It very rarely happens that we ‘ve got 9 nights in a row (around new Moon!) here in Belgium. Next to the main setup I have put the little SharpStar to use to capture- every night 10-minute frames of this area. Even with the Optolong LPS the large field gave a clear gradiënt of light pollution.
Seeing the tail appear after 145 frames made me smile 🙂 So yes it’s possible to capture this feature in SQM 20 type skies, you only need a lot of patience I guess (or a faster scope).
An overview image of Gemini around Messier 35, the well know open Star Cluster. The open cluster is on the top left, with very cloise on it’s upper right, the smalle open cluster NGC2158. Near the lower centre, we see the red gas of the ancient supernova remnant IC443, and to the upper right the bright hydrogen nebula IC2175. There are some spots in the image that I cannot define, maybe it’s reflections.
Click on the image for a better view, not sure why it looks so unsharp in this format!
A clear evening, just before the Moon appeared, allowed me to take some more images with the new TS76EDPH. What was really evident was how fast this scope is capturing the photons. A single frame on ISO800 with a Nikon D750, 300 seconds exposure, taken at about 50° above the horizon, would have a DSLR histogram peak about halfway.
