Road Trip!
Get gas BEFORE you reach Route 44 Stock up at Wegman’s in Williamsport Fezz’s Community Diner in Sweden Valley is the bomb
but they only take cash Set up near an electrical outlet but be prepared to share No white lights, no laser pointers, minimal red light It can get very cold, very quickly. Dress warm and
bring anti-dew technology. WiFi password is DarkSky2015 The bathroom on the far side of the field is the worst
bathroom in Pennsylvania. Stick with the one near the road.
Shower at Lyman Run State Park.
Tips and Hacks
AstroTrac Mount
Nikon D7000
20, 35, 50, and 85mm lenses
Patience
What do I use?
ƒ4
ISO 800 - 1600
Shutter speed set to ‘B’
Exposure times from 2 to 10 minutes
How do I do it?
A 2 minute exposure under truly dark skies is not the same as a two minute exposure here
Use mirror lock up and a remote shutter release cable
Use prime lenses
Turn off autofocus
The higher the focal length, the more polar alignment counts
If you’re not polar aligning or tracking, keep exposures under 10 seconds
Post processing (e.g., Photoshop) is different than normal
