Backyard Nighttime Sky Over New Jersey.

It’s the winter solstice (or the longest night). Early in the morning I captured images of the Andromeda Galaxy (M31) using the mosaic mode for a wider field of view (400 images). Also, the Horsehead Nebula (B33). Although I collected 1107 images, I could only use the first 379 images for the composite because a Sycamore tree blocks the view towards the west. Early evening, I captured images of the Dumbbell Nebula (M27). I had to stop after 258 images because the sky started to cloud over. No more observations for a couple of days due to the forecast of a winter storm.

One thing that I don’t like about the Vespera is the data needs to be transferred via WiFi using ftp to a PC. There isn’t a removable data card or USB cable option for the data transfer.

Vespera Deep Sky Observations. Individual images in the slideshow are available in my PhotoShelter Gallery.

Daily Electric Energy Used (99.6 kWh) from Sense. Daily Solar Electric Energy Produced (30.8 kWh) from Sense. Sunny. Deficit of 68.8 kWh. I should note that on a sunny day near the Summer Solstice the solar panels produce 3 times as much power. Longer hours and the sun is higher in the sky.
