move.  This happens whether I do a plate solve or just slew to a random place and then try and slew just a little more so that the high speed slew is not activated, but only using the centering slew.  It seems the centering slew doesn't ever work now.  The errors returned are:
Sent; ':M_S#, ERROR; the operation has timed out.
Sent; ':M_S#, No response from mount.

It will do this no matter how many times I try slewing within my field of view (approx 1/2 degree) it will return these errors and not actually move the mount. 

I currently use the serial port with the serial to usb converter, but also tried the straight USB to USB connection between the CP4 and computer, direct.. and no help.  I also tried just using my minimal software to control the mount, being TSX Pro and APCC.  same thing still happens.

My computer/software setup is as follows:  (as I said earlier, everything worked beautifully with all this before)

Windows 8.1
TSX Pro,
APCC
MaxIM DL pro
Gemini rotator/focuser command center
Focus Max 4
CCDAP 5.10.6

I'm starting to think it's a problem within the CP4 controller, but I want to make sure before I send it in for repairs...  any help would be appreciated!

Hi Joe
Thank you for the tip. Unfortunately the AP technical support is not available for 10 days.
I will have to wait I guess. Thank again.

Hi Vince,
    Use a drop of “replaceable” (blue), LOCTITE thread locking seal ? It will hold the screws in place nicely, but can still allow removal or just loosening, if needed. That would be my first choice, but confirm with AP.

Hi,
 
I am having some issue with the springs holding the worms in DEC. I screw the bolts fully in and then I unscrew them by 1.5 turns. However after a couple of nights observing I check the bolts only to find that they unscrew themselves during the imaging session. What is the best way to set the tension on the worms and keep it there.

Thank you for your help.

Roland, I have a relatively new 1100 with encoders loaded last year by AP, and due to health issues last year, I am just this spring learning to use it.  Two Questions:  I see the blue lights on the encoder boxes when I turned the mount on and, after balancing and hooking up all the cables and the CP4, tested movement with the keypad. (1) does this mean that the encoders are on and tracking sidereal time automatically once power is turned on?  Also, I saw that an Encoders Utility dusk came with everything and I don’t know whether I need to do something with that disk before using the encoders. (2) what is the disk to be used for?  Many thanks,
Geoff

Hello Astronuts,

I posted tracking curve for our 1100 encoder mount for those who are technically interested in seeing how accurate it tracks. Also in the image is a test made with a high resolution (also expensive) commercial encoder that uses a relative encoder scheme. The difference is in the way interpolation is done in Absolute encoders versus Relative encoders.

Some people think there is no difference between the two, that the only difference is the need for a homing sensor in the relative encoder. That has never been the problem, what is the problem is the interpolation error that is inherent in relative encoders. The Renishaw Absolute encoder has undetectable interpolation error.

Re: New Website - Notification Lists?

 

Thanks! It is so much easier to get around isn’t it?

 

If you look under Order Info in the menu bar, you will see a Notification tab. It explains that we still have all of the lists and will use them when we open a new production run, for instance the upcoming 92mm run. No worries. If you signed up on a list, you are still on that list.

Love the new website!  One thing that isn't particularly clear is how the notification list process will work going forward.  It appears that these lists will no longer exists but you will still make telescopes and mounts.  If someone wants an RH305, for example, do you now need to wait until some are in stock and purchase on a first-come first-serve basis?

I don’t think that it was ever linked from the old site. I have asked Ray which videos are available and we will link to them from Technical Support.

Re: FujiFilm XT3 adapter

Stuart Heggie <stuart.j.heggie@...>
 

Well, you'll need some kind of adapter anyway and it is likely that a commercial adapter that allows Nikkor lenses as well as connecting to the telescope will be a) cheaper and b) have utility beyond astronomy. Seems worth considering since you said this was your daytime camera not a camera bought and modified to only be an astro camera.

Mike, I have not done this but it seems to me there should be an adapter to use Nikkor lenses on the Fuji camera. If there is, you can put that on the camera body then it would attach just like your Nikon camera did. Possibly with no change in spacers. Is the Fuji camera mirrorless? If so you probably have the back-focus for the adapter to fit without spacers.

Re: Worm mesh and PEC

Pawel,
 
    Don’t forget to SAVE the current PEC curve data first. before doing a fresh one.
You never know if your initial one, which can be restored,  was better to begin with. Would be nice if PemPro popped up a reminder to do so, or it would just save it automatically, as a backup, even for comparison tests.
