Deep Sky RGB filter – Pleiades and Rosette nebula

In the recent months, each time when there was clear skies, there seemed to be the moon prominently lighting up the night sky. Hence the only form of imaging I could do was with narrowband filters. But recently there were a few reasonably clear nights without the moon lighting up the sky. So even though the light pollution was higher than it normally is, I decided that I still had to take the opportunity to try out the Astronomik Deep Sky RGB filters for imaging.

ZWO ASI178MM-cooled – UV imaging (part 2)

Having tested the ZWO ASI178MM-cooled for UV imaging, and found that it is very capable for such invisible band imaging, I decided to take it to the next level of testing to see what are the limits to its capabilities. My subject is the more well known Dandelion flower which I had picked from my back garden. This flower has been imaged many times in UV, so it is sort of a reference flower for UV imaging.

Solar H-alpha imaging – ZWO ASI178MM-cooled (update)

Since the last attempt at solar H-alpha imaging with the Daystar Quark and ZWO ASI178MM-cooled, I have been looking for the opportunity again to image the sun. I had previously encountered Newton rings, suggesting that the camera was not aligned properly with the Daystar Quark. So there were a few things I wanted to try. Sunday 7/2/16 gave me the perfect opportunity, as the skies cleared long enough for me to do some imaging. And the sun had many features to image as well.
