Remote imaging, from very dark sites, seems to be the thing anymore. You pay the monthly fee, someone manages the gear (yours or theirs), gathers the data from very expensive scopes/mounts and sends it to you in the morning. Seems pretty cool and can result in fantastic images. I hear the best part is having a full sleep each night…..

I still do it the “old fashion” way. Prepare for the target, open my observatory, push all the buttons, make sure it’s all running as needed and wait for the moment to hit the start button. I often sit outside under the stars for hours and hours watching my telescope and computers gather data. For me its fascinating and often very rewarding, knowing I had the equipment and smarts to gather all the images myself, with my gear and my brain power.

Sometimes it is very cold, sometimes it is beyond frustrating and sometimes it is absolute magic for me. Something about building the entire systems myself, preparing the hardware and processes to gather light of millions of light years away.

I can surely “afford” a remote scope, set up anywhere in the world, but doing it the old fashion way is fulfilling and keeps the brain in top shape.

For those who use remote sites, good for you, I love your images. For the those gathering images from your own backyard and some dark site you had to drive to and set up your gear; YOU have my respect . Something about hands-on processes make it worthwhile in the end.

Thank you, pray for clear skies.

The calculus here in Ireland is simple. We are lucky to get 1 clear night a month. Many here have now switched to remote in Spain etc as result.
We have not had a fully clear night here since early October..
I used to be very much in the hand-on camp but the more I get into the hobby, the more appealing a remote setup becomes. Projects requiring very long integration might take many years as by the time another clear night comes, the target is no longer visible. Cost is the only factor for me really.

The only difference I find between hosting my equipment remotely vs in my backyard is that once provisioned (which takes months to iron out all the glitches) is that when you need to swap a usb cable or something you open a ticket instead of walking out there and doing it yourself.   But by this time that hardly happens, right?

Here's the thing though:

You still decide the equipment you want to use and how you want to configure it.    You choose the components, you decide the tradeoffs, you test their performance in your back yard, maybe you change your mind and try something else until you converge on a setup that does what you want.   Then you test the heck out of in your backyard for a few months and once it's been running well without constant attention, you package it up and take it to a remote observatory.

At most remote observatories you then reassemble your system on the pier you're leasing.  You generally stay a few nights to be sure it's all working well in its new home, and then you go home.

Once back home you use the same computer to control it in the same way as when it was in your backyard but the difference being now you're getting fantastic data from a B1 site and producing images you could never do in your B7+ backyard.

Once in a while something goes wrong (hopefully minor) and you open a ticket for a tech to swap it out for you.   Maybe you need a new USB cable, maybe your filter wheel isn't always rotating correctly, etc.   You buy the new replacements and send it to the remote observatory and the tech installs it for you.  But if you're smart (and I know you are) you give extremely detailed instructions in the ticket describing exactly how you would do the work yourself.  

It's 95% the same as doing it all yourself and for that 5% loss of control you get crazy good data, plus you pay your monthly pier rental fee.

In my 18 months of hosting my Esprit 100 at Starfront I've found this to be a very good trade off.

I have many remote setups, one of them is in my own garden.

Except a few maintenance things, it is exactly the same as controlling the telescope in Namibia remotely - except for better seeing, more darkness and far less clouds.

My 2 cents:

Astrophotography today offers different paths, and each of them has its own value. Remote telescopes are an extraordinary tool: they give access to pristine skies, advanced instruments, and data that would otherwise be unreachable for many people. They democratize astrophotography and push its technical and scientific potential further than ever before.

At the same time, traveling to dark skies, setting up your own gear, and spending the night under the stars is a completely different experience. It is slower, less efficient, and often more demanding. But it is also deeply human. The drive into the darkness, the quiet moments while polar aligning, the cold air, the sound of the wind, the Milky Way rising above you. You are not just collecting photons, you are living the night.

For me, this is where the poetry of astrophotography truly resides. The final image carries the memory of that place and that moment. It reflects the patience, the waiting, the small struggles, and the awe of standing beneath an immense sky. Traditional astrophotography is not only about results, but about presence, connection, and wonder.

Both approaches can coexist and inspire us in different ways. But while remote astrophotography shows us the universe, being under the stars reminds us why we fell in love with it in the first place.

