Cherry Spring:
- There are campsites, a Night Sky Public Viewing Area, and an Overnight Astronomy Observation Field. The gov't website also mentions "astro cabins" with their own star fields.
***********************************************************************
Overnight Astronomy Observation Field
"Overnight Astronomy Observation Field Fees: The single night base price for the Overnight Astronomy Observation Field will be $25 for each night. Patrons must visit the Contact Station in the Visitors Parking Lot to register for the Overnight Astronomy Observation Field. Patrons must comply with permit conditions and State Park Rules and Regulations including additional Overnight Astronomy Observation Field Rules.
Galaxy Pass: ***Discontinuing in 2026*** For a one-time fee you can have access to the Overnight Astronomy Observation Field for the rest of the year rather than paying the per night set-up fee. There are a limited number of passes available. The 2025 Galaxy Pass price is $200 and will expire on December 31st, 2025. Galaxy Pass users must still register at the contact station to document their stay and must comply with permit conditions and State Park Rules and Regulations including additional Overnight Astronomy Observation Field Rules. Patrons may purchase the Galaxy Pass by calling the Lyman Run State Park office at 814-435-5010 extension 6."
****Galaxy Pass and Overnight Fee Updates:**** Updated 25 February 2025 - Office Hours 8:00 AM - 4:00 PM - Due to limited office staff and increased call volumes, voicemails may not be answered in a timely manner.
Galaxy Passes are now available for sale. Limited quantities available. Galaxy Passes are for individuals and not for family units. Once purchased they will be available at the new contact station in the visitors parking lot. Galaxy Passes will not be mailed."

- The Overnight Astronomy Observation Field will be closed when it is filled. No “overflow” areas are permitted.
- Galaxy Pass holders must obtain and fully complete the required permit, including their assigned Galaxy Pass number before setting up on the Overnight Astronomy Observation Field.

- Winter Alert: "Cherry Springs State Park has reduced its services for winter operations. Visitors should be aware that the Cherry Springs Campground will close for the season on October 30th, 2024 and will reopen to the public on April 11th 2025. The comfort station, available on the Overnight Astronomy Observation field will close for the season on November 7th, 2024 as well as all water services will be shut down. Two vault latrine restrooms are available at Cherry Springs State Park, one restroom is available in the Visitor Parking Area and one at the backside of Overnight Astronomy Observation Field. All dumpsters are no longer available in the overnight areas, please follow "Carry In / Carry Out" guidelines; that is please carry out all trash you accumulate in the park.
Minimal winter maintenance allows for limited access to parking and observation areas. A small restroom on the back edge of the Overnight Astronomy Observation Field serves for both astronomers and snowmobilers. A small restroom is also located in the Visitor Parking Lot. Short Term star gazing can be conducted in the Night Sky Public Viewing Area on the north side of Route 44. Long Term star gazing can be performed on the south side of Route 44 in the Overnight Astronomy Observation Field. It is strongly recommended to let someone know where you are going, when you should return, and to maintain a cold weather survival kit. Astronomy Field regulations still apply; please review them prior to arrival. Please arrive well before dark for park familiarity."
- You do not have to stay at Cherry Springs campground to go to either the Night Sky Public Viewing Area, or the Overnight Astronomy Observation Field.
Night Sky Public Viewing Area:
From Reddit: "It was fairly crowded because it was a summer night. However, pretty much nonexistent light pollution. Folks were respectful of others stargazing (use red tape on flashlights). Also by 10-11, majority had left."
******************************************************************************************************
Astro Cabins?
https://cherryspringsstatepark.com/lodging/
every date I try says no availability. Didn't see a way to see a calendar so I could chose from available dates.
*******************************************************************************************************
VRBO
Some people says the whole area is dark, you don't need to go to Cherry Springs:
Check out this place I found on Vrbo! https://t.vrbo.io/p6jXtenypRb 4 brm sleeps 10. $825 for Mar 28-30 with 10 people, or $486 for only 4 people. There is a pasture and pavilion. People say just lay on the ground and look up at the sky.
**********************************************************************************************
Cherry Springs Rustic Campground:
- The Cherry Springs Rustic Campground is open mid-April through the late-October.
- There is a dirt berm which isolates the viewing areas from headlights.
- Your car's interior lights, and your phone and devices' screens, and your flashlight must be covered in red cellophane.
- Without light it will be so dark you will not be able to see the ground.
- It gets cold at night, even in the summer
https://cherryspringsstatepark.com/stargazing/
- Don’t give up on the stars too soon! Your eyes need 15 minutes to adjust for the full spectrum of stars.
Seeing conditions:
https://darksitefinder.com/map/
- Stars can be blurry even on a clear night because of temperature variations in different levels of air. Best time is midnight to dawn, after most heat has left.
- Twilight can brighten the sky about 1.5 hours before sunrise and 2 hours after sunset, so you want to avoid those times https://darksitefinder.com/how-to-see-the-milky-way/
- The milky way rises in the southeast, crosses the southern horizon, and then sets in the southwest. So you will want to choose a viewing site that does not have any major cities in that direction.
- A 1st quarter moon will set around midnight. So the hours after that will be dark. A 3rd quarter moon will rise around midnight, and the hours before that will be dark.

Camera Settings
- "Set focus to infinity (∞). You may need to use live view to zoom in on a bright star and really nail down the focus.
- Use the widest aperture on your lens or stop it down slightly. Set the exposure to 20-30 seconds, and use a high ISO such as 6400. This may need to be adjusted based on the darkness of your sky or the moon phase.
- Take off any filters and turn off shake reduction on your lens or camera.
- Make sure your tripod is secure and won’t blow over.
- Set the interval timer to take continuous exposures for at least a couple hours. Be sure to check it periodically to see if you need to swap batteries.
Gear
- "A camera that lets you take long exposures. High ISO sensitivity with low noise is a plus.
- An ultra-wide angle lens to take in as much sky as possible. Something like a Samyang 14mm f2.8 lens is an inexpensive option.
- A solid tripod
- Extra camera batteries, fully charged
- A memory card with plenty of space
- An interval timer. This may already be built into your camera.
- Hand warmers. In humid climates attaching these to your lens hood will help prevent dew or frost on the glass."
Bear proofing: I too camped at Lyman Run( great park) and the view from the park down by the lake and Cherry Springs are pretty much identical. I did both.Lots and lots of stars but the Milky Way is hard to make out. When I drove down to Cherry Springs I foolishly left my coolers out and when I returned they were scattered all over and had teeth marks in them and food was gone.I hope the bear liked my butter, eggs and steak
