Controller Safety Cover

Steve Reilly
 

So it comes back to me that after having had a roof failure and rain on my system a few years ago I had decided I needed to find an alternative mounting location for the controller on my AP1200 to try an give a more protective environment. In fact I had thought that mounting the controller much like the AP3600 on the side with it in a vertical position would give it less chance of moisture getting in and then adding some type of roof over the controller itself similar to the plastic vented locking covers we use to use for thermostats in public areas but never got around to that little project. So rather then reinvent the wheel I thought that maybe I wasn’t the only person to pursue this and it might be prudent to see if anyone has done this already and what they came up with.

 

Of course I also realized the need to re-engineer the roof design and raise the roof and perhaps lower the pier so the telescope could be in any position and safe from a roof closure. The idea of using a elevating pier also came to mind but anything mechanical is subject to fail so….At least with the roof designed in such a  way as to have clearance at all times I could have a rain sensor designed just as an emergency backup to close regardless of any computer program. As long as the roof motor and controller has power, and my longest delay would be 60 seconds as we have a whole house generator and the observatory is covered by the generator, the roof could close at the first sign of rain although in practice the roof should already be closed from the cloud sensor. In my case the scope was safely parked, cloud sensor read very cloudy, and I believe it was in the process of a controlled shutdown but the computer had lost communication with the mount so it just sat there wide open.

 

I was on rescue squad duty as I always ran on Thursday nights for a number of years and thought nothing of letting it run as it has done so for a very long time with automation software. Shoulda, coulda checked on the status as I did have Team Viewer on the home network and on my smart phone but was on fire standby when it started to rain and I was otherwise occupied. Needless to say I haven’t let the system run again when I wasn’t home. Not until I find a reliable way to make sure this type of scenario can’t happen again at least. Of course I realize that everything mechanical is subject to fail I at least can cut down those odds by making certain changes.

 

Luckily for me the only real damage was the indoor/outdoor carpet and padding but worst of all the CP4 had some issue that Astro Physics was able to repair. I was able to check out the rest of the mount because I still had access to the old CP3. Fortunately my STL-11000, Pyxis 3” rotator, and such suffered no damage even though power was still on when I arrived home that morning at 0630 and saw the roof open. There was no sleep that morning to be had even though I’d been up running calls most of the night. Something about the unknown just doesn’t accommodate sleep well.

 

So if anyone has made modifications to their mount for the purpose of protecting the CP3/4 I’d really like to hear what you came up with. This is a bit late, like 2 years probably, but after a close call the other night it brought back all that experience and the urgency to make some changes. As my roof is now when the scope is parked the roof is 6” from the OTA. I have engineered trusses for the roof structure. What I need to do is determine the fullest height the ota gets and measure that so I know how high to raise the roof and how much I can lower the steel pier.

Re: Early meridian flip using APCC and SGP

Geof Lewis
 

John,
I don't have APCC, but I do use SGP and I can set either positive or negative values in the Meridian Delay setting of the V2 driver, which SGP then uses to either advance or delay the meridian flip, so maybe try that. It's something that you can test during the day, just to see how the mount slews with different settings.
Good luck,

Geof

Hi everyone,

Know this has question been asked before, but noticed that late last year the latest version of APCC allowed a negative meridian flip to be passed to SGP

Can someone briefly explain how I do that in APCC? - e.g. if I want to get APCC to tell SGP to flip the mount 1 hour before the object I am imaging has reached the meridian?

Re: APCC bug?

Ray Gralak
 

You need to make sure all applications are disconnected from the driver before the virtual ports can be closed. APCC will not close until all applications are disconnected from the virtual ports, including the ASCOM driver. You can learn about the status of the virtual ports by reading the help file. In case you can't find it, the same info is available online for you to read:

https://siriusimaging.com/Help/APCC/virtual_ports_tab.htm

So, if APCC is not closing then you need to figure out which application is still connected to the driver and disconnect it. If you used task manager to kill an application connected to the driver then that application obviously will never be able to disconnect from the driver and the driver will appear to not want to close. In that case follow the procedure in the driver's help file to shut down the driver:

https://siriusimaging.com/apdriver/help/index.html?top_of_handbox.htm

Sometimes I just want have the imaging programs open by themselves,
but it does not seem to be possible.
If you want to start an application by itself then do NOT connect that application to the mount because that will start the AP V2 driver which will start APCC. This is a very basic concept common to all ASCOM applications and drivers so I hope it is now obvious.

