Solution for monitoring the telescope at night

Hello folks,

as many other users may do, I place my telescope during the night somewhere in my garden and let it run the whole time. Because I have a full time job, i need the sleep and can't be out with my equipment. I am always getting a bit nervous, if I leave the scope alone. It is not only the fact, that it can be stolen, but also the feeling to point it somewhere without a visual control what is happening. I once tried to use PEQ, but the mount behaves completly unexpected and I had good luck to be out before the camera can hit the tripod leg. So visual control is a must for my nerves.

I tried using a webcam to monitor what's going on, but the cam was made for daylight use and at night I only see black images. Maybe I plan to invest in a camera with IR light, so that I can see something in the dark. The problem with that is, that I don't have any idea, how the IR-Light might interfere with the imaging camera and how it affects the taken subs.

Does anyone have experiences with such solutions and can share them with me/us? Are there maybe other simple solutions I haven't thought of yet? I plan to build my own remotely controled observatory one day and the solution will be part of the plan.

Thanks for your help…

Hi Christian,

I also like to have the opportunity to take a look at what’s going on in the garden (where the scope is) to be sure that everything worked as planned. I‘ve purchased a cheap surveillance camera with IR. 
Since I haven’t been imagining in the IR spectrum, I don‘t know if it will have visible effects there but for the rest, it’s absolutely no problem.

Best,
Björn

I don't get it. To watch it, remotely or otherwise, you'd need to be awake therefore what would be the point? And yes, if you shine iR light right at the scope aperture you might get weird effects unless you have a rock solid IR cut filter somewhere.

Personally I use an "Eufy" camera. It's actually one for indoor use. But.. given the nature of the hobby, and needing nice weather anyway. It so far has worked just fine (Not sure about Dew when the weather gets a bit colder)

There are loads of different options available, I went for Eufy as it comes without any further cost to run it & store data.
And allows me to live stream the view to my iPad. 

Anyway, So far I've been using it next to my colour scope, with an Optolong L-Extreme filter. And I couldn't see any difference in the images with the security camera (IR mode) turned on or off (with 5 minute exposure). So, I don't know if it simply doesn't affect it, or if the Optolong filter blocks the IR light. Or the IR is so dim, that it doesn't affect it. I also didn't really see any difference in guiding (And that's unfiltered on my scope). So, I thought it would affect it, but (at least so far) I haven't had any issue.

But, I haven't been pointing the camera straight into the scope, and always place it behind/below the scope, to never shine straight down the tube.




As for the hitting of the tripod, looking at the equipment listed on your images, I see you're using an EQ6? 
Skywatcher sells a "pier extension" to be placed on the EQ6 R tripod. This raises your mount/scope by 22cm. 
The increased height (without being any wider) means that hitting a tripod leg almost becomes impossible, which should give you some more sleep at night.
This might be a very easy way (and quite a cheap way) to prevent this from happening.

Hope this helps!

I also set things up, start imaging, then go to bed, and I’ve even resisted getting a battery adapter for my camera just so that I have to get up a couple of times to change the battery and check things out at the same time. Still, occasionally something goes awry and I’ll lose a night of imaging but what I really fear is that it’ll start raining, no matter how clear it was when I started….need to connect phd2 to an alarm in my bedroom somehow!

Cheers,
Scott

Hello again. Thank you for your answers.

@andrea tasselli 
Of course, I have to be awake to look for the scope. But it is a difference to get up and walk outside (which is quite far in my case) or to have a short look at the laptop monitor, that is placed next to my bed. The difference is about 3 minutes. And if you step out in the cold night, it is quite hard to fall asleep again.

@Björn Arnold  and @Steven de Vet 
It is nice to hear, that the IR light does not effect the exposures much. Most of the times, I use my narrowband filters for imaging. I guess, with them the effect is negligable. I fear a bit about the LRGB set, especially with the L and the R filter. I may trust in the quality of the Astronomik filters I use. Also the camera must not be active the whole night and I will turn it on only occasionally.
I also know about this extension tube. Thank you for the suggestion. But worry a bit about stability. I solved the problem in software and set some borders in the EQMOD software at some place. Also, I monitor the current of the mount with a raspberry pi. In case, the motors draw too much current, the power will be disconnected automatically using a relay. I hope, this will save my equipment at some point.

