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.

Rosette nebula – Samyang 135mm F2 + narrow band filters

On Valentine’s day I did post a picture of the Rosette nebula. What I did not tell you was that it was imaged using the Samyang 135mm F2 lens and my Astronomik narrowband filters (specifically H-alpha and O-III). That final photo was a result of 5 x 5min H-alpha images making up the red channel and 14 x 5min O-III images making up both the blue and green channels. I used the gain setting of 100 (19% gain) on the ZWO ASI178MM-cooled, and sensor temperature at -25 degrees celsius. Continue reading Rosette nebula – Samyang 135mm F2 + narrow band filters

Valentine’s Day

Happy Valentine’s day to everyone. The photo of the day is dedicated to my wife, mother and sister, who are all over 6,000 miles away from England. So it is only fitting to send them this picture of the Rosette nebula, so named as it resembles a rose which I have portrayed in red. It is worth noting that this nebula is some 5,000 light years away from earth, symbolic of when your loved ones are ‘light-years’ away. Continue reading Valentine’s Day