Note that it may be helpful for relatively new users of APCC and/or the driver to read through the APCC and AP V2 driver help files. It will save us time having to repeat the answers to questions already answered in the help.

There sesms to be a bug in APCC, which is that the program will not close if any other applications which use the
ASCOM driver are running, such as PHD2, Sharpcap, or SGP. If I disconnect the mount and hit the close X, APCC
tells you that other applications are running, and asks if you want to close, but even if you say "yes", it does not
close. Sometimes I just want have the imaging programs open by themselves, but it does not seem to be possible.

Dale,
So I misunderstood what George said "It may be a better decision to update the CP3 to a CP4".

I have the ROM chip version Q and I thought maybe I should just replace it with version V.
For the PEC, I retraced the PE of my Mach1 with PEMPRO and therefore I have the corresponding PEC in stock. So I could reassemble it on CP4.

Thanks

The CP4 is completely different hardware. You upgrade to one by buying a CP4 from Astro-Physics and replacing the CP3 on your mount with it. The power connector is different, so you may also need to consider any cable changes in that regard, but the servo motor cables are the same. You can keep the CP3 as a spare or sell it. You will need to talk to AP about the possibility of transferring your mount’s PEC to the CP4, a possibility I believe that depends on how old or new your CP3 is.

The model operates in the background and does not affect any guiding program. It is totally transparent and will work nicely with PHD2 guiding. In other words, it does not fight the guider.

There are 2 different models depending on what equipment you have and what your goals are.

The CP4/5 stores the points, up to 64 per side, and does the calculations for pointing and tracking. It is a simplified version of a pointing/tracking model and will not tell you how far off your polar alignment is. It simply compensates for pointing errors and adjusts tracking in both axes with the polar alignment that you have.

This simple model is intended for keypad users. If you don't have a keypad and want more extensive modeling, we have APPC - APPM which has automatic image acquisition where you turn it on and come back in 30 minutes and have your model done automatically.  The keypad version of the pointing/tracking model requires hands-on operation. You physically click on stars in your planetarium program, acquire the image of the star, center it and manually enter that point via the keypad. You can also use a crosshair eyepiece for centering, but some kind of planetarium app (perhaps on your smart phone) is needed to choose the stars for your pointing/tracking model.

In the case where you do not have a planetarium program handy to create these star points, and you just want to do unguided perfect tracking, we have a tracking model (no pointing). This model maps the drift along the object's path that you want to image. You only need to measure the actual drift at 3 or 4 points along the image's path in order for the CP4/5 to calculate the exact custom RA and Dec rates that will produce perfect or near-perfect tracking along the entire path over the course of the night. I have tested this model extensively and it works very well. Unguided imaging with my encoder mounts is very accurate and appears to be as good or better than guiding for the same exposure times (between 5 and 15 minutes).

We also have a third routine that measures your scope's orthogonal error and compensates for it when flipping sides.

I hope I have answered your questions and not confused things further.

This simple model is intended for keypad users. If you don't have a keypad and want more extensive modeling, we have APPC - APPM which has automatic image acquisition where you turn it on and come back in 30 minutes and have your model done automatically.  The keypad version of the pointing/tracking model requires hands-on operation. You physically click on stars in your planetarium program, acquire the image of the star, center it and manually enter that point via the keypad. You can also use a crosshair eyepiece for centering, but some kind of planetarium app (perhaps on your smart phone) is needed to choose the stars for your pointing/tracking model.

In the case where you do not have a planetarium program handy to create these star points, and you just want to do unguided perfect tracking, we have a tracking model (no pointing). This model maps the drift along the object's path that you want to image. You only need to measure the actual drift at 3 or 4 points along the image's path in order for the CP4/5 to calculate the exact custom RA and Dec rates that will produce perfect or near-perfect tracking along the entire path over the course of the night. I have tested this model extensively and it works very well. Unguided imaging with my encoder mounts is very accurate and appears to be as good or better than guiding for the same exposure times (between 5 and 15 minutes).

We also have a third routine that measures your scope's orthogonal error and compensates for it when flipping sides.

I hope I have answered your questions and not confused things further.

Subject: [ap-gto] Where are new models data stored?

Are the models stored in the keypad or the GTOCPx?
