My image gallery is currently off-line and images are not available or visible in posts. I’m working on to solve the problem.

The Rosette Nebula

Last night I was able to image RGB-data for Rosette and here is the result.

The Rosette Nebula

This is my very first image of Rosette Nebula. This image was taken by automated imaging session where CCDCommander was controlling my dome, mount, focuser, cloud sensor and two CCD cameras. Everything went well and this is just one of my targets from last night. Total length of my automated imaging session was 10 hours!! How great is that!

I will continue to image this great nebula and will add the results here when available. Image details available here.

17P/Holmes LRGB

I found some ‘lost’ images of comet Holmes taken on 4.11. This is a LRGB image made of those ‘lost’ images. The tail is visible and have some nice blue color.
