Backyard Nighttime Sky Over New Jersey.

It was a cold but clear night to try out a Vaonis Vespera Observation Station. This is a digital telescope, without an eyepiece for taking images of objects in the sky. The Vespera is controlled via Wi-Fi by the Singularity app. This allowed control the Vespera from inside a warm house. The Vespera automatically focuses the camera, and automatically tracks the selected object while taking a series of images (10 second exposures). The following image is of the Rosette Nebula (NGC2237-44). This is a composite of 309 images. The composite image was post-processed with Capture One Pro and Topaz Photo AI. I have also included a time-lapse video showing the development of the composite image by the Vespera. More images and comments about the Vespera to follow.
