Details:
After what seemed like weeks of cloudy nights in SE PA, the sky cleared. Since it was too windy to setup the dob, I took the camera out and setup between the cars. Temps around 30F with winds 10-15mph. Limiting mag was a little more than 4, which is average in my light polluted sky.
Details: Nikon - D5500 and 200mm AiS MF f4 with a Hoya red intensifier filter (poor mans light pollution filter). An iOptron SkyTracker Pro was used for tracking. 50x20sec lights (f8) and 30 darks - 400iso. Shutter was controlled with a homemade IR trigger and an iPhone using DSLR.bot. Raws converted to TIF w/ViewNX2 and stacked with Regim (v3.4). Image stretched with rnc-color-stretch (ClarkVision.com) and further processed with AffinityPhoto.
