Re: RAPAS on Mach2

Dean,

 

I learned to take the RAPAS off after PA on my Mach1 because of cable catching problems.  So the same is probably true of the Mach2 too.

Now that is interesting.  Based on that bottom photo, taking the RAPAS off once you set the alignment of Polaris would probably be advisable.

Re: RAPAS on Mach2

Bill Long
 

The picture solved the puzzle.

Park 2 works great, that is what I always use when going out to align with RAPAS. Takes me a few minutes and I am back indoors and getting aligned further with PEMPro, which doesnt take much time to do. The the model gets running and I have a beer. 🙂 Or in lockdown mode, I have Spindrift Sparkling Lemon water.

To all with Questions on Mach2 RAPAS.    It can not be left on the mount in use, period.    If you don't put a weight at the top of the bar, it will clear the mount by some amount (I didn't measure, maybe 3/4"+-).   So basically do not use the top 1/2 or inch or so, you can check for those that get a Mach2.  Something to add to mount directions.    You can not move the mount right (east direction for those in the north).    I was using it with the weight at the top of the bar.     I will probably tape that or block it off somehow so I never go there again.    SO at least I can go west without hitting anything.   But it must still be removed in use.

Thanks for the person who recommended Park2, I've never used that one.. but I think that will work.   Park 4, 5, and 1 will not.   Park 1 can avoid hitting the RAPAS, if there is no weight at the top, but then the weight bar would be in the direct line of sight I believe of the polar scope.    Park 4,5 would hit the RAPAS housing (not the optical tube).   I'll take some pictures.

APCC COM PORTS

Steve Reilly
 

Yesterday evening I went to start the observatory as usual and ran into a rather unusual issue. To set things clear I use ACP/MaxIm/FocusMax/APCC to image with. I’ve used this for a long time with minor issues. Yesterday ACP Scheduler started the startup like always and everything appeared fine until the end. Usually the last thing is it unparks the mount. Here’s where it gets foggy. ACP is sitting there waiting forever to unpark the mount and nothing happens. At this point ACP can’t be aborted so it just sits and waits. The telescope is and has been connected and APCC is showing just that. I look at APCC and go to the park tab and tell it to unpark from last park position. Nothing, try again and a message flashes that says background activity…….or something to the sorts. I can not unpark the mount although I am connected. Connected via the LAN with Serial backup. I open the ASCOM driver and it says I’m connected but I see where it says COM Port 12. Wasn’t sure that was correct. A number of different attempts have happened at this point and I finally go through the list of COM Ports in the driver and when I get to COM 10 it connects. I try to unpark and it works….great except now ACP Expert won’t. That’s a story Bob and I will be working on shortly.

 

So what could have happened that changed the COM port in the driver/APCC? If the telescope was connected as indicated why couldn’t it be unparked?

I was curious myself and found these two pics that show how it attaches. First pic with both the bracket and the RAPAS and the second pic with the bracket on the Mach2.



Re: RAPAS on Mach2

Woody Schlom
 

Bill,

 

Yeah, I was with you not understanding how it could be possible to hit the RAPAS with the CW’s until somebody mentioned that the RAPAS doesn’t mount on the Mach2 the same way it mounts on the Mach1. 

 

Now that I think about it, I do think I once saw a photo of how the RAPAS mounts on the Mach2 and I thought it looked very odd.  Since I don’t anticipate ever being able to update to a Mach2, I didn’t pay it much attention at the time.

Re: RAPAS on Mach2

On both my mounts, 1100 and Mach 1 the RAPAS is installed at the rear of the RA axis where the tip/tilt plate for calibrating it is located. I am confused as to how on earth a counterweight could ever come anywhere near contacting it. Perhaps a picture of your setup would help?

Park 2, Park 4, and/or Park 5 will all work to keep the OTA out of your face while using RAPAS for alignment.

What about from Park 2 ?

When I first got my 1100 mount I was setting the polar alignment while the mount was in Park 3. I had to set the alignment and remove the RAPAS before I could attach the scope and camera, then Roland suggested to put the mount in Park 2. Problem solved.

No, not that easy. You would have to re-do it with PEMPro if you run it with another mount in between.

I thought I'd confirm, for those interested in using the Polemaster, that my exposure time increase did fix my accuracy issues in the fine tune step of polar alignment.
Last night, I measured a DEC drift of essentially zero again in PHD2 using only the Polemaster.      So if you're getting poor results, like I was, turn up the exposure time.   I was previously turning up both exposure and gain, last night after thinking about gain vs. exposure, I turned up just exposure and received the same good results.   So I have to retract my first post comments about accuracy, the Polemaster can do a very good job.

I also adjusted my RAPAS, to the best that I could do.. this is a tricky process, in the dark, with two small allan wrenches.    I tried some repeatability tests, plugging and unplugging the RAPAS.   There is some small amount of seating that I noticed.. that I need to wiggle (wrong word but don't have the right one) the RAPAS bracket, for the image location to stabilize.   It's more grabbing the bracket and flexing back and forth.. but it was repeatable and now that I know I must do it, it's ok.   Next time I will check how good the RAPAS polar aligns compared to Polemaster.

As a public service warning: 
Note, that while in the dark, be VERY CAREFUL about rotating a Mach2 with RAPAS attached.   My head does not allow me to get my dominant eye (right eye) into the RAPAS with a telescope installed.   So I have to rotate the scope to opposite side of RAPAS, for me it is west, and you have to be careful you don't go too far... because the mount/weights can and will hit the RAPAS and if the weights are up high, it doesn't have to go very far!    

I think APCC or the driver should have a message come up when you unpark Mach2 mounts, that warns you that you should remember to remove the RAPAS or pay careful attention to your rotation  and RAPAS so no collision occurs.  All of my prior mounts only had polar scopes on the RA axis of rotation, which never have to be removed, so I never gave it a thought.

No, the gear angles have changed.

I could just re-upload the curve after a swap, right?

Bill,

 

No, control boxes cannot be swapped without losing the PE curve.

Quick question -- I have an 1100 with AE and a CP4 and a Mach 1 with CP3-V2 Chip. If I wanted to, would I be able to share the CP4 between the two mounts? Assuming that any curve stored in the CP4 would be for use with the Mach 1, and the 1100 would of course just use the encoders.
