A surprisingly dynamic region in Cepheus, the Cave nebula and surroundings. This image was taken during 4 nights with the little 76mm refractor at F4,5, with the ASI2600MC camera and an IR/UV cutoff filter. Total imaging time almost 18 hours, in subs of two minutes.
Image with the ASI2600MC camera, cooled to -10°C, and the SharpStar 76EDPH at F 4.5, IDAS D1 LPS filter, 138x300s or 690 minutes of data at Gain 100. (Click on the image to enlarge)
One of my favorite objects, IC1396 in Cepheus, or also called the “Elephant Trunc”, imaged from Castellet-en-Luberon under a beautifull SQM 21.30 sky, with crickets, shooting stars.
