I also have that one, it is OK, but the uplink port is one of those that easily becomes disconnected. I have everything in a self contained box, with cable ties on everything to prevent any movement. But power-wise (12V), and operability have been fine. Just don't expect it to run good if you hang it off your USB3 cables.

I'm using Astroberry btw, but I doubt it makes a difference.

This looks fantastic, is the only option to build one ourselves according to your plans, or can this be developed into a purchasable product?

With some focusers, when you purchase them you can sometimes choose a model which has a different USB id.

Like here for instance: www.firstlightoptics.com/astronomy-cable...ocus-controller.html

Note that there is the option at purchase to either buy "HitecAstro DC Focuser" or "Additional HitecAstro DC Focuser".

Quoting:
Existing Owners - Multiple Controllers
For existing Hitec DC Focus owners who wish to add a second controller to use alongside their existing one please select the 'Additional' option above.

This allows you to run a second controller in parallel with the existing controller on the same PC. In every other respect HitecDCFocus2 is exactly the same as the original.

Running two of exactly the same device from the same PC is not normally possible as the USB identifier would conflict and the PC would not know which one to talk to. HitecDCFocus2 contains a separate USB identifier so that they can be run side by side.

Just posted, and saw this thread below mine, seems like a very similar thought to my mine - I wasn't consciously aware of this thread when I wrote mine, perhaps I'd unconsciously seen it over the last couple of days!

Giles created a new topic ' Feature Idea - Platesolving Camera' in the forum. 3 weeks ago

Well, I'm on course for replacing my ASI120MC-S guide camera with an ASI290MM mini, which I will be putting on my OAG.

I've been thinking about what I could do with my ASI120MC-S, it does come with an all-sky fisheye lens, so I could dabble with that, whiling away the time through my 300s exposures, with some very wide field stuff.

Then, I came across a thought: When I am imaging, from the comfort of indoors, and the telescope out the back, I'm not immediately aware of clouds coming over. When clouds do appear, everything goes haywire - guiding goes out of control, focusing sends my focuser to the end of it's tether (literally) and it gets stuck there. Could I, somehow, use the ASI120MC-S, mounted to a small guide-scope piggy-backed on my main scope, to work as a plate-solving camera.

Plate Solve - If plate solving fails --> halt focusing and guiding activities
Plate Solve - If plate solving doesn't fit with location of imaging (with a threshold) - then, perhaps, at next main telescope exposure, schedule a re-alignment...

What are everybody's thoughts about this?

I know I could get a weather type station, or cloudwatcher, but just thought that this extra bit of kit might be useful.

This adds the "-C" for compression which helps with some things. I also had to use the "pi" account for some reason, probably to do with all my mucking around.

Just a note that using the native X protocol over the network can sometimes have very poor performance if the connection starts to have higher latencies. This is because the protocol is very laggy and a lot of things have to wait until the screen redraws complete.

If you're having problems with VNC, has anyone tried xrdp ?

XRDP is slightly different, in that it doesn't actually mirror the native desktop, but uses the MS Windows RDP protocol to run a new remote session on the Pi, but it might work better - so if multiple people were to connect they would each have a different desktop, although that isn't probably a good use case here, it still works with a single user.

When I am in my back garden. I run INDI server on the Pi4, with it connected via an Ethernet cable on my home network and I run Kstars and Ekos from the warmth of my house. All is powered via house AC via 12V regulated power supply.

I am planning on doing some remote astro in the future, at which point I would probably switch to using Kstars and Ekos on the Pi4.

The reasoning for this is that I can run the Pi4 off a battery, and conserve Laptop and Tablet power by only using VNC on the Laptop to set up and troubleshoot the scheduler session, and then only using VNC on the tablet to monitor the session progress, if an issue occurs I will bring the Laptop out of sleep mode, try and correct the issue and then revert back to the Tablet (View only). I can recharge the Tablet off the car adapter, don't have a recharge for the Laptop though, so would want to conserve its power as much as possible during the session.

Hoping that a PiJuice comes into stock soon, with a large battery, then I can use both the PiJuice battery and the Power Tank together to make sure that the Pi doesn't run out of power.

All while my camera is plugged in to USB3. This is great, I think that I've got a fix. I just need to install a VNC separate from X11/HDMI and I should be good to go. I can still VNC. but now just get a blank screen "can not currently show desktop". I verified that HDMI is not working by plugging it into a TV. No HDMI output.


I have HDMI turned off in /boot/config.txt by some option, maybe search power saving techniques to check exact directive, it does not stop VNC working just turns off HDMI hardware.

I have a question for you, since I did have this working well, but have since reinstalled Astroberry and setting up new settings for similar equipment.

Do you use the integrated USB2 hub on the ASI1600MM, or directly EFW / Guide devices to the Pi?

Also, do you use any specific bandwidth values for the cameras in the configuration?

This is interesting, as I think I've seen evidence of a recent glitch.

Need to try again before really reporting anything.

There does seem to be an increase in reporting of issues that might be related to mount perceived Lat/Long and Time settings.
