How one night at Cherry Springs State Park changed my mind about planetary nebulae, and why visual astronomy is a rare break from the task oriented world.

In short

• Bill McGeeney of Light Pollution News spent 2026 working through planetary nebulae, completing around 5 to 6 objects per night at Cherry Springs State Park in Pennsylvania.
• Finding that many objects takes 2 to 5 hours of star pattern matching with an unguided Dobsonian, which he calls a deliberate break from the task-oriented day-to-day world.
• He started from the Astronomical League’s Planetary Nebula program list.
• Cooler temperatures and early nights make autumn prime observing season.

We have no shortage of things to dissuade you from observing tonight. It may be too cold, the skies are hellishly bright these days, there’s no shortage of man-made objects in them, and all your neighbors seem to light up their properties as if they are a maximum-security arboretum. For all these challenges, it’s easy to get down on this hobby. It’s easy to feel that it’s just another burden that you don’t wish to inflict upon yourself. However, scarcity drives up value. And for that, the fact that you are still out observing acts as a beacon to others who may not truly know what brilliant arrangements can be seen at night.

How One Night at Cherry Springs State Park Changed My Mind About Planetary Nebulae

2026 became the year that I decided to dive into the planetary nebula rabbit hole. It’s not an easy one to do from home, so it’s almost exclusively a dark-sky activity for me. I’ll admit, when someone first mentioned planetary nebulae to me, my first thought was “you mean those tiny little dots?” After all, I’ve seen planetaries, many of which arrived at my eye via weeks-long photo observations from fellow astronomers. Finding these little guys just never seemed intriguing to me. Like most things in this hobby, your perspective seismically shifts the moment you witness things firsthand, by chance. And for me, it was a night at Cherry Springs State Park, tucked in the tree-carved corner away from the piercing car headlights.

That night started out like any other. I set up my photo rig. Then, I indulged in one of my favorite annual traditions, witnessing the spring galaxies cluster up in the western sky. At that point, it was pretty late, but I noticed my neighbor was still hastily scanning the sky. I walked over to see if I could catch a view through his 20-inch telescope. That’s when he began touring some of his favorite planetary nebulae.

As we viewed the sky, one by one, I became intrigued at the variety and personality of these little objects. They look like snowballs, sometimes dense, sometimes colorful. I expressed doubt that I could see these small dots with my telescope, to which he retorted, “Are you kidding, I found most of these objects using my 12-inch Dobsonian!”

Building a Planetary Nebula Observing List with the Astronomical League

Inspired, I walked back to my observing area on a mission. The next day, I woke up and downloaded the Astronomical League’s Planetary Nebula program list. Since I was working out of my iPad and was still quite a bit groggy from the night before, I asked Claude to organize the list by objects visible at zenith starting that night.

On my next trip to Cherry Springs, I fully dove in, completing around 5-6 objects per night. Mind you, I don’t have any guiding on my dob… which brings me to the second thesis of this paper.

Why Visual Astronomy Is a Break from the Task-Oriented World

Visual astronomy presents a very deliberate break from the task-oriented day-to-day world that we inhabit. When you’re searching for these little objects, you spend up to an hour immersed in star pattern matching, being sidetracked by interesting asterisms that only you will ever see, witnessing spectacular double stars that you’ll probably not ever return to, and richly appreciating parts of a constellation that you never knew could weave such a compelling journey. It’s no wonder astronomers like Herschel could spend their waking hours scanning endlessly on almost a daily basis.

Finding those 5-6 objects could take 2 hours, but they could also take 5 hours, packed with feelings of despair and hopelessness followed by awe and wonder, anchored in persistence. It’s impressive how wrapping your mind in a singular cocoon whisks away a lot of the stress that life caked atop your shoulders. Once removed, layer by layer, your curiosity takes hold and so does the internalization that the universe is infinitely larger than one could envision.

And maybe that’s the real reason behind my love of visual astronomy. Unlike other avenues of this hobby, the journey is on an equal footing with the destination. It’s as if you take 5-6 road trips in one night, each with their own memorable moments, stop-off vistas, and juicy burger joints. There’s no machine between you and the stars, you’re simply traversing the sea, exploring an endless crop of islands along the way.

Prime Observing Season Is Here

As we enter the prime observing season, with cooler temperatures and early nights, find some warm clothes, brew up some hot chocolate and indulge yourself in a voyage that few others have honestly taken.

Quick Answers About Hunting Planetary Nebulae

How many planetary nebulae can you find in one night of visual observing?

Bill McGeeney completes around 5 to 6 planetary nebulae per night at Cherry Springs State Park, observing visually with a Dobsonian that has no guiding. Finding that many can take anywhere from 2 to 5 hours.

Can you see planetary nebulae with a Dobsonian telescope?

Yes. At Cherry Springs State Park, a neighbor with a 20-inch telescope toured McGeeney through planetary nebulae and said he had found most of them with a 12-inch Dobsonian. McGeeney went on to find them with his own Dobsonian.

Where can I find a list of planetary nebulae to observe?

McGeeney started with the Astronomical League’s Planetary Nebula program list, then asked an AI assistant, Claude, to sort it by the objects visible at the zenith that night.

Can you hunt planetary nebulae from home?

McGeeney says it is not an easy pursuit from home, so for him it is almost exclusively a dark-sky activity, and he does it on trips to Cherry Springs State Park.

Why observe visually instead of photographing the sky?

McGeeney says that in visual astronomy the journey matters as much as the destination, and that there is no machine between you and the stars.