And last… I’ve got a lot of astrophotography friends… Love to spend nights together with them under the stars! We have a lot of fun! 😀

The absence of tactile connection to my data is why I choose not to do remote, even though the weather here, as in Ireland, is far from ideal. In addition to cloudy weather, we have to contend with extreme cold (currently -20 C here) during winter and smoke during a large portion of summer.

Well, I’m a taint. 🤔

My equipment is in my backyard. But the remoteness is about 75 feet via Wi-Fi. I can, and have to, be hands on, but nobody covers or uncovers my equipment, and when a software glitch occurs it’s me, myself, and I who attends to it. Like right now ASTAP is being bratty, so I’m dealing with that.

Keeps the gray matter twitching.

Sometimes I will sit out with my gear and look up and listen to the night critters. But I can choose.

Taint far away, Taint makin me sit out in the cold and babysit. I can choose,,,

And I choose to use the equipment I want to use. At least my wife doesn’t feel like a golf widow.

I was just having this conversation with my wife yesterday. We live in Texas and I could send all of my scopes down to Big Bend rather "cheaply" and capture incredible data. It's just not for me. 

For me it comes down to probably 3 usage scenarios, those that like to tinker with things and need their equipment at home, those that live in areas that are challenged with good weather/dark skies and need a remote site, and those that are purely into creating images with data and don't care about the fuss of capturing images.

My $0.02 worth, is that if you have gone to the trouble of building an actual backyard observatory, there really is no difference to a remote observatory (assuming using your own equipment in each case). The difference is your “backyard" is now thousand(s) of miles away. I have a tandem setup so I can do wide field as well as long fl imaging so I don't need to change setups…but that was the case in my own backyard as well.

I personally took my equipment to HCRO and set it up myself, just like in my backyard. I run it just like it was in my backyard. I frequently monitor it during the night’s imaging run…just like when it was in my backyard.

Now if you are setting up a tearing down every night or with some frequency due to being able to leave it in the backyard covered from time to time. Taking it to a remote site occasionally to get better conditions…that is an entirely different animal and I've been there, done that.

If you are just buying data…to each their own I say.

Not sure if it’s much a public debate (other than those stirring the pot) than a personal one. It’s as much of debate as whether looking through the eyepiece is “better” than astrophotography.

We’re in this hobby for personal reasons, and those reasons aren’t usually static. I think we all want to learn and grow. Some enjoy tinkering with equipment, some enjoy the challenge of post-processing and watching your hard-collected data turn into something amazing.

I started this journey over 25 years ago, starting with a film camera and hand-guiding, then gluing a film canister onto a webcam and removing the lens to capture Saturn and Jupiter, a-focal photography with the first digital cameras, being on the forefront of using the first DSLRs to capture amazing deep images (at the time) and then to cooled SBIG and Starlight Xpress cooled cameras. Every one of those steps felt like “cheating” but helped move me and the community forward.

I dropped out for 18 years with kids and other priorities and just got back in a few years ago. The so-called “cheating” has continued with amazing software and so much less expensive and capable cameras. What was considered almost unattainable 20 years ago can be surpassed by a beginner with a (relatively) modest investment today.

Look at images of the day from 5 years ago here…many wouldn’t be special at all today. Remote imaging has furthered this hobby probably more and faster than most other innovations. People can routinely collect dozens of hours of photons in a week, which would have taken many years for most people before.

But we just all have to realize it’s not the end that makes most people stay in this hobby, it the process. Otherwise, we could just download Hubble or JWST data and process it (which some people do and enjoy as well). Some like to see how far they can push modest equipment, some want the equipment to get out of the way so they can efficiently collect data. Some take great pride in building their own telescopes or modding various pieces of equipment.

Some wish for clearer skies, some decide they can do something about that.

On the flip side John, if something is scarce it makes it more valuable.

Did Backyard imaging for two years. Its fun but you can only image so many narrowband targets from B7 that is now becoming B8 and worsening. About the only broadband target that you can image are bright galaxies and very bright nebulae like Orion. Beyond that it was a slugfest.

I have two remote setups now. Both setups are things that I have personally used in my backyard for months before setting them up remotely. Depends on where you send your remote setup, you can personally take your equipment, set it up yourself, and just use the onsite staff for troubleshooting any issues that come up. It is still very hands on IMO. It never works smoothly and 99% of the time, if there is a problem, you need to figure it out and fix it and give the instructions to the onsite tech. In some ways it is harder than backyard imaging.

