Hello everyone. I do not know how to pull off the most troublesome spots and Mother House! 20140928_131630.jpg As you can see from the above sunspots there are circular spots of dirt. This thing comes out only and exclusively when I use the Barlow. I took a Q-and, wrapped in a microfiber cloth, I cleaned and breathed in a circular motion on: CCD, IR Filters, Barlow lens speriore and bottom. None of this helped. Perci I wonder if the problem is not on the secondary mirror. Can you help me please? I have a Celestron LCM 114 Barlowato, a CCD imager Omegon solr system and a 2x Barlow celestro x-cell. Thanks
Hello Michael, this is a problem we have a little 'all including myself, I do so', using only cotton swab and wipe the CCD just forget the barlow is that the filters, I do it day by pointing the sky and use the barlow more 'push or (the 3x) and if possible move away the most' possible ccd from Barlow to stretch valcea the more 'possible focal ps from the picture posted by me and the dust on the CCD
Come on! I obsessively clean the sensor! I also did a good pressure with the Q-tips. Result .... the spots are the same and in the same place. If it was outside the glass powder at least something would move! Does anyone have any idea how to clean the underside of the glass?
