McKinney: The Practical Verdict
McKinney is a small city in Texas, surrounded by Dallas's considerable light dome to the south-south-west. The sky is severely affected by urban brightness, offering limited stargazing opportunities. Studying the night sky here is largely constrained to the brightest celestial objects.
The true Milky Way is absent, with effective observing limited to the Moon, planets, and bright stars. Some astrophotography with narrowband filters on bright nebulae is possible, but broad deep-sky imaging will be hampered significantly by sky brightness. Deep-sky targets like faint nebulae should be avoided.
For darker skies, a site approximately 150 km north-west offers a meaningful upgrade. Heading out there would allow for serious deep-sky observing, moving beyond the limits posed by McKinney's intense light pollution.
At a Glance
- Overall
- Severe urban sky - This is a severely light-polluted urban sky. Only the Moon, planets, bright stars, and a few specialist targets remain practical.
- Milky Way
- Not visible - The Milky Way is not visible from this sky.
- Best targets from here
- Moon, planets, bright stars, double stars, solar system events, narrowband imaging only with care
- Do not prioritise
- visual deep-sky observing, broadband galaxies, reflection nebulae, widefield Milky Way
- Best nearby upgrade
- 150 km NW sits about 150 km north west and reaches Bortle 4, roughly 21x darker.
- Good dark window
- McKinney's longest dark windows fall in December and January, with the shortest nights around June and July. Plan deep-sky sessions around the autumn and winter months for the best combination of long nights and true astronomical darkness.
Frequently Asked Questions
Can you see the Milky Way from McKinney?
No. McKinney is a Bortle Class 9 sky with SQM 17.59, so the Milky Way is not visible from the city. For Milky Way photography, look for a Bortle 4 or darker site.
What Bortle class is McKinney?
McKinney is Bortle Class 9 (SQM 17.59), a severe urban sky for astronomy.
Is McKinney good for stargazing?
Not for serious deep-sky observing. McKinney is a severe urban sky where the Moon, planets, and a handful of bright targets are the realistic options from the city itself.
Is McKinney good for astrophotography?
Broadband deep-sky imaging is heavily compromised from McKinney and a Bortle 4 or darker site is strongly recommended. Even narrowband imaging is difficult from McKinney without careful processing.
What can you observe from McKinney?
Primary targets from McKinney include Moon, planets, bright stars, double stars, solar system events. Targets such as visual deep-sky observing, broadband galaxies, reflection nebulae are not realistic from this sky.
Where are darker skies near McKinney?
The closest meaningfully darker mapped site is 24 km E, about 24 km east of McKinney, reaching Bortle 7.
When is the sky darkest in McKinney?
The sky over McKinney is darkest around January, December.
Is light pollution in McKinney getting better or worse?
Long-term light pollution over McKinney has been broadly stable across the available measurements.
north - fair
The north sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.
north-north-east - fair
A faint diffuse glow on the north-north-east horizon. Stars are visible to low elevation, with minor losses near the ground.
north-east - fair
A faint diffuse glow on the north-east horizon. Stars are visible to low elevation, with minor losses near the ground.
east-north-east - fair
A faint diffuse glow on the east-north-east horizon. Stars are visible to low elevation, with minor losses near the ground.
east - fair
The east sky is broadly dark with a small amount of glow at the horizon. Most objects in this direction are accessible.
east-south-east - fair
A trace of skyglow near the east-south-east horizon. Stars are clear throughout this direction except very close to the ground.
south-east - fair
A trace of skyglow near the south-east horizon. Stars are clear throughout this direction except very close to the ground.
south-south-east - marginal
Noticeable glow on the south-south-east horizon. Stars below about 20 degrees in this direction are dimmed.
south - marginal
The south sky shows a clear glow near the ground. Above about 20 degrees the sky returns to workable.
south-south-west - poor
Heavy light pollution to the south-south-west. The lower 30 degrees of sky in this direction are unusable for faint targets.
south-west - poor
The south-west sky is washed out near the horizon. Most constellation stars in the lower sky here are not visible.
west-south-west - poor
The west-south-west horizon shows a strong orange-white glow. Star counts drop sharply below about 25 degrees here.
west - marginal
The west sky shows a clear glow near the ground. Above about 20 degrees the sky returns to workable.
west-north-west - marginal
Soft skyglow visible on the west-north-west horizon. Mid-brightness stars survive at low elevation; the faintest do not.
north-west - marginal
The north-west lower sky is measurably brighter than the darker quarters. Limit faint work to above about 20 degrees here.
north-north-west - fair
Light glow detectable on the north-north-west horizon. The effect fades quickly with elevation and does not affect overhead work.
zenith - poor
The zenith sky is bright. The Milky Way is absent and most constellation stars are not visible.