When I was doing backyard astrophotography, I had my setup essentially outdoors covered for months on end, and all I did was turn it on, uncover the scope and run in the office to start the process. Hardly any different remotely.

I still do planetary imaging and visual from home. Gives me enough things to do and play with.

To each their own, but remote imaging has extended my enjoyment of AP significantly.

If I take a little peek into the future where I can imagine time when it will be possible for small groups to pool the funds to build and launch a small telescope into space. The remote Earth based hosting sites will be long gone, space will be where all the award winning images will come from.

I can also imagine that as that Starfront 16” wizzes by overhead I’ll be in my back garden, preparing my now “quaint” setup to do battle with clouds, mists, jet streams, neighbors porch light and that pesky 16” as it photobombs my sensor. I have the feeling it will still make me smile.

Yes, imaging under B7-B8 does present challenges for broadband. I’m in the same boat and if cost wasn’t a concern, I’d probably have at least one rig at a remote site. At this point, I can’t justify the monthly fee.

Hi Tony,

This was in the making back in 2011 - 2013 but never was finished ¿?. I personally knew Heiko Wilkens and the idea came up during his visit to Mexico where we spoke about this.

Make a search with the words “heiko wilkens telescope in space”

Below the link to one article of many about this project

He even got funds from European governments. I tried to contact him a few years ago and it is just like the Earth swallowed him. He was a good friend of me until he disappeared 🤔 I even contacted one of his project associates (Mr. Christian Wiederer) and he also told me he does not know where he is. 🧐

He was also the developper of the Lucam Recorder software for the LUMENERA cameras (mainly Microscopy use) as well as The Imaging Source cameras which nowadays of course are obsolete due to the many different good chinese cameras.

The company Astrofactum GmbH disappeared mid 2018 and ended in 2019.

May I ask in regard to this topic …

What is the main reason or what drives us for going remote, and with remote I mean a few hundreds to thousand km/miles away from our backyard?

🤔

That’s really interesting Rainer, I’ll certainly have a look at all that.

My thinking is that if Starship or something like it is the way forward, costs will come down enough to make privately owned space telescopes a possibility.

For me, it would be to image far away from city light pollution. I don’t have the option to goto dark sites, so that would be my main reason.

Since it’s still too costly in my scenario, I have to work with what I have.

Main reason? Atmospheric conditions from weather to light pollution and seeing. All factored heavily in my decision.

I guess it will still stay in the 6 digit figure $$$$$$. OK, some people already have on Earth 7 digit set ups 😎 and if I take what I invested in MXN $ Pesos then I am in the 7 digit figure 🤣

I run a remote observatory using ROR observatory hosted by my local astronomy club, about 3 hours away from my home. Each unit is about 3.6 m × 3 m and comes with only the basics: a finished floor, walls, and a simple garage-door opener mechanism to open and close the roof. Everything beyond that is entirely up to the individual user.

People use these observatories in very different ways. Some use them as a simple warm room to rest in during cold desert mornings. Others use them purely as storage for equipment. Some install telescopes but do not operate them remotely. The majority, however, set them up as fully remote imaging observatories. A nearby university even rents two of them specifically for asteroid-tracking projects.

The key point is that all setup and customization is the responsibility of each user. In my case, when I first received the observatory, there was no pier and no anchor bolts in the floor. I had to drill into the concrete, install bolts, design and build the pier, cut and fit materials, mount the telescope and imaging train, and then install all observatory cameras, observatory sensors, and monitoring systems myself.

I also built a full automation and safety system. Using Home Assistant and Rasberry Pi, I configured automatic roof control, including emergency roof closure using backup batteries during power outages, automatic closure when rain or clouds are detected by sensors, and automatic closure if the internet connection is lost. All of this had to be designed, wired, programmed, and tested on my own.

Even after the initial setup was complete, ongoing maintenance has been frequent. Sensors sometimes stop responding, cameras or mounts lose connection, or software issues appear that can only be resolved on site. These problems happen more often than I originally expected, and they require me to physically drive to the observatory to fix them.

At first, I assumed that once a remote observatory was fully set up, everything could be done from home. In reality, after building a remote observatory, I now find myself driving to the site—about three hours away—more often than before. Surprisingly, though, I genuinely enjoy this process. Building, troubleshooting, improving, and maintaining the remote observatory has become a major part of the fun, not just the imaging itself.
