Tonite I made some mount experiments and wanted to go home... But suddenly clear sky was above so I switched the camera and telescope on again and right now I am performing some unfiltered observation of the IGR[9] field. It's quite suitable run, lookin' fward to examine combined images... I made also VRI short serie to get some color info about the bright objects and extinction artefacts...

Preview of the combined image of IGR [9] filed in Clear.

And here it is. Flatfielded & combined more than 200 minutes. Limitting magnitude is really low...

No clear sources of noise were detected. But there are uncertain stars there ;)
