Nexremote and Skyportal, Need some advise
« on: January 08, 2018, 04:22:26 AM »
Hello, I currently setup my CGEM outside and use two usb 3.0 repeater cable that are 32 feet long. I connect my imaging camera to one of the cable and the mount and guiding camera to the other. Here is my issue. When I use Nexremote software on my laptop and I need to do ASPA (two stars +4 cal) then polar align since I don't have a view of Polaris. This my issue, as we know if I'm using nexremote software on my laptop the hand controller's ASPA is not in sync with what is going on with the laptop's nexremote ASPA. So the "enter" and "align" keys are useless as they don't acknowledge what's going on with nexremote on the laptop.I need to run back in the house every time I need to hit "enter" or Align" on the laptop during the ASPA process. This is very annoying and time consuming.

I have the sky portal wifi adapter, Could I use it after the initial ASPA (done with the hand controller)? After ASPA I could use Skyportal on my tablet next to my laptop to move the mount or goto's. I was trying this configuration but I know I have to align the skyportal software as well with goto objects.

Could this work? I also know Sky Safari works with the Skyportal WIFI adapter which it could be nice later on. All I want is to be able to do ASPA outside without having to run back and forth in the house and then do some DSO imaging.

Any suggestions? Thanks. Jay.

I use the physical hand controller to align the scope, then use Cartes du Ceil to send the scope to targets. Since I use Backyard EOS to image, it has controls to move the scope N-S-E-W. If you don't have other software to do that, NexStar Control Pad is a simple utility for moving the scope. This way you don't need to use your tablet.

yeah i use the nexstar control pad software(nexremote). I could do that but I won't have goto capability from the nexstar software since I never used it to align. I guess it would work but i would need something else for the goto's so I don't have to go out and use the hand controller to select a new goto.

You can use the Skyportal wifi adaptor and Sky Safari Pro 5 to align and control, you do not need to touch the hand controller. The Skyportal app can be used as well but it has a very limited sky map compared to Sky Safari. There are several threads on this. Forget ASPA with the hand controller, it is not really needed. If your imaging your going to need a laptop near your scope anyway, and why not simply use Sharpcap 2.9 Polar Alignment tool, which is free, and takes all of three minutes to get very accurate PA when your setting up your mount. I use Teamviewer running on my observatory laptop and a small HP Stream in the house, to control SGP, Metaguide, etc, via wifi.

NexRemote is a hand controller - the full hand controller (but unfortunately one only running v4 firmware) running on a Windows PC. You need the hand controller functionality to perform the initial alignment. You can get that from the physical hand controller OR NexRemote software OR SkyPortal or SkySafari software connected via wifi (the SkyPortal dongle) through an AUX port (or the inbuilt wifi in the Evolution mount). In the case of SkyPortal and SkySafari they are unique in that they have the capability of doing that full initial alignment built in ... that is very different than the vast majority of other scope control apps.

When you have the initial alignment done via one of those hand controllers you generally can't use another connected hand controller. The physical hand controller does however have a couple of functions that can still work when another hand controller is in control - that is the arrow direction keys and the slew rate change, both of which work directly with the motor controllers in the mount and won't affect another active hand controller.

NexStar Object List (NSOL) is not the same app as NexRemote. NSOL is a simple Windows based scope control app that gives you the goto capabilities to a list of objects and a simple set of movement capabilities (simple NSEW arrow keys). Just like with other scope control/planetarium type of apps you must have done an initial alignment before you can use NSOL.

ASPA is just the polar alignment function within the hand controller, it's not the initial alignment. ASPA relies on an initial alignment having been done first. You must always have done an initial alignment but the ASPA is totally optional.

The initial alignment (one star, two star, solar system align, Skyalign, etc.) is the key to using the Celestron NexStar firmware controlled mounts. That initial alignment is a very specialized routine that loads the motor controllers within the mount with the information required to accurately point to objects in the sky (perform gotos, track objects, etc.). Once the initial alignment has been successfully completed then a whole series of other functionality becomes available (the functions of the hand controller like the ASPA, or the capabilities within the scope control apps).
If you are running NexRemote and want to be able to more easily perform the initial alignment out at the scope consider using a game pad. The game pad gives you access to the buttons of NexRemote so you can sit at the eyepiece holding the game pad and perform the initial alignment with NexRemote running on a PC. You can also use the speech function within NexRemote so you don't even need to be able to see the PC's monitor. This all works best if the PC is at least in the general vicinity of the scope but it is technically possible to run NexRemote on a remote PC with audio and USB connections (for the game pad) at the scope.

One thing that many folks get caught up in is thinking that you need NexRemote to also run PC hosted planetarium or scope control apps (like CdC, Stellarium, The Sky, etc.) ... you don't. Unless you need some unique functionality of the hand controller (ASPA, Precise Goto, etc.) or the ability to perform the initial alignment remotely IMHO it's probably better to not bother with it.

Nexremote is a different piece of software from the Nexstar Control Pad. The Nexstar control pad can be downloaded at http://www.nexstarsi...m/Downloads.htm

Thanks for all the replies. I should had mentioned why i need ASPA. I dont have a physical view of polaris due to my house blocking itand some trees. Im going to try to set at the corner of my house which i believe i might see polaris but not sure how much area around it i can get. So if understand correctly i could to my regular ASPA with hand controller then fire up stellarium or other similar program that works with windows on my laptop and used that to control the gotos.
I have heard of other people using a mini pc and load all of the software to it and then remotely access everything via wifi from another computer. What would i need for this?
I would love to use skysafari but i don't think is windows based. I would have to use it with skyportal wifi adapter.

I also forgot to mention that on the cgem you have to do an aspa routine for the mount to start tracking. It won't track until this is done

No, this is absolutely not true. ASPA has nothing to do with when tracking starts. It does however affect how accurate the tracking is.

ASPA is not the initial alignment, it's just a built in polar alignment routine. I has nothing to do with external apps either. It guides the physical adjustment of the mount's latitude and azimuth adjustments ... it simple gets you a polar aligned mount, nothing more.

Initial alignment gets you a mount capable of gotos, and ready for attaching to an external app like Stellarium. Whether or not your mount is also polar aligned at this point is irrelevant (nice to have done but irrelevant).
