Re: APCC COM PORTS

Actually in the observatory and both programs and driver are up to date but by itself I can not get the scope unparked. I’m dead in the water. Any suggestions? I have the driver set to use the IP address for the mount and testing says it finds the mount. But I can’t unpark.

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?

Dean, you are correct, you don't need to use a park position.    I was just slewing the mount a bit west, enough to get my head in there to look through the scope with my right eye.  This is after running into the weights the first time out, I was a bit 'skittish' myself.  Don't want to ruin my new toy so quickly.   

Just some warnings in the instructions would have sufficed (don't put weights high, don't go east, and do not leave it on the mount).     It just never occurred to me a polar scope would interfere with anything.     It is certainly made well,  like everything else A-P makes, and I'm sure will be accurate to a level necessary for doing most things.

Hopefully with the through the mount cabling, cable snags on the RAPAS shouldn't be much of a problem.  Having the mount strike the RAPAS seems to be more of a potential problem though.

Re: FAPAS vs. RAPAS

Robert Berta
 

As I am in Michigan, the RAPAS is fine with my 1100 and 900 mounts and 6" refractor/11" SCT but my club has a 8" D&G refractor on a AP 1200 mount. That long tube (f15 as I recall)  means the mount has to be mounted quite high above the ground so a RAPAS would require a ladder to use it. In that case a 45 degree prism would be ideal. Currently we are using a straight through polar finder....but that means you have to crouch down to use it....so a 45 degree would be ideal. Luckily the mount/scope stays in our dome observatory most of the time but would be nice to have that 45 degree version. So put us down on the side of a 45 degree version. Now that I think of it, even with my own mounts/scopes....a 45 degree version would work fine also.

Managing early pier flip.

Wayne Hixson
 

I’ve got my meridian limits mapped to trigger an early flip, but in some cases I want to manually set a limit to override the mapped limits, but having trouble figuring out how to do it. Say just set a flip at 1 hour East.

Hey Guys,

I'm a new owner of a fabulous AP1100 mount that I know is going to be awesome, but some troubles with getting started. First, I'm not new to this game, been an amateur astronomer for 40 years, climbed the upgrade ladder in hardware and software to this current setup with the 1100 mount, 12" LX850, APCC software as well as using Cartes Du Ciel.

I'm just getting everything set up and working and I know this is probably due to the loose nut behind the wheel not comprehending how this fancy stuff works, but.... My only real problem, at this moment is about doing a recal on a star after unparking and initialization. I think I've got everything okay in APCC for the initialization and unparking, the scope goes almost directly to Arcturus, but it's not quite even in the field of view of the 80mm piggybacked on the LX850 (hence my assuming polar alignment issues). Therefore I have to then use APCC to move the scope to both find and center Arcturus and then when I try a recal so I can eventually then go somewhere else, it tells me I can't do that because I moved the scope too far. I strongly suspect IF and WHEN I get it polar aligned it won't be so far off and this might work and maybe I am doing things properly, but...... I tried a sync once which seemed to do nothing but as soon as I tried to go somewhere else the scope flew off to "who knows where" and was totally lost in space. After repositioning the scope with loose clutches and sending the scope to Park 3, then aligning the marks and tightening the clutches; All was well with the Universe again!

I guess I don't understand the recal and sync functions, even though I have read and re-read the documentation, clicked the question mark in the software and read that info, etc. perhaps I am too thick between the ears to get it; at  least yet.

Thanks for listening and hopefully someone can shed a little light on my concerns and dim brain right now.

Re: RAPAS on Mach2

Terri Zittritsch
 

A few pictures:
Not the best of pictures, but you can see there is room if weights are not at top to move RA west, but not moving RA to the east (for us above equator).   I like the idea of using park 2.   Basically don't move RA at all..  and I would not have to worry about weights.      And just remove RAPAS when done.



Re: FAPAS vs. RAPAS

Christopher Erickson
 

I am hoping that some day AP announces a FAPAS.

A 45 degree polar scope. I am just under 20 degrees North Latitude here in Hawaii and the PASILL is too low and, for me, the RAPAS eyepiece is too high and also interferes too much with the OTA, cables, cameras, etc. to be as convenient as I would like. And a prism diagonal would potentially be able to shorten the height/length of the eyepiece and field tube, meaning less interference, cable snagging, etc.

Just a crazy thought.

Re: RAPAS on Mach2

I suppose depending on how long the OTA is or what kind of camera is attached that it might be difficult for someone to look through the RAPAS with their right eye when the mount is in Park 4, and especially so from Park 3, but from Park 2 there is no possibility of interference.

Re: RAPAS on Mach2

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.

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.