@Scott Badger 
It happened to me, that I woke up and there was heavy rain out there. The scope was really wet. There was a lot of electronics on the scope, that I feared about. But I set up all the equipment with a bit of outdoor use in mind and everything survived the shower. I placed the imaging laptop and all the dc converters for the different power requirements in a single case and I place this under my mount (having all the stuff in one case minimizes setup time immensely). I close the cover of the case as far as I can and put a plastic bag above it (just in case). The connectors are placed on the side of the case and I always look for the cables to go down to the floor at first, before they rise up to the mount and the scope. Doing so, the rain will always drop down to the floor and the water is not flowing into the connectors or the case. The control of the imaging laptop is done via remote access from my bedroom. This way, I feel quite safe.
But this adventure made me buy a HitecAstro Weather deluxe box. It is not the cheapest solution and I realized, that the software is a bit out of date, but it warns me if there are clouds or rain, can log the sky quality and controls the ascom safety monitor (only 32Bit mode). The thresholds are fully customizable and the alarm tone sounds really bad .

So thanks again

Hi Christian,

I take similar precautions with the ancillary electronics and not too worried about the scope, but the mount is my biggest concern being the most exposed. I'll take a look at the HiteAstro Weather box, but figured phd2 is a pretty good sensor for clouds (at least where you're pointing) and already has a really annoying alarm!….: )

Cheers,
Scott

I second the Eufy camera solution. Mine is mounted on the end of my roll-off roof, so the telescope is in the field of view even when the observatory is open.  Of course, you dont need an observatory as the camera is very portable and easily attachable.

Mine was specifically designed for outdoor use and runs for a year on one charge.  I have been running it for a year with no problems at all.

No impact on subs, reliable use and it can be run from an app on your phone. Also good for monitoring those tricky automated meridian flips.

Thanks Brian,

I am looking for a similar solution like the Eufys but may buy a camera with a lan port. I don't worry about cables to my scope and the equipment. The only thing I do worry about is the WLAN access. I try to keep things on wired solutions. This is more reliable in my experience. I have some plans to build the observatory step by step and the upcoming solutions are all based on those ideas in my head. Also the decitions about new equipment are influenced that way.

Hi Christian,  Fair enough.  I did like eufy because all the data is stored locally and not on some anonymous cloud.  But it definitely uses WLAN.  My only comment would be it these, I don't really notice any WLAN issues when I have both my 6200MM and 2400MC going in tandem (plus any traffic from the eufy camera) using google wifi hubs to extend my WLAN.

I've just bought a cheap TP-link Tapo C200 wifi security camera for the same purpose. No clear nights to try it in action yet but I've tested it out and it looks like it will work as planned. I can monitor it either from my phone or the free s/w Ispy running on my Windows PC.  I did check out the wavelength used by security cameras and, if I recall correctly, it is in the 800 to 900 nm band. The QE curves for my QHY cameras show they are sensitive out  to that region but in practice I will always be using a filter - e.g. a UV/IR cut filter on my OSC cameras or a NB or LRGB filter on mono -  which will cut off that region, so in theory there should be no impact. I don't see how the camera can help avoid pier/tripod collisions - well, not if your sound asleep. That is down to careful planning and whatever tools are available in software (e.g. mount limits in EQMOD).
Cheers

Hello Brian,

I do not care about issues with the equipment itself and that it could be affected be the signal. It is just the connection to my Router, that is not reliable. The scope is too far away. I also cannot use the WLAN of the imaging Laptop as an access point, because it is placed in an at night closed metal case and the connection is also not reliable. Also I am used to the speed of the Gigabit LAN. The cables are no problem and I am safe.

@John Sim 
I do not say that it is safe in all ways, but I may react much faster

Stay away from IR cameras, they bleed into your frames possibly ruining your nights worth of imaging. It depends on how close the light is to your scope and how bright it is of course.

If you are worried about the camera getting stuck on the tripod leg or the mount itself (it has happened to me a few times!), an outlet timer may be of help. Set it to turn off the power to your rig just before the camera hits the tripod. It's not that difficult to figure out at what time during the night that'll happen, and just to be safe you can set it to cut off a bit sooner (like 30 minutes or so).

I don’t have a permanent set up yet but I do leave my tripod and mount covered outside and just ran into a problem I hadn’t considered… Bees making mud nests in the connection ports!….

The hitting the tripod is the least problem. I'm using Raspberry Pi4b on the fastened on the OTA to control everything on the rig. Using the Ekos Object and Sequence Selection you can program most things that might happen. In addition I can set force Park at a certain time and make Meridian flip when needed. The mount itself also has physical stops. If the worst should happen and you hit the tripod, the stepping motors makes a hell of a noise. You might mount a microphone and a loudspeaker by the bed. It will certainly wake you up!

The worst would be a unpredicted rainfall! I would really like to have a weather station and an alarm connected to it!
