The primary advantage of observing at Green Lane is its proximity to home for the majority of DVAA club members. There are good horizons in most directions, particularly to the south and the west/northwest. On a representative night, the limiting magnitude was estimated to be around 5.7 or 5.8. Globular clusters, open clusters, and nebulae which respond well to filters could be observed, except for those at low altitude where the skyglow is prevalent.
This site is approximately 40 minutes drive from Radnor, in a field adjacent to the parking lot for the Green Lane Park Red Trail. From Rt 29 North, turn left on Knight Road, then proceed a few hundred feet and turn left into the gravel parking area. An address for your GPS app which will bring you close to the field is 1102 Gravel Pike, Green Lane, PA 18054.
Directions.
DVAA members are allowed to observe without a permit only at the Red Trail parking spot off Knight Road. All other locations in the park are prohibited after sunset. The location near the amphitheater (formerly used for observing) is no longer appropriate due to a change in the lighting conditions. A police officer may stop to ask you questions, but they have gotten use to us being there and are very friendly.
The parking lot is not paved; it's uneven in places so it is wise to drive slowly and arrive well before sunset. The field is also a staging area for horseback riders so it's important to watch your step. This link shows the entrance to the parking area, and the observing area which is behind the stand of trees. Parking area and observing field. There is a PortaPotty adjacent to the trail which is usually unlocked.
