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.

Horsehead nebula revisited

Since we are coming to the end of winter, I thought that I had better make full use of the opportunity to image the Horsehead nebula. Otherwise I may have to wait another 8-10 months before I can image it again. I was particularly keen to try imaging it with the Astronomik Deep Sky RGB filters and CLS-CCD filter. But I also did a few H-alpha images to see what it could add. Continue reading Horsehead nebula revisited
