In the evening of September 27th, a Centaur rocket burned it’s upper stage for a de-orbit. The resulting exhaust plume showed up on the all-sky camera. Very very low in the North (top side of the frame) there are three frames that captured it while going north, disappearing below the horizon.
A little Seahorse in the sky
This is an image of “Barnard 150”, a dark cloud of dust and gas that becomes visible aginst the majestic backdrop of milky way stars and nebulosity. When you turn the image 90° CW then the shape resembles a little seahorse, turning it’s head to the right.
The image was made during two nights 7 and 8 September 2021, using the SharpStar 76mm @ F4,5 and the ASI2600mc, 201x120s or 402 minutes (about 8 hours) under a less-then-optimal sky, bad transparency and sqm 20 so Bortle class 5 or 6 sky.

A Cepheus Jewel box: Cave Nebula
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.
